Jupiter moons

An artist's impression shows the internal structure of Jupiter's moon Io. Data from NASA's Juno spacecraft indicate that Io does not have a shallow global magma ocean, and is consistent with a mostly solid mantle (shown in green), with significant molten material (yellow and orange), above a liquid core (red/black).

Europa Clipper uses Mars' gravity to accelerate its way to Jupiter's mysterious moon

  • No comments
NASA's Europa Clipper probe has performed a gravity maneuver around Mars on its way to Jupiter's moon Europa, to investigate whether it might be home to extraterrestrial life.
SwRI is studying how Saturn's largest moon maintains its dense atmosphere. Scientists think Titan's core is covered in layers of ice and a subsurface liquid ocean. New experiments show that nitrogen and methane gases produced by organic matter in the core seep to the surface, regularly renewing the atmosphere. Credit: Southwest Research Institute

This composite image shows suspicious jets of water vapor erupting at the 7 o'clock position outside the boundary of Jupiter's moon Europa. The streams, imaged by NASA's Hubble Space Telescope's Imaging Spectrometer camera, were seen in silhouette as the moon passed in front of Jupiter. The Hubble data were collected on January 26, 2014. The image of Europa superimposed on the Hubble data consists of data from the Galileo Voyager missions Credit: NASA/ESA/W. Sparks (STScI)/USGS Astrogeology Science Center

NASA scientists conducted an experiment simulating the conditions on the icy moons Europa of Jupiter and Enceladus of Shabati and came to the conclusion that if there is life on them you don't need to dig deep to find at least their remains
This illustration shows charged particles from Jupiter hitting the face of Europa, separating icy water molecules into hydrogen and oxygen molecules. The scientists believe that some of these newly formed oxygen gases can move into the moon's subsurface ocean, as the circled figure shows. Credit: NASA/JPL-Caltech/SWRI/PU

Imaging of the Cassini spacecraft passing through the water jets of the moon Enceladus. The close flyby she made through the jets in 2015 allowed her to detect molecular hydrogen in the water jets and strengthen the possibility that the environment in the sub-glacial ocean from which the jets emanate supports the existence of life.
