The atmosphere of Uranus is composed primarily of hydrogen and helium. At depth, it is significantly enriched in volatiles (dubbed "ices") such as water , ammonia , and methane . The opposite is true for the upper atmosphere, which contains very few gases heavier than hydrogen and helium due to its low temperature.
HST image of Uranus taken in 1998 showing clouds in the northern hemisphere The greenish color of Uranus's atmosphere is due to methane and high-altitude photochemical smog. Voyager 2 acquired this view of the seventh planet while departing the Uranian system in late January 1986. This image looks at Uranus approximately along its rotational pole.
Uranus's upper atmosphere imaged by HST during the Outer Planet Atmosphere Legacy (OPAL) observing program. [ 109 ] The middle layer of the Uranian atmosphere is the stratosphere , where temperature generally increases with altitude from 53 K (−220 °C; −364 °F) in the tropopause to between 800 and 850 K (527 and 577 °C; 980 and 1,070 °F ...
Uranus, blue-green in color due to the methane contained in an atmosphere comprised mostly of hydrogen and helium, has a diameter of about 31,500 miles (50,700 km). It is big enough to fit 63 ...
In addition to its somewhat awkward name, Uranus has also been called "the boring planet." At first glance it does look rather calm -- and, yes, even boring. Underneath its placid blue face, there ...
Both planets are actually a similar shade of pale, greenish blue, new research suggests
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.
NASA has just released new images of Uranus. Captured by JWST, the images show incredible details of the planet and its surrounding rings and moons. The James Webb Telescope Just Took a Truly ...
