A new computational model suggests that Uranus' and Neptune's cores may be less icy than their "ice giant" nickname suggests.

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 ...

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 ...
