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

When NASA's Voyager 2 spacecraft made its way to outer regions of the solar system in the late 80's, it noticed something odd. Both of the ice giant planets, Uranus and Neptune, lacked what's known as a "dipole magnetic field." This was in stark contrast to our own rocky world, as well as the two gas giants Jupitar and Saturn.

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

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.

A recent study revealed surprising findings about Uranus and Neptune, which are often overlooked because of their dull appearance compared to other planets.The study published in the Proceedings of the National Academy of Sciences revealed

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

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.
