"Webb Telescope Discovers Earliest 'Dead' Galaxy in Distant Universe"

The James Webb Space Telescope has discovered a galaxy that ceased star formation when the universe was only 5% of its current age, making it the earliest-known "dead" galaxy by about 500 million years. This small galaxy experienced a rapid burst of star formation followed by a sudden stop, leaving it like a stellar graveyard. Scientists are investigating potential causes such as the influence of a supermassive black hole or energy feedback from newly formed stars. The discovery sheds light on the early universe and raises questions about the fate of such galaxies.
