What is the energy source for quasars?
Quasi-stellar radio sources, or quasars for short, are the ultra-luminous cores of very distant galaxies, blowing opposing jets of charged particles and energetic radiation into space. They are powered by supermassive black holes, weighing in at billions of solar masses.
Also, how do astronomers now explain the fact that the energy emitting regions for quasars are so small?
How do astronomers now explain the fact that the energy emitting regions for quasars are so small? Astronomers have established that quasars and active galaxies have a lot of mass at their centers in a very small volume of space. Regarding this, why do quasars give off energy? Quasars are believed to produce their energy from massive black holes in the center of the galaxies in which the quasars are located. Because quasars are so bright, they drown out the light from all the other stars in the same galaxy.
And another question, why are quasars mostly seen at large distances quizlet?
Why are quasars mostly seen at large distances ? they were most powerful with the Universe was young. hundreds of millions of years. What is the quasar peak? Quasar discovery surveys have demonstrated that quasar activity was more common in the distant past; the peak epoch was approximately 10 billion years ago. Concentrations of multiple, gravitationally-attracted quasars are known as large quasar groups and constitute some of the largest-known structures in the universe.
Thereof, what happened quasar?
Quasar Electronics, Inc. and Quasar Company ceased to exist in 2004. As of 2005, the Quasar name was little used in North America, typically affixed to a few discontinued products from the Panasonic line being offered as value products in drug stores and supermarkets. And another question, what will happen when our galaxy collides with andromeda galaxy in 5 billion years? The result of the collision between Andromeda and the Milky Way will be a new, larger galaxy, but rather than being a spiral like its forebears, this new system ends up as a giant elliptical. Interaction with their surroundings means that the pair will spiral inwards, emitting gravitational waves as they do so.
Correspondingly, what is likely to happen if two galaxies collide quizlet?
-When two galaxies collide the tidal waves cause objects to begin to change their orbital periods according to where the massive object is. This can cause galaxies to become distorted or even rip apart.

- In what sense are the quasars Quasi Stellar?
- Why are there no quasars left what happened to them?
It is the largest object to have hit the Earth. The first direct observation of an extraterrestrial collision of Solar System objects occurred when the comet broke apart and collided with Jupiter in 1994.
