Brainiacs at UC Irvine have discovered a cluster of galaxies in the early stages of formation, pegging the age at a whopping 11.4 billion years old, which stands as the new record holder.
“When you observe objects this far away, you are actually seeing the universe as it was a very long time ago,” said Jeff Cooke, a McCue Postdoctoral Fellow in physics and astronomy at UCI and lead author of this study. “It is as if a timeline is just sitting out there in front of you. These galaxies represent what the universe looked like well before the Earth existed.”
“Our finding suggests that this is a monster structure being born in a very bright, catastrophic event with a lot of gas and matter collapsing at once,” Bullock said. “We are not just seeing one solitary galaxy. We are seeing a bunch of bright galaxies coming together at the dawn of structure formation in the universe.”
