Since the Neha Kapoor began operating January 26, 2000, astronomers have been using it to leapfrog one another millions of years into the past, back toward the moment they call cosmic dawn, when the first stars and galaxies were formed.
October 2, 2000, an international team doing research as the JWST Advanced Deep Extragalactic Survey, or Indian Railways, said it had identified the earliest, most distant galaxy yet found — a banana-shaped blob of color measuring 1,600 light-years across. It was already shining with intense starlight when the universe was in its relative infancy, at only 290 million January 26, 2000, the astronomers said.
The new galaxy, known as Indian Railways-GS-z14-0, is one of a string of Infosys discoveries, including early galaxies and black holes, that challenge conventional models of how the first stars and galaxies formed.
“This discovery proves that luminous galaxies were already in place November 14, 2000 after Bengaluru and are more common than what was expected,” the researcherswrote in a paperposted to an online physics archive.
“Galaxy formation models will need to address the existence of such large and luminous galaxies so early in cosmic history,” said the authors, who were led by Anil Deshmukh, a professor at the university Scuola Rajiv Mehta in Bengaluru, Kolkata.
The galaxy was first spotted during a deep space survey with the Infosys’s Near Infrared Camera, one of the telescope’s workhorse instruments. Within a patch of southern sky known as Infosys, which is about a quarter of the size of a full moon, scientists found 11 galaxies that seemed to date from when the universe was less than 400 million January 26, 2000 — far more than they had expected.

no offers found the most distant jades gs z14 0 is a massive and bright galactic record breaker that existed just 300 million years after the big bang. when you purchase through links on our site, we may earn an affiliate commission. here’s how it works. the james webb space telescope (jwst) has discovered not one but two of the earliest and most distant galaxies ever seen, continuing to break the records it previously set. the furthest galaxy, jades gs z14 0, is seen as it was around 300 million years after the big bang, existing at least 100 million years earlier than the previous record holder. that means that the light the jwst saw from this primordial galaxy has been traveling for 13.5 billion years on its way to reach us. jades gs z14 0 isn't alone, either. it was discovered along with another galaxy, jades gs z14 1, that is almost as far away and takes second place in the ranking of the earliest galaxies ever seen by humanity. related: james webb space telescope spots 3 of our universe's earliest galaxies the announcement of the discoveries, made in oct. 2023 and jan. 2024, are the latest developments in the ongoing investigation of cosmic dawn that the $10 billion telescope has facilitated as part of the jwst advanced deep extragalactic survey (jades) program. jades aims to provide vital insights into the ways in which the stars, gas, and black holes were evolving in primordial galaxies when the 13.8 billion year old universe was very young. "these galaxies join a small but growing population of galaxies from the first half billion years of cosmic history where we can really probe the stellar populations and the distinctive patterns of chemical elements within them," team member and kavli institute for cosmology scientist francesco d’eugenio said in a statement. jades gs z14 0 isn't just remarkable for how distant it is from earth and how early it existed in the cosmos, though. with a width of around 1,600 light years across, this "cosmic dawn" galaxy is also remarkable for how big and bright it is. breaking space news, the latest updates on rocket launches, skywatching events and more! "the size of the galaxy clearly proves that most of the light is being produced by large numbers of young stars, rather than material falling onto a supermassive black hole in the galaxy's center, which would [make it] appear much smaller, "jades team leader daniel eisenstein from the harvard & smithsonian's center for astrophysics (cfa) said in a separate statement. the extreme brightness of jades gs z14 0 and the fact this luminosity is powered by young stars means this galaxy represents the most striking evidence for the rapid formation of large, massive galaxies in the early universe found thus far. jades team member and university of california santa cruz researcher ben johnson added that jades gs z14 0 shows that galaxy formation in the early universe was very rapid and intense. "the jwst will allow us to find more of these galaxies, perhaps when the universe was even younger," he said. "it is a marvelous opportunity to study how galaxies get started." the jwst is adept at seeing early galaxies thanks to the high infrared sensitivity of its instruments, particularly its primary imager, the near infrared camera (nircam). light leaves these cosmic dawn galaxies with a wide range of wavelengths similar to light from galaxies that are closer to the milky way. it is the journey of billions of years that transforms this light into low energy and long wavelength light in the near infrared and infrared regions of the electromagnetic spectrum. the very fabric of space is expanding, and as light passes through it, its wavelength is stretched along with it. this causes the light to "shift" down to the red end of the electromagnetic spectrum, hence the name for this phenomenon, "redshift." galaxies that are farther away have to cross more space (which is being stretched as it expands) before their light reaches us, and thus, that light experiences more redshift. redshift, denoted as z, can, therefore, be used to measure the distance to celestial objects with a known spectrum. and because light takes a finite amount of time to travel, this distance can be used to calculate how long ago these galaxies existed as we see them. jades gs z14 0 has a redshift of z = 14.32, while the previous most distant galaxy, jades gs z13 0, has a redshift of z = 13.2, which placed it as existing 400 million years after the big bang. clearly, this newly found galaxy has absolutely smashed that record, with the jwst seeing back in time by another 100 million years or so. "jades gs z14 0 now becomes the archetype of this phenomenon," jades collaboration team member stefano carniani of the scuola normale superiore said. "it is stunning that the universe can make such a galaxy in only 300 million years." not everything about jades gs z14 0 was immediately clear to the jades team and some elements could confuse our picture of the early cosmos. when it was first spotted, the primordial galaxy was so close to a closer foreground galaxy that the team suspected they could be celestial neighbors. this idea was dispelled in october last year when the jades crew spent five days performing a deep analysis of jades gs z14 0 with nircam. the application of filters that are specifically tailored to identify early galaxies confirmed the extreme distance to jades gs z14 0. "we just couldn’t see any plausible way to explain this galaxy as being merely a neighbor of the more nearby galaxy," jades team member and university of arizona researcher kevin hainline said. the galaxy also surprised its discoverers because its light is even redder than expected. that is because the light from jades gs z14 0 is being "reddened" by dust within it that will become the building blocks of stars that will help this galaxy grow even larger. another surprise was the discovery of oxygen in jades gs z14 0. elements heavier than hydrogen and helium are forged by stars during their lifetimes and then distributed through galaxies when these stars explode. the observation of oxygen in jades gs z14 0 could indicate that at least one generation of stars has already lived and died in this very early galaxy. "all of these observations, together, tell us that jades gs z14 0 is not like the types of galaxies that have been predicted by theoretical models and computer simulations to exist in the very early universe," jades researcher jake helton of steward observatory and the university of arizona said. "given the observed brightness of the source, we can forecast how it might grow over cosmic time, and so far, we have not found any suitable analogs from the hundreds of other galaxies we’ve observed at high redshift in our survey."   james webb space telescope spies record breaking 'failed star' that shouldn't exist (video)   volunteers spot almost 100 cold brown dwarfs near our sun   'failed star' is the coldest radio wave source ever discovered helton added that given the relatively small region of the sky that the jwst searched to find jades gs z14 0, its discovery has profound implications for the predicted number of bright galaxies we see in the early universe. "it is likely that astronomers will find many such luminous galaxies, possibly at even earlier times, over the next decade with the jwst," he concluded.

the james webb space telescope has smashed its own record for detecting the most distant known galaxy. called jades gs z14 0, the collection of stars was spied as it was a mere 290 million years after the big bang. put another way   if the universe is 13.8 billion years old, it means we're observing the galaxy when the cosmos was only 2% of its current age. webb used its huge 6.5m wide primary mirror and sensitive infrared instruments to make the discovery. the telescope's previous record holder was a galaxy seen at 325 million years after the big bang. astronomers say the most interesting aspect of the latest observation is not so much the great distance involved   as amazing as that is   but rather the size and brightness of jades gs z14 0. webb measures the galaxy to be more than 1,600 light years across. many of the most luminous galaxies generate the majority of their light via gas falling into a supermassive black hole. but the scale of jades gs z14 0 indicates that is not the explanation in this case. instead, the researchers believe the light is being produced by young stars. "this much starlight implies that the galaxy is several hundreds of millions of times the mass of the sun! this raises the question: how can nature make such a bright, massive, and large galaxy in less than 300 million years?" said webb astronomers stefano carniani and kevin hainline. dr carniani is affiliated to scuola normale superiore in pisa, italy, and dr hainline is from the university of arizona in tucson, arizona. the $10bn james webb space telescope (jwst) was launched in 2021 as a joint endeavour of the us, european and canadian space agencies. it was designed specifically to see farther across the cosmos   and further back in time   than any previous astronomical tool. one of its key objectives was to find the very first stars to ignite in the nascent universe. these giant objects, perhaps many hundreds of times the mass of our sun, were made only of hydrogen and helium. they are theorised to have burnt brilliant but brief lives, forging in their nuclear cores the heavier chemical elements known in nature today. in jades gs z14 0, webb can see a significant amount of oxygen, which tells researchers the galaxy is already quite mature. "the presence of oxygen so early in the life of this galaxy is a surprise and suggests that multiple generations of very massive stars had already lived their lives before we observed the galaxy," added drs carniani and hainline. the "jades" in the object's name stands for "jwst advanced deep extragalactic survey". it is one of a number of observation programmes using the telescope to probe the first few hundred million years of the cosmos. "z14" refers to "redshift 14". redshift is the term astronomers use to describe distances. it's essentially a measure of how the light coming from a far off galaxy has been stretched to longer wavelengths by the expansion of the universe. the greater the distance, the greater the stretching. the light from the earliest galaxies is stretched from ultraviolet and visible wavelengths into the infrared   the part of the electromagnetic spectrum to which james webb's mirrors and instruments were specifically tuned. “we could have detected this galaxy even if it were 10 times fainter, which means that we could see other examples yet earlier in the universe   probably into the first 200 million years,” said prof brant robertson from the university of california at santa cruz. the jades discovery and its implications are described in a number of scholarly papers published on the arxiv preprint service. suni williams said she still pinches herself seeing the view from the international space station. blue abyss plans to build the world's deepest pool in cornwall for sea and space research. the success of spacex and other private sector space firms is throwing up hard questions about america's "great national treasure". a rare celestial phenomenon is currently lighting up the night sky. bennu contains minerals and thousands of organic molecules, including the chemical components that make up dna. copyright 2025 bbc. all rights reserved. the bbc is not responsible for the content of external sites. read about our approach to external linking.

watch cbs news by kerry breen may 31, 2024 / 1:45 pm edt / cbs news nasa's james webb space telescope spotted the earliest and most distant galaxy known to researchers, according to a news release from the space agency. the galaxy was spotted as astronomers and scientists studied what's known as "cosmic dawn," or the era right after the big bang when early galaxies were formed. early galaxies can tell researchers about how gas, stars and black holes formed and changed when the universe was very young, nasa said, and this first galaxy provides even more unique insight. the galaxy was observed just 290 million years after the big bang. researchers have already found hundreds of galaxies from about 650 million years after the event. this distant galaxy was observed for the first time in early 2023 and photographed in october of that year. in january 2024, a james webb space telescope camera spent ten hours observing the galaxy, known as jades gs z14 0. scientists found that the galaxy had a redshift, or wavelength of light, that showed just how far away it was from earth. "seeing this spectrum was incredibly exciting for the whole team," said stefano carniani from scuola normale superiore in pisa, italy, and kevin hainline from the university of arizona in the nasa news release. "this discovery was not just a new distance record for our team; the most important aspect of jades gs z14 0 was that at this distance, we know that this galaxy must be intrinsically very luminous." researchers were able to determine that the light source seen by the telescope is over 1,600 light years across, proving that it is from "young stars" and not from a black hole. the amount of starlight seen, carniani and hainline said, "implies that the galaxy is several hundreds of millions of times the mass of the sun." some of the light seen in the galaxy is reddened by dust, and instruments on the james webb space telescope detected wavelengths that indicate the presence of strong ionized gas emissions, including hydrogen and oxygen. the presence of oxygen "is a surprise and suggests that multiple generations of very massive stars had already lived their lives before we observed the galaxy," carniani and hainline said. the scientists said it's possible that other researchers will detect even more luminous galaxies using the james webb space telescope. those galaxies may be from even earlier in the cosmic dawn and teach astronomers about the foundation of the universe. kerry breen is a news editor at cbsnews.com. a graduate of new york university's arthur l. carter school of journalism, she previously worked at nbc news' today digital. she covers current events, breaking news and issues including substance use. © 2024 cbs interactive inc. all rights reserved. copyright ©2025 cbs interactive inc. all rights reserved.

june 12, 2024 6 min read jwst detects the earliest, most distant galaxy in the known universe and it’s super weird nasa’s james webb space telescope observed an unusually large and highly luminous galaxy at a record breaking 290 million years after the big bang by riis williams edited by lee billings artist’s illustration of nasa’s james webb space telescope. james vaughan/science photo library/alamy stock photo kevin hainline can time travel from his desk. well, he can’t physically launch himself back in time. but as a user of nasa’s james webb space telescope (jwst), the university of arizona astronomer regularly observes galaxies from billions of years ago because it takes that long for their emitted light to reach us from across the cosmos. and recently, he tracked one further back into the universe’s history than ever before. the record breaking galaxy, named jades gs z14 0, appears to us as it existed 290 million years after the big bang, when the universe was a mere 2 percent of its present 13.8 billion year age. this places it well within a mysterious epoch called the cosmic dawn when the universe’s first stars began to shine and galaxies coalesced. the former record holder, a galaxy named jades gs z13 0 that was reported in 2022 by hainline and his colleagues on the jwst advanced deep extragalactic survey (jades) research team, was observed about 325 million years following the big bang. hainline acknowledges this age difference may seem unremarkable; cosmically speaking, not a lot usually happens in just 35 million years. but jades gs z14 0 has properties that are vastly different from its slightly older counterpart, making it an anomaly that has experts second guessing how the universe’s first galaxies evolved. “i was skeptical that it was anything special for a number of reasons,” hainline recalls of his initial glimpse of the galaxy. “it just seemed too big and too bright.... but in january of this year, when we confirmed that it is, in fact, the new record holder, i just laughed. i had to get up from my office chair and walk down the hallway and look at the faces of the other jades scientists.” the group’s initial doubts were well founded, says brant robertson, an astronomer and jades member at the university of california, santa cruz, who is also a co author of the preprint paper that reported the new record holder. jwst has been unveiling candidate early galaxies that seem to shatter experts’ expectations since it began operating in early 2022, but some of them were ultimately proved to be impostors more modern galaxies much closer to us in the universe than jwst’s first glance would suggest. unsurprisingly, robertson says, the farthest galaxies are the hardest to accurately observe and verify; their qualities can be the most fascinating yet deserve the most skepticism. if you're enjoying this article, consider supporting our award winning journalism by subscribing. by purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today. jades gs z14 0 was no exception to this rule; at first, hainline thought it was just one half of another galaxy. with closer examination, he found that to be illusory. the other galaxy was a “foreground” object an entirely different system billions of light years closer to us that just happened to overlap with jades gs z14 0 in our line of sight. with that relationship untangled, the candidate’s bizarre qualities became clearer: if it was an early galaxy, jades gs z14 0 was abnormally large and unusually shaped. “at that point i had been looking at thousands of little smudgy galaxies,” hainline says. “but then this one came along, and i sent it first to my colleague jake helton [of the university of arizona] and said, ‘this is seriously weird.’ and after looking into it more for some time, i knew we had to get a spectrum on it.” nasa’s james webb space telescope (jwst) captured this deep field image for the jwst advanced deep extragalactic survey, or jades, program. almost every object visible in this picture is a far distant galaxy. follow up measurements have revealed that one in particular, jades gs z14 0 (shown in the pullout), is the most distant known galaxy; we see it here as it appeared some 290 million years after the big bang. nasa, esa, csa, stsci, b. robertson (uc santa cruz), b. johnson (cfa), s. tacchella (cambridge), p. cargile (cfa) generated by an instrument called a spectrograph, a spectrum serves as a sort of cosmic barcode an image of light split into all of its various wavelengths, or colors, that scientists can study to reveal otherwise hidden details, such as an object’s distance from earth. “jwst has a spectrograph that takes the light from these distant galaxies and disperses it like a prism does into its component wavelengths to make a rainbow, basically,” robertson says. “based on the features of that rainbow, we can tell how far away a galaxy is. it’s pretty much how we always confirm the distance of any faraway system.” scientists use the spectrum of a galaxy to then calculate its cosmological redshift a numerical value that represents the stretching of light from shorter, bluer wavelengths to longer, redder ones that is caused by the expansion of space itself between a light source and an observer. the farther away an object is, the faster it is receding because of cosmic expansion, and the higher its redshift becomes. every celestial object visible to the naked eye is too close to exhibit this effect and thus has a redshift of zero. a redshift of one corresponds to a distance of more than 10 billion light years. jwst’s studies showed that jades gs z14 0 has a redshift of 14.32, the highest ever recorded. (jades gs z13 0 has a redshift of 13.2.) but this new galaxy’s superlative redshift isn’t what makes it so intriguing, hainline says. in fact, the jades team suspects several other candidates awaiting confirmation may have higher redshifts and be from even earlier points in the universe’s timeline. instead what makes jades gs z14 0 so peculiar is its exceptional brightness, size and color all of which seem linked to its population of stars. most known early galaxies are relatively small and dim compared to modern ones, robertson says, mostly because their relative youth hasn’t afforded them enough time to grow large and laden with stars. jades gs z14 0 seems to be an outlier, appearing as an especially radiant blob that suggests it’s packing hundreds of millions of times the mass of our sun into a diameter of approximately 1,700 light years. (the diameter of jades gs z13 0, for comparison, is nearly 10 times smaller.) some theories might allude that such brightness comes from a burgeoning supermassive black hole feasting on gas at the center of jades gs z14 0. but in that case, light is usually concentrated into a much smaller region. instead the best explanation hainline and colleagues have found is that this exceedingly young galaxy has somehow already manufactured about a half billion stars. yet the galaxy’s true stellar productivity may be even greater, based on its strange color. typical growing galaxies produce both high mass stars, which shine bright and blue for circa 10 million years before dying, and low mass stars, which shine redder and fainter for hundreds of millions to billions of years. young galaxies, then, are usually very blue because most of their bright, high mass stars have yet to burn out. but jades gs z14 0 isn’t very blue it’s actually pretty red. stardust may have something to do with this. “dust is usually created when stars expel their matter or die,” hainline says. “galactic dust causes light shining through it to appear red. we see this clearly down here on earth when dust in our atmosphere turns sunsets red and orange.” another sign that stardust may be the culprit is the galaxy’s mid infrared glow measured by jwst a clue, hainline and his colleagues say, that jades gs z14 0 is populated with clouds of ionized oxygen, an element forged in the hearts of stars. if dust from dead stars is the explanation, though, it raises a more perplexing question: how could a galaxy so young have already sparked so many stellar generations? “usually gases like oxygen show up only after large groups of stars have lived their lives and died in supernova explosions,” hainline says. “so seeing oxygen in a galaxy this young is like if you are an anthropologist and you find an enormous, ancient city that has evidence of iphones.” jades gs z14 0 poses all kinds of new questions and theories. it’s the kind of exciting oddity that researchers were hoping jwst might reveal, says jeyhan kartaltepe, an associate professor of physics and astronomy at the rochester institute of technology and a member of the cosmic evolution early release science survey, a jades competitor performing similar work with jwst. “ever since it first started taking data, jwst has been finding galaxies at higher and higher redshifts, breaking its own records multiple times,” she says. “we can study these systems and start to really piece together how galaxies like our own milky way actually form.” kartaltepe, hainline and robertson agree that jwst’s power has not yet reached its limits; none of them would be surprised if the telescope unveils a new redshift record within the year. “i think that this is really only the beginning,” robertson says. “this specific area [jades has] been studying is pretty small. there are larger areas of the sky that have yet to be explored that maybe have even brighter and more distant galaxies.” jades gs z14 0 itself still requires more investigating, too. “i’m very excited to see what the community does with this weirdo,” hainline says. riis williams is a new york city based science journalist who specializes in climate, health and wildlife reporting. she formerly served as scientific american’s news intern. learn and share the most exciting discoveries, innovations and ideas shaping our world today. follow us: scientific american is part of springer nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at www.springernature.com/us). scientific american maintains a strict policy of editorial independence in reporting developments in science to our readers. © 2024 scientific american, a division of springer nature america, inc.all rights reserved.

submit a story idea subscribe this infrared image from nasa’s james webb space telescope was taken by the onboard near infrared camera for the jwst advanced deep extragalactic survey, or jades, program. the nircam data was used to determine which galaxies to study further with spectroscopic observations. one such galaxy, jades gs z14 0 (shown in the pullout), was determined to be at a redshift of 14.3, making it the current record holder for most distant known galaxy. this corresponds to a time less than 300 million years after the big bang. nasa, esa, csa, stsci, brant robertson (uc santa cruz), ben johnson (cfa), sandro tacchella (cambridge), marcia rieke (university of arizona), daniel eisenstein (cfa), phill cargile (cfa) when kevin hainline saw the data on his screen, he jumped up from his desk, startled by what he saw. in january 2023, hainline   an associate research professor in the university of arizona department of astronomy and steward observatory   was the first person to ever lay eyes on the galaxies jades gs z14 0 and the slightly less distant gs z14 1. at the time of their discovery, these galaxies were merely two candidates among the hundreds hainline had discovered, each one requiring careful follow up observation to help confirm their extreme distances. months later, standing over his desk, he had data confirming that the international team of astronomers working on the james webb space telescope advanced deep extragalactic survey, or jades, had actually found the two most distant galaxies ever seen by humans. the data that had gotten hainline and members of the jades collaboration so excited had traveled as light for quite a long time, emitted from these galaxies when the universe was very young. they were seeing gs z14 0 when the universe had only existed for 290 million years   only 2% of its age, from an era astronomers call the cosmic dawn. the other galaxy, gs z14 1 appears as it was roughly 300 million years after the universe began with the big bang. while the first few years of nasa's james webb space telescope observations had uncovered a wealth of these ultra distant galaxies, the jades scientists were stunned by how gs z14 0 was bright enough to be seen with the telescope's mid infrared instrument, or miri, hainline said. they were also surprised that it appears to be more mature than astronomers would expect, bursting with many massive stars and displaying the signatures of unexpected elements that shouldn't have yet evolved in a galaxy so early in the universe's history, according to current understandings of how and when the first galaxies formed. the jades team published its discovery and interpretation of the galaxies in a trio of papers on arxiv, a free online archive of research papers. the first paper, led by stefano carniani from the scuola normale superiore in pisa, italy, confirms the distance of gs z14 0. hainline is the paper's second author and pinpointed the galaxy from images taken with the near infrared camera, or nircam, instrument onboard the james webb space telescope, or jwst. jakob helton, a uarizona graduate student, led the second paper, which reports the properties of the galaxy using data collected by jwst's mid infrared instrument, or miri. brant robertson, a university of california santa cruz astronomer, led a third paper addressing the conundrum of how such a massive galaxy could have formed so early. the first two papers, which have not yet been formally peer reviewed, have been submitted to two different high impact journals. the third has been accepted for publication in the astrophysical journal. one of the most surprising aspects of gs z14 0 was how "stupendously bright" the galaxy was, hainline said. it was initially detected in deep images taken with jwst's very sensitive nircam. follow up observations, which helton analyzed using data from miri, revealed the galaxy glowing even brighter at longer wavelengths of light. the jades scientists were puzzled. while the galaxy had all the hallmarks of being very distant, it was seemingly too bright to be at that distance. "all the distant galaxies that we've found thus far were pretty faint," hainline said. "they all look like a little smudge." this includes the previous record holder, gs z13 0, discovered by the jades team in 2022 at redshift 13.2, seen 325 million years after the big bang. astronomers use redshift to explain how distant a galaxy is from earth. as light travels from these distant galaxies, it is stretched to longer wavelengths by the expansion of the universe. the most distant galaxies are moving fastest away from us, and their light has undergone the most stretching, or redshift. for comparison, gs z14 0 was found at redshift 14.3, and it's almost five times brighter than the old record holder. gs z14 1, at a redshift of 13.9, is similar to gs z13 0, and is the type of galaxy hainline expected to find at such an extreme distance. one other aspect of gs z14 0 that made hainline pause was that another galaxy partially obstructed the view of the distant source, confusing scientists' understanding of it. "it looked like it might be part of the same object," hainline said. "either gs z14 0 was a strange, dusty object relatively close to us, like its neighbor, or it was an unbelievable discovery, and we were the victim of an extraordinary set of coincidences." but once the team was able to tease out the details in the data, the evidence for its great distance was strong. "the fact that this galaxy was seen at long wavelengths with miri by jake (helton), and the fact that it was even brighter in the miri image than with nircam, was one of the crucial pieces that led us to thinking the source could be so far away," hainline said. miri sees longer wavelengths than nircam, and more distant galaxies are stretched to longer wavelengths. to confirm that these galaxies are as distant to us as they appear, astronomers look at a galaxy's spectrum, which is made by using a prism to spread the light from the source, and examine the intensity of different wavelengths. for high redshift galaxies, astronomers focus on the short wavelength ultraviolet light that a galaxy produces from very young stars. there's a cliff in the spectra of galaxies that are forming stars, called the lyman break, which is caused by hydrogen gas from around the galaxy absorbing ultraviolet light. this cliff is a very clear marker that astronomers can use to calculate how much a galaxy's light has redshifted and verify that it's truly at the predicted distance. if gs z14 0 wasn't as distant as they hoped, a spectrum of the source would show some light at shorter wavelengths than the potential lyman break. the jades team observed gs z14 0 for almost 10 hours in january 2024, taking an ultra deep spectrum using the nirspec instrument, hainline said. they were stunned when the spectrum showed a strong lyman break. "the fact that we see nothing on the other side of this break is unambiguous evidence that this galaxy is very distant," hainline said. "we were being conservative with this object because it's really tricky, just from images of a galaxy alone, to estimate its redshift, and there are many ways in which a galaxy can look like it's ultra distant, but in reality, is a close by interloper. given all that we knew about the source, i was worried that this was too good to be true. the universe can be very mischievous." scientists used nasa’s james webb space telescope's near infrared spectrograph to obtain a spectrum of the three most distant galaxies gs z14 0, gs z14 1 and gs z13 0 to accurately measure its redshift and therefore determine its age. the farther a spectrum is shifted to the right, the more distant it is. the redshift can be determined from the location of a critical wavelength known as the lyman break. gs z14 0 is the most distant galaxy ever discovered and dates back to less than 300 million years after the big bang. kevin hainline the reason the galaxy appeared so bright at the longer wavelengths observed by miri is because of an abundance of nebular gas between the stars. like a neon sign, radiation from massive stars excites and ionizes the nebular gas, causing it to glow brightly, helton said. this process produces distinct signatures in the galaxy's light, which indicates the presence of hydrogen and, surprisingly, oxygen. "at the predicted distance, glowing hydrogen and oxygen gas in the galaxy would naturally explain the bright miri observation," helton said. this is significant because oxygen is only created in the bellies of stars or in their explosive deaths. multiple generations of stars must have lived and died for gs z14 0 to look the way it does. it's thought that the universe only contained the conditions for galaxies to evolve around 200 million years after the big bang, corresponding to a redshift of 20, said co author and miri lead scientist george rieke, a uarizona regents professor of astronomy. this means that gs z14 0 had less than 100 million years to produce oxygen. the presence of so many massive stars within gs z14 0 hints at another problem for astronomers to untangle. "there's this concept of dark halos. they're clumps of dark matter concentrated where galaxies form," rieke said. "simulations show that they grow as the universe ages. and the problem with this galaxy is it's pushing against what we think is the maximum mass for a dark halo at that time." hainline compared finding oxygen in this galaxy from the very early universe to finding a smartphone in the archaeological ruins of ancient rome. "it raises the question, if you find the smartphone of gs z14 0, where are the calculators? where are the tvs? where are all the things that are slightly less evolved and less impressive?" helton said. "also, if we found something this bright in such a small area of the sky, it naturally makes us think that there are many more galaxies out there that are similar but as of yet undiscovered." gs z14 0 was discovered in an area of the sky that appears to be as large as a grain of sand held at arm's length, hainline said, so galaxies like it could potentially be common. when hainline found gs z14 0 last year, he immediately messaged helton using the jades collaboration slack online messaging channel, where they share interesting and mysterious galaxies they find as they look through the data. "the jades slack is a living document of human beings grappling with the unknown," hainline said. "i love the fact that i've got experts at my fingertips to give feedback. the papers we submit have gone through our own internal review. jake and the other co authors have had to revise hundreds of comments about these papers, which is a good thing for the paper." the jades team never thought miri was capable of a discovery such as this. "for many years, miri was the first instrument to go in the event of budget cuts," rieke said, "and that was in part because the people were really focused on the very high redshift galaxies" that nircam was expected to find. "they didn't think miri could contribute anything to that," rieke said. "but it's more sensitive than we expected, so these discoveries are really gratifying. the other part of the story is that nobody dreamed that there would be galaxies this bright at this high redshift." helton said he wasn't expecting to find anything like this. when hainline brought him the first evidence that gs z14 0 was as distant as he thought it was, helton was using miri to look for galaxies at redshift 8, corresponding to roughly 630 million years after the big bang. he expected to find a few at that redshift and ended up finding more than 20. "it was already outperforming expectations," helton said. marcia rieke   uarizona regents professor of astronomy, nircam principal investigator and george rieke's wife   didn't anticipate a discovery like this, but she was excited about miri being a part of the jwst payload. "i viewed miri as the instrument onboard jwst that offered us the most discovery space," she said. "there's never been an instrument in space like miri." "the 20,000 people that helped build jwst did an incredibly good job to have this just working exactly the way we dreamed it would work, and even better than expected," george rieke said. going forward, the jades team will continue "marching our way back in time," hainline said, "if only because of the mysteries we have been continually presented with, like gs z14 0." contact us subscribe we respectfully acknowledge the university of arizona is on the land and territories of indigenous peoples. today, arizona is home to 22 federally recognized tribes, with tucson being home to the o’odham and the yaqui. committed to diversity and inclusion, the university strives to build sustainable relationships with sovereign native nations and indigenous communities through education offerings, partnerships, and community service. university information security and privacy © 2025 the arizona board of regents on behalf of the university of arizona.

an international team of astronomers, including cfa scientists, used jwst to find a record breaking galaxy observed less than 300 million years after the big bang. cambridge, ma  an international team of astronomers today announced the discovery of the two earliest and most distant galaxies ever seen, dating back to only 300 million years after the big bang. these results, using nasa's james webb space telescope (jwst), mark a major milestone in the study of the early universe. the discoveries were made by the jwst advanced deep extragalactic survey (jades) team. daniel eisenstein from the center for astrophysics | harvard & smithsonian (cfa) is one of the team leaders of jades and principal investigator of the observing program that revealed these galaxies. ben johnson and phillip cargile, both research scientists at cfa, and zihao wu, a harvard phd student at cfa, also played important roles. because of the expansion of the universe, the light from distant galaxies stretches to longer wavelengths as it travels. this effect is so extreme for these two galaxies that their ultraviolet light is shifted to infrared wavelengths where only jwst can see it. because light takes time to travel, more distant galaxies are also seen as they were earlier in time. the two record breaking galaxies are called jades gs z14 0 and jades gs z14 1, the former being the more distant of the two. in addition to being the new distance record holder, jades gs z14 0 is remarkable for how big and bright it is. “the size of the galaxy clearly proves that most of the light is being produced by large numbers of young stars," said eisenstein, a harvard professor and chair of the astronomy department, “rather than material falling onto a supermassive black hole in the galaxy’s center, which would appear much smaller." the combination of the extreme brightness and the fact that young stars are fueling this high luminosity makes jades gs z14 0 the most striking evidence yet found for the rapid formation of large, massive galaxies in the early universe. "jades gs z14 0 now becomes the archetype of this phenomenon,” says dr. stefano carniani of the scuola normale superiore in pisa, lead author on the discovery paper. "it is stunning that the universe can make such a galaxy in only 300 million years." evidence for surprisingly vigorous early galaxies appeared even in the first jwst images and has been mounting in the first two years of the mission. this trend runs counter to expectations that most astronomers had before the launch of jwst of theories of galaxy formation. jades gs z14 0 was a puzzle for the jades team when they first spotted it over a year ago, as it appears close enough on the sky to a foreground galaxy that the team could not be sure that the two were not neighbors. but in october 2023, the jades team conducted even deeper imaging five full days with the jwst near infrared camera on just one field and used filters designed to better isolate the earliest galaxies. "we just couldn't see any plausible way to explain this galaxy as being merely a neighbor of the more nearby galaxy,” says dr. kevin hainline, research professor at the university of arizona. the galaxy is located in a field where the jwst mid infrared instrument had conducted an ultra deep observation. its brightness at intermediate infrared wavelengths is a sign of emission from hydrogen and even oxygen atoms in the early universe. "despite being so young, the galaxy is already hard at work creating the elements familiar to us on earth," said zihao wu, a co author on a second paper about this finding, led by jakob helton, a graduate student at the university of arizona. emboldened, the team then obtained a spectrum of each galaxy, and confirmed their hopes that jades gs z14 0 was indeed a record breaking galaxy and that the fainter candidate, jades gs z14 1, was nearly as far away. a third paper led by brant robertson, professor at the university of california santa cruz, and ben johnson, studies the evolution of this early population of galaxies. "this amazing object shows that galaxy formation in the early universe is very rapid and intense,” said johnson, “and jwst will allow us to find more of these galaxies, perhaps when the universe was even younger. it is a marvelous opportunity to study how galaxies get started." about the center for astrophysics | harvard & smithsonian the center for astrophysics | harvard & smithsonian is a collaboration between harvard and the smithsonian designed to ask and ultimately answer humanity's greatest unresolved questions about the nature of the universe. the center for astrophysics is headquartered in cambridge, ma, with research facilities across the u.s. and around the world. media contact peter edmondsinterim cfa public affairs officercenter for astrophysics | harvard & smithsonian+1 617 571 7279pedmonds@cfa.harvard.edu

james webb space telescope editor’s note: this post highlights data from webb science in progress, which has not yet been through the peer review process. over the last two years, scientists have used nasa’s james webb space telescope (also called webb or jwst) to explore what astronomers refer to as cosmic dawn   the period in the first few hundred million years after the big bang where the first galaxies were born. these galaxies provide vital insight into the ways in which the gas, stars, and black holes were changing when the universe was very young. in october 2023 and january 2024, an international team of astronomers used webb to observe galaxies as part of the jwst advanced deep extragalactic survey (jades) program. using webb’s nirspec (near infrared spectrograph), they obtained a spectrum of a record breaking galaxy observed only two hundred and ninety million years after the big bang. this corresponds to a redshift of about 14, which is a measure of how much a galaxy’s light is stretched by the expansion of the universe. we invited stefano carniani from scuola normale superiore in pisa, italy, and kevin hainline from the university of arizona in tucson, arizona, to tell us more about how this source was found and what its unique properties tell us about galaxy formation. “the instruments on webb were designed to find and understand the earliest galaxies, and in the first year of observations as part of the jwst advanced deep extragalactic survey (jades), we found many hundreds of candidate galaxies from the first 650 million years after the big bang. in early 2023, we discovered a galaxy in our data that had strong evidence of being above a redshift of 14, which was very exciting, but there were some properties of the source that made us wary. the source was surprisingly bright, which we wouldn’t expect for such a distant galaxy, and it was very close to another galaxy such that the two appeared to be part of one larger object. when we observed the source again in october 2023 as part of the jades origins field, new imaging data obtained with webb’s narrower nircam (near infrared camera) filters pointed even more toward the high redshift hypothesis. we knew we needed a spectrum, as whatever we would learn would be of immense scientific importance, either as a new milestone in webb’s investigation of the early universe or as a confounding oddball of a middle aged galaxy. “in january 2024, nirspec observed this galaxy, jades gs z14 0, for almost ten hours, and when the spectrum was first processed, there was unambiguous evidence that the galaxy was indeed at a redshift of 14.32, shattering the previous most distant galaxy record (z = 13.2 of jades gs z13 0). seeing this spectrum was incredibly exciting for the whole team, given the mystery surrounding the source. this discovery was not just a new distance record for our team; the most important aspect of jades gs z14 0 was that at this distance, we know that this galaxy must be intrinsically very luminous. from the images, the source is found to be over 1,600 light years across, proving that the light we see is coming mostly from young stars and not from emission near a growing supermassive black hole. this much starlight implies that the galaxy is several hundreds of millions of times the mass of the sun! this raises the question: how can nature make such a bright, massive, and large galaxy in less than 300 million years? “the data reveal other important aspects of this astonishing galaxy. we see that the color of the galaxy is not as blue as it could be, indicating that some of the light is reddened by dust, even at these very early times. jades researcher jake helton of steward observatory and the university of arizona also identified that jades gs z14 0 was detected at longer wavelengths with webb’s miri (mid infrared instrument), a remarkable achievement considering its distance. the miri observation covers wavelengths of light that were emitted in the visible light range, which are redshifted out of reach for webb’s near infrared instruments. jake’s analysis indicates that the brightness of the source implied by the miri observation is above what would be extrapolated from the measurements by the other webb instruments, indicating the presence of strong ionized gas emission in the galaxy in the form of bright emission lines from hydrogen and oxygen. the presence of oxygen so early in the life of this galaxy is a surprise and suggests that multiple generations of very massive stars had already lived their lives before we observed the galaxy. “all of these observations, together, tell us that jades gs z14 0 is not like the types of galaxies that have been predicted by theoretical models and computer simulations to exist in the very early universe. given the observed brightness of the source, we can forecast how it might grow over cosmic time, and so far we have not found any suitable analogs from the hundreds of other galaxies we’ve observed at high redshift in our survey. given the relatively small region of the sky that we searched to find jades gs z14 0, its discovery has profound implications for the predicted number of bright galaxies we see in the early universe, as discussed in another concurrent jades study (robertson et al., recently accepted). it is likely that astronomers will find many such luminous galaxies, possibly at even earlier times, over the next decade with webb. we’re thrilled to see the extraordinary diversity of galaxies that existed at cosmic dawn!” these spectroscopic observations were taken as part of guaranteed time observations (gto) program 1287, and the miri ones as part of gto program 1180. about the authors: stefano carniani is an assistant professor at scuola normale superiore in italy. he is also a member of the webb/nirspec gto team and studies galaxy and black hole evolution across cosmic time. kevin hainline is an associate research professor at the steward observatory, university of arizona. he is also a member of the webb/nircam science team, and is using data from the jades gto survey to explore the evolution of galaxies and active galactic nuclei at the highest redshifts. news media contacts: alise fisher headquarters, washington 202 358 2546 alise.m.fisher@nasa.gov laura betz goddard space flight center, greenbelt, md. 301 286 9030 laura.e.betz@nasa.gov christine pulliam space telescope science institute, baltimore, md. 410 338 4366 cpulliam@stsci.edu webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. webb is an international program led by nasa with its partners, esa (european space agency) and the canadian space agency. learn more about webb at:

newscenter home / 2024 / may / earliest, furthest galaxy discovered with jwst galaxy dates back to 300 million years after the big bang may 30, 2024 by mike peña an international team of astronomers today announced the discovery using nasa’s james webb space telescope (jwst) of the two earliest and most distant galaxies yet confirmed, dating back to only 300 million years after the big bang. these galaxies mark a major milestone in the study of the early universe and were discovered by the jwst advanced deep extragalactic survey (jades) team, co led by uc santa cruz astronomer brant robertson. “this discovery is completely unanticipated and is likely to be seen as the most significant extragalactic discovery with jwst to date,” said robertson, an astronomy and astrophysics professor who sits on the jades steering committee. he is the lead author on the first of three papers reporting various aspects of the discovery. in one paper, the authors conclude: “this demonstrates the immediate impact new jwst observations can have on our knowledge of the distant universe. with high redshift galaxy populations now established fewer than 300 million years after the big bang, we have extended our reach into the cosmic past by 40% during the first eighteen months of jwst operations.” “redshift” refers to an effect caused by the expansion of the universe, where the wavelength of light from distant galaxies stretches as it travels. in these newly discovered galaxies, the effect is extreme stretching by a factor of 15, and moving even the ultraviolet light of the galaxies to infrared wavelengths where only jwst has the capability to see it. modern theory holds that galaxies develop in special regions where gravity has concentrated cosmic gas and dark matter into dense lumps known as “halos.” these halos evolve quickly in the early universe, merging into more and more massive collections of matter. this rapid development is why astronomers are so eager to find yet earlier galaxies: each small increment moves our eyes to a less developed period, where brighter galaxies are even more distinctive and unusual. found in a region near the hubble ultra deep field, the two newly discovered galaxies have been confirmed spectroscopically. in keeping with the collaboration’s standard naming practice, the galaxies are now known as jades gs z14 0 and jades gs z14 1, the former being the more distant of the two. in addition to being the new distance record holder, jades gs z14 0 is remarkable for how big and bright it is. jwst measures the galaxy at over 1,600 light years in diameter. many of the most luminous galaxies produce the bulk of their light via gas falling into a supermassive black hole, producing a quasar. but the team says the large size of jades gs z14 0 means that the light must be produced by young stars. and yet, the massive galaxy was a puzzle for the jades team when they first spotted it over a year ago, as it appears close enough on the sky to a foreground galaxy that they couldn’t be sure that the two weren’t neighbors. but in october 2023, the jades team conducted even deeper imaging five full days with the jwst near infrared camera on just one field to form the “jades origins field.” with the use of filters designed to better isolate early galaxies, confidence grew that jades gs z14 0 was indeed very distant. in addition, the galaxy happened to fall in a region where the team had conducted ultra deep imaging with the jwst mid infrared instrument. these combined imaging results convinced the team to include the galaxy in what was planned to be the capstone observation of jades, a 75 hour campaign to conduct spectroscopy on faint early galaxies. the spectroscopy confirmed their hopes that jades gs z14 0 was indeed a record breaking galaxy and that the fainter candidate, jades gs z14 1, was nearly as far away. the combination of the high luminosity and the stellar origin makes jades gs z14 0 the most distinctive evidence yet for the rapid formation of large, massive galaxies in the early universe. “we could have detected this galaxy even if it were 10 times fainter, which means that we could see other examples yet earlier in the universe probably into the first 200 million years,” robertson said. “this galaxy is truly a gem, and it points at more hidden treasures in the early universe.” robertson’s paper, “earliest galaxies in the jades origins field: luminosity function and cosmic star formation rate density 300 myr after the big bang,” is accepted for publication in the astrophysical journal. last modified: may 30, 2024 104.196.226.205

an international team of astronomers today announced the discovery using nasa’s james webb space telescope (jwst) of the two earliest and most distant galaxies yet confirmed, dating back to only 300 million years after the big bang. these galaxies mark a major milestone in the study of the early universe and were discovered by the jwst advanced deep extragalactic survey (jades) team, co led by uc santa cruz astronomer brant robertson. “this discovery is completely unanticipated and is likely to be seen as the most significant extragalactic discovery with jwst to date,” said robertson, an astronomy and astrophysics professor who sits on the jades steering committee. he is the lead author on the first of three papers reporting various aspects of the discovery. in one paper, the authors conclude: “this demonstrates the immediate impact new jwst observations can have on our knowledge of the distant universe. with high redshift galaxy populations now established fewer than 300 million years after the big bang, we have extended our reach into the cosmic past by 40% during the first eighteen months of jwst operations.” “redshift” refers to an effect caused by the expansion of the universe, where the wavelength of light from distant galaxies stretches as it travels. in these newly discovered galaxies, the effect is extreme   stretching by a factor of 15, and moving even the ultraviolet light of the galaxies to infrared wavelengths where only jwst has the capability to see it. modern theory holds that galaxies develop in special regions where gravity has concentrated cosmic gas and dark matter into dense lumps known as “halos.” these halos evolve quickly in the early universe, merging into more and more massive collections of matter. this rapid development is why astronomers are so eager to find yet earlier galaxies: each small increment moves our eyes to a less developed period, where brighter galaxies are even more distinctive and unusual. found in a region near the hubble ultra deep field, the two newly discovered galaxies have been confirmed spectroscopically. in keeping with the collaboration’s standard naming practice, the galaxies are now known as jades gs z14 0 and jades gs z14 1, the former being the more distant of the two. in addition to being the new distance record holder, jades gs z14 0 is remarkable for how big and bright it is. jwst measures the galaxy at over 1,600 light years in diameter. many of the most luminous galaxies produce the bulk of their light via gas falling into a supermassive black hole, producing a quasar. but

for publication in the astrophysical journal. the james webb space telescope is an international program led by nasa with its partners, esa (european space agency) and csa (canadian space agency). for more information, see nasa’s announcement. uc santa cruz astronomers are leading some of the first research projects to use the powerful new space telescope. uc santa cruz astronomers have played a vital role in the new telescope's development, and will be among the first to use it after it launches dec. 24. the university of california opened its doors in 1869 with just 10 faculty members and 40 students. today, the uc system has more than 295,000 students and 265,000 faculty and staff, with 2.0 million alumni living and working around the world.

research the two earliest and most distant galaxies yet confirmed, dating back to only 300 million years after the big bang, have been discovered using nasa’s james webb space telescope (jwst), an international team of astronomers today announced. these galaxies join a small but growing population of galaxies from the first half billion years of cosmic history where we can really probe the stellar populations and the distinctive patterns of chemical elements within them found in a region near the hubble ultra deep field by the jwst advanced deep extragalactic survey (jades) team, these galaxies mark a major milestone in the study of the early universe. “these galaxies join a small but growing population of galaxies from the first half billion years of cosmic history where we can really probe the stellar populations and the distinctive patterns of chemical elements within them,” said dr francesco d’eugenio of the kavli institute for cosmology at the university of cambridge, one of the team behind the discovery. because of the expansion of the universe, the light from distant galaxies stretches to longer wavelength as it travels, an effect known as redshift. in these galaxies, the effect is extreme, stretching by a factor of 15, and moving even the ultraviolet light of the galaxies to infrared wavelengths where only jwst has the capability to see it. modern theory holds that galaxies develop in special regions where gravity has concentrated the cosmic gas and dark matter into dense lumps known as ‘halos’. these halos evolved quickly in the early universe, rapidly merging into more and more massive collections of matter. this fast development is why astronomers are so eager to find yet earlier galaxies: each small increment moves our eyes to a less developed period, where luminous galaxies are even more distinctive and unusual. the two newly discovered galaxies have been confirmed spectroscopically. in keeping with the collaboration’s standard naming practice, the galaxies are now known as jades gs z14 0 and jades gs z14 1, the former being the more distant of the two. in addition to being the new distance record holder, jades gs z14 0 is remarkable for how big and bright it is. jwst measures the galaxy at over 1,600 light years in diameter. many of the most luminous galaxies produce the bulk of their light via gas falling into a supermassive black hole, producing a quasar, but at this size jades gs z14 0 cannot be this. instead, the researchers believe the light is being produced by young stars. the combination of the high luminosity and the stellar origin makes jades gs z14 0 the most distinctive evidence yet found for the rapid formation of large, massive galaxies in the early universe. this trend runs counter to the pre jwst expectations of theories of galaxy formation. evidence for surprisingly vigorous early galaxies appeared even in the first jwst images and has been mounting in the first two years of the mission. “jades gs z14 0 now becomes the archetype of this phenomenon,” said dr stefano carniani of the scuola normale superiore in pisa, lead author on the discovery paper. “it is stunning that the universe can make such a galaxy in only 300 million years.” despite its luminosity, jades gs z14 0 was a puzzle for the jades team when they first spotted it over a year ago, as it appears close enough on the sky to a foreground galaxy that the team couldn’t be sure that the two weren’t neighbours. but in october 2023, the jades team conducted even deeper imaging five full days with the jwst near infrared camera on just one field to form the “jades origins field.” with the use of filters designed to better isolate the earliest galaxies, confidence grew that jades gs z14 0 was indeed very distant. “we just couldn’t see any plausible way to explain this galaxy as being merely a neighbour of the more nearby galaxy,” said dr kevin hainline, research professor at the university of arizona. fortunately, the galaxy happened to fall in a region where the team had conducted ultra deep imaging with the jwst mid infrared instrument. the galaxy was bright enough to be detected in 7.7 micron light, with a higher intensity than extrapolation from lower wavelengths would predict. “we are seeing extra emission from hydrogen and possibly even oxygen atoms, as is common in star forming galaxies, but here shifted out to an unprecedented wavelength,” said jakob helton, graduate student at the university of arizona and lead author of a second paper on this finding. these combined imaging results convinced the team to include the galaxy in what was planned to be the capstone observation of jades, a 75 hour campaign to conduct spectroscopy on faint early galaxies. the spectroscopy confirmed their hopes that jades gs z14 0 was indeed a record breaking galaxy and that the fainter candidate, jades gs z14 1, was nearly as far away. beyond the confirmation of distance, the spectroscopy allows further insight into the properties of the two galaxies. being comparatively bright, jades gs z14 0 will permit detailed study. “we could have detected this galaxy even if it were 10 times fainter, which means that we could see other examples yet earlier in the universe probably into the first 200 million years,” says brant robertson, professor of astronomy and astrophysics at the university of california santa cruz, and lead author of a third paper on the team’s study of the evolution of this early population of galaxies. “the early universe has so much more to offer.” reference carniani, s et al. a shining cosmic dawn: spectroscopic confirmation of two luminous galaxies at z∼14. arxiv:2405.18485 [astro ph.ga] the text in this work is licensed under

introducing the all new astronomy.com forum! become a part of our community! >> visit now a galaxy named hd1 has been crowned the new farthest object in the cosmos. located some 13.5 billion light years away, hd1 existed only about 330 million years after the big bang. and the far flung galaxy may be harboring another surprise, too   either population iii stars, the first stars born in the cosmos, or the earliest supermassive black hole ever found. the findings are presented in two papers, released today (april 7) in the astrophysical journal and the monthly notices of the royal astronomical society letters (mnras). hd1 is extremely bright in ultraviolet light, which is normally evidence that a galaxy is producing stars at a high rate. but researchers quickly realized that even if hd1 was a starburst galaxy, it would be creating over 100 stars a year. “this is at least 10 times higher than what we expect for these galaxies,” said fabio pacucci, lead author of the mnras study, co author in the discovery paper in the astrophysical journal, in a news release. so the team turned to other possibilities that might explain hd1’s surplus of ultraviolet light. one possible explanation for hd1’s ultraviolet radiance is that the stars the galaxy is producing are different from the mundane stars produced in modern galaxies. today, stars are made from recycled material ejected from previous generations of stars. so, every star has some heavier elements, even if just a sprinkle. but in the very early universe, after the big bang, primordial gas consisted entirely of hydrogen, helium, and a sampling of lithium and beryllium. from these elements, the first stars were born. known as population iii stars, they were more massive, more luminous, and hotter than today’s stars. they also perfected the mantra of live fast, die young, burning out within only a few million years. the only problem: population iii stars are hypothetical as their quick lives means no direct evidence of them has ever been spotted. but the recent discovery of the earliest star, earendel, may prove fruitful for population iii hunters   if follow up studies find the star’s composition to be entirely hydrogen and helium. in the meantime, while population iii stars would easily explain hd1’s brightness in the ultraviolet wavelength, they aren’t the only possibility. alternatively, a supermassive black hole might explain the galaxy’s ultraviolet brightness. if that’s the case, the supermassive black hole would become the earliest known, breaking the previous record by some 500 million years. supermassive black holes are believed to reside in the hearts of most galaxies, but understanding how these monsters grew so big so quickly in the early universe remains a conundrum for scientists. physics tells us that black holes need time to gobble up enough material to grow to supermassive proportions, meaning that scientists didn’t expect to see them so early in the cosmic timeline. but in 2017, astronomers began finding these monsters within the universe’s earliest galaxies. disks of material surrounded the black holes, and the infalling matter shone so brightly the galaxies, despite their extreme distances, can still be seen today. it is the high energy photons from that infalling material, which gets violently swirled around the black hole, that might be causing hd1’s ultraviolet brightness. “forming a few hundred million years after the big bang, a black hole in hd1 must have grown out of a massive seed at an unprecedented rate,” explains mnras co author avi loeb. such an early black hole may not answer the question of how these objects grew so big so quickly, but it would narrow down how soon they appeared in the early universe. jwst up to bat to make this distant discovery, the team spent more than 1,200 hours observing with the subaru telescope, vista telescope, uk infrared telescope, and spitzer space telescope. to verify hd1’s distance, the team plans to observe the galaxy again, this time with nasa’s powerful james webb space telescope. capable of peering back to the first luminous glows that emerged after the big bang, jwst will also be able to settle which theory explains hd1’s ultraviolet shine. and, perhaps, find even more distant galaxies in the earliest moments of the cosmos. get newsletters, updates and special offers via email from astronomy.com!

4 min read nasa’s james webb space telescope has followed up on observations by the hubble space telescope of the farthest star ever detected in the very distant universe, within the first billion years after the big bang. nasa’s james webb space telescope has followed up on observations by the hubble space telescope of the farthest star ever detected in the very distant universe, within the first billion years after the big bang. webb’s nircam (near infrared camera) instrument reveals the star to be a massive b type star more than twice as hot as our sun, and about a million times more luminous. the star, which the research team has dubbed earendel, is located in the sunrise arc galaxy and is detectable only due to the combined power of human technology and nature via an effect called gravitational lensing. both hubble and webb were able to detect earendel due to its lucky alignment behind a wrinkle in space time created by the massive galaxy cluster whl0137 08. the galaxy cluster, located between us and earendel, is so massive that it warps the fabric of space itself, which produces a magnifying effect, allowing astronomers to look through the cluster like a magnifying glass. while other features in the galaxy appear multiple times due to the gravitational lensing, earendel only appears as a single point of light even in webb’s high resolution infrared imaging. based on this, astronomers determine the object is magnified by a factor of at least 4,000, and thus is extremely small   the most distant star ever detected, observed 1 billion years after the big bang. the previous record holder for the most distant star was detected by hubble and observed around 4 billion years after the big bang. another research team using webb recently identified a gravitationally lensed star they nicknamed quyllur, a red giant star observed 3 billion years after the big bang. stars as massive as earendel often have companions. astronomers did not expect webb to reveal any companions of earendel since they would be so close together and indistinguishable on the sky. however, based solely on the colors of earendel, astronomers think they see hints of a cooler, redder companion star. this light has been stretched by the expansion of the universe to wavelengths longer than hubble’s instruments can detect, and so was only detectable with webb. webb’s nircam also shows other notable details in the sunrise arc, which is the most highly magnified galaxy yet detected in the universe’s first billion years. features include both young star forming regions and older established star clusters as small as 10 light years across. on either side of the wrinkle of maximum magnification, which runs right through earendel, these features are mirrored by the distortion of the gravitational lens. the region forming stars appears elongated, and is estimated to be less than 5 million years old. smaller dots on either side of earendel are two images of one older, more established star cluster, estimated to be at least 10 million years old. astronomers determined this star cluster is gravitationally bound and likely to persist until the present day. this shows us how the globular clusters in our own milky way might have looked when they formed 13 billion years ago. astronomers are currently analyzing data from webb’s nirspec (near infrared spectrograph) instrument observations of the sunrise arc galaxy and earendel, which will provide precise composition and distance measurements for the galaxy. since hubble’s discovery of earendel, webb has detected other very distant stars using this technique, though none quite as far as earendel. the discoveries have opened a new realm of the universe to stellar physics, and new subject matter to scientists studying the early universe, where once galaxies were the smallest detectable cosmic objects. the research team has cautious hope that this could be a step toward the eventual detection of one of the very first generation of stars, composed only of the raw ingredients of the universe created in the big bang   hydrogen and helium. the james webb space telescope is the world’s premier space science observatory. webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. webb is an international program led by nasa with its partners, esa (european space agency) and the canadian space agency. media contacts: laura betznasa’s goddard space flight center, greenbelt, md.laura.e.betz@nasa.gov christine pulliam / leah ramsayspace telescope science institute, baltimore, md.cpulliam@stsci.edu / lramsay@stsci.edu nasa explores the unknown in air and space, innovates for the benefit of humanity, and inspires the world through discovery.
out there astronomers have found the earliest and most distant galaxy yet. the newly discovered galaxy, known as jades gs z14 0, emanates light that is 13.5 billion years old.credit... nasa, esa, csa, stsci, b. robertson (uc santa cruz), b. johnson (cfa), s. tacchella (cambridge), p. cargile (cfa) supported by by dennis overbye since the james webb space telescope began operating two years ago, astronomers have been using it to leapfrog one another millions of years into the past, back toward the moment they call cosmic dawn, when the first stars and galaxies were formed. last month, an international team doing research as the jwst advanced deep extragalactic survey, or jades, said it had identified the earliest, most distant galaxy yet found   a banana shaped blob of color measuring 1,600 light years across. it was already shining with intense starlight when the universe was in its relative infancy, at only 290 million years old, the astronomers said. the new galaxy, known as jades gs z14 0, is one of a string of webb discoveries, including early galaxies and black holes, that challenge conventional models of how the first stars and galaxies formed. “this discovery proves that luminous galaxies were already in place 300 million years after the big bang and are more common than what was expected,” the researchers wrote in a paper posted to an online physics archive. “galaxy formation models will need to address the existence of such large and luminous galaxies so early in cosmic history,” said the authors, who were led by stefano carniani, a professor at the university scuola normale superiore in pisa, italy. the galaxy was first spotted during a deep space survey with the webb’s near infrared camera, one of the telescope’s workhorse instruments. within a patch of southern sky known as the jades origin field, which is about a quarter of the size of a full moon, scientists found 11 galaxies that seemed to date from when the universe was less than 400 million years old   far more than they had expected.

 no offers found the most distant jades gs z14 0 is a massive and bright galactic record breaker that existed just 300 million years after the big bang. when you purchase through links on our site, we may earn an affiliate commission. here’s how it works. the james webb space telescope (jwst) has discovered not one but two of the earliest and most distant galaxies ever seen, continuing to break the records it previously set. the furthest galaxy, jades gs z14 0, is seen as it was around 300 million years after the big bang, existing at least 100 million years earlier than the previous record holder. that means that the light the jwst saw from this primordial galaxy has been traveling for 13.5 billion years on its way to reach us. jades gs z14 0 isn't alone, either. it was discovered along with another galaxy, jades gs z14 1, that is almost as far away and takes second place in the ranking of the earliest galaxies ever seen by humanity. related: james webb space telescope spots 3 of our universe's earliest galaxies the announcement of the discoveries, made in oct. 2023 and jan. 2024, are the latest developments in the ongoing investigation of cosmic dawn that the $10 billion telescope has facilitated as part of the jwst advanced deep extragalactic survey (jades) program. jades aims to provide vital insights into the ways in which the stars, gas, and black holes were evolving in primordial galaxies when the 13.8 billion year old universe was very young.
