| Full Description |
This close-up view shows an inner region of Saturn's C ring. It covers a radial location on the rings located approximately 78,000 to 80,500 kilometers (48,500 to 50,000 miles) from the center of the planet. Saturn itself has a radius of 60,330 kilometers (34,490 miles). A bright feature, informally referred to as a "plateau," arcs across the image center. The plateau is not high in terms of elevation, but rather in terms of particle density (seen here as brightness). The density is fairly uniform within the bright band, and some five times higher than in the surrounding ring structure. Although the many plateaus in Saturn's rings appear unchanged over 25 years of observations, scientists do not know what determines their locations or maintains their sharp boundaries. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Sept. 5, 2005, at a distance of approximately 418,000 kilometers (260,000 miles) from Saturn. The image scale is 2 kilometers (1 mile) per pixel. The Cassini-Huygens mission is a cooperative project of NASA, the 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 operations center is based at the Space Science Institute in Boulder, Colo.

TRMM Observes Hurricane Wilma on October 19, 2005 |
| Abstract |
NASA's TRMM spacecraft observed this view of Hurricane Wilma on October 19, 2005 at 1740Z. At this time the storm was classified as the most dangerous category five. Wilma had record low minimum pressure readings of 893 mb and sustained winds of 140 knots (161 mph). The cloud cover is taken by TRMM's Visible and Infrared Scanner(VIRS) and the GOES spacecraft. The rain structure is taken by TRMM's Tropical Microwave Imager (TMI) and TRMM's Precitation Radar(PR) instruments. TRMM looks underneath of the storm's clouds to reveal the underlying rain structure. Blue represents areas with at least 0.25 inches of rain per hour. Green shows at least 0.5 inches of rain per hour. Yellow is at least 1.0 inches of rain and red is at least 2.0 inches of rain per hour. |

| Title |
Hurricane Wilma |
| Description |
Hurricane Wilma was a powerful Category 5 storm when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite took this image at 12:40 p.m. Eastern Daylight Time, on October 19, 2005. Less than 24 hours before this image was taken, Wilma had rapidly grown into a record-breaking, powerful storm. Winds around the eyewall of the storm were raging at 280 kilometers per hour (175 miles per hour). Just hours before, National Oceanographic and Atmospheric Administration (NOAA) aircraft measured a record-low air pressure of 882 millibars in the center of Hurricane Wilma, making it the most intense hurricane ever observed in the Atlantic basin. Wilma also broke records for the fastest development of a storm, going from tropical storm status to Category 5 hurricane in less than 24 hours. The high-resolution image provided above has a spatial resolution of 250 meters per pixel. The MODIS Rapid Response Team provides this image at additional resolutions.

Hurricane Wilma
| Title |
Hurricane Wilma |
| Description |
On the morning of October 19, 2005, National Oceanographic and Atmospheric Administration (NOAA) aircraft measured a pressure of 882 millibars in the center of Hurricane Wilmathe lowest pressure ever measured in an Atlantic hurricane. This low pressure earned Wilma the status of the strongest hurricane ever recorded in the Atlantic. As of October 20, the storm was moving northward through the western Caribbean Sea and toward the Yucatan Channel, which separates Mexico from Cuba. Predictions at that time were that once Wilma moved into the Gulf of Mexico, westerly winds would begin steering the storm toward Florida. In this image, Wilma is sprawled across the entire western Caribbean Sea, with bands of clouds reaching from the Yucatan Peninsula and Honduras (left and lower left, respectively) all the way to Cuba and Jamaica (upper right and center right edge). The image is one frame of an animation that shows the development of the storm between 8:15 p.m. (Eastern Daylight Time) on October 18 and 4:45 p.m. on October 19 (00:15 to 20:45 UTC on October 19). At the beginning of the animation, the core of the storm is a smaller, bright disk of clouds off the coast of Honduras. Over the course of the animation, Wilma grows larger and spins and wobbles its way west-northwest. Thunderstorms embedded in the hurricane's spiraling cloud bands explode and then subside over the course of the animation. This image shows visible data collected by NOAA's Geostationary Operational Environmental Satellite (GOES), combined with land surface data collected by NASA's Moderate Resolution Imaging Spectroradiometer instrument. The animation uses GOES infrared data during the nighttime part of the animation (up until about 8:45 a.m on October 19) and visible data in the daytime portion.

Hurricane Wilma Colors the C
| Title |
Hurricane Wilma Colors the Caribbean |
| Description |
The Caribbean Sea glowed a brilliant blue on October 23, 2005, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured this image. The cloud of blue is a sign of Hurricane Wilma's recent passage, it was over these waters that Wilma exploded from a weak Category 1 hurricane with sustained winds of 130 kilometers per hour (80 miles per hour) to the most powerful hurricane ever observed. This record-breaking intensification took place in the scant space of 12 hours between October 18 and October 19, 2005. With winds of 280 km/hr (175 mph), the storm moved slowly northwest toward the Yucatan Peninsula, churning the warm ocean waters and bringing sediment from the ocean floor to the surface. It is the sediment that scatters light, giving the water its brilliant color. The ocean is shallow in this area, and a series of banks and coral reefs [ http://oceancolor.gsfc.nasa.gov/cgi/reefs.pl?I1SW.x=196&I1SW.y=40 ] can be seen under the surface when waters are clear. The blue cloud traces out the outline of the bank where waters were shallow enough to stir up bottom sediment. The deeper water around the bank remains dark blue. Along the shore, flood-laden rivers pour mud into the ocean. The dirt fans out in tan, and then green plumes. The extra nutrients the run-off and bottom sediment bring to the surface may be feeding surface-dwelling ocean plants, which can also color ocean waters turquoise. To read more about how hurricanes stir up ocean sediments, see "State of (Re)Suspense" [ http://daac.gsfc.nasa.gov/oceancolor/scifocus/oceanColor/resuspension.shtml ], a NASA Science Focus! article.

Fires in Northwestern India |
| Description |
In northwestern India on October 19, 2005, smoke from scores of agricultural fires created a thick haze across the plains at the base of the Himalaya Mountains (upper right). This image of the region was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua [ http://aqua.nasa.gov ] satellite. The air quality in the region is often influenced by fires, dust storms, and urban pollution. The high-resolution image provided above has a spatial resolution of 250 meters per pixel. The MODIS Rapid Response Team provides this image at additional resolutions.

Fires in Russia's Far East |
| Description |
In Russia's Far East, numerous fires were billowing thick smoke on October 19, 2005, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua [ http://aqua.nasa.gov ] satellite captured this image of the region. Active fires are marked in red. Many of the fires are burning in the Amur River valley, the low-lying area to the west of the forest-covered coastal mountains. Smoke spreads eastward over the Sea of Okhotsk (image right). NASA image created by Jesse Allen, Earth Observatory, using data provided courtesy of the MODIS Rapid Response team. |
