Jupiter’s icy moon Europa produces plenty of oxygen every day, according to new findings based on data from NASA’s Juno spacecraft. The moon has long been of interest to astrobiologists because of the possibility that life could exist in its subsurface ocean.The Epitome of 14 inch Gaming | Asus ROG Zephyrus G14 ReviewThe research, published this week in Nature Astronomy, focused on data from Juno’s Jovian Auroral Distributions Experiment, or JADE. The scientists estimated oxygen production from the moon based on the…

NASA’s Juno spacecraft captured new images of Jupiter’s moon Io during its latest flyby, coming within an eerily close distance of the most volcanically active world in the solar system for a second time in less than two months. The close encounter also shows what appears to be a pair of plumes erupting from the moon’s surface.

Titan orbits Saturn. Below Titan are the shadows cast by Saturn’s rings. Credit: NASA/JPL-Caltech/Space Science InstituteScientists have discovered strike-slip faults on the icy moons of our solar system, similar to those seen at the San Andreas fault in California. These faults occur when fault walls slide sideways past each other. New research from the University of Hawai‘i at Mānoa, led by earth and space scientists, has explored and explained the origins of these geological features on Titan, Saturn’s largest moon,…

Jupiter's largest moon, Ganymede, features a surprisingly strong magnetic field for its size. Tidal effects from Jupiter continually stretch and squeeze the moon, keeping its core warm and driving the magnetic field. But the exact geological processes occurring within the core are not fully understood.Now, a new experimental study has put one of the leading models of core dynamics to the test: the formation of crystalized 'iron snow'.The iron snow theory is like a geological 'weather model' for a planetary core: it…

The mutilated surface of Jupiter’s moon Io was revealed in great detail by the Juno spacecraft, which has been exploring the Jovian system since 2016 and recently pulled off the closest flyby of the volcanic world.Let’s Eat a Chocolate Xbox ControllerNASA’s Jupiter probe had its close encounter with Io on Saturday, December 30, flying at a distance of 930 miles (1,500 kilometers) away from its hellish surface. This marked not only the closest flyby of Io by Juno, but by any spacecraft in the past 20 years, according to…

NASA’s curious Jupiter probe is getting chummier with the planet’s most erratic moon, Io. The Juno spacecraft will carry out the closest encounter any mission has had with the volcanic moon in over 20 years, collecting valuable clues about its mysterious activity.Freewrite Alpha Is the Little, Expensive E-Typewriter That CouldJuno will make its flyby of Io on Saturday, December 30, coming within 930 miles (1,500 kilometers) from the hellish surface of the Jovian moon, according to NASA. The spacecraft has observed Io…

Two new studies associated with the James Webb Space Telescope’s Early Release Science program have been published, and both have to do with Jupiter’s moons, namely Ganymede and Io.Webb Telescope Images the Pillars of CreationThe first study, led by astronomer Samantha Trumbo from Cornell University and published in Science Advances, presents a fascinating first—the unprecedented detection of hydrogen peroxide on Ganymede. The second study, published in JGR: Planets, reveals another neat finding—sulfurous fumes,…

The JUICE spacecraft captured its first ultraviolet views of the cosmos, revealing a beautiful streak of the Milky Way littered with shining stars fromthe southern sky. It’s not the most spectacular image, but it signals operational progress. Teyonah Parris and John Boyega on Working With Jamie Foxx | io9 InterviewJUICE’s Ultraviolet Spectrograph (UVS) instrument recently sprung into action, collecting its first set of data that was later imaged by the mission team. “On June 20, we opened the UVS aperture door to collect…

Just a week ago, the European Space Agency's first ever Jupiter mission took off from ELA-3 in Europe's Spaceport in Kourou, French Guiana. The mission, named Jupiter Icy Moons Explorer or JUICE, is being led by the European Space Agency (ESA). The spacecraft will study three of Jupiter's Galilean moons — Ganymede, Callisto, and Europa — in search of water and signs of life on them. The spacecraft shot into space on the Ariane 5 rocket. Interestingly, the spacecraft took 'selfies' while leaving Earth behind.ESA released…

A European spacecraft rocketed away Friday on a decadelong quest to explore Jupiter and three of its icy moons that could hold buried oceans.The journey began with a perfect morning liftoff by Europe's Ariane rocket from French Guiana on the coast of South America. But there were some tense minutes later as controllers awaited signals from the spacecraft. When contact finally was confirmed close to an hour into the flight, Mission Control in Germany declared: “The spacecraft is alive!” It will take the robotic explorer,…
