what are some of his discoveries?
He identified Cepheid variables in several spiral nebulae, including the Andromeda Nebula and Triangulum. His observations, made in 1924, proved conclusively that these nebulae were much too distant to be part of the Milky Way.
Edwin Hubble
Edwin Hubble's arrival at Mount Wilson Observatory, California in 1919 coincided roughly with the completion of the Hooker Telescope, then the world's largest. At that time, the prevailing view of the cosmos was that the universe consisted entirely of the Milky Way Galaxy. Using the Hooker Telescope at Mt. Wilson, Hubble identified Cepheid variables (a kind of star that is used as a means to determine the distance from the galaxy – see also standard candle) in several spiral nebulae, including the Andromeda Nebula and Triangulum. His observations, made in 1924, proved conclusively that these nebulae were much too distant to be part of the Milky Way and were, in fact, entire galaxies outside our own, suspected by researchers at least as early as 1755 when Immanuel Kant's General History of Nature and Theory of the Heavens appeared. This idea had been opposed by many in the astronomy establishment of the time, in particular by Harvard University-based Harlow Shapley. Despite the oppositi
when was the hubble space telescope launched and when will it stop operating It was launched into low Earth orbit on April 24, 1990 and remains in operation. what are some of its features? It carried five scientific instruments: the Wide Field and Planetary Camera (WF/PC), Goddard High Resolution Spectrograph (GHRS), High Speed Photometer (HSP), Faint Object Camera (FOC) and the Faint Object Spectrograph (FOS). WF/PC was a high-resolution imaging device primarily intended for optical observations. who designed it? Marshall Space Flight Center (MSFC) is it named after someone? Yes - MSFC is named in honor of General of the Army George Marshall. where is it located? Huntsville, Alabama does it have a program related to constellation? Between 2004 and early 2010, the Constellation Program was a major NASA activity. MSFC was responsible for the propulsion of the proposed Ares I and Ares V heavy-lift vehicles. what other researches do they carry out? Teams at MSFC manage NASA's programs for exploring the Sun, the Moon, the planets, and other bodies throughout our solar system.MSFC also develops systems for monitoring the Earth's climate and weather patterns. when was the above mentioned space agency established? UNANSWERABLE was the aforementioned telescope named after someone? Yes - it is named after astronomer Edwin Hubble
