Hubble's data points to a slow inward drift of dust from Uranus' distant irregular moons, which orbit between 2.5 to 13 million miles (4 to 20 million kilometers) from the planet.
Moons of Uranus surprise scientists in Hubble study by Space Telescope Science Institute edited by Stephanie Baum, reviewed by Robert Egan Editors' notes ...
A new study revealed Uranus’s structure as a planet changed and brightened significantly over the past 20 years. The study, performed by researchers from the University of Arizona and the ...
Uranus' hidden secrets revealed by a stellar eclipse A stellar occultation is when a distant star is eclipsed by an orbiting celestial body, such as a planet, which blocks the starlight.
The upshot is that we now know that a day on Uranus takes 17 hours, 14 minutes, and 52 seconds, or 28 seconds longer than the best previous estimate made by NASA’s Voyager 2 during its 1986 flyby.
Like the sun’s other giant worlds, Uranus (seen in this 1986 photo from the Voyager 2 spacecraft) radiates more energy than the sun gives it, though not nearly as strongly as its massive peers do.
Prepare for some big changes. On Jan. 30, Uranus will go direct in the sign of Taurus at 23 degrees, ending a five-month-long retrograde period that started on Sept. 1, 2024.
These findings cast doubt on earlier hypotheses and raise the possibility that Uranus and Neptune are home to a dynamic system of storms and atmospheric currents. Similar to Jupiter and Saturn, the ...
The proposed mission, known as Uranus Orbiter and Probe (UOP), would conduct a multiyear orbital tour to yield knowledge of ice giants in general and the Uranus system in particular, doing so ...
A pale blue-green enigma, the planet Uranus has long fascinated astronomers precisely because of its extreme distance, some 1.6 billion miles (2.6 billion km) from Earth. While it is comparatively ...
Scientists have found that a "rare intense wind event" during NASA's Voyager 2 flyby of Uranus in 1986 may have seriously messed with our understanding of the planet. And yes, we admit, the jokes ...
Voyager 2's visit to Uranus may have left us with the complete wrong impression of the ice giant for nearly 40 years, according to a new study.
