Supernova Alert: We May Soon See an Exploding Star in Night Sky

Betelgeuse supernova is one of the most awaited astronomical events. Lying about 650 light years away, Betelgeuse is a red supergiant star on its deathbed. It is in its carbon-burning phase. Earlier, it was believed that the star would go supernova in the next 100,000 years or so. However, a new study shows that we have significantly underestimated the size of Betelgeuse and its evolution timeline. According to new research, the star may seem to explode within the next few decades, instead of hundreds of thousands of years. But how did scientists come to this conclusion? What evidence do they have to back up their idea? Finally, and most importantly, what would happen if the light from Betelgeuse's supernova reaches us while we're still around? The 63rd episode of the Sunday Discovery Series answers all these questions in detail.
