Betelgeuse's Unusual Brightening: A Sign of Supernova?

Betelgeuse, the red supergiant star, has brightened by almost 50%, leading to speculation about its evolutionary stage and when it will explode as a supernova. New research suggests that it could explode sooner than expected, but the exact stage of core carbon-burning is difficult to determine. Betelgeuse is a pulsating variable star with multiple cycles, making it complex and challenging to understand. When it eventually explodes, it will be visible to the entirety of humanity and provide an unprecedented opportunity to study stellar evolution, supernovae, and stellar remnants.
