Uranus and Neptune may not be the icy worlds we’ve long imagined. A new Swiss-led study uses innovative hybrid modeling to reveal that these planets could just as easily be dominated by rock as by ...

Uranus and Neptune remain two of the most mysterious objects in the solar system, primarily because they have been visited only by NASA's Voyager 2 spacecraft in 1986 and 1989, respectively. Their ...

Growing evidence suggests that a subsurface ocean lurks beneath the icy surface of Uranus' moon Ariel, but new research, published in Icarus, characterizes the possible evolution of this ocean, and ...

Ariel, one of Uranus’ moons, may once have contained a subsurface ocean more than 100 miles deep beneath its fractured icy shell. The finding, combined with similar evidence from Miranda, suggests the ...

Carbon from deep grooves on Uranus’ moon Ariel? Ariel has carbon dioxide ice and other carbon deposits on its surface. How did they get there? The study last year suggested they originated from within ...

Uranus has 29 moons orbiting it. The first two moons Herschel spotted in 1787 were Oberon and Titania, and they are Uranus's largest moons. There is another Uranus moon that the James Webb Space ...

The moons that orbit Uranus are already known to have unusual characteristics: some are heavily cratered, others have tectonic features or a patchwork of ridges and cliffs. Using the Hubble space ...
