That would mean Betelgeuse only evolved into a red supergiant relatively recently (in cosmic terms), so it might take quite a while for the star to completely exhaust its fuel. "To answer the ...

"And yet there's still room to make significant new discoveries: in this case, a sunlike star hiding in plain sight, in the immense glare of a red supergiant. That is what excites me the most." ...
