(Phys.org) —Like our Milky Way, every known large galaxy has at its center a supermassive black hole, some of which are surrounded by a super-bright disk of hot gas called a quasar—but now a ...
Astronomers using the Hubble Space Telescope and other observatories have discovered a pair of gravitationally-bound quasars inside two merging galaxies. Quasars are active and luminous types of ...
By combining data from the Subaru Telescope and James Webb Space Telescope, researchers have discovered distant quasars that are obscured by dust but which may shed light on Little Red Dots.
In a Q&A, astrophysicist Chiara Mingarelli explains how black hole mergers and quasars are helping lay the groundwork for detecting a network of gravitational waves.
A team of astrophysicists say quasars, some of the most brilliant phenomena in the universe, are likely caused by collisions between galaxies. Quasars are a type of active galactic nuclei; they ...
Found at the center of large, early galaxies, quasars are so luminous they can outshine the sun as much as 27 trillion times over.
Ancient quasars seen by the James Webb Space Telescope technically shouldn’t exist, but one rare type of dark matter could make sense of that. Ultra-self-interacting dark matter clumped into ...

Quasars don't last long—so how do they get so massive? - MSNQuasars 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 ...
Quasars are a type of active galactic nucleus (AGN), meaning the galaxy's core exhibits much higher brightness than usual. A quasar shines so brightly because they are home to supermassive black ...
Maarten Schmidt, the Dutch-born American astronomer who explained the mysterious heavenly bodies known as quasars and in so doing helped create the modern picture of the universe, its structure ...
This distant galaxy was observed in a 2020 study that discovered a number of quasars with newly formed jets. A quasar is a type of active galactic nucleus—a galaxy hosting a supermassive black ...
After decades of research, scientists say they have finally discovered the origins of quasars, the most powerful objects in the universe.
