For decades, Uranus and Neptune have been filed neatly into the “ice giant” drawer, shorthand for worlds built mostly from ...

Because Uranus and Neptune are so far away, scientists only have educated guesses about the combination of ices and gases that make up these ice giants. While the general understanding is that these ...

Uranus and Neptune have been called the “ice giants” for decades. But in new research, that nickname might be more a misnomer than anything. A study by the lead researchers astrophysicists Luca Morf ...

Scientists discover water that's solid and liquid. Superionic ice found in lab could explain Uranus and Neptune's bizarre ...

Models for the interior structures of the ice-giant planets Uranus and Neptune have two distinct, intermediate layers: an upper, water-rich convecting layer where disorganized magnetic fields are ...

Venture to the outer edges of the solar system where decades-long missions push the limits of human engineering. From ...

Uranus and Neptune may soon lose their reputation as the "boring" planets of the solar system. Long overshadowed by the grandeur of Jupiter and Saturn, scientists now believe that beneath their thick, ...

A study suggests the ice giants Uranus and Neptune aren't quite as watery as previously thought. They may also contain huge amounts of frozen methane, potentially solving the puzzle of how they formed ...

A team of researchers is challenging our understanding of the Solar System planets interior. The composition of Uranus and Neptune, the two outer most planets, might be more rocky and less icy than ...

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 ...

Astronomers may now understand why the similar planets Uranus and Neptune are different colors. Using observations from the Gemini North telescope, the NASA Infrared Telescope Facility, and the Hubble ...
