A star is matter being compressed (by the force of gravity) wich in turn heats the star and is the mechanism for Nuclear Fussion, subsequently the star expands ( gravity vs. heat). A Quasar on the other hand is not a star at all, it is, in fact dust wich is being pulled towards a Supermassive Black hole (usually at the center of a Galaxy), the dust being Super-accelerated, and rubbing (friction) against other particles, heats up to an incredible temperature and emits extra-ordinary bright light, which we have come to know as Quasars (accretion disc of dust around Supermassice Black hole)

What was proved was not a star in 1963?
Around that time, it became clear that quasars were not stars.
Why are quasars called radio stars?
Because quasars was discovered to be a strong source of radio waves.... --> Hi Armstrong SY 2011 - 2012 of MunSci!! Goodluck on your street dance and book nook!!
Why quasars are so bright?
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.
Why is the sun different from other stars in the universe?
It is not different, just closer to the Earth.
How many quasars are there?
A Quasar is a powerfully energetic and distant galaxy with an active galactic nucleus surrounding a super massive black hole. Quasars show where massive black holes are growing rapidly (via accretion). These black holes grow in step with the mass of stars in their host galaxy.Therefore there are going to billions or trillions of stars - many more than our own galaxy (~400 billion).
Are brighter than stars.?
Quasars A+
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.
The first quasars were called?
Radio Stars
What do the largest and brightest galaxies contain?
quasars.
Distant radio sources that resemble stars?
quasars
How do you know that quasars are not just nearby stars?
The light from quasars - all quasars - is shifted far to the red side of the spectrum. This means that they are moving away from us, at a very high rate of speed. They cannot be "nearby", for that, and a lot of other sound, scientific reasons.
What was proved was not a star in 1963?
Around that time, it became clear that quasars were not stars.
Are quasars much larger than stars?
Yes, a average quasar is the size of our solar system
What makes up a constellation?
stars in different formations
Why are quasars called radio stars?

How pole stars are differrent from the other stars?
its different from other stars coz they remain in the same place unlike other stars.
What characteristics makes it different from most other stars?
It's the central most vital cause of our existence. All the other stars are many astronomical units away and don't influence us that much.
