Betelgeuse, that bright red star in Orion, has been acting super weird—dimming, brightening, and now it’s got a secret sidekick star called Betelbuddy! Astronomers think it could go supernova in our lifetime (or not), which would mean a sky show as bright as the full moon but totally safe for us. Imagine losing Orion’s shoulder overnight! Would you want to see a supernova with your own eyes? #Science #Betelgeuse #Supernova
