In Pictures: Fabulous space photos from NASA’s Hubble telescope

NASA’s Hubble telescope is celebrating 22 years as a space discovery icon

In 2011 astronomers said they used the Hubble to spot a galaxy whose light traveled 13.2 billion years to reach Earth, about 150 million years longer than the previous record holder. According to NASA the tiny, dim object is a compact galaxy of blue stars that existed 480 million years after the big bang. More than 100 such mini-galaxies would be needed to make up our Milky Way. The research offered surprising evidence that the rate of star birth in the early universe grew dramatically, increasing by about a factor of 10 from 480 million years to 650 million years after the big bang, NASA stated.
