Meet Betelgeuse: a young, brash star located in the constellation Orion. This massive (20 times the mass of the Sun, but almost 1000 times as large) Red Supergiant is about 8.5 million years old and is expected to become a supernova within the next 1000 years. When this happens, it will outshine the Moon in our night sky.
