Long hidden behind a thick veil of haze, Titan, the only known moon with an atmosphere, is ready for its close-up. This visit by the Cassini spacecraft may settle intense speculation about whether this moon of Saturn harbors oceans of liquid methane and ethane beneath its coat of clouds. Encircled in purple stratospheric haze, Titan appears as a softly glowing sphere in this colorized image taken one day after Cassini's first flyby of that moon.

This image reveals Titan's bright "continent-sized" terrain known as Xanadu. The surface is seen at a higher contrast than in previously released imaging science subsystem images due to a lower phase angle (Sun-Titan-Cassini angle), which minimizes scattering by the haze.

Early analysis of images and other data captured during last night's close flyby of Saturn's moon Titan by the Cassini spacecraft reveals greater surface detail than ever before and shows that Titan has lost much of its original atmosphere over time. This image taken by Cassini's visual and infrared mapping spectrometer clearly shows surface features on Titan.

The first radar images of Saturn's moon Titan show a very complex geological surface that may be relatively young. Previously, Titan's surface was hidden behind a veil of thick haze. Brighter areas may correspond to rougher terrains and darker areas are thought to be smoother.

The day of descent
4 November 2004
When ESA’s Huygens probe plunges into the atmosphere of Saturn’s largest moon,
Titan, on 14 January 2005, telescopes on Earth will be watching the remote
world.
Observations of Titan from Earth will help to understand the global condition
of the atmosphere, while Huygens is passing through a tiny section of it. As
Huygens drifts down, its instruments and cameras will be collecting vital
information about the atmosphere and surface.
The Cassini mothership will be listening, so that it can later transmit the
results to Earth but, while Cassini is pointing its high-gain antenna at
Huygens, it cannot watch Titan with its cameras. So telescopes on Earth will
try to do the job.
The telescopes located around the Pacific Ocean will be used because Titan
will be in view from these areas at the time of the Huygens descent. An
observation from space, by the NASA/ESA Hubble Space Telescope, is also
planned.
The most exciting possibility is that the observations may show a tiny, bright
speck at the moment Huygens enters the atmosphere.

Saturn's moon Titan shows a sharp contrast between its smooth and rough edges in a new false-color radar image. Titan's surface lies beneath a thick coat of hazy clouds, but Cassini's radar instrument can peer through to show finer surface features. Scientists have added color to emphasize finer details on Titan, as shown in the image.

A strikingly bright feature that is consistent with an active geology has been seen in one of Cassini's first radar images of Saturn's moon Titan. There are many possibilities for what it is but one of the leading candidates is that it may be a 'cryovolcanic' flow or 'ice volcano'.

This view of Saturn's second-largest moon, Rhea, shows some of the large craters that cover its surface. There is a bright feature near the moon's right limb, possibly a large, rayed crater or bright icy material exposed by internal processes. The image has been magnified by a factor of four and contrast-enhanced to aid visibility.

This Cassini image shows a bright storm that appeared in mid-September at the latitude of one of the rare westward jets on Saturn. This latitude band has come to be called "Storm Alley" by Cassini imaging scientists because of the large amount of activity seen there during 2004. The mottling in the image is an artifact.

Two large craters and hints of several smaller ones are visible in this Cassini image of Saturn's icy moon Tethys. The image has been contrast-enhanced and magnified by a factor of four to aid visibility.

This Cassini view shows a bright storm that appeared in Saturn's southern hemisphere in mid-September and continued to evolve afterward. This type of storm is a good candidate source for lightning because of its sudden appearance and high level of activity. Lightning can be detected by Cassini's cameras when the spacecraft is on Saturn's night side, and by the radio and plasma wave detector on either the day or night side. Several dark ovals to the left and right of this storm mark the sites of other storms in this turbulent westward-flowing region of the atmosphere. The icy moon Enceladus is visible near the bottom of the image.
