Temperature profile of the Uranian troposphere and lower stratosphere. Cloud and haze layers are also indicated. The Uranian atmosphere can be divided into three main layers: the troposphere, between altitudes of −300 [a] and 50 km and pressures from 100 to 0.1 bar; the stratosphere, spanning altitudes between 50 and 4000 km and pressures between 0.1 and 10 −10 bar; and the thermosphere ...
Uranus is an oblate spheroid, which causes its visible area to become larger when viewed from the poles. This explains in part its brighter appearance at solstices. [16] Uranus is also known to exhibit strong zonal variations in albedo (see above). [10] For instance, the south polar region of Uranus is much brighter than the equatorial bands. [3]
No spacecraft other than Voyager 2 has flown by our seventh planet from the sun. Alone but certainly unique, Uranus rotates at a nearly 90-degree angle and is surrounded by 13 icy rings.
Neptune, which is Uranus's near twin in size and composition, radiates 2.61 times as much energy into space as it receives from the Sun, [23] but Uranus radiates hardly any excess heat at all. The total power radiated by Uranus in the far infrared (i.e. heat) part of the spectrum is 1.06 ± 0.08 times the solar energy absorbed in its atmosphere .
In 1986, Nasa’s Voyager 2 flew by the seventh planet in the Solar System, providing scientists with their first and only glimpse of Uranus, and shaping their understanding of it since.
Uranus is the butt of a lot of jokes, but scientists pronounce the name of our seventh planet differently than, say, most giggling middle-schoolers. You've been pronouncing 'Uranus' wrong your ...
At an extreme tilt, such as that of Uranus, the poles can receive similar annual surface insolation to the equator.) In particular, at Earth temperatures, and all else being equal, greater tilt warms the poles and thus reduces polar ice coverage, while lesser tilt cools the poles and thus increases polar ice coverage.
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 ...
