Supernova - COSMOS 1080p

Supernovae are exploding stars which are broadly classified into two main types depending on the type of star which explodes. The progenitors of a Type Ia supernova (SNIa) is a white dwarf accreting matter from a companion, while the progenitors of core-collapse supernovae are massive stars at the end of their lives.

Supernovae are transient objects. They appear suddenly as a bright star (that can outshine an entire galaxy) at a random position in the sky, and fade relatively quickly never to be seen again. For this reason they are difficult objects to find and study, and astronomers have now established several supernova searches dedicated to locating new supernovae and obtaining rapid and extensive follow-up observations of these objects.
