Betelgeuse Brightens by 50% in Unexpected Event Before Supernova

Betelgeuse, a dying red giant star, is now shining 50% brighter than usual, following a mysterious dimming in 2019 caused by an enormous explosion. Scientists are keeping a close eye on Betelgeuse, as it is expected to explode into a supernova visible from Earth, though likely not for thousands of years. Betelgeuse's weird behavior is likely linked to the Great Dimming of 2019 and 2020, and the explosion was so massive that it created a dense cloud of cosmic dust that stood between the Earth and Betelgeuse, obscuring the star.
