and Neptune have distinctive hues. Researchers constructed a single atmospheric model that matches observations of both planets.....The model reveals that excess haze on Uranus accumulates in the planet’s stagnant, sluggish atmosphere, giving it a lighter hue than Neptune.
The planets Neptune and Uranus have much in common — they have similar
masses, sizes, and atmospheric compositions — yet their appearances are
notably different. At visible wavelengths Neptune has a distinctly bluer
color whereas Uranus is a pale shade of cyan.
New research suggests that a layer of concentrated haze that exists on
both planets is thicker on Uranus than a similar layer on Neptune and
‘whitens’ Uranus’s appearance more than Neptune’s.
If there were no haze in the atmospheres of Neptune and Uranus, both would appear almost equally blue.
--The team’s model consists of three layers of aerosols at different heights.
--The key layer that affects the colors is the middle layer, which is a
layer of haze particles (referred to in the paper as the Aerosol-2
layer) that is thicker on Uranus than on Neptune.
The team suspects that, on both planets, methane ice condenses onto the
particles in this layer, pulling the particles deeper into the
atmosphere in a shower of methane snow." SciTechDaily
