Astronomers spot 'dead galaxy' that has stopped forming stars
Astronomers have discovered the most distant and massive 'dead galaxy', called RUBIES-UDS-QG-z7, using the James Webb Space Telescope (JWST). A galaxy that stops creating new stars is categorised as a 'dead galaxy'. The oldest known 'dead galaxy', JADES-GS-z7-01-QU, was spotted in March last year, which stopped producing stars when the universe was just 700 million years old.
