Betelgeuse is a red supergiant that has evolved from an O-type main-sequence star. After core hydrogen exhaustion, Betelgeuse evolved into a blue supergiant before evolving into its current red supergiant form. [98] Its core will eventually collapse, producing a supernova explosion and leaving behind a compact remnant. The details depend on the ...
The Winter Triangle is an astronomical asterism formed from three of the brightest stars in the winter sky. It is an imaginary isosceles triangle [a] drawn on the celestial sphere, with its defining vertices at Sirius, Betelgeuse, and Procyon, the primary stars in the three constellations of Canis Major, Orion, and Canis Minor, respectively.

In Chinese, 參宿 (Shēn Sù), meaning Three Stars (asterism), refers to an asterism consisting of Mintaka, Alnilam, and Alnitak (Orion's Belt), with Betelgeuse, Bellatrix, Saiph and Rigel later added. [29] Consequently, the Chinese name for Mintaka is 參宿三 (Shēn Sù sān, English: the Third Star of Three Stars). [30]
Just like the mischievous Tim Burton character of the same name, the red supergiant star Betelgeuse's head shrank. Scientists watched the star blast its outer surface into space in 2019, an ...
This new study finds its body would only reach around two-thirds that distance, roughly 765 times the diameter of the Sun. Based on this size of the stars, astronomers determined Betelgeuse sits ...
A comet is named after its first independent discoverers, up to a maximum of three names, separated by hyphens. [ 30 ] [ 31 ] The IAU prefers to credit at most two discoverers, and it credits more than three discoverers only when "in rare cases where named lost comets are identified with a rediscovery that has already received a new name."
Supernovae can result from the death of an extremely massive star, many times heavier than the Sun. At the end of the life of this massive star, a non-fusible iron core is formed from fusion ashes. This iron core is pushed towards the Chandrasekhar limit till it surpasses it and therefore collapses.
As Betelgeuse burns through fuel in its core, it has swollen to massive proportions, becoming a red supergiant, the latter phase of giant stars. When the star explodes, the event could be briefly ...
