In Depth | Jupiter – NASA Solar System Exploration
Jupiter is the fifth planet from our Sun and is, by far, the largest planet in the solar system – more than twice as massive as all the other planets combined. Jupiter's stripes and swirls are actually cold, windy clouds of ammonia and water, floating in an atmosphere of hydrogen and helium.
Galileo Probe Science Results - NASA Solar System Exploration
The composition of Jupiter's atmosphere offered some surprises, according to project scientists. It contains significantly lower than expected levels of helium, neon, and certain heavy elements, such as carbon, oxygen and sulfur.
Saturn's Hidden Turbulence Revealed - NASA Solar System …
2013年9月16日 · Peering deeply into Saturn's placid-looking atmosphere with the radar/microwave radiometer aboard NASA's Cassini spacecraft has revealed a dynamic and in many places turbulent atmosphere that has more similarities with that of its sibling planet Jupiter than previously realized.
Jupiter Clouds in Depth - NASA Solar System Exploration
2000年12月28日 · Jupiter Clouds in Depth December 29, 2000 Images from NASA's Cassini spacecraft using three different filters reveal cloud structures and movements at different depths in the atmosphere around Jupiter's south pole.
NASA's Juno Mission Provides Infrared Tour of Jupiter's North Pole
2018年4月11日 · Infrared cameras are used to sense the temperature of Jupiter’s atmosphere and provide insight into how the powerful cyclones at Jupiter's poles work. In the animation, the yellow areas are warmer (or deeper into Jupiter’s atmosphere) and the dark areas are colder (or higher up in Jupiter’s atmosphere).

Like Jupiter, Saturn is made mostly of hydrogen and helium. At Saturn's center is a dense core of metals like iron and nickel surrounded by rocky material and other compounds solidified by intense pressure and heat.
Comet Freight Train to Collide with Jupiter - NASA Solar System …
As the comet string nears Jupiter, its associated dust coma will be bombarded by charged particles trapped in Jupiter's magnetosphere. Gas and dust ejected from the comet may be swept up by Jupiter's magnetic field, possibly causing large changes in the density and composition of Jupiter's aurora.

Jupiter’s large Galilean moons – Io, Europa, Ganymede, and Callisto – likely formed out of leftover material after Jupiter condensed from the initial cloud of gas and dust surrounding the sun, early in the history of the solar system.
CIRS Objectives and Plans at Jupiter - NASA Solar System …
2001年1月22日 · CIRS functions both as a remote-sensing assayer and thermometer. In the mid-infrared, CIRS measures the abundances and spatial distributions of various gases, including methane, acetylene, benzene, and other hydrocarbons, water, and carbon dioxide. The observed distribution will provide clues to the physical processes active in Jupiter's ...
