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 ...
After a few months or years, when a newly discovered satellite's existence has been confirmed and its orbit computed, a permanent name is chosen, which replaces the "S/" provisional designation. However, in the past, some satellites remained unnamed for surprisingly long periods after their discovery.
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.
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 ...
Mintaka / ˈ m ɪ n t ə k ə /, [17] designation Delta Orionis (δ Orionis, abbreviated Delta Ori, δ Ori) and 34 Orionis (34 Ori), is a multiple star system some 1,200 light-years from the Sun in the constellation of Orion.
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 ...
It is about 110 times brighter than the Sun in visible light wavelengths, but this underestimates its strength as much of the light it gives off is in the infrared; total power output is about 180 times that of the Sun. With a near-infrared J band magnitude of −2.2, only Betelgeuse (−2.9) and R Doradus (−2.6) are
It was discovered on 8 October 1891, by French astronomer Auguste Charlois at Nice Observatory in France. [10] On 12 December 2023, Leona passed in front of the bright star Betelgeuse and occulted it, which caused the star to briefly dim as seen from Central America, Europe, and east Asia. [ 11 ]
