3I/ATLAS A rare interstellar visitor passing through our cosmic neighbourhood is offering scientists an unprecedented glimpse into a part of the Galaxy vastly different from our own. Comet 3I/ATLAS, one of only three known objects to have entered the Solar System from deep space, is believed to have formed billions of years ago in a cold, distant environment far beyond the reach of our Sun. New research suggests this ancient object may be as old as 10-12 billion years, more than twice the age of our Solar System, making it a rare relic from the early Milky Way.
