JADES-GS-z7-01-QU (also known as JADES-GS+53.15508-27.80178)[1] is a Lyman-break galaxy, first identified in 2010,[2] located in the constellation Fornax. It formed around 700 million years after the birth of the universe, after which it suddenly stopped creating new stars.[3] It experienced rapid star formation around 80 million years before the epoch of observation, lasting for at least 30 million years, before ending around 10-20 million years before the epoch of observation. It is the oldest and most distant "dead" galaxy so far discovered.[2][4]
