Betelgeuse: The Red Supergiant Star in Orion

Betelgeuse is a massive red supergiant star marking the shoulders of Orion, and it’s nearing the end of its life. In this video, we explore Betelgeuse’s enormous size, its changing brightness, and why astronomers are closely watching this unstable star. Betelgeuse will one day explode as a supernova, and it may have already happened while the light is still traveling toward Earth. Photo Attributes ▶ Great Dimming in Orion: By H.
