Seen from our planet, the view of Saturns rings during equinox is extremely foreshortened and limited. But in orbit around Saturn, Cassini had no such problems. From 20 degrees above the ring plane, Cassinis wide angle camera shot 75 exposures in succession for this mosaic showing Saturn, its rings, and a few of its moons a day and a half after exact Saturn equinox, when the suns disk was exactly overhead at the planets equator.
This image of asteroid 2011 MD was taken by NASA's Spitzer Space Telescope in Feb. 2014, over a period of 20 hours. The long observation, taken in infrared light, was needed to pick up the faint signature of the small asteroid (center of frame).
Although Janus should be the least lonely of all moons - sharing its orbit with Epimetheus - it still spends most of its orbit far from other moons, alone in the vastness of space. Janus (111 miles or 179 kilometers across) and Epimetheus have the same average distance from Saturn, but they take turns being a little closer or a little farther.
NASA blows humanity's mind with beautiful pictures of Saturn
Curiosity's First Rock Star, Up-Close This close-up image shows the first target NASA's Curiosity rover aims to zap with its Chemistry and Camera (ChemCam) instrument. ChemCam will be firing a laser at this rock, provisionally named N165, and analyzing the glowing, ionized gas, called plasma, that the laser excites. The instrument will analyze that spark with a telescope and identify the chemical elements in the target.
