Quasar Facts: Learn About These Active Galactic Nuclei!
A quasar, a quasi-stellar object, or QSO, is a very bright active galactic nucleus (AGN) driven by a colossal black hole with a mass extending to billions of solar masses around which an accretion disc is embedded.
Although the initial quasars were spotted as radio waves, this was shortly realized that finding quasars more effectively could be done by looking for objects that were bluer than a normal star. Photographing huge portions of the skies through three different filters could be done with high efficiency.
Quasars have huge radiant energy; the most intense quasars have brightness numerous times larger than the Milky Way. Quasars are usually classified as a subcategory of the more broad class of AGN.
The genesis of quasar redshifts is cosmological. Quasars emit more energy than a hundred regular galaxies put together. Numerous researchers claim that quasars are the universe's most distant objects ever discovered.
Quasars emit massive amounts of energy and can shine a trillion times more luminous than the Sun. Colossal black holes in the center of the galaxies where quasars are found are believed to be their energy source.
Quasars are distant objects visible to us in space, according to scientists. IC 2497, the nearest known Quasar, is 730 million light-years away from us.
Perhaps a quasar previously existed in our Milky Way, but it is now extinct. When the Andromeda Galaxy comes into contact with our Milky Way galaxy in 3-5 billion years, we may get a quasar.
