NASA scientists and international partners are studying an interstellar object named 3I/ATLAS, using its rare passage through the Solar System to refine early-warning and tracking techniques for future cosmic threats. While the comet poses no danger to Earth, researchers say it provides a valuable opportunity to test global coordination and data-sharing systems used in planetary defence.
