A planetary scientist proposes that the interiors of Uranus and Neptune are layered, with deep oceans of water above compressed carbon, nitrogen and hydrogen.

A scientist simulated the contents of the ice giant worlds, and found that a fluid layer may explain each planet’s strange magnetic field.

A new study found that vast oceans could be on Uranus and Neptune. Astrophysicist Adam Frank joins Chris Jansing to share his expertise.

Dramatic theories have been proposed to explain the mysterious interiors of Uranus and Neptune, the ice giants of our solar system.

According to Militzer, Earth, which has a neat, bar-magnet-like magnetic field generated by its molten iron core, Uranus and Neptune's magnetic fields are a mess, discovered to be disorganized during NASA’s Voyager 2 flybys in the late 1980s. That chaotic structure pointed to something unusual inside the planets.

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 unmixed,

We might finally understand what’s going on inside Uranus and Neptune, and the answer is pretty surprising: They may each contain an ocean of water. “We didn’t really know anything before,” about their interiors,

Uranus and Neptune were only visited once by human spacecraft when Voyager 2 passed by them almost 40 years ago. During those visits, scientists measured peculiar magnetic fields unlike those seen around other planets.
