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.

Levay Image description: The image is split in half vertically to create two images. In the left image, a black background is scattered with hundreds of small galaxies of different shapes, ranging in color from white to yellow to red. Some galaxies, mostly the redder galaxies, are distorted, appearing to be stretched out or mirror imaged. Just a little bit above the center, there is a bright source of light, a star, with 8 bright diffraction spikes extending out from it. Below the star are several noticeably fuzzy white galaxies that resemble cotton balls – these are part of a galaxy cluster. To the lower right of the star is a long, red, thin line stretching from one o’clock to 7 o’clock, outlined in a white inset box. This is the Sunrise Arc. The right image is a close-up of that long red line. There are several bright dots, some thicker than others, along this line, with one labeled as Earendel. |
