At 9:02:11 PM Eastern Standard Time on Monday January 13 the 2 LIGO detectors in the USA and the VIRGO detector in Italy noticed an unusual Gravitational Wave, unlike merging Neutron Stars that produce waves that last about 30 seconds and merging stellar mass Black Holes that last about a second this one only lasted for 14 milliseconds. Nobody is quite sure what caused it, the best guess is a unnovae, they have been observed optically a few times in stars too large to go supernova and instead collapse directly into Black Holes and just turn off; no supernova has ever been observed from a star larger than 18 solar masses although stars well over 100 solar masses exist. As it happened this event occurred on a area in the sky near to but not precisely at Betelgeuse's location, but Betelgeuse is still there and probably isn't massive enough to be a unnovae, its eventual fate is probably just a boring old Supernova. And the wave could be caused by something else, 14 milliseconds is pretty short even for a unnovae.
