Betelgeuse

Betelgeuse is a giant red star in the top left corner of the constellation Orion, which you can easily spot in the winter night sky. It's so incredibly huge that if you placed it where our Sun is, it would stretch all the way past Jupiter's orbit! Betelgeuse glows red because its surface is 'only' about 3,500 degrees hot – much cooler than our Sun, but it shines 100,000 times brighter. Sometime in the next 100,000 years, it will explode as a supernova and be visible in the daytime sky for several weeks.
