Description

Winds from the hot O star, BD +60°2522, slam into surrounding interstellar gas, heating it and shaping a bubble in space. The star itself is some 45 times the mass of our Sun, while the Bubble is some 7 light years across. To support itself against the force of gravity trying to crush it, the star is burning hydrogen at an incredible pace. When that is done, it'll burn through helium, and carbon and oxygen and up the periodic table. But once it hits iron, the fate of this star is sealed, and gravity will have it's final victory. The star will die in a spectacular supernova in something like 10 million years.
