The researchers found the windy layers of Uranus and Neptune occupy the outermost 0.15 and 0.2 percent of their masses, respectively, suggesting that shallow processes drive those winds, such as ...

For comparison, Neptune is about 30,600 miles (49,250 km) in diameter, while Uranus is about 31,500 miles (50,700 km) wide. These findings help reveal how these winds originate, researchers said.

These are no mere zephyrs—jets on Neptune and Uranus can blast at roughly 1,000 mph, compared with Earth’s weaker winds of about 65 to 225 mph.

Instead, the team used deep circulation theories to predict what the gravitational fields of Neptune and Uranus should look like. And unlike the turbulent jet streams there, Hubbard said the winds ...

The weather forecast for Uranus and Neptune has been the same since the discovery of strong atmospheric winds in the 1980s by the Voyager II spacecraft. But now a team of Israeli and American ...

Similar to the gas giant planets Jupiter and Saturn, their smaller cousins, Uranus and Neptune, have long been known to harbor swirling clouds and violent winds churning up their atmospheres.

The icy giant worlds Uranus and Neptune are the least studied planets in the Solar System. Of all the space probes, only Voyager 2 visited them, and their great distance from the Sun (and therefore ...

These are no mere zephyrs -- jets on Neptune and Uranus can blast at roughly 1,000 mph, compared with Earth’s weaker winds of about 65 to 225 mph.

Kaspi and his colleagues focused on Uranus and Neptune, which are both "ice giants" — massive planets with icy atmospheres. The winds of Uranus can blow clouds up to 560 miles per hour (900 ...
