Astronomers have spotted seven galaxies that existed just a few hundred million years after the universe's birth, including one that may be the oldest found to date.
The potential record-holding galaxy, known as UDFj-39546284, likely existed when the universe was just 380 million years old, researchers said, and may be the farthest galaxy ever seen. The other six distant galaxies all formed within 600 million years of the Big Bang, which created our universe 13.7 billion years ago.
UDFj-39546284 was detected previously, and researchers had thought it formed just 500 million years or so after the Big Bang. The new observations, made using NASA's Hubble Space Telescope, push its probable formation time back even further.
The seven galaxies constitute the first reliable census of the epoch from 400 million to 600 million years after the universe's birth, researchers said. This census detects a steady increase in galaxies over this period, suggesting that the formation of the first stars and galaxies — the so-called "cosmic dawn" — happened gradually rather than suddenly.
