Tethys in eclipse
Our moon is not the only natural satellite to experience eclipses. Pictured here is Saturn’s moon Tethys in partial eclipse. “While in eclipse the moon is illuminated by feeble ringshine reflected from the planet's night side and by sunlight scattered through the rings,” according to NASA. It was taken on Sept. 25, 2008, by the Cassini spacecraft. Tethys is a small moon about 1,066 kilometers (662 miles) in diameter. It was first discovered by astronomer Giovanni Cassini in 1684 and is named for the Greek titan Tethys, daughter of Uranus and Gaea, sister to Kronus and wife of Oceanus.
