Dynamics of Ocean Worlds Likely Controlled by Their Rotation

by Morgan Rehnberg 9 May 20229 May 2022

New simulations suggest that subsurface oceans on icy moons with small natural Rossby numbers may be dominated by rotational effects.

On Thin Ice: Tiger Stripes on Enceladus

by Nola Taylor Tillman 11 November 202029 September 2021

Saturn’s moon Enceladus boasts fierce tiger stripes around its south pole, a mystery that has long puzzled scientists. New research explores the stripes by examining how the moon’s ice breaks.

Electron Density near Enceladus Shows Orbital Variation

by Morgan Rehnberg 24 June 202029 September 2021

The electron density peaks well after the activity of the moon’s distinctive south polar ice plume reaches its maximum, but the cause of the lag remains puzzling.

Where Are the Electrical Currents in the Enceladus Plume?

by Mark Zastrow 7 July 20172 February 2022

A plume of water ice that escapes Saturn’s moon Enceladus should be coursing with electrical currents, but data are mixed. Now simulations suggest that a sticky dust cloud may shield signals.
