Iapetus by Saturn Shine
Description Iapetus by Saturn Shine
Full Description European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging team is based at the Space Science Institute, Boulder, Colo.

Credit: NASA/JPL/Space Science Institute, This almost surreal view of Iapetus was acquired by Cassini about 10 minutes after the spacecraft's closest approach to the icy moon during a close flyby on New Year's Eve 2004. The image shows Iapetus' surface illuminated by reflected light from Saturn (not by the Sun) and is the highest resolution view acquired to date of this part of Iapetus' surface. Compared to the approximately one second exposure times used for imaging Iapetus' sunlit side, this view required a very long exposure time of 82 seconds. Cassini was designed to pivot while moving in order to keep its cameras and other remote sensing instruments pointed `on target' with great precision. Consequently, despite the large relative speed between Iapetus and the spacecraft during this long exposure -- about 2 kilometers per second or almost 4,500 miles per hour at closest approach -- the image of the moon's surface is un-smeared (although the background stars are smeared). This image reveals a heavily cratered surface and shows the boundary between Iapetus' bright trailing hemisphere and Cassini Regio -- a large, dark region that covers the leading hemisphere of the moon¿s surface. Some of the dark material appears to have collected inside the rim of a large impact structure about 250 kilometers across (155 miles) that lies just beyond the edge of the dark region (seen here near the right of the image). NASA's Voyager images (see PIA02268) this feature appeared as a dark 'moat' and had been hypothesized to be an impact structure. The recent images from Cassini confirm an impact origin for this feature. In contrast, the origin of the dark material is currently unknown and the recent images have sparked exciting debates among Cassini imaging scientists. Some characteristics of the dark region revealed in this and other images taken during the encounter suggest that dark material from elsewhere in the Saturnian system -- perhaps the result of an impact on another nearby moon -- has coated this side of Iapetus with a relatively thin layer. However, an internal origin for the material has not been ruled out and, if correct, may be related to the long equatorial ridge discovered in Cassini images to span Cassini Regio. Regardless of its origins, the dark material appears to lie on top of other geologic features seen on Iapetus thus far, implying that the event which formed the dark coating occurred later in Iapetus' history. A closer encounter with this moon later in the Cassini mission (September 2007) may reveal more detail and help answer the question of the origin and age of the dark material on Iapetus. The image was obtained in visible light with the Cassini spacecraft narrow angle camera on Dec. 31, 2004, at a distance of about 123,370 kilometers (76,659 miles) from Iapetus. The image scale is 730 meters (2,395 feet) per pixel. The image has been contrast enhanced to aid visibility of surface features. The Cassini-Huygens mission is a cooperative project of NASA, the

Description Exploring the Wetlands of Titan
Full Description Cassini peers through the murky orange haze of Titan to spy what are believed to be bodies of liquid hydrocarbons, two of them as large as seas on Earth, near the moon's north pole. This movie blends a near natural-color view and an infrared glimpse of Titan's surface obtained by the visual cameras, followed by a transition to imagery collected by the radar instrument aboard Cassini, for a dramatic reveal of the north pole of Saturn's largest moon. As the movie zooms in on the north pole, the most readily visible bodies are outlined in blue. The largest of these, on the left, is as big as the Caspian Sea on Earth, the next largest, on the right, is about the size of Lake Superior. When compared to the surface area of Titan however (which is six times smaller than Earth's), these bodies are equivalent in size to the Bay of Bengal and Timor Sea, respectively. Geographically speaking, they are more like seas. The movie continues with a gradual transition to a polar map of the radar imagery taken so far by Cassini of the north polar region. It is clear that one of the radar swaths has intersected a small upper bay of the largest sea, and has almost entirely imaged the second one. The extreme darkness of these regions in the radar data argues strongly for the presence of liquid hydrocarbons, such as methane and ethane, which remain liquid at Titan's frigid temperature of minus 180 degrees Celsius (minus 288 degrees Fahrenheit). See Titan (T25) Viewed by Cassini's Radar - Feb. 22, 2007. The movie continues with a pan across the pole and the radar imagery that has uncovered a multitude of much smaller lakes. Features of strikingly similar morphology to these dark northern seas and smaller lakes were first discovered in Cassini Imaging Science Subsystem images in June 2005, at Titan's south pole (see Land of Lakes?). The lake-like shoreline of the largest of these, called Ontario Lacus, its size (about the size of Lake Victoria), and its proximity to the south pole where the largest field of clouds yet seen on Titan had been observed, earned it the reputation as the best candidate for a body of liquid hydrocarbons on Titan up until that point, though the case for liquids was weak. When adjusted for the size of Titan, Ontario Lacus is equivalent in size to the Black Sea. Now, by inference, scientists are more confident that it, and the smaller features that dot the south pole, are also likely open bodies of liquid, and in aggregate make up a southern wetlands on Titan, similar to the one observed in the north polar movie. The images used to make this movie were taken with the Cassini spacecraft narrow-angle camera on Feb. 25, 2007, at a distance of approximately 1.3 million kilometers (800,000 miles) from Titan. The infrared images were taken with a special filter centered at 938 nanometers that provides the cameras' best view of Titan's surface features. This view was then composited with images taken at 619, 568 and 440 nanometers to, create a near natural color appearance. The radar data were acquired in synthetic aperture radar mode.

Hubert Curien
Description Hubert Curien
Full Description Hubert Curien was born on 30 October 1924 in the Vosges region of eastern France. While a student, he enlisted in the French resistance and was commended for bravery in action. He entered the Ecole Normale Supérieure in Paris and went on to pursue a research career in crystallography, joining the Sorbonne Mineralogy Laboratory. He was always keen to encourage collaboration between mineralogists and physicists. He was appointed lecturer at the University of Paris in 1949, obtained his PhD in 1951, and became professeur in 1956. From 1968 onwards, he continued with his teaching career at the 'Pierre et Marie Curie/Paris VI' University, which he left only in 1994, despite all his political duties. Aside from his scientific career, Hubert Curien is known mostly for his managerial and political responsibilities, pursued with commitment, efficiency and vision both in France and in Europe. He left his mark on an impressive number of scientific institutions. From 1966 to 1969, he was Scientific Director for Physics at the CNRS, France's scientific research centre, becoming its Director General in 1969. In 1973, he was given responsibility for reorganising research in France. From 1976 to 1984, he was President of the French space agency (CNES), and from 1984 to1993, served as Minister of Research and Space under four different governments. From 1981 to 1984, he was Chairman of the ESA Council, and he is now still remembered ¿ among his many achievements ¿ as one of the fathers of the Ariane programme and as a promoter of a Europe united through science. From 1994 to 1996, he also headed the European Organization for Nuclear Research (CERN), and in 1993, was elected to the French Academy of Science. For his work, Hubert Curien received the highest distinctions and awards. He was known for his great intelligence and managerial and political abilities, but also for his simplicity, modesty, sense of humour and willingness to listen to others. He died on 6 February 2005, and is survived by his wife, Perrine, and their sons, Nicolas, Christophe and Pierre-Louis. *Credits:* ESA

Huygens Landing Site
Description Huygens landing site
Full Description This image provides a comparison between the Huygens landing site on Titan as viewed by the Cassini Imaging Science Subsystem (ISS) and the NACO/SDI instrument mounted on the 8-meter Yepun telescope of the VLT (Very Large Telescope) station, in Chile. From the two images it is possible to see a high consistency between the two measurements. The Cassini image - taken in the near-infrared (938 nanometers)- shows the Huygens landing site map wrapped around Titan, rotated to the same position as the January 2005 NACO/SDI observations. The colored lines outline the regions that were imaged by Cassini at different resolutions. The lower-resolution imaging sequences are outlined in blue. Other areas have been specifically targeted to build moderate and high-resolution mosaics of surface features. These include the site where the Huygens probe has touched down on Jan. 14, 2005 (marked with the yellow X), and located at a latitude of 10.3° south and a longitude of 192.32° west (or 167.7° east). The landing site is located on the boundary between the bright region called Adiri and the dark one called Shangri-la. The red color on the NACO/SDI image corresponds to an atmospheric filter at 1.625 micron, while the blue color corresponds to a filter for the surface at 1.600 and 1.575 micron. *Credits:* NASA/JPL/Cassini-ISS/Space Science Institute and ESO/NACO-SDI/VLT

Titan 'T28' Mosaic
Description Titan 'T28' Mosaic
Full Description Bright and dark terrains on Titan's trailing hemisphere are revealed by Cassini's Imaging Science Subsystem in this mosaic of images taken during the T28 flyby in April 2007. The region shown in this image, centered on the northern part of Titan's trailing hemisphere (near 31.2 degrees North, 220.7 degrees West), had only been seen at very low resolution until February 2007, when Cassini flew over this area for the first time. This mosaic consists of images taken during one of a series of flybys in early 2007 designed to study this long unavailable part of Titan (5,150 kilometers, or 3,200 miles across). Several intriguing surface features can be seen in this mosaic that warrant further study. Along the top of the mosaic is a series of dark lineaments, or linear features, that stand out against the blandness of the northern, mid-latitude terrain. These features were also observed by the RADAR instrument in December 2006 and represent an area of potential future co-analysis for the RADAR and camera teams. Another such region is the large bright area known as Adiri at bottom center, also imaged by RADAR in October 2005. The mosaic shows a number of dark areas within Adiri that line up with small dune fields observed by RADAR. A portion of the dark terrain surrounding Adiri was also observed in 2005 by RADAR, and likewise was found to consist of large stretches of longitudinal dune fields --further supporting the correlation between equatorial dark regions and dune "seas." To the east of Adiri is a dark spot surrounded by a ring of bright material, which may be associated with an impact crater similar to Sinlap, discovered earlier in the Cassini mission (see Titan Mosaic - East of Xanadu). This mosaic consists of 29 separate frames using a total of 116 images. Each frame consists of three images, taken using a filter sensitive to near-infrared light centered at 938 nanometers, allowing for observations of Titan's surface and lower atmosphere, added together. An image taken using a filter sensitive to visible light centered at 619 nanometers was then subtracted from the product, effectively removing the lower atmosphere contribution to the brightness values in the image, increasing image contrast and improving the visibility of surface features. This process is also intended to reduce noise, but some camera artifacts still remain, such as a dark ring caused by dust in the camera system near the bottom right of each frame. For a wide angle view taken during this Titan encounter, see Titan 'T28' View. The images used for this mosaic were taken on April 11, 2007 from distances ranging from 106,000 to 180,000 kilometers (66,000 to 112,000 miles). This mosaic is in an orthographic projection with a pixel scale of 1.5 kilometers (0.9 miles) per pixel, although the size of resolvable features is likely several times larger, due to atmospheric scattering. An orthographic view is most like the view seen by a distant observer looking through a, telescope.

Wisps on Dione
Description Wisps on Dione
Full Description The Cassini spacecraft spies bright fractures in the icy crust of Dione. These bright "linea" cover the moon's trailing hemisphere and were imaged by Cassini at high resolution in 2005 (see At Carthage Linea ). This view looks toward the northern hemisphere on Dione's anti-Saturn side. North on Dione (1,126 kilometers, or 700 miles across) is up and rotated 33 degrees to the right. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on May 1, 2007 at a distance of approximately 1.8 million kilometers (1.1 million miles) from Dione and at a Sun-Dione-spacecraft, or phase, angle of 60 degrees.

Description Organics Sprinkled on Hyperion
Full Description Hyperion, the eighth largest of Saturn's nearly 60 known moons, is covered in craters and landslides. Sprinkled over the icy surface is a thin layer of organic dust, which has somehow been concentrated in the bottoms of some of the craters, forming a reddish black deposit. This new color map shows the composition of a portion of Hyperion's surface determined with the Visual and Infrared Mapping Spectrometer aboard the Cassini spacecraft. The new composition map is overlaid onto a previously released Cassini image of Hyperion, taken with the Imaging Science Subsystem (see Cosmic Blasting Zone). Blue shows the maximum exposure of frozen water, red denotes carbon dioxide ice ("dry ice"), magenta indicates regions of water plus carbon dioxide, yellow is a mix of carbon dioxide and an unidentified material. Discovered in 1848, Hyperion held its secrets until the Cassini spacecraft flew close in September 2005, revealing its icy and organic composition. Hyperion is irregular in shape, tumbles chaotically, and takes 21 days to orbit Saturn. It is 300 kilometers (180 miles) in its longest dimension.

LORRI Takes an Even Closer L …
title LORRI Takes an Even Closer Look at the Little Red Spot
date 02.26.2007
description LORRI took this mosaic 9½ hours -- or not quite one Jupiter rotation period -- after snapping its previous images of the Little Red Spot on Feb 26, 2007 (see PIA09294), at a longer range of 3.5 million kilometers (2.2 million miles) and at a lower resolution of 17 kilometers (10.5 miles) per pixel. The new mosaic was obtained with the Little Red Spot closer to the center of the visible disk of Jupiter, so there is less foreshortening and better illumination. The Little Red Spot is an Earth-sized storm on Jupiter that changed its color from white to red in 2005. Swimming to the east, its clouds rotate counterclockwise (or in the anticyclonic direction), meaning that it is a high-pressure region. In that sense, the Little Red Spot is the opposite of a hurricane on Earth, which is a low-pressure region - and it is of course much larger than any hurricane on Earth. Scientists don't know exactly how or why the storm turned red -- though they speculate that the change could stem from a surge of exotic compounds from deep within Jupiter, caused by an intensification of the storm system. In particular, sulfur-bearing cloud droplets might have been propelled about 50 kilometers into the upper level of ammonia clouds, where brighter sunlight bathing the cloud tops released the red-hued sulfur embedded in the droplets - causing the storm to turn red. A similar mechanism has been proposed for the Little Red Spot's "big brother," the Great Red Spot, a massive energetic storm system that has existed for centuries. The smaller, brighter oval to the south of the Little Red Spot is another storm moving more rapidly to the east, as can be seen by comparing the previous mosaic to the newer one. Any feature that moved by as much as 100 pixels between the earlier mosaic and the new one -- as many features have done -- has shifted at an average relative speed faster than 95 miles per hour, indicating hurricane force winds. The awesome violence of the storms in Jupiter's atmosphere contrasts with the serene isolation of New Horizons' LORRI, snapping pictures from millions of miles away. "The new images are further proof that LORRI is one of the best imagers ever flown on a planetary mission," says Dr. Andy Cheng, the LORRI principal investigator from the Applied Physics Laboratory, "and more delights are yet to come.

General Information What is an American Astronomical Society Meeting release? A major news announcement issued at an American Astronomical Society meeting, the premier astronomy conference. Using NASA's Hubble Space Telescope and the W.M. Keck Observatory, Kameula, Hawaii, astronomers have learned that the gaseous outflow from one of the brightest super-sized stars in the sky is more complex than originally thought. The outbursts are from VY Canis Majoris, a red supergiant star that is also classified as a hypergiant because of its very high luminosity. The eruptions have formed loops, arcs, and knots of material moving at various speeds and in many different directions. The star has had many outbursts over the past 1,000 years as it nears the end of its life. Read more: * The Full Story [ http://hubblesite.org/newscenter/archive/releases/2007/03/full/ ]

General Information What is Hubble Heritage? A monthly showcase of new and archival Hubble images. Go to the Heritage site. This NASA Hubble Space Telescope image shows the diverse collection of galaxies in a galaxy cluster called Abell S0740, located more than 450 million light-years away in the constellation Centaurus. The giant elliptical galaxy ESO 325-G004 looms large at the cluster's center. This galaxy is as massive as 100 billion suns. Hubble resolves thousands of globular star clusters orbiting ESO 325-G004. Globular clusters are compact groups of hundreds of thousands of stars that are gravitationally bound together. At the galaxy's distance they appear as pinpoints of light contained within the diffuse halo. Other elliptical and spiral galaxies appear in the image. The photo was made from images taken using Hubble's Advanced Camera for Surveys in January 2005 and February 2006.
