Quasars have a large black hole, called a "supermassive black hole". The term "supermassive black hole" simply means that it has millions or even billions of solar masses.
A Supermassive black hole .
A quasar is a galaxy that is radiating massive amount of radioactive energy. A quasar MAY have a black hole at it's center. A black hole is just dead star that collapsed in on itself.
A big black hole.
A quasar is believed to have a supermassive black hole at its center. The radiation is emitted outside the black hole's event horizon - from matter that is falling into the black hole.
No. A Quasar is a Black hole in center of some Galaxies. I think our Galaxy has one of them.
Yes, a quasar is a galaxy with a super-massive black hole in its center. The hole being invisible, all light vanishing from the great gravity. The quasar itself, among the brightest, most luminous objects in the universe, is being powered by an accretion disc around the black hole.
Not "the" quasar, but "a" quasar - there are many. A quasar is associated with a supermassive black hole, and those are generally at the center of galaxies.
ALL larger galaxies have a black hole in their center.
A quasar is a galaxy the gives off huge amounts of radiation, sometimes having a black hole at it's center. A black hole is a dead star that was big enough to "curl back in itself, like a snake eating it's tail."1 Or picking oneself up and carrying yourself by your bootstraps.One is a single star, one is a galaxy.(1 my words)
The quasar is bigger. A quasar is a disk of superheated matter that surrounds a supermassive black hole. The mass of the black hole may be greater than that of the disk, but it is compacted into a smaller space.
quasar
No. A quasar is an object observed in some distant galaxies believed to be a supermassive black hole, millions to billions of times the mass of the sun, feeding on superheated matter. A quasar is many times more powerful than the sun.
