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.
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
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
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
