We unpack why it brightened at 6.4 AU, why its coma ran on carbon dioxide instead of water, and how endothermic cooling can refrigerate a nucleus long enough to mute water vapor. Then we follow the strangest sight of all—a razor-thin jet aimed toward the Sun, stretching hundreds of thousands of kilometers—by exploring dust dynamics that favor heavier grains and an outgassing geometry that resists solar pushback.The chemistry is only half the story. Spectra hint at nickel without the usual iron, a ratio some compare to engineered alloys while others tie to natural metal carbonyls that sublimate at low temperatures. On the dynamics side, observers clocked a crisp jet wobble and a nucleus rotation of about 15.48 hours, a level of stability most comets can’t sustain. We weigh non-gravitational accelerations from anisotropic CO2 jets against the temptation to read intent into precision, and we dissect the 0.2% odds of Atlas arriving aligned with the ecliptic. Add a tantalizing historical overlap with the 1977 Wow! Signal, and the debate tilts between rock and rocket.We also go hands-on with the search for technosignatures. Breakthrough Listen aimed the Green Bank Telescope during closest approach and reported no credible narrowband detections after scrubbing radio interference, keeping the focus on physics rather than beacons. As Atlas heads for a March 2026 brush with Jupiter’s sphere of influence, we lay out the tests agencies will run to refine models of non-gravitational forces and dust jets. Most of all, we look forward: with the Rubin Observatory’s Legacy Survey of Space and Time set to ramp up, discovery rates of interstellar objects could jump by orders of magnitude. If the first three already strain our models, what happens when we log dozens more and the patterns emerge—or refuse to?
