Description
After giant stars have finished burning their nuclear fuel, they undergo a supernova explosion. This explosion blows off the outer layers of a star into a beautiful supernova remnant. The central region of the star collapses under gravity. It collapses so much that protons and electrons combine to form neutrons. Hence the name "neutron star".

A neutron star is about 10-20 km in diameter and has the mass of about 1.4 times that of our Sun. This means that a neutron star is so dense that on Earth, one teaspoonful would weigh a billion tons!

Pulsars are spinning neutron stars that have jets of particles moving almost at the speed of light streaming out above their magnetic poles.

The image above illustrates the magnetic poles of a pulsar in the middle of nebula.
