The small Jupiter moon’s atmosphere undergoes a dramatic transformation when it passes into the gas giant’s shadow.
Jupiter’s moon Io is not only interesting in that it’s the most volcanic place in the solar system, it also has a seriously weird atmosphere that collapses and re-inflates as it passes into Jupiter’s shadow every single day.
As Io orbits Jupiter, the extreme Jovian tides warp the moon so much that huge quantities of energy are generated, causing molten rock from the moon’s interior to spew onto the surface, driving perpetual volcanic activity. Continue reading On Volcano Moon Io, it Snows Sulfur Every Day
Exotic “dark hydrogen” lurks within giant planets such as Saturn and Jupiter, a new study suggests.
This strange form of hydrogen likely lies between the gaseous hydrogen in the clouds of gas giants such as Saturn and Jupiter and the liquid-metal hydrogen found in these planets’ cores, according to the study. Continue reading Mysterious ‘Dark Hydrogen’ May Lurk Within Giant Planets
On July 4, 2016, the Juno probe is scheduled to reach Jupiter, and begin a campaign to get closer to the Jovian giant than any other spacecraft in history.
Including Juno, there have been nine space probes that have studied Jupiter up close. The first was Pioneer 10, which sailed past the striped giant in 1973. Here’s a rundown of those nine missions, and what they have accomplished. Continue reading Up Close and Personal with Jupiter: A History of 9 Space Probes
As excitement builds for NASA’s Juno mission that will enter Jupiter orbit this summer, and future missions that will investigate ice moon Europa’s life-supporting potential, new research into the strange qualities of the moon’s cracked crust could reveal some fascinating science about Europa’s sub-surface ocean. Continue reading Europa’s Deforming Ice Is a Surprising Heat Generator
New imagery of Jupiter from the Hubble Space Telescope has been released. The imagery includes new Jupiter maps and an Ultra HD animation. The two new global maps of Jupiter were made using Hubble’s Wide Field Camera 3. One of the global maps is pictured above. Continue reading New Hubble Jupiter Maps and Ultra HD Animation Released
