Astronomers have just revealed that a day on Uranus is longer than was previously thought, at 17 hours, 14 minutes and 52 ...

Observations of Jupiter show that ammonia is unevenly distributed in the upper atmosphere, against expectations of uniform mixing. Scientists found evidence for a complicated but apparently real ...

Imagine a Slushee composed of ammonia and water encased in a hard shell of water ice. Now picture these ice-encrusted ...

Uranus Findings Can Aid the Study of Exoplanets Now more than 30 years into its mission, the Hubble Space Telescope has ...

A new way to measure the length of Uranus’s day could also help determine the rotation rates of other celestial objects—including exoplanets ...

Uranus, the third-largest planet in our solar system ... wind event that colored scientists’ conclusions about the ice giant.

Uranus seemed like a fairly calm, blue-green planet. But new findings from Hubble paint a different picture of Uranus.

The detection of Neptune's auroras will help astronomers better understand how particles from the sun interact with its atmosphere, providing a new area of study about ice giant planets.

Because the ice giant takes just over 84 Earth years to complete one orbit around the sun, the researchers mainly got to observe the planet's northern spring as the sun moved from shining directly ...

The ice-giant planet Uranus, which travels around the sun tipped on its side, is a weird and mysterious world. Now, in an unprecedented study spanning two decades, researchers using NASA's Hubble ...

For the first time, the James Webb Space Telescope (JSWT) has revealed bright auroral activity on the planet Neptune. Capturing the auroral activity on the ice giant has been long in coming ...
