For this reason, scientists often classify Uranus and Neptune as "ice giants" to distinguish them from the gas giants. Uranus's atmosphere is similar to Jupiter's and Saturn's in its primary composition of hydrogen and helium , but it contains more " ices " such as water, ammonia , and methane , along with traces of other hydrocarbons .
[16] [62] Discrete features were only once observed in Uranus's atmosphere before 1986. [12] [7] The most conspicuous features on Uranus observed by Voyager 2 were the dark low latitude region between −40° and −20° and bright southern polar cap. [62] The northern boundary of the cap was located at about −45° of latitude.

NASA’s Voyager 2 flyby in 1986 provided the only close-up look at Uranus. Nearly 40 years later, scientists are looking back at this data and finding out the visit happened during a strange ...
Uranus was the last giant planet without any known irregular moons until 1997, when astronomers using ground-based telescopes discovered Sycorax and Caliban. From 1999 to 2003, astronomers continued searching for irregular moons of Uranus using more powerful ground-based telescopes, resulting in the discovery of seven more Uranian irregular ...
Uranus is a beautiful, icy ringed world in the outer reaches of our solar system. It is among the coldest of all the planets. It is also tilted on its side compared to all the other worlds – as ...
