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 supernova was about 21 million light-years from Earth and is expected to have left behind either a neutron star or black hole, based on current stellar evolution models. The supernova is located near a prominent HII region, NGC 5461, in an outer spiral arm of the bright galaxy. [3] By 22 May 2023, SN 2023ixf had brightened to about ...
The aurora is expected to be bright and visible in multiple northern U.S. states Oct. 3 through Oct. 5 as well as from the lower Midwest to Oregon.
SN 2023rve is a type II supernova that happened in the 10th magnitude barred spiral galaxy NGC 1097 on September 8, 2023. [1] Scientists from the McDonald Observatory in the state of Texas, United States, have observed the supernova and conducted photometric measurements, they described it to be the brightest supernova in the sky as of September 12, 2023.
T Coronae Borealis, also known as the "Blaze Star," is actually a pair of stars located 3,000 light-years away. The star system is a recurring nova, with Earth-visible explosions every 79 to 80 ...
The Crab Nebula is a pulsar wind nebula associated with the 1054 supernova.It is located about 6,500 light-years from the Earth. [1]A near-Earth supernova is an explosion resulting from the death of a star that occurs close enough to the Earth (roughly less than 10 to 300 parsecs [30 to 1000 light-years] away [2]) to have noticeable effects on Earth's biosphere.
Observations were acquired twice per night in order to look for small scale fluctuations in the light curve. [3] The brightness and close proximity of SN 2021aefx make it an excellent target for nebular-phase James Webb Space Telescope observations. Kwok et al. (2022) and DerKacy et al. (2023) provided the first demonstration of the impressive ...
