The Betelgeuse in the constellation of Orion is a fascinating star. It’s a red supergiant more than six hundred times the diameter of the Sun, making it one of the largest stars known to astronomers and one of the brightest stars in the night sky. Despite being only 10 million years old, Betelgeuse has already exhausted the hydrogen fuel in its core and is now in the final stage of its life. Eventually, gravity will cause the core to collapse, resulting in a spectacular supernova explosion. This explosion will be so massive and violent that, even though Betelgeuse is 650 light-years away from Earth, it will illuminate the night sky as brightly as the full moon for up to three months. However, we will not witness this dramatic event, as astronomers predict it won’t occur for another 100,000 years.
