On July 1 2025 the ATLAS survey spotted 3I/ATLAS, only the third confirmed object known to have arrived from another star system after 1I/‘Oumuamua and 2I/Borisov. Racing through the solar system on a hyperbolic orbit, this volatile-rich comet offers an unprecedented chance to study the chemistry, physics and origins of material forged around an alien sun. In this 22-minute deep-dive we trace the discovery, orbital dynamics, composition, planned spacecraft observations, links to planet formation and even the astrobiological implications of 3I/ATLAS before it slips back into interstellar night. Join us for the full story of the cosmic messenger that’s turning a rare curiosity into a new field of routine science.
