Galaxy-killing wind discovered in the early universe

4 hours ago

Astronomers discovered a 'galaxy-killing wind' powered by cosmic collisions, which could explain the abundance of massive 'dead' galaxies in the early universe.
Using JWST and ALMA, researchers observed galaxy CRISTAL-02, which is forming stars rapidly and ejecting cold gas via powerful winds, potentially leading to its death in under 50 million years.
The study suggests that nearly half of early massive galaxies interact with others, indicating that collisions and subsequent star-formation bursts followed by winds are a widespread phenomenon.
This theory offers a simpler explanation for why galaxies in the early universe lived fast and died young, solving a mystery highlighted by JWST observations.
