Straightening Out Uranus’s Magnetosphere

Damond Benningfield, Science Writer by Damond Benningfield 6 December 20246 December 2024

New analysis of Voyager 2 observations shows that the craft arrived amid gusty solar wind, muddying our ideas about the giant planet.

Studying the Mystery of Uranus’s Curiously Weak Radiation Belts

by Nathaniel Scharping 1 July 20241 July 2024

The belts may not be weak at all—instead, they may be simply changing speed thanks to the planet’s asymmetric magnetic field.

Uranus is a shiny blue-white orb, slightly off center in this image. Its rings are seen nearly face on, and six bright blue dots show the six brightest moons of the planet. There are several reddish galaxies in the background.

Uranus: Time to Boldly Go

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 25 September 202325 September 2023

Scientists say now is the time to unlock the secrets of Uranus and suggest a low-cost, low-risk way to do so.

A Mission to Uranus Could Help Find Planet 9

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 22 May 202322 May 2023

Narrowing down the search is essential for gaining time on a high-powered telescope that could spot the hypothesized planet directly.

What Surprises do the Icy Uranian Moons Hold?

by Kelsi Singer 22 February 202317 February 2023

With efforts ramping up to send a spacecraft back to the Uranian system, anticipation is increasing as to what geological surprises are hiding inside and on the surfaces of the icy Uranian moons.

A Unified Atmospheric Model for Uranus and Neptune

by Morgan Rehnberg 1 August 20221 August 2022

In a new model, three substantial atmospheric layers appear consistent between the ice giants.

The light green planet Uranus sits on a black background. One bright white and many faint white concentric rings encircle the planet face on, and many small white specks, its moons, are scattered across the image.

Can Uranus’s Rings Reveal the Planet’s Deepest Secrets?

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 17 December 202124 May 2023

Planetary rings can act as seismometers that respond to changes deep within a planet.

Do Uranus’s Moons Have Subsurface Oceans?

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 14 December 20203 November 2021

Scientists tested whether a classic technique could detect subsurface oceans on the moons of Uranus. In this scenario, the planet’s oddball magnetic field offers a big advantage.
