Did we just lose Betelgeuse?


Maybe we just lost Betelgeuse.


This red giant star, on the boot of Orion (the name is Arabic) was a curiosity in children’s astronomy books in the 1950s.

Anton Petrov discusses the gravitational waves that might have come from the area.

He also says that the star could have gobbled up a binary companion, which would account for faster spin and more nitrogen. 

The star is large enough to almost consumer Jupiter.
