A day on Uranus is longer than previously known

An international team of astronauts has discovered new measurements of how long a day is on Uranus.

Surprise at the ice giant: The planet Uranus rotates more slowly than astronomers have figured out. Their analysis of images of the Hubble telescope from eleven years shows that the distant ice giant needs 17 hours, 14 minutes and 52 seconds for a rotation. This is 28 seconds more than assumed on the basis of decade-old data from the Voyager 2 spacecraft. The new value also explains some discrepancies in observations of the Uranus. For rock plan…

Hubble data finds Uranus' day is 28 seconds longer than scientists thought

Tapping more than a decade of Hubble Space Telescope observations, astronomers have determined Uranus’s rotation period with ultra-high accuracy — roughly 1,000 times greater than previous estimates — by tracking the planet’s unique ultraviolet aurorae. This new measurement refines the Uranian day to 17 hours, 14 minutes, and 52 seconds, establishing a vital baseline for… The post Hubble data reveals Uranus’ day is 28 seconds longer than scienti…

Astronomers Measure Rotation Rate of Uranus with Unprecedented Precision

The rotation period of Uranus was estimated to be 17.24 hours in 1986 from radio auroral measurements made by NASA’s Voyager 2 spacecraft. The post Astronomers Measure Rotation Rate of Uranus with Unprecedented Precision appeared first on Sci.News: Breaking Science News.

Have We Been to Uranus? We Asked a NASA Expert: Episode 56

2 min readPreparations for Next Moonwalk Simulations Underway (and Underwater) Have we ever been to Uranus? The answer is simple, yes, but only once. The Voyager II spacecraft flew by the planet Uranus back in 1986, during a golden era when the Voyager spacecraft explored all four giant planets of our solar system. It revealed an extreme world, a planet that had been bowled over onto its side by some extreme cataclysm early in the formation of …
