Astronomers have glimpsed a galaxy located an unprecedented 13.5 billion light-years from Earth, just 330 million years after the Big Bang, making it by far the most distant object ever seen by humans, according to a pair of new studies.

The stunning galaxy, called HD1, is 100 million light-years farther than the next most distant object ever spotted, and emits a bright ultraviolet glow that currently defies explanation. It was discovered by Yuichi Harikane, an assistant professor at the University of Tokyo, who is the lead author of a study that reports the breakthrough in The Astrophysical Journal on Thursday.
