JWST Turns its Gaze on the Farthest Known Star: Earendel
A few years ago, astronomers announced the discovery of the most distant star ever seen. Nicknamed "Earendel," it was found as part of a gravitational lens seen by the Hubble Space Telescope. Now astronomers have used the mighty JWST to observe the star with unprecedented clarity, studying the chemical composition of a star seen less than a billion years after the Big Bang. The image is so sensitive astronomers think they might have even found a dimmer companion star.
