SN 2023ixf is a type II-L [7] [8] (core collapse) supernova located in the Pinwheel Galaxy. It was first observed on 19 May 2023 by KÅichi Itagaki and immediately classified as a type II supernova. [2] Initial magnitude at discovery was 14.9. [2]
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.
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.
Boom.In the colossal Pinwheel galaxy, 25 million light-years away, a star has just exploded and is even visible through small telescopes. The supernova-hunting astronomer Koichi Itagaki discovered ...
SN 2022jli is a Type Ic supernova discovered in 2022 in the spiral galaxy NGC 157 at a distance of about 23 Mpc. The light curve of the supernova exhibited oscillations that are interpreted as an interaction of a companion star of the star that exploded with a compact object, probably a neutron star or a black hole.

Supernova discoveries are reported to the International Astronomical Union's Central Bureau for Astronomical Telegrams, which sends out a circular with the name it assigns to that supernova. [55] The name is formed from the prefix SN , followed by the year of discovery, suffixed with a one or two-letter designation.
By 2000, the Lick program resulted in the discovery of 96 supernovae, making it the world's most successful Supernova search program. [52] In the late 1990s it was proposed that recent supernova remnants could be found by looking for gamma rays from the decay of titanium-44. This has a half-life of 90 years and the gamma rays can traverse the ...
SN 2021aefx was discovered on November 11, 2021, by the Distance Less Than 40 Mpc (DLT40) transient survey in the spiral galaxy NGC 1566 at a distance of 17.69 ± 2.02 Mpc. [1] It is located 61.2″ west and 36.5″ south of the center. [2] It was discovered at apparent magnitude of 17.24 and classified as a high-velocity SN Type Ia. [3]
