All large moons in the solar system, including Uranus's, are tidally locked. This means that gravity has matched their spin so that the same side always faces their parent planet while they orbit.

Getting a probe to the icy giant planets takes some time—a journey to Uranus could take as long as 13 years, even with a gravity assist from Jupiter. However, several ideas are in the works to speed ...

New research on the Uranian moon Ariel suggests the icy world may be hiding a deep secret. Credit: NASA / JPL Scientists think one of Uranus' moons may once have had an ocean roughly 100 miles deep — ...

When Voyager 2 flew by Uranus and Neptune 40 years ago, astronomers were surprised that it detected no global dipole magnetic fields, like Earth's. The explanation: the ice giants are layered and ...

A new computer model can be used to detect and measure interior oceans on the ice covered moons of Uranus. The model works by analyzing orbital wobbles that would be visible from a passing spacecraft.

The planet Uranus, photographed by NASA’s Voyager 2 spacecraft in 1986. The planet and its moons are expected to be the target of NASA’s next major mission to the outer solar system. When NASA’s ...
