Unusual greenish clouds in equatorial region of planet Jupiter. Source: Lunar Captures
Green clouds on Jupiter. Really not a usual color for clouds neither on Jovian like gas giants nor on terrestrial planets!
A crazy idea: Maybe it´s chlorophyll?! Free-floating colonies of algae-like lifeforms in temperated Jovian atmosphere layers performing a sort of photosynthesis.
Jupiter ist a veritable weather planet. Jetstreams, high and low pressure systems, clouds of all kinds, thunderstorms, rain and snow (ammonia but also water in temperated layers).
