Oldest 'dead' galaxy seen in one of the deepest views of universe

Scientists have spotted the oldest "dead" galaxy ever observed using James Webb Space Telescope in one of its deepest view of the distant universe. The galaxy, named JADES-GS-z7-01-QU, existed when the universe was about 700 million years into its current age of 13.8 billion years. An unexplained phenomenon made the galaxy suddenly halt star formation.
