The Mysterious Behavior of Betelgeuse: Exploring its Possible Explosion.

Betelgeuse, a variable star, has shown unexpected behavior with a great dimming in 2020 and a subsequent extreme brightening. While Betelgeuse is expected to end its life in a supernova explosion, new models suggest this event could happen within a few thousand years or 1.5 million years into the future. If Betelgeuse does go supernova, it would first emit harmless neutrinos, then quickly brighten and remain visible in the day time for six to 12 months. While cosmic rays produced by supernovas can cause ozone destruction and dangerous UV levels on Earth, a close supernova is rare and may happen only once per billion years.
