Astronomers have discovered the most distant individual star ever spotted, located nearly 13 billion light years away, in a stunning breakthrough that was achieved using NASA’s Hubble Space Telescope, reports a new study. 

Because looking across space is also looking back in time, Hubble saw this star as it was when the universe was only about 900 million years old. The star, nicknamed Earendel after the Old English word for “morning star” or “rising light,” is dramatically farther than the previous record-holder, a star named Icarus, also discovered by Hubble, when the universe was already four billion years old.
