When the star dimmed in 2019, astronomers quickly realized the cause was not an immediate supernova but a massive cloud of dust ejected from the star's surface combined with a temporary drop in surface temperature. The star is currently fusing helium into carbon and oxygen in its core.
Is Betelgeuse Dead Coming Supernova: Understanding the Current Threat
Rapid mass loss leading to the formation of dust clouds. Asymmetry in the star's shape and surface temperature.
When this iron core collapses under its own gravity, it will trigger a supernova explosion. This dramatic dimming, known as the Great Dimming, led to widespread speculation that the famous red supergiant in Orion was on the verge of a supernova explosion.
Is Betelgeuse Dead Coming Supernova The Latest on Star's Explosion Potential
Understanding Betelgeuse's Current State Betelgeuse is a red supergiant, a star so massive that it burns through its nuclear fuel at a rate vastly faster than our Sun. The star is simply behaving like a complex, giant star, subject to the physics of stellar evolution rather than a countdown timer.
