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. [28]
Three systems are used as frames of reference for tracking planetary rotation, particularly when graphing the motion of atmospheric features. System I applies to latitudes from 7° N to 7° S; its period is the planet's shortest, at 9h 50 m 30.0s. System II applies at latitudes north and south of these; its period is 9h 55 m 40.6s. [136]
Time-lapse sequence from the approach of Voyager 1 to Jupiter in 1979, showing the motion of atmospheric bands, and the circulation of the Great Red Spot. The black spots that appear are shadows cast by Jupiter's moons. Jupiter's Great Red Spot rotates counterclockwise, with a period of about 4.5 Earth days, [24] or 11
In contrast to the strongly seasonal atmosphere of Uranus, which can be featureless for long periods of time, Neptune's atmosphere has active and consistently visible weather patterns. At the time of the Voyager 2 flyby in 1989, the planet's southern hemisphere had a Great Dark Spot comparable to the Great Red Spot on Jupiter.
The Juno spacecraft has been orbiting Jupiter since 2016 and it has already provided us with a wealth of information about the gas giant. Today, four Nature papers describe new observations about ...
The Great Red Spot is a massive vortex within Jupiter’s atmosphere that is about 10,159 miles (16,350 kilometers) wide, which is similar to Earth’s diameter, according to NASA. The storm ...

Jupiter was known to astronomers of ancient times. [1] The Romans named it after their god Jupiter . [ 2 ] When viewed from Earth , Jupiter can reach an apparent magnitude of −2.94, bright enough for its reflected light to cast shadows, [ 3 ] and making it on average the third-brightest object in the night sky after the Moon and Venus .
