This image of Saturn's moon Titan from the Synthetic Aperture Radar instrument on the Cassini spacecraft shows the southwestern area of a feature called Xanadu (bottom right of the image). The area is bright because it reflects the radio wavelengths used to make this radar images. The image was taken on April 30, 2006.

Xanadu is one of the most prominent features on Titan and was first seen in ground-based observations. The origin of Xanadu is still unknown, but this radar image reveals details previously unseen, such as numerous curvy features that may indicate fluid flows. Linear dark streaks visible in radar-dark areas are dune fields, also seen in previous radar images.
Near the centre of the image is a prominent circular feature, named Guabonito, about 90 kilometres in diameter. It might be an impact crater or a cryovolcanic caldera. If this is an impact structure, the absence of an ejecta blanket suggests that the feature has been highly eroded, like some impact structures on Earth, or has been buried by the dune fields. Other radar-bright areas (top left and top right) appear to be topographically high and might act as obstacles, diverting the dunes around them.

The complex and dynamic atmosphere of Titan displays multiple haze layers near the north pole in this view, which also provides an excellent look at the detached stratospheric haze layer that surrounds the moon at lower latitudes.

North on Titan (5,150 kilometres across) is up and rotated 20 degrees to the left.

The image was taken with the Cassini spacecraft narrow-angle camera on March 16, 2006, using a filter sensitive to wavelengths of ultraviolet light centred at 338 nanometers. The image was obtained at a distance of approximately 1.2 million kilometres from Titan and at a Sun-Titan-spacecraft, or phase, angle of 68 degrees. Image scale is 7 kilometres per pixel.

This composite of 24 images from the Cassini spacecraft shows multiple layers in Titan's stratospheric haze. The most prominent layer is located about 500 kilometres above the surface and is seen at all latitudes, encircling the moon. The material in this layer is probably a condensed substance, possibly water ice.

Several other layers are most apparent in the north polar hood (at top), but this view also shows some at other latitudes. The mechanisms that produce these layers are not understood, but waves in the atmosphere are thought to play a significant role.
The images in this composite were taken over a period of 23 minutes. The images were processed to enhance fine detail and then were combined to create this view.
North on Titan is up.
The images were taken in visible light with the narrow-angle camera on Jan. 27, 2006 at a distance of approximately 2.3 million kilometres from Titan and at a Sun-Titan-spacecraft, or phase, angle of 155 degrees. Image scale is 13 kilometres per pixel.
