Astronomers just discovered the oldest and most distant galaxy ever

As astronomers look deep into space, they also see far back in time. Now, astronomers at the University of Tokyo may have found the oldest, most distant galaxy ever seen. These observations come close to revealing conditions in the Universe when the first observable light spread throughout the Cosmos.

The ancient galaxy GN-z11 likely formed just 420 million years after the Big Bang, when the Universe was just three percent as old as it is today. Such an age would place this family of stars near the edge of the observable Universe. This galaxy formed at the dawn of the era of reionization when light first filled the Cosmos.
