Pulsars and Quasars

Pulsar Drawing
Pulsars and quasars are some of the most  interesting object in the cosmos.

Pulsars: Pulsars are fast rotating neutron stars. It is still unknown what causes them to spin so quickly. A pulsar has 2 streams of radioactive particles streaming out of it's poles. The name is just short for pulsating star. They appear to blink in the night sky. There is a pulsar in the center of the famous crab nebula. An average pulsar is just the size of Manhatan. and orbits once every 1 or 2 seconds.


Quasar Animation
Quasars: They are strange even for black holes. A quasar is a supermassiveblack hole in the center of a galaxy (Not all galaxies have one, the milky way and many others do not. Quasars are not very common.) The light from a quasar is emited from it's poles, as you can see from the drawing. The light comes from the gas of stars that are being devoured. Sometimes the gas can spread through hundreds of lightyears. These are called Dragns. It is not possible for a quasar to be a star.
