The composition of Jupiter's atmosphere is similar to that of the planet as a whole. [1] Jupiter's atmosphere is the most comprehensively understood of those of all the giant planets because it was observed directly by the Galileo atmospheric probe when it entered the Jovian atmosphere on December 7, 1995.

The Great Red Spot is a persistent high-pressure region in the atmosphere of Jupiter, producing an anticyclonic storm that is the largest in the Solar System. It is the most recognizable feature on Jupiter, owing to its red-orange color whose origin is still unknown.
Jupiter was the first of the Sun's planets to form, and its inward migration during the primordial phase of the Solar System affected much of the formation history of the other planets. Jupiter's atmosphere consists of 76% hydrogen and 24% helium by mass, with a denser interior.
Storms on Jupiter form ammonia-rich hail — called mushballs — in the atmosphere of the giant planet, new research reveals. Investigators believe these tempests play an important role in ...
Io (/ ˈ aɪ. oʊ /), or Jupiter I, is the innermost and second-smallest of the four Galilean moons of the planet Jupiter.Slightly larger than Earth's moon, Io is the fourth-largest moon in the Solar System, has the highest density of any moon, the strongest surface gravity of any moon, and the lowest amount of water by atomic ratio of any known astronomical object in the Solar System.
The atmosphere of Uranus is composed primarily of gas and various ices. It is about 83% hydrogen, 15% helium, 2% methane and traces of acetylene. Like Jupiter and Saturn, Uranus has a banded cloud layer, although this is not readily visible without enhancement of visual images of the planet.
It is the moon with the highest volcanic activity in the Solar System, as a result of the tidal forces from the planet and its oval orbit around it. Even so, the surface is still cold: -143 Cº. The atmosphere is 200 times lighter than Earth's atmosphere, the proximity of Jupiter gives a lot of radiation, and it is completely devoid of water.
The lunar atmosphere is extremely thin and technically classified as an exosphere, meaning atoms do not collide with each other because their numbers are so sparse, in contrast to Earth's thick ...
