A supernova is a cataclysmic explosion caused when a star exhausts its fuel and ends its life.  Supernovae are the most powerful forces in the universe. All of the heavy elements were created in super [..]

Explosion of a massive star at the end of its life. Supernova explosions are so luminous that they can outshine a galaxy. There are two types of supernovae. A supernova type I is most likely a white dwarf star in a binary system which accretes material that builds up until a nuclear explosion disrupts the star. A supernova type II is a massive star [..]

A star ending its life in a huge explosion. In comparison, a nova is a star that explosively sheds its outer layers without destroying itself.

An exploding star.

exploding star. superposition -

The self-destructive explosion of a star, creating an extremely bright light that becomes invisible over weeks or months.

A gigantic stellar explosion in which the star's luminosity suddenly increases by as much as a billion times. Most of the star's substance is blown off, leaving behind, at least in some cases, an extremely dense core which may be a neutron star.

SN The explosion of a star at the end of its life . Not all stars explode, only those about ten to twenty times more massive than our Sun. A supernova creates the elements that are heavier than iron (such as gold, silver and most of the other metals).

When a star exhausts its nuclear fuel, it under goes a catastrophic collapse. The resulting explosion is known as a supernova. It often is brighter than an entire galaxy.

A star that quite suddenly increases, perhaps a million times, in brightness. It is similar to a nova, but its increase is vastly greater. It never fully returns to its original brightness.

(More accurately, type II supernova.) When a star burns up all its fuel, it collapses and the released gravitational energy blows off its top layers, creating a supernova explosion. What remains of th [..]

One of the three surveys that comprised the second phase (SDSS-II) of the Sloan Digital Sky Survey (SDSS). It featured repeated imaging of Stripe 82 to find these remnants of gigantic explosions from dying stars, together with detailed spectroscopic and photometric followup to get redshifts and lightcurves. The survey discovered almost 500 confirme [..]

Destructive explosion of a star.

The explosive death of a massive star whose energy output causes its expanding gases to glow brightly for weeks or months. A supernova remnant is the glowing, expanding gaseous remains of a supernova explosion.

Stage in the life of a massive star, manifesting itself by an explosion that makes it extremely bright for a time.
