What Did Voyager 1 Discover at the Edge of Our Solar System?

Have we missed an entire planet beyond Neptune? Planet Nine remains a hypothesis. In this cinematic space investigation, ASTROLECT follows the unusual orbits of distant icy worlds, the limits of telescope searches, and Ammonite (2023 KQ14), announced in 2025. Why could a large planet be so difficult to see? Could the way we search shape the patterns we find? And what would turn an intriguing clue into a confirmed discovery? Subscribe to ASTROLECT for cinematic investigations into the mysteries of our universe.
