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.
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 ...
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
SN 1054 remnant (Crab Nebula).. A supernova remnant (SNR) is the structure resulting from the explosion of a star in a supernova.The supernova remnant is bounded by an expanding shock wave, and consists of ejected material expanding from the explosion, and the interstellar material it sweeps up and shocks along the way.
South Carolinians may soon have the chance to view a spectacular stellar event that happens once a generation. According to NASA, the T Coronae Borealis, nicknamed the Blaze Star, lies 3,000 light ...
