The explosion will be essentially a point source for our eyes and, while very bright for an object in the night sky, will still be roughly 500,000 times dimmer than the Sun. Hubble Sees Red Supergiant Star Recovering After Blowing Its Top Betelgeuse is a star that is expected to go supernova at some point in the next million years. Someday "soon" the star will run out of fuel, collapse under its own weight, and then rebound in a spectacular supernova explosion. Jared Goldberg/University of California, Santa Barbara/MESA+STELLA. Betelgeuse is 642.5 Light years away, by one estimate and 530 ly by anotherthat means, even though Betelgeuse is nearing the end of its stellar life and will eventually explode in a supernova visible from Earth, it might take another 100,000 years, according to 2021 research. Images of Betelgeuse taken in January 2019, December 2019, January 2020 and March 2020 show the star's unprecedented dimming.
