In the lights: Titan, Janus and the Rings...
|
Caption NASA:"Dazzling Titan glows with a 360° Sunset as light scatters through its very extended atmosphere. Some structure is visible in the hazes of the Northern Polar Hood.
To the left is Janus (181 Km, or 113 miles across), far off on the opposite side of the Ring-Plane. The Rings show their unlit side to Cassini, as the spacecraft viewed them from slightly above the ringplane.
A world with strikingly Earth-like physical processes, frigid Titan is Saturn's largest natural satellite, at 5.150 Km (about 3.200 miles) across. Titan's image is saturated (cosiddetto "effetto goccia di luce") at the 5 o'clock position.
The view was acquired in visible light with the Cassini spacecraft narrow-angle camera on June 2, 2006 at a distance of approx. 2,3 MKM (such as about 1,5 MMs) from Titan and at a Sun-Titan-spacecraft, or phase, angle of 163°. Cassini was 3,7 MKM (about 2,3 MMs) from Janus. Image scale is roughly 14 Km (about 9 miles) per pixel on Titan and approx. 22 Km (about 14 miles) on Janus".
