Quasar - Wikipedia
A quasar (/ ˈ k w eɪ z ɑːr / KWAY-zar) is an extremely luminous active galactic nucleus (AGN). It is sometimes known as a quasi-stellar object, abbreviated QSO. The emission from an AGN is powered by accretion onto a supermassive black hole with a mass ranging from millions to tens of billions of solar masses, surrounded by a gaseous ...

Hubble Quasars - NASA Science
This artist’s concept depicts a distant galaxy with an active quasar at its center. Hubble found that the radiation pressure from the vicinity of the black hole pushes material away from the galaxy’s center at a fraction of the speed of light.
Quasar | Discovery, Structure & Evolution | Britannica
Quasar, an astronomical object of very high luminosity found in the centres of some galaxies and powered by gas spiraling at high velocity into an extremely large black hole. The brightest quasars can outshine all of the stars in the galaxies in which they reside, which makes them visible even at
What is a quasar? - EarthSky
The word quasar stands for quasi-stellar radio source. Quasars got that name because they looked starlike when astronomers first began to notice them in the late 1950s and early 60s.

Quasar - ESA/Hubble
Quasars are amongst the most luminous objects in the known Universe, typically emitting thousands of times more light than the entire Milky Way. They are distinguished from other AGNs by their enormous luminosity, and their enormous distances from Earth.
Quasar - Definition, Formation, Facts in Astronomy - Science Notes and ...
A quasar, short for “quasi-stellar radio source,” is the brightest and most energetic object in the universe. Quasars are the active cores of distant galaxies, powered by supermassive black holes devouring surrounding matter.
Quasar - Simple English Wikipedia, the free encyclopedia
Scientists now agree that a quasar is a compact region in the center of a massive galaxy surrounding a central supermassive black hole. [5] Its size is 10–10,000 times the Schwarzschild radius of the black hole. The energy emitted by a quasar is gravitational energy, created from mass falling onto the accretion disc around the black hole.
