It is a type of stellar explosion that ejects material with an unusually high kinetic energy, an order of magnitude higher than most supernovae, with a luminosity at least 10 times greater. Hypernovae release such intense gamma rays that they often appear similar to a type Ic supernova , but with unusually broad spectral lines indicating an ...
Astronomers predict that a “new star” will become visible after an explosive event in the Northern Crown constellation, and it could happen anytime.
Astronomers studying the site of a supernova seen 843 years ago have captured an image of the strange filaments left behind by the stellar explosion.
Multiple telescopes observed a rare cosmic explosion called a kilonova that created heavy elements in space, including some necessary for life. Explosion 1 million times brighter than the Milky ...
NASA artist's impression of the explosion of SN 2006gy, a superluminous supernova. A super-luminous supernova (SLSN, plural super luminous supernovae or SLSNe) is a type of stellar explosion with a luminosity 10 or more times higher than that of standard supernovae. [1]

This is a tale of survival.In the deep cosmos, the Hubble Space Telescope found evidence that a star remains after its companion star (they orbited each other) went supernova — an extremely ...
Supernova impostor, stellar explosions that appear similar to supernova, but do not destroy their progenitor stars Failed supernova; Luminous red nova, an explosion thought to be caused by stellar collision; Solar flares are a minor type of stellar explosion [1] Tidal disruption event, the pulling apart of a star by tidal forces
