Scientists recently went where no one has gone before, at least in a metaphorical sense, when they discovered what they believe is the farthest galaxy from our own, and also the oldest known galaxy ever found. An international team of astronomers led by Yale and the University of California Santa Cruz recently captured a photograph of an “exceptionally luminous galaxy” located roughly 13 billion years in the past, dating back to when the universe was only about five percent of its present age. They made the discovery using the MOSFIRE instrument at the W.M. Keck Observatory telescope, a powerful device about 10 meters across.
