A new study suggests that the interstellar comet 3I/ATLAS might have come from the largely unexplored frontier of the Milky Way, offering a rare look into the galaxy's early structure and dynamics. The comet, which is only the third known object from outside our solar system, is being carefully observed as it speeds through our region of space. Its composition, trajectory, and origins are now the subject of a growing number of models attempting to trace where it may have originated, perhaps from a dense and older component of our galaxy. 3I/ATLAS Could Be a Relic from the Milky Way's Early Frontier, Astronomers Propose According to recent analyses, one compelling possibility is that 3I/ATLAS was ejected from the Milky Way's thick disk—a region containing older stars and stellar remnants—rather than the more studied spiral arms. This idea comes from modeling its incoming speed, direction, and chemical signature, which appear somewhat different from typical solar-system comet...
