Betelgeuse is a red supergiant star 642.5 light years from Earth and is coming to the end of its life. It could explode as a supernova at any time in the next million years, or it could explode tomorrow. This simulation made with Universe Sandbox 2 shows just how much the resulting nebula will expand by the year 10,000 if it explodes sometime soon.
