Interstellar comet 3I/ATLAS just made space history—after growing a wild 400,000 km halo (that’s Earth-to-Moon distance!), it started glowing in X-rays. No other comet from another star system has ever done this! Scientists are freaking out because it means we’re getting a front-row seat to how alien ices react to our Sun. Plus, the comet’s turning green and shooting out water vapor. Space is wild right now! #Science #space #comet
