Betelgeuse: Will Orion lose its one member?

Orion is one of the most easily spotted constellations in the night sky. The weird dimming and brightening of one of its “member” star Betelgeuse has kept the astronomers in hopes to see a galactic star go supernova in recent times. The last observed supernova was in the 1600s. So, what makes a star explode? It’s when it runs out of nuclear fuel and collapses under its own mass or it accumulates so much mass that it exceeds a certain mass limit (ChandarShekhar Limit). In this talk, I will discuss how this happens. Is Betelgeuse really going to be a supernova and how will the sky look after it explodes?
