Here on the Gallery page you can find the very latest images, videos and products from the Cassini-Huygens mission to Saturn, including the spectacular launch, spacecraft assembly and the exciting trip to Saturn.
Full Description
This narrow angle field-of-view artist's rendering shows Titan's surface with Saturn dimly in the background through Titan's thick atmosphere of methane, ethane and (mostly) nitrogen. The Cassini spacecraft flys over the surface with its high-gain antenna pointed at the Huygens probe as it reaches the surface. Thin methane clouds dot the horizon, and a narrow methane spring or "methanefall" flows from the cliff at left and drifts mostly into vapor. Smooth ice features rise out of the methane/ethane lake, and crater walls can be seen far in the distance. By David Seal. (P-46508AC)

Spirit Rover on 'Husband Hill'
Description
Two Earth years ago, NASA's Mars Exploration Rover Spirit touched down in Gusev Crater. The rover marked its first Mars-year (687 Earth days) anniversary in November 2005. Shortly before Spirit's Martian anniversary, the Mars Orbiter Camera on NASA's Mars Global Surveyor acquired an image covering approximately 3 kilometers by 3 kilometers (1.9 miles by 1.9 miles) centered on the rover's location at that time in the "Columbia Hills.""Husband Hill," the tallest in the range, is just below the center of the image. The image has a resolution of about 50 centimeters (1.6 feet) per pixel. North is up, illumination is from the left. The location is near 14.8 degrees south latitude, 184.6 degrees west longitude. The image was acquired on Nov. 2, 2005. A white box indicates the location of an excerpted portion on which the location of Spirit on that date is marked. Dr. Timothy J. Parker of the Mars Exploration Rover team at the NASA's Jet Propulsion Laboratory, Pasadena, Calif., confirmed the location of the rover in the image. The region toward the bottom of the image shows the area where the rover is currently headed. The large dark patch and other similar dark patches are accumulations of windblown sand and granules.

Winter Night at Pic du Midi
Title
Winter Night at Pic du Midi
Explanation
This dreamlike [ http://picdumidi.org/ciel.html ] view looking south from the historic mountain top Pic du Midi Observatory [ http://www.world-heritage-tour.org/europe/fr/picDuMidi/ petitMatin.html ] combines moonlit domes, a winter night sky, and the snowy peaks of the French Pyrenees. Encroaching on the night [ http://www.globe.gov/GaN/ ], lights from the La Mongie ski resort illuminate the mountain slopes nearby while the glow along the distant horizon is from urban areas in southern France and Spain. The night sky features stars of the constellations Orion [ http://www.globe.gov/GaN/learn_orionsky.html ] and Gemini with a bright planet Mars [ http://antwrp.gsfc.nasa.gov/apod/ap071206.html ] very near the top edge, left of center. The three prominent domes visible (from left to right) house a 0.6 meter telescope reserved for amateur astronomers, a 1 meter telescope that was used to support the Apollo lunar landing [ http://antwrp.gsfc.nasa.gov/apod/ap070720.html ] missions, and the new, Sun-watching CLIMSO [ http://www.climso.fr/ ].
Aurora's Ring

Aurora's Ring
Explanation
Gusting solar winds [ http://antwrp.gsfc.nasa.gov/apod/ap000318.html ] and blasts [ http://antwrp.gsfc.nasa.gov/apod/ap020516.html ] of charged particles from the Sun made the early days of October rewarding ones for those anticipating auroras [ http://www.exploratorium.edu/learning_studio/ auroras/ ]. While out enjoying the stormy space weather [ http://www.spaceweather.com/ ] from Toemmeraas, Norway, Trygve Lindersen recorded this picturesque apparition [ http://science.nasa.gov/spaceweather/aurora/ gallery_01oct02_c.html ] of the northern lights with a digital camera on October 6. From this perspective, the curtains of green light formed a ring which seemed to hover, wraithlike [ http://www.pantheon.org/articles/a/aurora.html ], just above the foreground trees. But the ring of light was actually 100 kilometers or more above the trees [ http://antwrp.gsfc.nasa.gov/apod/ap010210.html ] and the greenish glow produced by oxygen molecules interacting with energetic electrons and fluorescing near the edge of space. After days of enchanting auroral displays [ http://science.nasa.gov/spaceweather/aurora/ gallery_01oct02.html ] on planet Earth, the solar activity which triggered October's geomagnetic storms [ http://spacescience.com/headlines/y2000/ast07 apr_2m.htm ] seems to have subsided ... for now.

Thousands of Coma Cluster Galaxies
Explanation
Almost every object in the above photograph is a galaxy [ http://antwrp.gsfc.nasa.gov/apod/ap950913.html ]. The Coma Cluster of galaxies pictured is a dense cluster containing many thousands of galaxies [ http://antwrp.gsfc.nasa.gov/apod/ap950912.html ]. Many of these galaxies [ ftp://crux.astr.ua.edu/web/goodies/data_resources/galaxies.text ] contain as many stars as our own Milky Way Galaxy [ http://antwrp.gsfc.nasa.gov/apod/ap950908.html ]. Although nearby when compared to most other clusters, light from the Coma Cluster still takes hundreds of millions of years to reach us. In fact, the Coma Cluster is so big it takes light millions of years just to go from one side to the other! This picture was created at the WWW site Skyview [ http://skview.gsfc.nasa.gov/ ], a "virtual observatory" where it is possible to view any part of the sky in wavelengths from radio to gamma-ray.
