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

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

Analysis of the Hubble imagery, combined with the data collected by Voyager 2, allowed for a more exact calculation of Uranus’ rotation speed. What they found did indeed fall within the original ...

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.

Astronomers have just discovered that Uranus takes one full rotation and a day in 28 seconds longer than first thought. The group employed observations taken by the NASA/ESA Hubble Space Telescope ...

Scientists reported Monday that observations by the Hubble Space Telescope have confirmed it takes Uranus 17 hours, 14 minutes and 52 seconds to complete a full rotation. That’s 28 seconds ...

For astronomers, determining a planet’s interior rotation rate is challenging and scientists can’t take direct measurements of Uranus. To try and solve this, the team on this study developed a ...

A day on Uranus just got slightly longer, thanks to more accurate measurements of its rotation period that should help scientists plan missions to probe the gas giant. Figuring out the rotation ...

A day at Uranus just got a little longer. Scientists reported Monday that observations by the Hubble Space Telescope have confirmed it takes Uranus 17 hours, 14 minutes and 52 seconds to complete ...
