Scientists have found that Uranus emits its own internal heat, contradicting data from NASA's Voyager 2 probe nearly four decades ago.
Scientists find surprising evidence that space dust is shaping the surfaces of Uranus' largest moons.
NASA researchers got a rare chance to study Uranus' atmosphere and rings this month, when the ice giant passed between Earth and a distant star, creating a "stellar occultation."
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 full rotation — 28 seconds longer than the estimate provided by NASA's Voyager 2 spacecraft nearly 40 years ago.
