Interstellar Comet 3I/ATLAS is almost as old as the universe itself

Interstellar Comet 3I/ATLAS, discovered in 2025, exhibits carbon isotope signatures indicating ~12 billion years old—roughly 3× the age of the solar system. The finding suggests solar system comets are anomalous; upcoming Vera Rubin Observatory surveys will likely discover more interstellar objects, reshaping planetary-formation models.
