Pasadena, CA-- New work from an international team of astronomers including Carnegie's Gregory Walth improves our understanding of the most-distant known astrophysical object-- GN-z11, a galaxy 13.4 billion light-years from Earth. Formed 400 million years after the Big Bang, GN-z11 was previous...

The farthest galaxy in the universe A team of astronomers used the Keck I telescope to measure the distance to an ancient galaxy. They deduced the target galaxy GN-z11 is not only the oldest galaxy but also the most distant. It's so distant it defines the very boundary of the observable universe itself. The team hopes this study can shed light on a period of cosmological history when the universe was only a few hundred million years old. We've all asked ourselves the big questions at times: "How big is the universe?" or "How and when did galaxies form?" Astronomers take these questions very s...
