First kilonova observations by the Hubble Space Telescope [18] A first observational suggestion of a kilonova came in 2008 following the gamma-ray burst GRB 080503, [19] where a faint object appeared in optical light after one day and rapidly faded. However, other factors such as the lack of a galaxy and the detection of X-rays were not in ...

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; Luminous red nova, an explosion thought to be caused ...
In nuclear astrophysics, the rapid neutron-capture process, also known as the r-process, is a set of nuclear reactions that is responsible for the creation of approximately half of the atomic nuclei heavier than iron, the "heavy elements", with the other half produced by the p-process and s-process.
What should be explained is relative brightness. The article on Wikipedia explains that the average brightness of a kilonova is much less than a supernova, but the peak brightness is far greater. 97.82.165.112 19:51, 2 February 2023 (UTC) Kilonova emits only relatively weak electromagnetic radiation.
Geological records suggest that nearby supernova events have led to an increase in cosmic rays, which in turn produced a cooler climate. A greater temperature difference between the poles and the equator created stronger winds, increased ocean mixing, and resulted in the transport of nutrients to shallow waters along the continental shelves ...
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.
Fizzy water may feel trendy now, but it has actually been popular for centuries. The creation of club soda is credited to English chemist Joseph Priestley, who discovered how to infuse water with ...
Supernova nucleosynthesis is the nucleosynthesis of chemical elements in supernova explosions.. In sufficiently massive stars, the nucleosynthesis by fusion of lighter elements into heavier ones occurs during sequential hydrostatic burning processes called helium burning, carbon burning, oxygen burning, and silicon burning, in which the byproducts of one nuclear fuel become, after ...
