Now nearing the end of its life, Betelgeuse likely will explode as a supernova and be visible in the daytime sometime in the next 100,000 years. That would be big news because a supernova hasn’t ...

If the latter, that would insinuate that the star is even bigger than we thought, and could go supernova within just a couple ...

Having already fused most of its hydrogen, Betelgeuse has entered a more advanced stage of stellar evolution, one that could ...

Whether a star in the Milky Way goes supernova anytime soon is anyone’s guess. A prime candidate is Betelgeuse, the closest red supergiant star to the solar system at around 550 light-years that ...

The story describes Betelgeuse as “the red giant that marks Orion’s left shoulder.” Reader Chris Jespersen wrote: “I often see Betelgeuse on Orion’s right shoulder…. Am I mistaken?” ...

This figure shows measurements of Betelgeuse's brightness from different observatories from late 2018 to present. The blue and green points represent data from ground-based observatories.

In late 2019 the red supergiant closest to Earth, Betelgeuse, began to rapidly fade in brightness. Initially thought to be a sign that the star was about to go supernova or that it experienced a dust ...
