age of space
Noun. 1. space age-the age beginning with the first space travel; from 1957 to the present. time-an indefinite period (usually marked by specific attributes or activities); he waited a long time; the time of year for planting; he was a great actor in his time. Translations. n → era spaziale. Beginning: The Space Age is thought to have officially begun on October 4th, 1957, with the launch of Sputnik 1 by the Soviet Union – the first artificial satellite to be launched into orbit. Age may only be a number, but when it comes to the age of the universe, it's a pretty important one. According to research, the universe is approximately 13.8 billion years old. But above all, ongoing space exploration, the hallmark of the “Space Age”, is likely to transform humanity from a terrestrial race into an interplanetary (or even interstellar) one! Universe Today also has articles on space exploration and space age archaeology. space age. n. The period after 1957, the year in which a spacecraft was first placed in orbit around Earth, marking the beginning of space exploration. space′-age′ adj. In 2012, WMAP estimated the age of the universe to be 13.772 billion years, with an uncertainty of 59 million years. In 2013, Planck measured the age of the universe at 13.82 billion years. Both of these fall within the lower limit of 11 billion years independently derived from the globular clusters, and both have smaller uncertainties than that number.

A 2013 map of the background radiation left over from the Big Bang, taken by the ESA's Planck spacecraft, captured the oldest light in the universe. This information helps astronomers determine the age of the universe. In the case of Vostok, this consisted of developing a space capsule that could be launched aboard an expendable carrier rocket. Along with numerous unmanned tests, and a few using dogs, six Soviet pilots were selected by 1960 to be the first men to go into space. The universe cannot be younger than the objects contained inside of it. By determining the ages of the oldest stars, scientists are able to put a limit on the age. The life cycle of a star is based on its mass. More massive stars burn faster than their lower-mass siblings. This was what is popularly known as the “Space Age”, an era that was born of the advent of nuclear power, advances in rocketry, and the desire to be the first to put men into space and on the Moon.
