Every atom in our bodies was processed inside the body of an ancient star. In fact, the iron in our blood connects us to one of the most violent acts in the universe — the death of a star in a supernova explosion.
But the stars will all burn out someday. "That's not something we have any doubt about," says NASA astronomer Dr. Michelle Thaller. You can imagine this time in the universe's history as a star-powered Eden. "I wonder if people will have myths about the days when stars rained down free sunlight and free energy," Thaller says.
