As seen from Earth, Betelgeuse as a type II-P supernova would have a peak apparent magnitude somewhere in the range −8 to −12. [176] This would be easily visible in daylight, with a possible brightness up to a significant fraction of the full moon, though likely not exceeding it. This type of supernova would remain at roughly constant ...
Betelgeuse has entered an uncommon period of brightening again, this time rising in brightness by around 50 percent. Is the star about to go 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 suggest it is both smaller — and closer — than astronomers ...
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 ...
Betelgeuse—the star and not the slimy, suit-wearing demon—is one of the most celebrated celestial objects in the night sky. Found in the constellation Orion, Betelgeuse is extremely bright ...
A supernova can briefly emit as much energy as an entire galaxy, brightening by more than 20 magnitudes (over one hundred million times brighter). The supernova explosion is caused by a white dwarf or a star core reaching a certain mass/density limit, the Chandrasekhar limit, causing the object to collapse in a fraction of a second. This ...
−119 [d] or ~R Betelgeuse: L/T eff & AD Widely recognised as being among the largest known stars. [21] Might be the largest star visible to the naked eye. [30] The higher radii estimate assume Mu Cephei is in the Cepheus OB2 OB association. [28] [31] Other sources suggest Mu Cephei and Betelgeuse are likely similar in properties.
Astronomers studying the site of a supernova seen 843 years ago have captured an image of the strange filaments left behind by the stellar explosion.
