In March 2022, the Hubble Space Telescope detected the most distant star ever seen in the cosmos.
Now, the James Webb Space Telescope (JWST) has captured an even more detailed glimpse of this ancient celestial body, revealing it to be a massive B-type star that's more than twice as hot as the sun and roughly a million times brighter. The star is known as WHL0137-LS — nicknamed Earendel — and resides in the Sunrise Arc galaxy. Light we detect now from Earendel began its journey from the star 12.9 billion years ago, which means the star began emitting its rays less than a billion years after the Big Bang, according to Live Science's sister site Space.com. Because every point in the known universe has been expanding like a cosmic balloon since then, Earendel now lies 28 billion light-years from Earth.
