There have been a number of odd and bizarre theories for quasi-stellar radio sources, or "quasars". The current hypothesis is that they surround black holes in the centers of active galaxies.
In fact, we suspect that our own Milky Way galaxy has a supermassive black hole in the center, and that it may once have been an "active galaxy". If so, that explains why there are no ancient aliens in the galaxy; the radiation would have killed them all billions of years ago!
Quasars are produced by the friction in the accretion disk surrounding a black hole and we believe that there are supermassive black holes at the center of not just our own galaxy but the center of all galaxies.

Quasars are thought to be distant super-massive black holes.
Quasars are related to supermassive black holes in the center of galaxies.
No they cannot be mistaken for stars as stars can be seen by the human eye & Quasars cannot.
Bright, distant, powerful, energetic, at the center of the galaxy.
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.
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.
Quasars still exist.
Quasars appear starlike, but each emits more energy than 100 giant galaxies. They are thought to be at the centre of galaxies, their brilliance eminating from the stars and gas falling toward an immense black hole at their nucleus.
quasars
No. Quasars are at the centers of distant galaxies.
The first quasars were discovered in the 1950's
