NASA. An extraordinary view of the planet SATURN as seen by the CASSINI spacecraft while in the planet's shadow (the sun is behind the planet, shielding the cameras from direct sunlight). In addition to the visual splendor, this special viewing geometry at very high phase allows scientists to study phenomena in the rings and atmosphere that are difficult to see at lower phase. As images of this kind can only be taken when the sun is behind the planet, this beautiful view is all the more precious for its rarity. Two of Saturn's moons are also represented in this image: Enceladus and Tethys. Both appear on the left side of the planet, below the rings. Images taken with infrared, red and violet spectral filters have been combined to create this color-enhanced view. Vintage chromogenic print. References in the plate on the front. Legend on label on back. 50.4 x 50.4CM with margins.
