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.

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.

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.
