Across 80,000 years of Antarctic ice, scientists have found a record of where our Solar System has been — not in maps or instruments, but in the fingerprints of dead stars. A team led by nuclear astrophysicist Dominik Koll extracted iron-60, an isotope forged only in supernova explosions, from nearly 300 kilograms of ancient ice, revealing that Earth has been drifting through a cloud of interstellar dust for at least eight millennia. The varying concentrations across time layers tell us something quietly astonishing: we have been moving through a cosmic archive, and the archive has been record
