Betelgeuse's Mysterious Behavior Sparks Supernova Speculation.

Betelgeuse, a prominent star in the Orion constellation, has been increasing in brightness since early April, currently shining at over 140% of its "usual" brightness. This has sparked speculation about a potential supernova explosion, but there is no concrete evidence supporting this hypothesis. If Betelgeuse were to explode, it would not pose a threat to Earth, but it would be visible in the night sky for weeks or even months.
