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]
The rotation of Jupiter's polar atmosphere is about five minutes longer than that of the equatorial atmosphere. [135] The planet is an oblate spheroid, meaning that the diameter across its equator is longer than the diameter measured between its poles . [ 85 ]
Latitudinal pressure gradients established from measurements taken by Voyager IRIS were sufficient to produce super-rotation of the atmosphere. [4] Stratospheric zonal winds on Titan were observed on the order of 100-200 m s −1, [5] faster than the highest zonal winds on Earth at ~60-70 m s −1. Questions on the effect of obliquity in super ...
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 ...
These figures should be compared with the temperature and density of Earth's atmosphere plotted at NRLMSISE-00, which shows the air density dropping from 1200 g/m 3 at sea level to 0.125 g/m 3 at 70 km, a factor of 9600, indicating an average scale height of 70 / ln(9600) = 7.64 km, consistent with the indicated average air temperature over ...
Astronomers used the James Webb Space Telescope to newly detect a high-speed jet stream over the equator of Jupiter. Webb telescope spots never-before-seen feature in Jupiter’s atmosphere Skip ...
Investigators believe these tempests play an important role in regulating the Jovian atmosphere. Shallow lightning is seen by the Juno spacecraft emanating from clouds rich in ammonia.
The asteroid belt is located between Mars and Jupiter. It is made of thousands of rocky planetesimals from 1,000 kilometres (621 mi) to a few meters across. These are thought to be debris of the formation of the Solar System that could not form a planet due to Jupiter's gravity.
