Astronomers using the Hubble Space Telescope spot the farthest star ever

Cape Canaveral, Florida.

Astronomers have discovered the most distant star yet, a super-hot, super-bright giant that formed nearly 13 billion years ago at the dawn of the cosmos.

But this luminous blue star is long gone, so massive that it almost certainly exploded to pieces only a few million years after it emerged. Its rapid disappearance makes it all the more incredible that an international team has spotted it with observations from the Hubble Space Telescope. The light emitted by distant stars takes eons to reach us.

“We’re seeing the star as it was about 12.8 billion years ago, which puts it about 900 million years after the Big Bang,” said astronomer Brian Welch, a doctoral student at Johns Hopkins University and lead author of the study that appears. in Wednesday’s edition. Nature magazine.
