Uranus's swaying moons will help spacecraft seek out hidden oceans

NASA plans to send a spacecraft to Uranus to investigate if its icy moons hide liquid water oceans. University of Texas researchers have developed a computer model to detect these oceans using only spacecraft cameras. The model analyzes small wobbles in a moon's spin to calculate its internal composition. If oceans are found on Uranus's moons, it could suggest numerous potentially life-harboring worlds throughout the galaxy. The technique was previously used to confirm an ocean on Saturn's moon Enceladus.
