Mission Could Lasso Amino Acids from the Icy Plumes of Enceladus

by Isabel Swafford 13 December 202213 December 2022

If geysers from Saturn’s moon Enceladus contain amino acids, new research shows that a spacecraft could collect them with signatures of possible life preserved.

Dynamics of Ocean Worlds Likely Controlled by Their Rotation

by Morgan Rehnberg 9 May 202227 July 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

Nola Taylor Redd, Science Writer by Nola Taylor Tillman 11 November 20208 September 2022

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 202010 February 2023

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.

The Freshest Mineral Water in the Solar System

by A. Dombard 24 March 202022 December 2021

The water-rich plumes erupting from Saturn’s moon Enceladus show the chemical signs of water-rock interactions deep within the moon, further implicating Enceladus as a potential habitat for life.

Where Are the Electrical Currents in the Enceladus Plume?

by Mark Zastrow 7 July 201715 March 2023

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.
