Betelgeuse Dimming Wasn’t a Supernova—Here’s What Happened

Betelgeuse is a red supergiant star in the constellation Orion, located roughly 700 light-years from Earth. It is about 700 times wider than the Sun and around 15 times more massive. In late 2019, Betelgeuse suddenly became much dimmer—losing about 60% of its brightness. Some people wondered whether the star was about to explode as a supernova. Observations suggested that Betelgeuse had ejected a huge amount of hot material from its surface. As the material cooled, it formed a dust cloud that blocked part of the star’s light. So, Betelgeuse did not explode—it temporarily hid behind its own dust.
