Radiation forces on small particles in the solar system
TL;DR: In this paper, an expression for the effects of radiation pressure and Poynting-Robertson drag on small, spherical particles using the energy and momentum transformation laws of special relativity is derived.

TL;DR: Cassini has identified a geologically active province at the south pole of Saturn's moon Enceladus in images acquired by the Imaging Science Subsystem (ISS), this region is circumscribed by a chain of folded ridges and troughs at ∼55°S latitude as mentioned in this paper.
Selective reduction of disulfides by tris(2-carboxyethyl) phosphine
TL;DR: Tris(2-carboxyethyl) phosphine (TCEP) is a reagent for disulfide reduction in water at pH 4.5 that preferentially reduces more strained disulfides, in accordance with the usual mechanism postulated for reduction by phosphines in water.

TL;DR: High-resolution Galileo spacecraft images of Europa are presented, in which evidence for mobile ‘icebergs’ is found and the detailed morphology of the terrain strongly supports the presence of liquid water at shallow depths below the surface, either today or at some time in the past.

Enceladus's measured physical libration requires a global subsurface ocean
Peter C. Thomas,Radwan Tajeddine,Matthew S. Tiscareno,Matthew S. Tiscareno,Joseph A. Burns,J. Joseph,Thomas J. Loredo,Paul Helfenstein,Carolyn C. Porco +8 more
TL;DR: In this paper, the authors used measurements of control points across the surface of Enceladus accumulated over seven years of spacecraft observations to determine the satellite's precise rotation state, finding a forced physical libration of 0.120 ± 0.014° (2σ).
