Some speculated that it was an alien spacecraft, but it turned out to be a comet, 3I/Atlas, and it provoked interest from astronomers and astrophysicists eager for insights into galaxies far, far away. Detailed observations from the National Aeronautics and Space Administration (NASA) shot down the alien spacecraft idea, but recent NASA analysis holds clues about the comet's ancient and, literally, alien origins.
