Helium Rains Inside Saturn, Jupiter And Other Jovian Planets, Research Suggests

Models of how Saturn and Jupiter formed may soon take on a different look. By determining the properties of hydrogen-helium mixtures at the millions of atmospheres of pressure present in the interior of Saturn and Jupiter, physicists have determined the temperature at a given pressure when helium becomes insoluble in dense metallic hydrogen.

Is Jupiter's Core Dissolving?

Academics / General Science : Science & Health from Newser (3 years ago)

Jupiter may be the largest planet in our solar system, but what if its massive core is actually dissolving? Jupiter's core of iron, rock, and ice is suspended in a sea of hydrogen and helium, under pressure 40 million times greater ... Read Post

Saturn and Jupiter: X-ray laser spies deep into giant gas planets

Academics / General Science : Science Daily (11 months ago)

Using DESY's X-ray laser FLASH, researchers took a sneak peek deep into the lower atmospheric layers of giant gas planets such as Jupiter or Saturn. The observations reveal how liquid hydrogen becomes a plasma, providing information... Read Post

Researchers Probe Mysteries of Jupiter and Saturn Atmospheres

Academics / General Science : The Daily Galaxy (11 months ago)

The atmosphere of gas giants consists mainly of hydrogen, which is the most abundant chemical element in the universe. “We have very little experimental knowledge about the hydrogen in the interior of such planets,” says Ulf Zastrau... Read Post
