Question

What are pulsars and quasars?

Answer 1

Step 1 : Pulsars :

1. These are defined as the spinning neutron stars which have jets of the particles and move almost at the speed of the light streaming out above their magnetic poles.
2. These are composed of 10% electron and 10% neutrons and emit regular pulses of electromagnetic radiation.
3. Pulsars are consists of three layers: a solid core, a liquid mantle and a thin, solid crust.
4. Pulsars spin very fast.
5. These are the highly magnetized rotating neutron stars..

Step 3 : Quasars :

1. Quasars are very high luminosity and are found in the centers of some of the galaxies
2. These are powered by gas spiraling at high velocity.
3. Quasars are likely to form from black holes.
4. They can release energy capable of illuminating a galaxy and equivalent to millions of suns.
5. Currently, more than 200,000 quasars have been identified.
