Astronomers identify 13.1-billion-year-old galaxy
May 8 , 2015
Astronomers have identified a galaxy that formed 13.1 billion years ago, making it the earliest galaxy ever seen by humans.
The universe, according to the big bang theory, is 13.8 billion years old. EGS-zs8-1, as the galaxy is called, is believed to be 30 billion light years away from our planet, the astronomers from the University of California Santa Cruz and Yale University say.
The galaxy, as seen in its infancy, had already built over "15% of the mass” of the present Milky Way, researcher Pascal Oesch said in a statement.
