We Are Living Inside a Huge Cosmic Bubble And We Just Found Out

Earth is sitting inside a giant cavity in the Milky Way, carved out by exploding stars. Inside it, our Solar System is drifting through a cloud of gas and dust. For decades, the only way to study that cloud was through starlight passing through it.

Then researchers melted 295 kilograms of Antarctic ice that froze between 40,000 and 81,000 years ago. Inside it, they found a handful of atoms of iron-60, a radioactive form of iron that only massive stars and supernovae produce. And there was less of it than in modern snow.
