Is interstellar object 3I/ATLAS older than our Sun? Here’s what it might reveal about the origins and observations

Astronomers have discovered 3I/ATLAS, a fast-moving interstellar object detected in mid-2025. Researchers believe this ancient comet, potentially 8-14 billion years old, originated from the Milky Way's earliest era, predating our Sun. Its unique chemical composition, including iron and nickel, further supports its alien origins, offering a rare glimpse into material forged around ancient stars.
