What is a Supernovae
Supernovae are vast explosions in which a whole star is blown up. They are mostly seen in distant galaxies as `new' stars appearing close to the galaxy of which they are members. They are extremely bright, rivalling, for a few days, the combined light output of all the rest of the stars in the galaxy.  More

Pulsars
White dwarfs, neutron stars, black holes: this is a list of objects in which each one is smaller, denser and more extreme in its physical conditions than the one before. The compression is a result of the familiar force of gravity, but the condensed stars which result are outside our Earth-bound experience. A matchbox-sized piece of white dwarf material would weigh tens of tons, while the mass of a battleship in neutron star material occupies the space of a pinhead.  More
