The Cosmic Ash Cloud: A New Frontier for Earth's Galactic Neighborhood Researchers have found concrete evidence that our planet is hurtling through the remnants of an ancient supernova explosion.
By analyzing Antarctic ice cores up to 80,000 years old, scientists from the Helmholtz Zentrum Dresden Rossendorf (HZDR) detected traces of iron 60, a rare isotope forged in supernovae.
This discovery opens a new window into our understanding of the Local Interstellar Cloud, a vast expanse of gas and dust surrounding our Solar System.
