Yes, quasars are galaxies where the central black hole is turned on and consuming material.
quasars as explained in steven hawkings book "the brief history of the big bang to the black hole" states at the center of are galaxie is a massive black hole thousand of millions times larger then the sun and its gravatational pull is sopposedly the reason why are galaxie is spiraled.
Yes
More precisely, quasars are high-energy galaxy CORES, compact enough to appear starlike, yet emitting more radiation than a million "ordinary" galaxies.
Well, we don't really know how they are formed, the most likely explanation is: Quasars are formed by enormous redshifts in a star which gives it, it's energy.
A Supernova Explosion
No. Quasars have the highest energy output of any type of object in the known universe.
A quasar is not a galaxy. A quasar is an intense energy source associated with a supermassive black hole that is actively feeding. All quasars are located at the centers of galaxies.
1965 Galaxies came in 4 trims: Galaxie, Galaxie 500, Galaxie 500 XL, and the top-of-the-line Galaxie 500 LTD.
Quasars have been known to emit over a thousand times the energy of the Milky Way. As the Milky Way contains upwards of 400 billion stars, the likelyhood of the energy output of 5 million Suns is probably true or greatly underestimated.
Quasars emit more energy than anything else in the universe. Quasars are massive black holes at the cores of some galaxies, swallowing matter and stars and ejecting them out collimated bipolar jets of matter and radiation which stretch out hundreds of thousands of light years. Since there are quasars in galaxies close by, these indicate the evolution of our universe.
The word quasar refers to a quasi-stellar radio source. Quasars are astronomical bodies that produce vast amounts of energy. The first Quasars have been discovered in the late 1950s.
Quasars are thought to be galactic black holes which are releasing focused energy from an accretion disk. The temperature could be as high as hundreds of millions of kelvins, but is detected due to its extremely high luminosity.
