Betelgeuse is a red supergiant star located in the constellation Orion that is nearing the end of its life cycle. It has exhausted its core hydrogen fuel and is now fusing helium into heavier elements, which will lead to a brilliant supernova event. Astronomers have studied Betelgeuse's surface features, temperature variations, and other properties using various techniques. In late 2019 and early 2020, the star experienced an unusual dimming event, leading to speculation that it might be on the verge of going supernova. Studying its eventual supernova explosion will provide valuable insight into the late stages of stellar evolution.
