Betelgeuse dimming enigma

Post by brian livesey »

Astrophysicists have concluded that the temporary dimming of the celebrated red supergiant was not, as rumoured, a sign of imminent core collapse, followed by a supernova explosion, nor as was theorised by an obscuring dust cloud. Research published in Astrophysical Journal shows that the dimming was caused by a giant star spot that caused a 40 per cent dimming, making the star 10 per cent cooler. It's reckoned that it could be a million years for Betelgeuse to go supernova, which gives us plenty of time to appreciate this beautiful star.
