The upper atmosphere of Uranus is the source of the far ultraviolet (90–140 nm) emissions known as dayglow or electroglow, which, like the H 3 + IR radiation, emanates exclusively from the sunlit part of the planet.
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's atmosphere is remarkably bland in comparison to the other giant planets which it otherwise closely resembles. [1] [2] When Voyager 2 flew by Uranus in 1986, it observed a total of ten cloud features across the entire planet.
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 ...
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.
Uranus – seventh planet from the Sun. It has the third-largest planetary radius and fourth-largest planetary mass in the Solar System . Uranus is similar in composition to Neptune , and both have different bulk chemical composition from that of the larger gas giants Jupiter and Saturn .
A solar wind event squashed the protective bubble around Uranus just before Voyager 2 flew by the planet in 1986, shifting how astronomers understood the mysterious world.
The average temperature of the atmosphere of the planet is about 59 K (−214.2 °C). Surprisingly, the illuminated and dark poles, and most of the planet, show nearly the same temperature at the cloud tops. Voyager 2 found 10 new moons, bringing the total number to 15 at the time. Most of the new moons are small, with the largest measuring ...
