A massive galaxy in the early universe, CRISTAL-02, is blasting away cold gas while forming new stars, a process that may explain why many big galaxies died young.

Why

CRISTAL-02 offers a simpler answer to the puzzle of massive, quiescent galaxies existing just 1 billion years after the Big Bang by showing merging galaxies create powerful winds that sweep away star-forming gas.

The Frontline Impact

How this affects you

This research provides a concrete mechanism for astronomers to understand how star formation ceased in some of the universe's earliest massive galaxies, suggesting that strong stellar feedback, especially supernova explosions during galaxy mergers, is a key factor rather than more speculative causes.
