In 2005, NASA’s Cassini spacecraft observed a water-rich plume erupting from the south polar terrain of Enceladus, suggesting that this moon of Saturn possessed a subsurface ocean beneath its icy […]
Mars experienced widespread volcanism and tectonic activity 3 to 4 billion years ago, but it has been viewed as largely tectonically quiescent since then. From 2018 to 2022, NASA’s InSight […]
Hubble Space Telescope observations of Jupiter’s geologically active, icy moon Europa have shown the moon ejecting plumes of liquid water, but linking the plumes to specific surface features has remained […]
Saturn’s icy moon Enceladus harbors a big ocean of water beneath its icy crust, which is evident from erupted water plumes from Enceladus’ surface. The Ion and Neutral Mass Spectrometer (INMS) […]
https://acquisition.jpl.nasa.gov/bizops Recent Hubble Space Telescope (HST) detection of anomalous concentrations of hydrogen and oxygen at Europa could potentially be due to plumes, analogous to the well-characterized plume at Enceladus as observed by the […]
