Latest Supernovae 2004-2005

    Listed below are color images and RGB photometry data of recent supernovae.  Young SN tend to be blue since they are hotter and become red (cooler) as they age.  Type Ia SN are white dwarf stars which accrete mass from a companion star until finally exploding.  They are used as "standard candles" and have helped support the theory that the expansion of the universe is accelerating rather than slowing down as expected.  Type II SN are very large explosions of red supergiant stars that end in a black hole or neutron star.
