The Laser Interferometer Gravitational-Wave Observatory (LIGO) and Virgo detectors recorded a “burst” of gravitational waves this week, from an area of sky near the red supergiant Betelgeuse. This unanticipated burst has been dubbed, for now, S200114f. It’s prompting some interesting chatter on Twitter because Betelgeuse has undergone an unusual dimming in recent weeks, and some astronomy enthusiasts have wondered if it were about to explode. Betelgeuse has not exploded. It’s still there. Still, a supernova explosion of Betelgeuse might be linked with a gravitational wave burst. As Jackson Ryan explained on CNET last night (January 14, 2020):
