Webb sees most distant star ever observed

The James Webb Space Telescope has imaged the most distant star ever discovered, which is 8.5 million parsecs away. The star was first identified by the Hubble Space Telescope earlier this year. WHL0137-LS — or ‘Earendel’, meaning ‘morning star’ in old English — is thought to have formed just 900 million years after the Big Bang. It is visible thanks to gravitational lensing: the massive Sunrise Arc galaxy cluster in its foreground warps spacetime so much that the star is magnified thousands of times.
