Pwyll and Manannán Craters as a Laboratory for Constraining Irradiation Timescales on Europa
We examine high spatial resolution Galileo/NIMS observations of the young (~1 My – 20 My) impact features, Pwyll and Manannán craters, on Europa’s trailing hemisphere in an effort to constrain […]

Juno Measures The Rate Of Oxygen Production At Europa
Scientists with NASA’s Juno mission to Jupiter have calculated the rate of oxygen being produced at the Jovian moon Europa to be substantially less than most previous studies.
