Stellar explosion can refer to: Nova; Kilonova; Micronova; Supernova. Type Ia supernova; Type Ib and Ic supernovae; Type II supernova; Superluminous supernova; Pair-instability supernova; Hypernova; Supernova impostor, stellar explosions that appear similar to supernova, but do not destroy their progenitor stars Failed supernova
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.
The issue of whether to add a space between the parent star's name and the planetary designation determined by scientific literature references. In most cases, planets named with Bayer , Flamsteed , and or Variable star designation have a space, but usage with other designations varies e.g. WASP-12b but HD 209458 b .
This object is not thought to be a hypernova; instead, it is likely to be a huge gas cloud being absorbed by a massive black hole. The event was also assigned the random name "ZTF20abrbeie" by the Zwicky Transient Facility. This name and the seeming ferocity of the event led to nickname "Scary Barbie", drawing the attention of the mainstream press.

Also, about sixteen old Soviet nuclear space reactors are known to have released an estimated 100,000 NaK liquid metal coolant droplets 800–900 km up, [5] which range in size from 1 – 6 cm. [5] The greatest risk to space missions is from untracked debris between 1 and 10 cm in size. [ 1 ]
Illustration of a FBOT. In astronomy, a fast blue optical transient (FBOT), or more specifically, luminous fast blue optical transient (LFBOT), is an explosive transient event similar to supernovae and gamma-ray bursts with high optical luminosity, rapid evolution, and predominantly blue emission.

17 August 2017: Gravitational wave detected from merger of two neutron stars (00:23 video; artist concept). On 17 August 2017, the LIGO and Virgo interferometers observed GW170817, [7] a gravitational wave associated with the merger of a binary neutron star (BNS) system in NGC 4993, an elliptical galaxy in the constellation Hydra about 140 million light years away.
