Astronomers using the James Webb Space Telescope have discovered the oldest"dead" galaxy ever seen — but the cosmic corpse has left scientists puzzled as it defies explanation by our current knowledge of the early cosmos.
The galaxy, named JADES-GS-z7-01-QU and described in a paper published Wednesday in the journal Nature, provides astronomers with a peek into the elusive underpinnings of galaxy evolution in a primordial universe, including why galaxies stop forming new stars and whether forces driving their starbursts alter across epochs.
