Did Betelgeuse Explode 2024 Date. We know betelgeuse isn’t about to explode anytime soon, but if it ever does, astronomers say they now have a way to give us a few weeks’ warning. That's what happened with the red supergiant star betelgeuse between november 2019 and may 2020.

If betelgeuse does blow, it will be the brightest supernova ever witnessed by humans. Astronomers pointed powerful telescopes at the red giant star betelgeuse, confirming theories that the star had not almost exploded a few years ago, but it did experience a dimming event.
