The last couple of months have just been packed with a slew of weird surface formations in our own solar system.  Here is one of the latest:

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 color features on Saturn’s moons to be revealed by Cassini’s cameras.

Images taken using clear, green, infrared and ultraviolet spectral filters were combined to create the enhanced-color views, which highlight subtle color differences across the icy moon’s surface at wavelengths not visible to human eyes.

Let’s find out more about this mysterious phenomena and check out a video of Tethy’s surface on page 2
