The remnants of the giant stellar explosion can still be seen today. This image combines data from the Spitzer Space Telescope , Hubble Space Telescope and Chandra X-ray Observatory. Credit: NASA
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]
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.
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
The explosion should be visible to the unaided eye for several days and just over a week with binoculars before it dims again. Keep an eye out online for reports that the explosion has occurred.
Months after astronomers witnessed the explosion of a distant star, they spotted something they have never seen before: energetic signs of life releasing from the stellar corpse about 1 billion ...
Lundmark gives a list of 60 suspected novae, then the generic term for a stellar explosion, in fact covering what is now understood as two distinct phenomena, novae and supernovae. The nova of 1054, already mentioned by the Biots in 1843, [7] is part of the list. It stipulates the location of this guest star in a note at the bottom of the page ...
