Scientists Find Evidence Earth Is Drifting Through the Ashes of an Exploded Star

Antarctic ice and older sediment samples contain iron-60, a radioactive isotope from supernovae.

Researchers say the signal is likely being delivered by the Local Interstellar Cloud as the Solar System moves through it.

The finding connects Earth’s current interstellar environment with debris from an ancient stellar explosion.

It also offers a new way to study the origin and structure of nearby cosmic clouds.
