Scientists often look to distant galaxies for answers, but sometimes those clues are hidden beneath Earths oceans. In a stunning discovery, researchers found radioactive stardust from an ancient cosmic explosion still reaching our planet today. Tiny traces of plutonium preserved in deep-sea crust reveal a story that began millions of years ago. The finding shows that Earth remains connected to powerful events unfolding across the universe. It also offers fresh insight into how the elements around us were first created.

A sprinkling of radioactive plutonium atoms hidden in the ocean floor may trace back to a cosmic cataclysm more than 100 million years ago.
