Description = [[Census: 2,498 pulsars. DU Version 5.6. <br> Upon death, stars
|
|
leave behind one of three possible remnants: a white dwarf, a neutron star, or
|
|
a black hole. Stars that are more massive than the sun will often become
|
|
neutron stars in a violent explosion called a supernova. During a supernova,
|
|
the core of the star collapses under such high pressure that the electrons,
|
|
which normally remain outside the atomic nucleus, are forced to combine with
|
|
the protons in the nucleus. Atomic nuclei break apart, producing what is
|
|
called a degenerate state of matter. The collapse is halted when the material
|
|
cannot be packed any tighter. At this point, the star has a radius of about
|
|
10-15 kilometers. The density of this material is so high that a teaspoonful
|
|
would weigh about 100 million tons on Earth. (Description from URL) <br><br>
