#Betelgeuse is a massive, highly variable red supergiant star in the constellation Orion that is nearing the end of its stellar life cycle and is destined to explode as a spectacular supernova visible from Earth.

#PPOD: This remarkably detailed view of #Betelgeuse, captured by the Atacama Large Millimeter/submillimeter Array (ALMA), reveals the uneven, bubbling surface of the famous red supergiant about 600 light-years away. Nearly 800 times larger than the Sun, Betelgeuse is covered by enormous regions of hot gas rising from deep within the star, creating the bright hotspots seen across its surface.

An article accepted for publication in the journal "Astronomy & Astrophysics" reports the results of observations of structures that are lasting longer than predicted in the atmosphere of the star Betelgeuse. A team of researchers used the ALMA radio telescope to obtain some of the most detailed views of Betelgeuse's surface ever obtained. This allowed them to study its really uneven surface and the structures within its atmosphere.

An article published in the journal "Astronomy & Astrophysics" offers the best evidence yet for the existence of a companion to the star Betelgeuse. Independent observations will be needed to confirm the existence of the candidate Betelgeuse B. This study suggests it's a star with a mass between 2.6 and 3.1 times the Sun's.
