In Depth | Jupiter – NASA Solar System Exploration
The composition of Jupiter is similar to that of the Sun – mostly hydrogen and helium. Deep in the atmosphere, pressure and temperature increase, compressing the hydrogen gas into a liquid. This gives Jupiter the largest ocean in the solar system – an ocean made of hydrogen instead of water.
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.

2000年12月28日 · Jupiter's atmosphere. It is sensitive to the amount of cloud and haze down to the pressure of the water cloud, which lies at a depth where pressure is about 6 times the atmospheric pressure at sea level on the Earth). Light in the strongest methane band is absorbed at high altitude and is
In Depth | Saturn – NASA Solar System Exploration
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.
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).

2025年1月9日 · NASA’s real-time science encyclopedia of deep space exploration. Our scientists and far-ranging robots explore the wild frontiers of our solar system.
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.
In Depth | Europa – NASA Solar System Exploration
Europa orbits Jupiter every 3.5 days and is locked by gravity to Jupiter, so the same hemisphere of the moon always faces the planet. Jupiter takes about 4,333 Earth days (or about 12 Earth years) to orbit the Sun (a Jovian year).
10 Need-to-Know Things About Jupiter - NASA Solar System …
Jupiter orbits about 484 million miles (778 million kilometers) or 5.2 Astronomical Units (AU) from our Sun (Earth is one AU from the Sun).
