Astronomers pushed the farthest record of the measured bodies in the universe to 13.1 billion light years. The light from EGS-zs8-1 comes from the era when the universe was just 5 percent of its current age.   

The galaxy was first identified on Hubble and Spitzer space telescopes for its distinctive colors and brightness. The international team led by Yale and California-Santa Cruz universities determined its exact distance by using an instrument on a 10-meter telescope in Hawaii.

The distance and the age is synonyms in astronomy. The distance of the bodies also refer to their age since the images show us how they looked like years ago.

“It has already built more than 15% of the mass of our own Milky Way today,” said Pascal Oesch, a Yale astronomer and lead author of a study.

“But it had only 670 million years to do so. The universe was still very young then.”
