Astronomers reveal surprising findings The post Uranus’ Day is Longer: Astronomers Reveal Surprising Findings appeared first ...

By using a new technique, they found that Uranus completes a full rotation in 17 hours, 14 minutes and 52 seconds. That’s 28 seconds longer than the previous estimate in 1986.

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

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

The planet’s elusive aurorae are much colder than expected, which is how they evaded detection for so long.

Hubble space telescope discovers Uranus' day is 28 seconds longer than previously estimated. New findings improve tracking of Uranus' magnetic poles. If you've been wondering how long the day on ...

Space weather creates the Northern Lights on Earth, and more recently, aurora lights on Uranus helped Nasa’s Hubble Space Telescope measure the planet’s interior rotation rate, changing what ...
