New Research: When Galaxies Collide, Black Holes Take Over

A groundbreaking new study published in Nature reveals what happens when two massive galaxies crash into each other nearly 11 billion years ago. One of them hosts a blazing quasar — a supermassive black hole devouring gas and shining incredibly bright.

What’s truly fascinating? The quasar’s powerful radiation is disrupting the gas in the other galaxy, breaking it into tiny, dense clumps that are too small to form new stars.

This rare discovery shows that galaxy mergers can ignite quasars, and those same quasars can shut down star formation, changing the future of entire galaxies.
