Unusual Red Arcs Spotted on Icy Saturn Moon

Like graffiti sprayed by an unknown artist, unexplained arc-shaped, reddish streaks are visible on the surface of Saturn's icy moon Tethys in new, enhanced-color images from NASA's Cassini spacecraft.
The red arcs are narrow, curved lines on the moon's surface, and are among the most unusual colour features on Saturn's moons to be revealed by Cassini's cameras.

Cassini Finds a Pac-Man thermal shape on Tethys

pia16198-640.jpg

Scientists with NASA's Cassini mission have spotted a second feature shaped like the 1980s video game icon in the Saturn system, this time on the moon Tethys. (The first was found on Mimas in 2010). The pattern appears in thermal data obtained by Cassini's composite infrared spectrometer, with warmer areas making up the Pac-Man shape.

Eclipsing Pulsar Promises Clues to Crushed Matter

NASA's Cassini spacecraft has returned Saturnian moon images from its flyby late last week, revealing light and dark contrasts worthy of chiaroscuro painters like Caravaggio.
The flyby on August 13 targeted the geyser moon Enceladus, but also brought Cassini close to two other moons--Tethys and Dione.
The raw images include the best ones to date of Penelope crater on the icy moon Tethys. Penelope crater, which is 150 kilometres wide, is the second-largest crater on Tethys.

This global map of Saturn's moon Tethys was created using images taken during Cassini spacecraft flybys.
The map is an equidistant (simple cylindrical) projection and has a scale of 293 meters per pixel at the equator in the full size version.

This image of Tethys was taken by the Cassini spacecraft on the 9th January, 2010, when it was approximately 662,431 kilometres away.
The image was taken using the CL1 and CL2 filters.

The image looks almost directly down at the south pole of Tethys and was taken in visible light with the Cassini spacecraft narrow-angle camera on May 18, 2008, when it was approximately 357,000 kilometres  from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 72 degrees.

The large crater Melanthius is seen above centre.
Image scale is 2 kilometres per pixel.

This image of the southernmost reaches of the great rift of Tethys - Ithaca Chasma - was taken in visible green light with the Cassini spacecraft narrow-angle camera on May 10, 2008, when it was approximately 183,000 kilometres away and at a Sun-Tethys-spacecraft angle of 73 degrees.

The view is centred on terrain at 43 degrees south latitude, 52 degrees west longitude. North on Tethys is up and rotated 28 degrees to the right.
