Scientists have found evidence of plate tectonics on Jupiter's moon Europa. This conceptual illustration of the subduction process (where one plate is forced under another) shows how a cold, brittle, outer portion of Europa's 20-30 kilometer-thick (roughly 10-20 mile) ice shell moved into the warmer shell interior and was ultimately subsumed. A low-relief subsumption band was created at the surface in the overriding plate, alongside which cryolavas may have erupted.

Cassini spied just as many regular, faint clumps in Saturn's narrow F ring, like those pictured here, as Voyager did, but it saw hardly any of the long, bright clumps that were common in Voyager images.

Map of membrane fluctuations in a normal red blood cell, on average up to 50 nanometers. Measuring these fluctuations over time, researchers found that the membranes stiffen.

This image depicts an illustration of helices.

Concept art of a molybdenum disulfide field-effect transistor based biosensor demonstrated by UCSB researchers with ability to detect ultra-low (femtomolar) concentrations with high sensitivity that is 74-fold higher than that of graphene FET biosensors.

Artist's concept of comet C/2013 A1 Siding Spring. On Oct. 19, the comet will have a very close pass at Mars, just 82,000 miles (132,000 kilometers) from the planet.

Three panels illustrate the condition of Efimov states (3-atom stable states). The upper, bell-shaped surface represents the probability density for each of the three geometries, while the gray surface represents the strength of the van der Waals force for that geometry. Left panel: the three interacting atoms lie in an equilateral triangle formation. Middle panel: two of the atoms are rather closer together than to the third atom. Right panel: the geometry of the middle panel but with the atoms lying farther apart from each other. The dimples in the probability density surface reflect the more complicated interaction when two of the atoms are close together.
