Question

qhat is quazar ...detail answer??

Answer 1

A quasar is powered by a supermassive black hole at the centre of a galaxy. If there is enough material near to the supermassive black hole it will start to fall into the black hole creating an accretion disc. It takes a long time for material to fall into a black hole. As more material falls into the accretion disc it gets superheated by friction and gravitational effects to the point where it emits huge amounts of energy. This is a quasar.

The quasars we have observed are very distant. They are billions of light years away. This means that they are young galaxies and we are seeing them as they were in the early days of the universe.

why the energy release of quazars are greater than supernovas? And Name the stars which forms quazars?

FIRST SEE HOW QUAZARS ARE FORMED:-

QUAZARS ARE FORMED WHEN THE AMOUNT OF DUST AND GAS ARE RELEASE BY THE WYPERMASSIVE BLACK HOLE INTHE CENTER OF THE GALAXY . IT GIVES DUST AND GAS TILL WHEN IT IS EXHAUSTED IN THE BLACK HOLE .

AHD IT IS FORMED AT THE DISC SHAPED AT TH EDGE OF THE BLACK HOLE . WHEN GAS AND DUST ARE EXHAUSTED THEN IT REMOVE FROM THE BLACK HOLE .

AND THE SUPERNOVA RELEASE 10 ⁴⁴ JULOES OR WATT ENERGY .

BUT , THE QUAZARS RELEASE MORE ENERGY THAN THE SUPERNOVA BECAUSE IT HAS MORE ENERGY GOT BY BLACK HOLES.

So , the energy release of quazars are greater than supernovas .

BLACK HOLES IS MADE BY M TYPE STARS .

BUT , THE QUAZARS ARE FORMED BY BLACK HOLE .
