New research suggests that galaxies with quasars at their active hearts are seven times more likely to harbor elusive ...

The team used the Multi-Unit Spectroscopic Explorer (MUSE) on the European Southern Observatory’s Very Large Telescope in ...

Quasars are the blazing centers of active galaxies and are powered by a supermassive black hole feeding on humungous quantities of gas. When you purchase through links on our site, we may earn an ...

Quasars are immensely bright. From the central point in a galaxy, they emit as much energy as thousands of giant galaxies from a region as tiny as the Solar System.

By almost all the properties that can be deduced from the spectrum, J1120+0641 is no different from quasars at later times. “Overall, the new observations only add to the mystery: Early quasars were ...

Also, quasars are some of the brightest objects in the universe, and unlike supernovae can be studied for much longer time scales. Unfortunately, quasars emit different amounts of light in all ...

This illustration depicts two quasars in the process of merging. Using both the Gemini North telescope and the Subaru Telescope, a team of astronomers have discovered a pair of merging quasars ...

Observing quasars over time allowed a team of astronomers to see how the universe seemed to speed up as it aged. The results of the study published Monday in the journal Nature Astronomy.

Quasars represent some of the most luminous and energetic phenomena in the universe. These distant powerhouses are driven by supermassive black holes—colossal gravitational engines with masses ...
