Summary

Story summary

Astronomers captured a direct view of star-driven winds quenching a massive galaxy a billion years after the Big Bang.
Observations of CRISTAL-02 showed a gas outflow of about 1.5 billion solar masses moving at several hundred miles per second, stripping 500 solar masses of gas each year—twenty times typical loss.
Forming 260 solar-mass stars per year, CRISTAL-02 could run out of star-forming gas in under 100 million years if the outflow persists.
