Why in news
The James Webb Space Telescope (JWST) recorded the earliest known supernova, providing evidence on the short lifespans of the first stars and their role in galaxy formation.
Background
The supernova occurred in a young galaxy during the first billion years after the Big Bang. It was detected through subtle light variations over time, revealing the creation of heavy elements crucial for planet formation.
Facts for Prelims
