| Description |
English: The light of Earendel, our most beloved star ⭐
Discovered by Hubble, Earendel is the farthest star ever detected. It existed in the first billion years after the big bang! The James Webb Space Telescope now shows it to be a massive B-type star, more than twice as hot as our Sun and about a million times more luminous. It’s only detectable thanks to its alignment with a galaxy cluster between Earendel and us. The cluster’s gravity bends light, magnifying what is behind it — in the case of a star-sized object like Earendel, by a factor of at least 4000. Based on the colors of the light of Earendel, astronomers think it may have a cooler companion star. Webb is also able to see other details in Earendel’s host galaxy, the Sunrise Arc — the most highly magnified galaxy yet detected in the universe’s first billion years. Those features include both young star-forming regions and older, established star clusters as small as 10 light-years across. Because Webb is so sensitive, it has spotted other very distant stars, though not quite so distant as Earendel. Astronomers have cautious hope that the very first generation of stars in the universe may yet be detectable. Learn more: www.nasa.gov/feature/goddard/2023/webb-reveals-colors-of-... This image: This image from NASA’s James Webb Space Telescope of a massive galaxy cluster called WHL0137-08 contains the most strongly magnified galaxy known in the universe’s first billion years: the Sunrise Arc, and within that galaxy, the most distant star ever detected. In this image, the Sunrise Arc appears as a red streak just below the diffraction spike at the 5 o’clock position.
