Are quasars part of your solar system?
No. Quasars are at the centers of distant galaxies.
How many quasars are in a galaxy?
No more than one, we think. Quasars are so distant that it is difficult to distinguish details about their parent galaxies.
What are two keys aspects of quasars?
There the most brightest and distant objects.
What do astronomers use to study quasars?
Scientists use radio waves to study distant quasars because quasars emit large amounts of radio waves but not much visible light.
Why do astronomers think that quasars represent an early stage of galactic evolution?
There are more quasars in faraway galaxies, i.e., in the distant past.There are more quasars in faraway galaxies, i.e., in the distant past.There are more quasars in faraway galaxies, i.e., in the distant past.There are more quasars in faraway galaxies, i.e., in the distant past.
How a quasars are formed?
Quasars are thought to be distant super-massive black holes.
Describe two key aspects of quasars?
Bright, distant, powerful, energetic, at the center of the galaxy.
Are distant objects in space called quarks or quasars?
quasars
Can quasars be mistaken for stars since they're distant galaxies with an active nucleus at the center of it?
No they cannot be mistaken for stars as stars can be seen by the human eye & Quasars cannot.
Are quasars part of your solar system?
No. Quasars are at the centers of distant galaxies.
Distant radio sources that resemble stars?
quasars
How long have most quasars that are very distant implies that they were formed?
The fact that most quasars are very distant means they were like that when the Universe was quite a bit younger than it is today.

What is a very energetic distant object that may be powered by a black hole?
Quasars or active galactic nuclei are thought to generate high energy relativistic jets at their poles, powered by a black hole.
