Uranus' upper atmosphere


Radio emmessions discovered that Uranus actually possesses an magnetosphere.

Not only is their a Uranian magnetic field; it is intense with its axis tilted at a 60-degree angle to rotational axis.

The magnetic field source is unknown; the electrically conductive, super-pressurized ocean of water and ammonia once thought to lie between the core and the atmosphere now appears to be nonexistent.

Voyager measured thier being a magnetotail to at least 10 million kilometers (6.2 million miles) behind the planet.

Voyager 2 found radiation belts at Uranus. The radiation belts at Uranus appear to be dominated by hydrogen ions, without any evidence of heavier ions that might have been sputtered from the surfaces of the moons. Uranus's radiation belts are so intense that irradiation would quickly darken (within 100,000 years) any methane trapped in the icy surfaces of the inner moons and ring particles. This may have been what mad the darkened surfaces of the moons and ring particles.

Voyager found radio emissions from Uranus that helped narrow the planet's rate of rotation to about 17 hours, 14 minutes.
