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
Hubble Quasars - Science@NASA The quasar’s brightness is equivalent to about 600 trillion Suns and the supermassive black hole powering it is several hundred million times as massive as our Sun, but even with gravitational lensing making it three times as large and 50 times as bright, only Hubble had the ability to resolve it
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, Clocks, Difference, Facts, Discovery Quasars are the brightest objects in the universe, emitting energy up to a trillion times brighter than our Sun They produce radiation across the entire electromagnetic spectrum, including visible light, ultraviolet, X-rays, and gamma rays
