QuasarĪ Quasar (Quasi-stellar Radio Source) is a type of galaxy of which the nearest, Markarian 231 is located 581 Million Light Years away. A galaxy can contain multiple Pulsars whereas a galaxy will only have one Quasar at the centre. When our own star, the Sun dies in about five billion years time, it will turn into a Planetary Nebula with a white dwarf in the centre. Neutrons are neutrally charge particles where the positive and negative charges have cancelled themselves out. The resultant will be a neutron star, where protons (positively charged) and electrons (negatively charged) have fused together under extreme pressures to create neutrons. When the giant star has run out of fuel and can no longer sustain itself by chemical reaction, it will explode in a supernova explosion. PulsarĪ Pulsar (Pulsating Radio star) is one possible end of life for a Giant Stars, the other possible end is a Black Hole.

It will come as no surprise to anyone that they are totally different. People can be confused by Quasars and Pulsars on the account that they both end with the same letters. What is the difference between a Pulsar and a Quasar?
