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.

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.
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.
Researchers used Webb’s Near-Infrared Camera, or NIRCam, to take a series of images of Jupiter 10 hours apart, applying four different filters to detect changes in the planet’s atmosphere.
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 ...
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.
The Great Red Spot, or GRS, is an anticyclone, or a large circulation of winds in Jupiter’s atmosphere that rotates around a central area of high pressure along the planet’s southern ...
The atmosphere of Io is the extremely thin blanket of gases surrounding Jupiter's third largest moon Io. The atmosphere is primarily composed of sulfur dioxide ( SO 2 ), along with sulfur monoxide ( SO ), sodium chloride ( NaCl ), and monoatomic sulfur and oxygen . [ 1 ]
