A quasar is a black hole that draws in matter from the surrounding space. Its strong gravitational field imposes a huge kinetic energy on this matter, causing it to radiate across a wide range of ...

According to a new study, extremely red quasars — more than any other class of quasars — play a key role in regulating star formation in their host galaxies. Star formation in a galaxy occurs when ...

Galaxies formed and grew billions of years ago by accumulating gas from their surroundings, or colliding and merging with other young galaxies. These early stages of galaxy assembly are believed to be ...

A distant galaxy has been caught in the act of shutting down. The galaxy, called CQ 4479, is still forming plenty of new stars. But it also has an actively feeding supermassive black hole at its ...

This image, taken with the Atacama Large Millimeter/submillimeter Array (ALMA), shows the molecular gas content of two galaxies involved in a cosmic collision. The one on the right hosts a quasar –– a ...

The most luminous galaxy in the universe is a roilingly turbulent quasar in the process of ejecting all its star-forming gas. Michelle Starr is CNET's science editor, and she hopes to get you as ...

Which came first: supermassive black holes, or the galaxies that orbit them? Recent observations of a distant quasar with no apparent host galaxy and a nearby companion galaxy suggest that it is ...

Research led by Johns Hopkins University scientists has found new, persuasive evidence that could help solve a long-standing mystery in astrophysics: why did the pace of star formation in the universe ...

CAPE CANAVERAL, Fla. (AP) — Astronomers have discovered what may be the brightest object in the universe, a quasar with a black hole at its heart growing so fast that it swallows the equivalent of a ...

The most energetic objects in the universe may be stopping the biggest galaxies from growing bigger. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it ...
