Astronomers observe rare early galaxy in death throes

In the early universe, when galaxies were expected to be young and generative, astronomers have observed one already falling silent — its star formation ceasing in the cosmos's first billion years. This rare detection challenges long-held assumptions about the pace of galactic decline, suggesting that the forces which extinguish galaxies may act faster and more ruthlessly than our models have allowed. It is a reminder that even in the universe's youth, endings were already underway.
