Extreme environments in a world of new extremes
Ecosphere, Volume 17, Issue 2, February 2026.Abstract Extreme environments, whether defined by climate, soils, or disturbance, at landscape or micro‐scales, are prevalent across Earth's surface and have long served as crucibles for ecological and evolutionary insights. Many foundational theories were developed in deserts, cliffs, ultramafic soils, and other harsh systems.

Enceladus’s Tidal Heating: A Simple Approach
The Planetary Science JournalSaturn’s moon Enceladus has a global ocean that is covered by an ice shell. The moon’s eccentric orbit forces the shell to librate, which distorts the shell and thereby generates heat.

A Search for Water Masers in the Saturnian System
, 2010 We searched for H2O 6(1,6)-5(2,3) maser emission at 22.235 GHz from several Saturnian satellites with the Nobeyama 45m radio telescope in May 2009. Observations were made for Titan, Hyperion, Enceladus and Atlas, for which Pogrebenko et al.

Electroanalysis, Volume 38, Issue 2, February 2026.Future in situ missions to ocean worlds of the outer solar system would benefit from the aqueous chemical measurements provided by ion‐selective electrodes (ISEs). Here, we verify the performance of ISEs after exposure to environments expected during outer Solar System missions, specifically near‐decade scale transit times, anhydrous conditions, low ...

Estimating the Initial Mass of the Gaia–Enceladus Dwarf Galaxy with a Chemical Evolution Model
The Astrophysical JournalThis work investigates the initial mass and chemical evolution history of the Gaia–Enceladus dwarf galaxy. We combine spectroscopic data from APOGEE with astrometric data from Gaia Data Release 3 to identify Gaia–Enceladus candidate stars via a machine ...

Enceladus's internal ocean and ice shell constrained from Cassini gravity, shape, and libration data
Geophysical Research Letters, 2016 The intense plume activity at the South Pole of Enceladus together with the recent detection of libration hints at an internal water ocean underneath the outer ice shell.

Pitch Angle Distributions of Energetic Electrons Near Ganymede: Galileo EPD Measurements
Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.Abstract Galileo flew‐by Ganymede six times between 1996 and 2000. The Energetic Particles Detector (EPD) performed energy resolved, directional electron measurements, and together with the magnetometer data, pitch angle distributions (PADs) could be derived.

Temporal Changes in Europa's Ice Shell Thickness: Insights From Models of Convection
Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.Abstract Europa is characterized by a thin ice Ih shell overlying a subsurface ocean and a large solid core. Estimates of the outer ice shell's thickness range from a few kilometers to several tens of kilometers, with strong implications for Europa's thermal and geological history.

Water Transport from Enceladus to the Rings
The Planetary Science JournalEnceladus continuously ejects approximately 300 kg s ^−1 of water vapor from its south polar regions, forming an extensive neutral gas torus around Saturn.
