Relationship of the atmosphere and ionosphere. The ionosphere (/ aɪ ˈ ɒ n ə ˌ s f ɪər /) [1] [2] is the ionized part of the upper atmosphere of Earth, from about 48 km (30 mi) to 965 km (600 mi) above sea level, [3] a region that includes the thermosphere and parts of the mesosphere and exosphere. The ionosphere is ionized by solar ...
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 ]
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.

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 ...
Astronomers know of more than 400 volcanoes strewn across the surface of Io. Io is the most volcanically-active body in the Solar System apart from the Earth. Volcanos on Jupiter’s moon are ...
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 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 ]
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 ...
