[8] Betelgeuse typically shows only small brightness changes near to magnitude +0.5, although at its extremes it can become as bright as magnitude 0.0 or as faint as magnitude +1.6. Betelgeuse is listed in the General Catalogue of Variable Stars with a possible period of 2,335 days. [8]
This is a list of supernova candidates, or stars that are believed to soon become supernovae. ... Betelgeuse: 05 h 55 m 10.3 s +07° 24′ 25″ Orion ~400–500 [8 ...
This red giant star will, one day, explode as a supernova. Betelgeuse is one of the best-known stars in the night sky, as well as the easiest to find. New examinations of this behemoth star ...
In 2022 a team of astronomers led by researchers from the Weizmann Institute of Science reported the first supernova explosion showing direct evidence for a Wolf-Rayet progenitor star. SN 2019hgp was a type Icn supernova and is also the first in which the element neon has been detected. [137] [138]
An asteroid will briefly eclipse Betelgeuse, a bright star in the Orion constellation, causing it to disappear from view for those in a narrow strip of the globe.
The sixth season premiered on January 9, 2018, and ran through March 13, 2018. The seventh season premiered on January 8, 2019. On December 30, 2019, it was announced that the eighth season would premiere on January 2, 2020. [9] The ninth season premiered on March 24, 2021. [10] The tenth season premiered on March 6, 2022.
A look at the sensational death of stars in supernova explosions which shine as bright as a 100 billion suns and release jets of high-energy matter as gamma-ray bursts and x-ray radiation. Also a look at supernovas recorded throughout history and how stardust creates the building blocks of planets and life.
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 .
