A quasar is a black hole in the center of a galaxy that because of the friction created by the gases sliding past each other becomes a very bright celestial body. There are two trails of radiation coming off the poles caused by electrons in the magnetic field around the black hole. Quasars are normally billions of lightyears away, the closest ones being 3 billion lightyears away. We are actually set on a collision course with the Andromeda Galaxy, and when we collide(in 5 or 6 billion years) we might produce a quasar. Quasars are so bright that they outshine nearby stars.We can't see them though.

When a quasars top is set directly at us it is called a blazar.
Streams of energy around the black hole form what is called a DRAGN. I don't remember what the acronym stands for but they actually do look like dragons.

Quasars form when energy and matter gets fed into the black hole in immense quantitys.

I think he's right there. There's always going to be stuff we don't know, ESPECIALLY in the Cosmos. more(+)

We do know, though that it does take up a large quantity of the universe.
Dark energy, on the other hand, is what is expanding the universe. It is supposedly speeding us up as well.
Yet we still don't know much about it. Again "dark."  close(-)
