Hubble Sees Most Distant Star Ever, 28 Billion Light-Years Away

The Hubble Space Telescope has glimpsed the most distant single star it's ever observed, glimmering 28 billion light-years away. And the star could be between 50 to 500 times more massive than our sun, and millions of times brighter. From a report: It's the farthest detection of a star yet, from 900 million years after the big bang. Astronomers have nicknamed the star Earendel, derived from an Old English words that means 'morning star' or 'rising light.' A study detailing the findings published Wednesday in the journal Nature. This observation breaks the record set by Hubble in 2018 when it observed a star that existed when the universe was around four billion years old. Earendel is so distant that the starlight has taken 12.9 billion years to reach us. This observation of Earendel could help astronomers to investigate the early years of the universe.

'As we peer into the cosmos, we also look back in time, so these extreme high-resolution observations allow us to understand the building blocks of some of the very first galaxies,' said study coauthor Victoria Strait, a postdoctoral research at the Cosmic Dawn Center in Copenhagen, in a statement. 'When the light that we see from Earendel was emitted, the Universe was less than a billion years old; only 6% of its current age. At that time it was 4 billion lightyears away from the proto-Milky Way, but during the almost 13 billion years it took the light to reach us, the Universe has expanded so that it is now a staggering 28 billion lightyears away.'
