Saturn’s Great Northern Storm churning through the atmosphere in the planet’s northern hemisphere overtakes itself as it encircles the planet in this true-color view from NASA’s Cassini spacecraft. This picture, captured on February 25, 2011, was taken about 12 weeks after the storm began, and the clouds by this time had formed a tail that wrapped around the gas giant.

The gas giant K2-132b expands as its host star evolves into a red giant. The energy from the host star is transferred from the planet’s surface to its deep interior, causing turbulence and deep mixing in the planetary atmosphere. The planet orbits its star every 9 days and is located about 2,000 light years away from us in the constellation Virgo. Upper left: schematic of the K2-132 system on the main sequence. Lower left: schematic of the K2-132 system now. The host star has become redder and larger, irradiating the planet more and thus causing it to expand.

This image from NASA’s Cassini spacecraft shows Saturn and its rings. Six of Saturn’s moons make a faint appearance in this image: the ice-covered moon Enceladus can be seen at the 1 o’clock position; directly below Enceladus, just outside the F ring (the thin, farthest ring from the planet seen in this image) lies the small moon Epimetheus; following the F ring clock-wise from Epimetheus, the next moon seen is Janus; at about the 4:30 position and outward from the F ring is Mimas; inward of Mimas and still at about the 4:30 position is the F-ring-disrupting moon, Pandora; moving around to the 10 o’clock position, just inside of the F ring, is the moon Prometheus.

$This false-color image demonstrates how use of special filters available on Curiosity’s Mastcam camera can reveal the presence of certain minerals in target rocks. It is a composite of images taken through three ‘science’ filters chosen for making hematite stand out as exaggerated purple. Mastcam’s narrow-band filters used for this view help to increase spectral contrast, making blues bluer and reds redder, particularly with the processing used to boost contrast in each of the component images of this composite. Fine-grained hematite preferentially absorbs sunlight around in the green portion of the spectrum around 527 nm. That gives it the purple look from a combination of red and blue light reflected by the hematite and reaching the camera through the other two filters. Bright lines within the rocks are fractures filled with calcium sulfate minerals. Image credit: NASA / JPL-Caltech / MSSS.$
