Supernova

(SN)
(stellar explosion larger than a nova)

A Supernova (SN) is a stellar explosion more energetic than an ordinary Nova. It is often briefly brighter than an entire galaxy, and fades away over a period of weeks or months. Energy emitted can be on the order of the Sun's entire lifetime. The explosion ejects most of the star's material at up to 10% of the velocity of light, sweeping up interstellar gas and Dust, which is called a Supernova Remnant.

Types:

Supernovae are thought to come from a collapse of the core in large stars (core collapse supernova), or in a White Dwarf accreting enough matter that it collapses (Thermonuclear Supernova, Type Ia).

The absolute brightness of a Type Ia Supernova is thought to be determinable from its spectrum and fade time. These factors plus its apparent brightness are used to estimate distance to the supernova and thus to its Galaxy.
