NASA's Cassini spacecraft returned an image of Saturn's moon Tethys that highlights a particularly large basin on its surface.

According to Space.com, NASA called the basin Odysseus and measured it to be 280 miles across, almost the equivalent to half Tethys' diameter. Also notable about Odysseus is that it is considerably brighter than the rest of the moon's surface.

"With the expanded range of colors visible to Cassini's cameras, differences in materials and their textures become apparent that are subtle or unseen in natural color views. Here, the giant impact basin Odysseus on Saturn's moon Tethys stands out brightly from the rest of the illuminated icy crescent," NASA said in a statement. "This distinct coloration may result from differences in either the composition or structure of the terrain exposed by the giant impact. Odysseus (280 miles, or 450 kilometers, across) is one of the largest impact craters on Saturn's icy moons, and may have significantly altered the geologic history of Tethys."

Most of NASA's focus has understandably been on New Horizons and its first ever flyby of Pluto. But thanks to spacecraft like Cassini, NASA became the first space agency to ever explore each planet originally included in the solar system (since Pluto's status as a dwarf is still debated).

Saturn has 62 known moons and Tethys is the fifth largest behind Titan, Rhea, Iapetus and Dione, Space.com noted. Cassini, a collaborative effort with the European and Italian Space Agencies, will continue to examine the unique Saturn system until its planned dive into the ringed planet's atmosphere in Sept. 2017.
