Based on 20 years of observations by NASA’s Hubble Space Telescope, new research sheds light on one of the solar system’s ...

Uranus just got a little more time on its hands. A fresh analysis of a decade's worth of Hubble Space Telescope observations shows Uranus takes 17 hours, 14 minutes and 52 seconds to complete a ...

The research builds on existing information about Uranus, like the fact that the planet is composed mainly of water and ...

while its rotation axis was 98 degrees offset. These extreme offsets mean that Uranus effectively rotates “lying down” compared with Earth, while its magnetic poles trace a large circle as the ...

This makes calculating the length of a Uranian day hard enough, but it's further complicated by Uranus being tilted at 98 degrees on its axis ... a marker to track the rotation of Uranus with ...

The long-term data on the planet's auroral emissions enabled the researchers to track the positions of the planet's magnetic poles and, by extension, its inner rotation rate. Aurora on Uranus in ...

Once every 24 hours, Earth completes one rotation on its axis, marking one day on our planet ... You may like Scientists finally know how long a day on Uranus is Earth: Facts about the Blue ...

This approach can now be used to determine the rotation rate of any celestial object with a magnetic field and auroras — including exoplanets. Uranus just got a little more time on its hands.

A French-led team studied a decade's worth of aurora observations at the ice giant to track its magnetic poles. That long-term tracking provided a more precise rotation period for Uranus ...
