Betelgeuseball is a red supergiant star in the Orion constellation

(on his shoulder). He is very old, near the end of his life. His light takes 500 years to reach Earth-iconEarthball, so as far as we know he could have exploded in a supernova by now. It is said that when he does blow up, he will be brighter than Moon-iconMoonball in the sky. Saying his name three times makes him appear. If he blew up, Earth-iconEarthball could be annihilated by the gamma ray bursts emitted by the explosion, which are the second biggest explosion in the universe after the Big Bang, and turned into a wasteland only populated by insects. It's said explosions of other stars have killed off 6-iconalien civilizations in the past and will kill Earth-iconEarthball's in the future. A star like him has already done the deed 450 million years ago, killing off 2/3 of all life.
