Title Dusty Death of a Massive Star
Description The supernova remnant1E0102.2-7219 (inset) sits next to the nebula N76 in a bright, star-forming region of the Small Magellanic Cloud, a satellite galaxy to our Milky Way galaxy located about 200,000 light-years from Earth. A supernova remnant is made up of the messy bits and pieces of a massive star that exploded, or went supernova. The image on the right shows glowing dust grains in three wavelengths of infrared radiation: 24 microns (red) measured by the multiband imaging photometer aboard NASA's Spitzer Space Telescope, and 8.0 microns (green) and 3.6 microns (blue) measured by Spitzer's infrared array camera. The red bubble is a dust envelope around the supernova remnant E0102, which is being heated by the shock wave created in the explosion of the remnant's massive progenitor star some 1,000 years ago. Most of the blue stars are in the Small Magellanic Cloud, though some are in our own galaxy. The close-up of E0102 on the left is a composite of the infrared observations by Spitzer (red), an optical image (0.5 microns) captured by NASA's Hubble Space Telescope (green), and X-ray measurements by NASA's Chandra X-ray Observatory (blue). The X-ray ring is generated when the reverse shock slams into stellar material that was expelled during the explosion.

Title Galactic Fossil Revealed in Infrared Light
Description This animation demonstrates the power of infrared light to see what visible light cannot -- a newfound bundle of stars called a globular cluster. The movie shifts from a visible-light image to a near-infrared image to a new mid-infrared image from NASA's Spitzer Space Telescope. The visible-light image is from the California Institute of Technology's Digitized Sky Survey and the near-infrared image is from the NASA-funded Two Micron All-Sky Survey (2MASS). Globular clusters date back to the birth of our galaxy, 13 or so billion years ago. There are about 150 clusters sprinkled around the core of the galaxy like seeds in a pumpkin. Astronomers use these galactic "fossils" as tools for studying the age and formation of the Milky Way. Most clusters orbit around the center of the galaxy well above its dust-enshrouded disc, or plane, while making brief, repeated passes through the plane that each last about a million years. Spitzer, with infrared eyes that can see into the dusty galactic plane, first spotted the newfound cluster during its current pass. Astronomers then searched for past references to the cluster and found only one undocumented image from the Two Micron All-Sky Survey. Follow-up observations with the University of Wyoming Infrared Observatory helped set the distance of the new cluster at about 9,000 light-years from Earth -- closer than most clusters -- and set the mass at the equivalent of 300,000 Suns. The cluster's apparent size, as viewed from Earth, is comparable to a grain of rice held at arm's length. It is located in the constellation Aquila. Astronomers believe that this cluster may be one of the last in our galaxy to be uncovered. The Two Micron All-Sky Survey false-color image was obtained using near-infrared wavelengths ranging from 1.3 to 2.2 microns. The Spitzer false-color image composite was taken on April 21, 2004, by its infrared array camera. It is composed of images obtained at four mid-infrared wavelengths: 3.6 microns (blue), 4.5 microns (green), 5.8 microns (orange) and 8 microns (red). The true-color image from the Digitized Sky Survey was acquired with red and blue filters.

Title Spitzer Digs Up Galactic Fossil
Description This false-color image taken by NASA's Spitzer Space Telescope shows a globular cluster previously hidden in the dusty plane of our Milky Way galaxy. Globular clusters are compact bundles of old stars that date back to the birth of our galaxy, 13 or so billion years ago. Astronomers use these galactic "fossils" as tools for studying the age and formation of the Milky Way. Most clusters orbit around the center of the galaxy well above its dust-enshrouded disc, or plane, while making brief, repeated passes through the plane that each last about a million years. Spitzer, with infrared eyes that can see into the dusty galactic plane, first spotted the newfound cluster during its current pass. A visible-light image (inset) shows only a dark patch of sky. The red streak behind the core of the cluster is a dust cloud, which may indicate the cluster's interaction with the Milky Way. Alternatively, this cloud may lie coincidentally along Spitzer's line of sight. Follow-up observations with the University of Wyoming Infrared Observatory helped set the distance of the new cluster at about 9,000 light-years from Earth -- closer than most clusters -- and set the mass at the equivalent of 300,000 Suns.

Title Smoke over Jackson Hole, Wyoming
Original Caption Released with Image These Multi-angle Imaging SpectroRadiometer (MISR) images acquired on July 27, 2001 (Terra orbit 8554) show the area around Jackson Hole, Wyoming, where the Green Knoll forest fire has raged for many days. Due to this year's low humidity, officials from the Grand Teton National Park and Bridger-Teton National Forest Interagency Fire Management Office announced a high risk for the area. The Green Knoll blaze is suspected to have been sparked by a campfire, and is located a few kilometers southwest of the town of Jackson. About 4600 acres have been scorched by the fire. Mandatory evacuations of some of the subdivisions near the town of Wilson were ordered, and on July 27 the fire had crept to within 300 meters of buildings. By July 29, the fire was reported to be 60-70% contained, thanks to the valiant efforts of over 1000 firefighters and the assistance of about one-fourth of the nation's air tankers. Improved weather conditions, including lighter winds, cooler temperatures and higher humidity, also helped matters. More information is available at the Grand Teton National Park and US Forest Service shared interagency website, http://www.tetonfires.com [ http://www.tetonfires.com ] At the left of this image set is a true-color view from MISR's 70-degree forward-viewing camera, covering an area of about 240 kilometers x 340 kilometers. The oblique angle of view accentuates the visibility of smoke, which can be seen as a thin bluish-white haze over the Jackson Hole valley. At top right is a cropped version of this picture, rotated counterclockwise to facilitate comparison with the stereo anaglyph beneath it. The anaglyph was created from MISR's 70-degree and 60-degree forward views, and requires a rotated orientation in order to produce a 3-D effect. Viewing the anaglyph in stereo helps to visualize the local topography and to differentiate the Green Knoll smoke plume from the higher nearby clouds. Stereoscopic viewing requires red/blue glasses with the red filter placed over your left eye. Information on ordering 3-D glasses is availablehere [ http://photojournal.jpl.nasa.gov/Help/VendorList.html#Glasses ]. Yellowstone Lake is visible at the center of the left-hand image, and is surrounded by Yellowstone National Park, the world's oldest national park. To the west of Jackson Hole is the Teton Range, with the peak of Grand Teton rising 4196 meters above sea level. At the lower right of the left-hand image is the Wind River Range, containing Gannett Peak, the highest point in Wyoming at 4207 meters. The Continental Divide runs through this range. MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology.
