The Crab Nebula in 60 Seconds (03-31-2008)
In 1054 A.D., a star's death in the constellation Taurus was observed on Earth. Now, almost a thousand years later, a superdense neutron star left behind by the explosion is spewing out a blizzard of extremely high-energy particles into the expanding debris field known as the Crab Nebula.

The Exotic World of Neutron Stars (04-30-2007)
Neutron stars are created when a massive star runs out of fuel and collapses. As the star collapses, the density becomes so immense that protons and electrons are squeezed tightly together to form neutrons. The end result is a star only 20 km across but weighing 1 1/2 times more than our sun and made up mostly of neutrons.
