The atmosphere of Uranus is composted mainly of molecular hydrogen and helium. The third most abundant molecule after hydrogen and helium is methane (CH4). It’s the methane in Uranus’ atmosphere that absorbs the red spectrum visible light and gives it the blue-green color.
Beans, beans, the magical fruit.
The more you eat, the more you toot.
Dang.
The herds on Uranus must be massive to generate that much methane.
