cwnl: Closest Dione Flyby Credit: NASA/JPL-Caltech/Space Science Institute Flying past Saturn’s moon Dione, Cassini captured this view which includes two smaller moons, Epimetheus and Prometheus, near the planet’s rings. The image was taken in visible light with Cassini’s narrow-angle camera during the spacecraft’s flyby of Dione on Dec. 12, 2011. This encounter was the spacecraft’s closest pass of the moon’s surface, but, because this flyby was intended primarily for other Cassini instruments, it did not yield Cassini’s best images of the moon. Higher resolution images were obtained during earlier flybys (At Carthage Linea).

cwnl: S is for Venus by Tunç Tezel Planet Venus traced out this S shape in Earth’s sky during 2004. Following the second planet from the Sun in a series of 29 images recorded from April 3rd through August 7th (top right to bottom left) of that year, astronomer Tunc Tezel constructed this composite illustrating the wandering planet’s path against the background stars.

scinerds: The largest storm seen on Saturn in more than 21 years has now been encircling the planet for a record-breaking 200 days. First appearing as a tiny blemish on Dec. 5, 2010, the storm is still going strong today, surpassing the ringed giant’s previous longest tempest, which lasted 150 days back in 1903. NASA’s Cassini spacecraft, in orbit around Saturn, has given astronomers a front-seat view of this enormous maelstrom and provided valuable data. From its humble beginnings, the storm has grown to engulf the entire area between Saturn’s 30th and 51st north latitudes. From north to south, the tempest stretches about 9,000 miles — greater than diameter of the Earth — and covers two billion square miles, or eight times the surface area of our planet. The storm marches through the planet’s atmosphere in the top right of this false-color mosaic from Cassini. Red and orange colors in this view indicate clouds that are deep in the atmosphere. Yellow and green colors, most noticeable along the top edge of the view, indicate intermediate clouds. White and blue indicate high clouds and haze. The rings appear as a thin horizontal line of bright blue. Image: NASA/JPL-Caltech/Space Science Institute (via WIRED)
