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.

MWR is also designed to detect the amount of water and ammonia deep inside Jupiter. [5] It should also be able to provide a temperature profile of atmosphere down to 200 bar (2901 psi). [5] Overall MWR is designed to look down as deep as roughly 1,000 atmospheres (or bar or kPa), which is about 342 miles (550 kilometers) down inside Jupiter.
Based on Jupiter's composition, researchers have made the case for an initial formation outside the molecular nitrogen (N 2) snow line, which is estimated at 20–30 AU (3.0–4.5 billion km; 1.9–2.8 billion mi) from the Sun, and possibly even outside the argon snow line, which may be as far as 40 AU (6.0 billion km; 3.7 billion mi).
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 ...
Now, they think they know just how old it is and how the cyclone formed in Jupiter’s atmosphere. Jupiter’s Great Red Spot is different from what an Italian astronomer observed in 1665 Skip to ...
Jupiter is covered with a cloud layer about 50 km deep. The clouds are composed of ammonia crystals and possibly ammonium hydrosulfide. The clouds are located in the tropopause and are arranged into bands of different latitudes, known as tropical regions. These are sub-divided into lighter-hued zones and darker belts.
NASA's Juno spacecraft captured this view of Jupiter during the mission's 54th close flyby of the giant planet Sept. 7, 2023.
The atmosphere has a mass of about 5.15 × 10 18 kg, [2] three quarters of which is within about 11 km (6.8 mi; 36,000 ft) of the surface. The atmosphere becomes thinner with increasing altitude, with no definite boundary between the atmosphere and outer space.
