If Betelgeuse were to explode, it would be a spectacular event visible from Earth, potentially even during the day. Betelgeuse is a red supergiant star in the constellation of Orion, and its explosion would likely result in a supernova, releasing an immense amount of energy and producing a bright burst of light that could be visible for weeks or even months. While it's a fascinating astronomical event to ponder, there's no need to worry about it causing harm to Earth. Betelgeuse is located about 700 light-years away, so even if it were to explode, the effects here would be limited to a breathtaking cosmic light show.
