Volcano World Update: Lava Lakes On Io
Editor’s note: Is there life on Io? To be certain, Io is a radiation-drenched lava world, yes. But life on Earth manages to thrive in some rather absurdly extreme volcanic […]

Energy And Temperature Dependencies For Electron-induced Sputtering From H2O-ice: Implications For The Icy Galilean Moons
To better assess the role that electrons play in exosphere production on icy-rich bodies, we measured the total and O2 sputtering yields from H2O-ice for electrons with energies between 0.75 […]
