Betelgeuse, Alpha Orionis (α Ori), is a red supergiant star and supernova candidate located at a distance of 724 ly from Earth in the constellation Orion.

Either way, it will be spectacular! reports at 642.5 light-years from Earth, it would be the closest supernova observed and recorded by humans (closer than the Crab Nebula, which is 6,523 light-years from Earth and is the result of a supernova in A.D While variable stars such as Betelgeuse regularly experience dim and bright phases throughout their lives, this recent dimming … From Earth, a mere 600 light-years away, a Betelgeuse supernova would be spectacular. What would a Betelgeuse explosion look like from Earth? Chenoa van der Boogaard, Physics & Astronomy editor In October 2019, astronomers noticed that Betelgeuse, the red supergiant star that forms the left shoulder of the constellation Orion, was beginning to dim. Astronomer Andy Howell (University of California) and two of his students, Jared Goldberg and Evan Bauer, answered this question and performed simulations to show how bright the supernova … THE supernova of the nearby star Betelgeuse could be the brightest to ever be observed from Earth and would be more visible than a full moon and be bright enough to cast shadows, experts have said. Simulation shows what happens when Betelgeuse explodes as a supernova Update from February 18, 2020: What does it actually look like when the star Betelgeuse explodes as a supernova at some point? This is what we'll see from Earth when Betelgeuse goes Supernova. Betelgeuse Supernova: Pre-Messiah Star of Jacob to Herald Gog Magog War With Iran By Adam Eliyahu Berkowitz December 29, 2019 , 1:48 pm “Before the great and terrible day of Hashem comes,* I will set portents in the sky and on earth: Blood and fire and pillars of smoke.” Read on to find out!

Would we have to worry about harmful radiation from the supernova in Orion? It could happen today, or 100,000 years from now.
