A Star Is About To Go Supernova in Our Backyard

A Star Is About To Go Supernova in Our Backyard

In this episode, we look at the terrifyingly unpredictable behavior of one of the largest stars visible to the naked eye.

While our Sun is a stable middle-aged star, Betelgeuse is a celestial sprinter nearing the final, volatile stage of its life.

If placed at the center of our solar system, this gargantuan sphere of churning gas would swallow up every planet out to Mars and potentially engulf Jupiter.

We unpack the mystery of the 2019 "Great Dimming," when the star violently coughed up a massive plume of surface mass, and explore why its rhythmic 400-day pulse has suddenly been cut in half.

We walk through the brutal physics of a core-collapse supernova to map out exactly what will happen when its internal engine shuts down. Located just 640 light-years away, its death will trigger a global alert system, flooding underground neutrino tanks with millions of ghostly particles hours before a titanic shockwave shatters the star’s surface.

We paint a vivid picture of the ultimate light show: a dazzling point of light that will rival the full Moon, cast shadows at night, and remain clearly visible in broad daylight for weeks.

It’s a high-stakes look at an impending cosmic cataclysm and the fundamental question: Are we safe?
