Buried in the ancient ice of Antarctica lies a quiet record of our Solar System's passage through the galaxy — not written in light, but in the radioactive dust of long-dead stars. Scientists have traced the presence of iron-60, an isotope born only in stellar explosions, through ice layers spanning 40,000 to 80,000 years, finding less of it than expected and thereby mapping a chapter of our cosmic journey through the Local Interstellar Cloud. The discovery reminds us that Earth is not a fixed point in the universe, but a traveler, and that the ground beneath our feet carries the fingerprints
