There’s an exciting update on the supernova of Betelgeuse. A recent study shows that we may have significantly underestimated the size of the red supergiant and its evolution timeline. Betelgeuse could have almost depleted all its carbon and be on the verge of undergoing a supernova. Researchers say that Betelgeuse may seem to explode in a few tens of years rather than hundreds of thousands of years. This is a big deal because the star is located about 650 light years away from us, which means that what we see now is actually how it appeared 650 years ago. If the study, based on the analysis of the star’s fundamental mode and overtones, is correct, it means that Betelgeuse may have already gone supernova in real-time, and we might be fortunate enough to witness this incredible event in our lifetime.
