This newly released Cassini image shows Tethys dwarfed by Saturn and its rings.

Tethys, dwarfed by the scale of Saturn and its rings, appears as an elegant crescent in this image taken by NASA’s Cassini Spacecraft. Views like this are impossible from Earth, where we only see Saturn’s moons as (more or less) fully illuminated disks.

The region of Saturn seen at left is on the planet’s night side. Reflected light from the rings dimly illuminates the planet’s northern hemisphere.

This view looks toward the anti-Saturn side of Tethys. North on Tethys is up and rotated 24 degrees to the left. The image was taken in visible light with the Cassini spacecraft wide-angle camera on August 18, 2015.

The view was acquired at a distance of approximately 184,000 miles (296,000 kilometers) from Tethys. The image scale is 11 miles (18 kilometers) per pixel.

    Excellent crescent of Tethys illuminated by just reflection from Saturn’s ring speaks of the highly luminous cloud ring of Saturn in the sky which in turn is already lit by Sun’s glow. If such a luminous cloud were there for earth, no doubt, out nights should have been brightened by glow. Thank You.
