INTERSTELLAR COMET 3I/ATLAS IS NOT HIDING FROM EARTH: The internet is buzzing with claims that interstellar Comet 3I/ATLAS is “hiding behind the sun.” It’s not. Coronagraphs on GOES-19, SOHO, and NASA’s new PUNCH mission are watching it every day–and it’s behaving like a comet, not a spaceship.

 3I/ATLAS AT PERIHELION: Is Comet 3I/ATLAS really a spaceship? We’re about to find out. On Oct. 29th, the interstellar object will make its closest approach to the sun. Perihelion is the perfect time to perform a Solar Oberth maneuver or to deploy stealthy probes. If we see any unexpected non-gravitational acceleration, artificial lights, or excess heat (engine activity), it could point to alien tech. Otherwise, 3I/ATLAS is what it appears to be–a comet. Contrary to widespread reports, we can see 3I/ATLAS from Earth, so this will be a legitimate “acid test” of the spaceship hypothesis.
