NASA: Cassini Spacecrafy Checking in on Saturn - The Boston Globe - Part 2 - Links

The shadow of Saturn's largest moon darkens a huge portion of the gas giant planet. Titan (5,150 km, or 3,200 mi across) is not pictured here, but its shadow is elongated across Saturn's upper atmosphere. The image was taken with the Cassini spacecraft wide-angle camera on November 7th, 2009 using a spectral filter sensitive to wavelengths of near-infrared light centered at 752 nanometers. The view was obtained at a distance of approximately 2.1 million km (1.3 million mi) from Saturn. (NASA/JPL/SSI)

This image shows the first flash of sunlight reflected off a lake on Saturn's moon Titan, detected on on July 8, 2009. The glint off a mirror-like surface is known as a specular reflection, and it confirmed the presence of liquid in the moon's northern hemisphere, where lakes are more numerous and larger than those in the southern hemisphere. Cassini scientists were able to correlate the reflection to the southern shoreline of a Titan lake called Kraken Mare. The sprawling Kraken Mare covers about 400,000 sq km (150,000 sq mi).

Saturn's rings, made dark in part as the planet casts its shadow across them, cut a striking figure before Saturn's largest moon, Titan. The night side of the planet is to the left, out of the frame of the image. Illuminated Titan can be seen above, below and through gaps in the rings. The moon Mimas (396 km, 246 mi across) is near the bottom of the image. Atlas (30 km, 19 mi across) can barely be detected near the thin F ring just above the center right of the image.

This image of the surface of Saturn's moon Dione was taken by Cassini on April 7, 2010. The view was acquired at a distance of approximately 2,500 km (1,600 mi) from Dione. Image scale is 15 meters (50 feet) per pixel. (NASA/JPL/SSI)


Seen on May 18, 2010, Enceladus partially blocks Cassini's view of a brightly lit segment of Saturn's rings. (NASA/JPL/SSI)


Saturn's moon Dione passes in front of the larger moon Titan, as seen from Cassini. The image was taken with the Cassini spacecraft narrow-angle camera on March 12, 2010. The view was obtained at a distance of approximately 2.2 million km (1.4 million mi) from Dione and 3.6 million km (2.2 million mi) from Titan. (NASA/JPL/SSI)


A large cloud formation swirls through the high northern latitudes of Saturn near the top of this Cassini image taken on February 14th, 2010. The view was obtained at a distance of approximately 523,000 km (325,000 mi) from Saturn. Image scale is 28 km (17 mi) per pixel. (NASA/JPL/SSI)


The moon Prometheus creates an intricate pattern of perturbation in Saturn's F ring while the moon Daphnis disturbs the A ring in this image taken after the planet's August 2009 equinox. Prometheus (86 km, or 53 mi across) can be seen between the thin F ring and the A ring in the middle left of the image. The gravity of potato-shaped Prometheus periodically creates streamer-channels in the F ring. Near the bottom of the image, Daphnis (8 km, or 5 mi across) can be seen creating edge waves in the Keeler Gap of the A ring. The moon has an inclined orbit and its gravitational pull perturbs the orbits of the particles of the A ring, forming the Keeler Gap's edge, and sculpts the edge into waves having both horizontal (radial) and out-of-plane components. Image acquired on Aug. 22, 2009 with a scale of 12 km (7 mi) per pixel. (NASA/JPL/SSI)


Titan's golden, smog-like atmosphere and complex layered hazes appear to Cassini as a luminous ring around the planet-sized moon. Images taken using red, blue and green spectral filters were combined to create this color view. Six images - two sets of three colors - were combined to create the mosaic. The images were acquired with the Cassini wide-angle camera on Oct. 12, 2009 at a distance of 145,000 km (90,000 mi) from Titan. (NASA/JPL/SSI)


An aurora, shining high above the northern part of Saturn, moves from the night side to the day side of the planet in this movie recorded by Cassini. These observations, taken over four days, represent the first visible-light video of Saturn's auroras. They show tall auroral curtains, rapidly changing over time when viewed at the limb, or edge, of the planet's northern hemisphere. The sequence of images also reveals that Saturn's auroral curtains reach heights of more than 1,200 km (746 mi) above the planet's limb. These are the tallest known "northern lights" in the solar system. Each image was obtained with a two- or three-minute exposure, taken in visible light with the Cassini spacecraft's narrow-angle camera from October 5th to 8th 2009. (NASA/JPL/SSI)
