n. (context astronomy English) A star which explodes, increasing its brightness to typically a billion times that of our sun, though attenuated by the great distance from our sun. Some leave only debris (Type I); others fade to invisibility as neutron stars (Type II).

thumb|right|upright=1.2| SN 1994D (bright spot on the lower left), a type Ia supernova in the NGC 4526 galaxy A supernova is an astronomical event that occurs during the last stellar evolutionary stages of a massive star's life, whose dramatic and catastrophic destruction is marked by one final titanic explosion. For a short time, this causes the sudden appearance of a 'new' bright star, before slowly fading from sight over several weeks or months.
Only three Milky Way naked-eye supernova events have been observed during the last thousand years, though many have been telescopically seen in other galaxies. The most recent directly observed supernova in the Milky Way was Kepler's Star in 1604 ( SN 1604), but remnants of two more recent supernovae have been found retrospectively. Statistical observations of supernovae in other galaxies suggest they should occur on average about three times every century in the Milky Way, and that any galactic supernova would almost certainly be observable in modern astronomical equipment.
Supernovae are more energetic than novae. In Latin, Nova means "new", referring astronomically to what appears to be a temporary new bright star. Adding the prefix "super-" distinguishes supernovae from ordinary novae, which are far less luminous. The word supernova was coined by Walter Baade and Fritz Zwicky in 1931. It is pronounced with the plural supernovae or supernovas (abbreviated SN, plural SNe after "supernovae").
During maximum brightness, the total equivalent radiant energies produced by supernovae may briefly outshine an entire output of a typical galaxy and emit energies equal to that created over the lifetime of any solar-like star. Such extreme catastrophes may also expel much, if not all, of its stellar material away from the star, at velocities up to or 10% of the speed of light. This drives an expanding and fast-moving shock wave into the surrounding interstellar medium, and in turn, sweeping up an expanding shell of gas and dust, which is observed as a supernova remnant. Supernovae create, fuse and eject the bulk of the chemical elements produced by nucleosynthesis. Supernovae play a significant role in enriching the interstellar medium with the heavier atomic mass chemical elements. Furthermore, the expanding shock waves from supernova explosions can trigger the formation of new stars. Supernova remnants are expected to accelerate a large fraction of galactic primary cosmic rays, but direct evidence for cosmic ray production was found only in a few of them so far. They are also potentially strong galactic sources of gravitational waves.
Theoretical studies of many supernovae indicate that most are triggered by one of two basic mechanisms: the sudden re-ignition of nuclear fusion in a degenerate star or the sudden gravitational collapse of a massive star's core. In the first instance, a degenerate white dwarf may accumulate sufficient material from a binary companion, either through accretion or via a merger, to raise its core temperature enough to trigger runaway nuclear fusion, completely disrupting the star. In the second case, the core of a massive star may undergo sudden gravitational collapse, releasing gravitational potential energy as a supernova. While some observed supernovae are more complex than these two simplified theories, the astrophysical collapse mechanics have been established and accepted by most astronomers for some time.
Due to the wide range of astrophysical consequences of these events, astronomers now deem supernovae research, across the fields of stellar and galactic evolution, as an especially important area for investigation.
A supernova is an astronomical event, a type of stellar explosion.

Supernova is the debut and only solo studio album by Lisa Lopes of TLC.
Supernova is a 2000 science fiction horror film, from Metro-Goldwyn-Mayer. The film was written by David C. Wilson, William Malone and Daniel Chuba and directed by Walter Hill, credited as "Thomas Lee." "Thomas Lee" was chosen as a directorial pseudonym for release, as the name Alan Smithee had become too well known as a badge of a film being disowned by its makers.
It was originally developed in 1988 by director William Malone as "Dead Star," with paintings by H. R. Giger and a plot that had been called " Hellraiser in outer space." Jack Sholder was hired for substantial uncredited reshoots, and Francis Ford Coppola was brought in for editing purposes. Various sources suggest that little of Hill's work remains in the theatrical cut of the film. The film shares several plot similarities with the film Event Horizon, released in 1997, and Alien Cargo, released in 1999.
The cast featured James Spader, Angela Bassett, Robert Forster, Lou Diamond Phillips, Peter Facinelli, Robin Tunney, and Wilson Cruz. This film was shot by cinematographer Lloyd Ahern and scored by composers David C. Williams and Burkhard Dallwitz.
Supernova is a British comedy television programme produced by Hartswood Films and jointly commissioned by the BBC in the UK and UKTV in Australia. It follows Dr Paul Hamilton ( Rob Brydon), a Welsh astronomer, who leaves a dull academic post and unloved girlfriend for a new job at the Royal Australian Observatory, deep in the Australian outback. The comedy centres on his difficulties adjusting to life in the outback and his eccentric fellow astronomers. The first series was released in the United Kingdom and Australia in October 2005 and consisted of six 30-minute episodes. The second series began airing on 3 August 2006 in the UK.
The exterior scenes were shot at Broken Hill in New South Wales, Australia. The observatory itself is a CGI creation, according to the DVD commentary, and only a partial doorway was constructed on site for filming purposes.
