SN 1054 remnant (Crab Nebula)A supernova is an event in which a star destroys itself in an explosion which can briefly become as luminous as an entire galaxy.This list of supernovae of historical significance includes events that were observed prior to the development of photography, and individual events that have been the subject of a scientific paper that contributed to supernova theory.
NASA's James Webb Space Telescope (JWST) has captured photos of one of the earliest supernovas ever seen, with features appearing like grains and knots found in a cut of wood. "Once upon a time ...
The supernova was a Type Ic supernova, similar to SN 1998bw, the first supernova linked to a GRB. Lightning detectors in India and Germany picked up signs that the Earth's ionosphere was perturbed for several hours by the burst, though only mildly, [ 37 ] [ 17 ] [ 4 ] as well as an enormous influx of electrically charged particles, [ 38 ...
A hypernova is a very energetic supernova which is believed to result from an extreme core collapse scenario. In this case, a massive star (>30 solar masses ) collapses to form a rotating black hole emitting twin astrophysical jets and surrounded by an accretion disk .
The supernova classification type is closely tied to the type of progenitor star at the time of the collapse. The occurrence of each type of supernova depends on the star's metallicity, since this affects the strength of the stellar wind and thereby the rate at which the star loses mass.
A type Ic supernova can produce a GRB if the star is rotating and has an appropriate mass. R136a1 is expected to lose almost all its spin long before core collapse so a GRB is unlikely. [37] The remnant from a type Ic core collapse supernova is either a neutron star or black hole, depending on the mass of the progenitor core. For a star as ...
SN 1006 was a supernova that is likely the brightest observed stellar event in recorded history, reaching an estimated −7.5 visual magnitude, [3] and exceeding roughly sixteen times the brightness of Venus.
The expansion shell has a temperature of around 30 million K, and is expanding at 4,000−6,000 km/s. [2]Observations of the exploded star through the Hubble Space Telescope have shown that, despite the original belief that the remnants were expanding in a uniform manner, there are high velocity outlying eject knots moving with transverse velocities of 5,500−14,500 km/s with the highest ...
