A very small, `superdense' star composed
mostly of neutrons. They are thought to form
when massive stars explode as supernovae,
during which the protons and electrons of the
star's atoms merge, due to intense
graviational collapse, to make neutrons. A
neutron star may have the mass of up to three
Suns, compressed into a globe only 20 km/12
mi in diameter. If its mass is any greater,
its gravity will be so strong that it will
shrink even further to become a black hole.
Being so small, neutron stars can spin very
quickly. The rapidly `flashing' radio stars
called pulsars are believed to be neutron
stars. The `flashing' is caused by a rotating
beam of radio energy similar in behaviour to
a lighthouse beam of light.
