The Hubble Space Telescope observes the most distant single star ever. The star, named Earendel by astronomers, is 28 billion light-years away. It is the farthest detection of a star, dating back 900 million years after the Big Bang. This discovery surpasses Hubble's record from 2018, when it discovered a star that existed when the universe was roughly four billion years old.

Space telescope observations indicate that the supernova RCW 86, first seen by Chinese astronomers in 185 AD, expanded at an unprecedented rate due to the formation of a vacuum-like "cavity" around it in the early stages of the death of its star. The supernova's rapid expansion had previously been one of astronomy's most enduring mysteries.
