Betelgeuse just doing what Betelgeuse does best.
Everyone's favourite bonkers red giant is back in the news again, and it has the supernova spotters in a froth. Last time we talked about Betelgeuse, it had gone unusually dim. Never fear, it's back with a vengeance — not just brighter, but pulsing twice as fast! Is the end nigh? Can we expect it to go boom soon? Well ... define 'soon'. Emily has all the answers.
