Earendel was first discovered by the Hubble Space Telescope last year.
Webb is 100 times more powerful than Hubble, though, and it captured previously unseen colors of the distant star.
Those colors reveal that being the farthest star we've ever detected does not make Earendel lonely — scientists believe it has a companion star beside it.
Stars as massive as Earendel do typically have companions, but Hubble was unable to detect one for Earendel.
Thanks to the Webb Telescope's powerful infrared vision, though, scientists believe they can see, for the first time, a "cooler, redder companion star" beside Earendel.
