If Voyager 2 were pulled into a new star system, its trajectory could be altered, potentially capturing it into orbit around a star, interacting with planets, or even colliding with celestial objects. It could also serve as a long-term artifact and a potential interstellar archive, providing valuable data and a lasting human legacy among alien worlds.

New research suggests Uranus emits more internal heat than previously thought, challenging earlier data from Voyager 2 and aligning it more closely with other giant planets, though it still emits less heat overall. The study analyzed decades of data, revealing seasonal variations and raising questions about Uranus's unique interior structure, which could inform future NASA missions and our understanding of planetary evolution.

Decades after Voyager 2's 1986 flyby of Uranus, scientists have re-analyzed the data to solve mysteries about the planet's magnetosphere. They discovered that a rare solar wind event compressed Uranus' magnetic field, explaining the unexpected electron radiation belts observed. This finding suggests that Uranus' major moons might be geologically active, challenging previous assumptions. The study, published in Nature Astronomy, highlights the importance of timing in space exploration and renews interest in future missions to Uranus.
