For the first time, humanity holds in its hands a material record of where the Solar System has traveled through the galaxy. Trapped in Antarctic ice cores spanning 80,000 years, rare iron-60 isotopes — atoms born only in the deaths of stars — reveal that Earth has been drifting through a cloud of ancient supernova debris, moving from its thinner edges into a denser interior. It is a discovery that transforms the ice beneath our feet into a cosmic logbook, and the sky above into a history we are still passing through.
