Earendel: JWST Suggests the Most Distant Star May Be a Star Cluster

The most distant object in the universe ever discovered, Earendel, might not in fact be a lone star as scientists initially assumed. It was spotted on 2022 by the Hubble Space Telescope and appeared to have evolved just 900 million years after the Big Bang, at a time when the universe was a mere infant. But fresh data from the newly launched James Webb Space Telescope (JWST) indicate that Earendel may not be a massive solitary star, but rather a small group of them — a star cluster. How We Can See It As per Live Science report , Earendel is located in the Etendeka galaxy of the Sunrise Arc, some 12.9 billion light-years from Earth. We can see it thanks to the effect of a special one known as gravitational lensing. The lensing occurs when a massive galaxy cluster warps and amplifies the light from objects situated much farther away. In this one, Earendel's light was 4,000 times as bright, shining in a way that astronomers would be able to catch it. Such rare alignments lead scientis...
