Humanity's encounter with interstellar object 3I/ATLAS has veered from astronomical curiosity into the centre of a scientific quandary that challenges long-held assumptions about cosmic visitors.

3I/ATLAS, detected moving through our solar system from beyond in July 2025, is only the third interstellar object ever observed. Its discovery by the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey generated immediate global scientific interest due to its hyperbolic trajectory and high velocity.
