Two astronomers who examined old data from the Voyager missions believe they have identified two small moons hidden inside Uranus’ rings. The discovery is in a paper due to be published in the Astronomical Journal.
Back in 1986, Voyager 2 became the only spacecraft to ever visit the seventh planet from the Sun. The probe spent a whirlwind few days taking measurements of the planet’s weather, rings, moons, and pretty much everything else. Even 30 years later, scientists are still analyzing that data and discovering new things about Uranus, including this potential new discovery of two moons.
