- Jupiter's icy moon Europa displays many signs of activity, including its fractured crust and a dearth of impact craters, but plumes remain elusive. http://www.nasa.gov/jpl/signs-of-europa-plumes-remain-elusive-in-search-of-cassini-data/#.vjnxisvf9ed 6 comments space
- Astronomers have tracked two huge lava waves rolling around a volcanic crater the size of Wales on one of Jupiter’s many moons. Geological forces unleashed the waves on Io, where the most powerful active volcano in the solar system has produced an 8,301 square mile dent in the surface. https://www.theguardian.com/science/2017/may/10/lava-waves-size-wales-jupiter-moon-io 8 comments science
- The vast subterranean ocean of Europa, one of Jupiter’s many moons, contains carbon, one of the crucial ingredients for life, scientists have discovered. The observations indicate that carbon dioxide ice on the moon’s surface originated from the ocean that lies beneath a 10-mile thick crust of ice. https://www.science.org/doi/10.1126/science.adg4155 15 comments science
- Saturn’s rings are so much brighter than Jupiter's because they're made mostly of ice particles replenished by many small moons embedded in the rings. Jupiter’s dim, thin rings, by contrast, are made mostly of dust shed from a few small moons, and the large Galilean moons destroy any large rings. https://astronomy.com/news/2022/07/why-dont-jupiters-rings-look-like-saturns 14 comments space
- Dinosaur asteroid 'sent life to Mars': The asteroid that wiped out the dinosaurs may have catapulted life to Mars and the moons of Jupiter, US researchers say. They calculated how many Earth rocks big enough to shelter life were ejected by asteroids in the last 3.5bn years. http://www.bbc.co.uk/news/science-environment-25201572 22 comments science
