- A Tutorial on Radio Pulsars
The lighthouse model of a radio pulsar shows a rapidly rotating central neutron star with a strong magnetic field, inclined to the rotation axis with radio emission emanating from the magnetic poles.

- Neutron Star Formation
A Type I supernova will be blown to bits, and will not leave behind a dense central remnant. A Type II supernova, however, (one triggered by the collapse of a massive star) will leave behind an ultradense relic, with a density of 100 million tons per cubic centimeter. If the object's mass is less than about 3 solar masses, it forms a stable object known as a neutron star.

- Neutron Stars
Neutron stars are about 10 km in diameter and have 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.

- Neutron Stars and Pulsars
Neutron stars are very dense and spin very fast and are typically only 10-15 km in radius. The collapse of the star causes the matter to be converted into mostly neutrons, hence the name neutron star.

- Neutron Stars and Pulsars
Neutron stars are left behind following supernova type II explosions. They are the collapsed cores of massive stars. Although they were predicted by theory in the 1930s, it was thought that they would be undetectable because of their small size.

- The Forgotten Challenge: Pulsars
In 1967 when Cambridge University radio astronomers Ms. Jocelyn Bell and Dr. (now Professor) Anthony Hewish discovered first one, and then a second regular pulsing source in two widely-separated parts of the sky. Since no pulsing signal sources other than terrestrial man-made ones had ever been seen before, a strong possibility of ET-origin was suspected.
