Betelgeuse is a pulsating semi-regular variable star, which means it gets slightly bigger and smaller. It varies every 125 days, every 400 days, even every 2,200 days. The dimmest that's ever been seen is so much so that they call it now the great dimming. And it predicts pandemics? Is that the takeaway? Of course not.
