This radiation now impacts the neighboring galaxy, disrupting its star-forming regions. The quasar’s radiation breaks molecular clouds into small, dense clumps that are too tiny to form new stars.

One galaxy uses a quasar like a cosmic weapon, blasting its opponent and halting star formation—an epic deep-space duel seen ...

Credit: ESO / M. Kornmesser illustration When astronomer Maarten Schmidt found the first quasar in 1963, it looked like a star, though it was much too far away for that to have been the source.

According to researchers, the quasar’s radiation strips away much of the gas and dust in the companion galaxy, leaving behind only small, dense clumps that are likely too compact to kick off star ...

In a rare cosmic spectacle, astronomers have observed two galaxies engaged in a high-speed collision, approximately 11 billion light-years away. One g ...

Astronomers witnessed two galaxies engaged in an intense deep-space battle for the first time. Watch the “cosmic joust” in action.

The moment one galaxy spears another with a powerful beam of radiation shooting from its central black hole has been spotted ...

By combining data from the Subaru Telescope and James Webb Space Telescope, researchers have discovered distant quasars that ...

Back in the 19 nineties, astronomers started to see growing evidence that the universe was accelerating. We thought gravity would slow things down so I could throw up *** ball. Gravity is gonna ...
