On the Edge of: Supernova Remnants
Some scientists are interested in supernova remnants (SNRs), i.e., the
remains of exploded stars. Supernova remnants are actually hot gases that
have been hurtled into space by the force of a supernova (SN) explosion. Some
of the remnants are thousands of years old and many hundreds of light
years wide. Supernova remnants are important to astronomers because they are
the major source of energy, heavy elements and cosmic rays in our Galaxy. In
order to understand how our Galaxy evolves, how new stars are created, how gas
is recycled and energy is redistributed, it is essential to understand
SN explosions and their remnants. The general areas of SNR research can be
divided up into the four listed below:
