| Title |
A Shocking Surprise in Stephan's Quintet |
| Description |
This false-color composite image of the Stephan's Quintet galaxy cluster clearly shows one of the largest shock waves ever seen (green arc), produced by one galaxy falling toward another at over a million miles per hour. It is made up of data from NASA's Spitzer Space Telescope and a ground-based telescope in Spain. Four of the five galaxies in this image are involved in a violent collision, which has already stripped most of the hydrogen gas from the interiors of the galaxies. The centers of the galaxies appear as bright yellow-pink knots inside a blue haze of stars, and the galaxy producing all the turmoil, NGC7318b, is the left of two small bright regions in the middle right of the image. One galaxy, the large spiral at the bottom left of the image, is a foreground object and is not associated with the cluster. The titanic shock wave, larger than our own Milky Way galaxy, was detected by the ground-based telescope using visible-light wavelengths. It consists of hot hydrogen gas. As NGC7318b collides with gas spread throughout the cluster, atoms of hydrogen are heated in the shock wave, producing the green glow. Spitzer pointed its infrared spectrograph at the peak of this shock wave (middle of green glow) to learn more about its inner workings. This instrument breaks light apart into its basic components. Data from the instrument are referred to as spectra and are displayed as curving lines that indicate the amount of light coming at each specific wavelength. The Spitzer spectrum showed a strong infrared signature for incredibly turbulent gas made up of hydrogen molecules. This gas is caused when atoms of hydrogen rapidly pair-up to form molecules in the wake of the shock wave. Molecular hydrogen, unlike atomic hydrogen, gives off most of its energy through vibrations that emit in the infrared. This highly disturbed gas is the most turbulent molecular hydrogen ever seen. Astronomers were surprised not only by the turbulence of the gas, but by the incredible strength of the emission. The reason the molecular hydrogen emission is so powerful is not yet completely understood. Stephan's Quintet is located 300 million light-years away in the Pegasus constellation. This image is composed of three data sets: near-infrared light (blue) and visible light called H-alpha (green) from the Calar Alto Observatory in Spain, operated by the Max Planck Institute in Germany, and 8-micron infrared light (red) from Spitzer's infrared array camera. |

TRMM Looks at the Rain Fueling Hurricane Ivan on September 15, 2004 |
| Abstract |
NASA's TRMM spacecraft is used by meteorologists to understand Hurricane Ivan. TRMM snapped this view of Hurricane Ivan on September 15, 2004 just before the storm strikes land. The cloud cover is taken by TRMM's Visible and Infrared Scanner (VIRS). The rain structure is taken by TRMM's Precipitation Radar (PR). It 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. High vertical bands on the outside of the storm indicated that Hurricane Ivan was very likely to spawn tornados in Florida and Georgia. |

Gulf Coast after Hurricane Ivan |
| Description |
Pensacola, Florida, was one of the cities hardest hit when Hurricane Ivan blasted ashore on September 16, 2004. Two days later, on September 18, the Ikonos satellite captured this view of the disaster. Piles of boats have been pushed against the shore in contrast to the neat lines parked along the harbor on January 4, 2003. The buildings around the harbor have also sustained damage. Sections of roof appear to be missing from the white building in the bottom right corner. The buildings in the upper right corner of the image also appear to be seriously damaged. What had been parking lots in January 2003 now appear to be covered in mud, possibly a result of flooding. Hurricane Ivan had winds of 130 miles per hour when it came ashore. The storm also brought coastal flooding, with a storm surge 10 to 15 feet above normal high-tide levels and heavy rain. The Associated Press reports that up to 52 people died in the United States as Ivan made its way up the East Coast from Alabama and Florida.

The parking lots that lined the beach in December 2001 have disappeared under a blanket of sand. The turquoise swimming pool and buildings along the lower right edge of the image are also gone, as are a number of structures a bit further inland. Not all of the changes are storm-related—a tall new building has been built on the beach near the image center. The building is casting a long shadow on the sand in the 2004 image.

*Gulf Coast after Hurricane Ivan* Hurricane Ivan slammed ashore on September 16, 2004, bringing devastation to the United States? Gulf Coast. Pensacola, in the western tip of the Florida panhandle, took the full brunt of the Category 3 storm as it pushed its way ashore. The storm?s 130 mile-per-hour winds, heavy rains, and 10 to 15 foot storm surge wreaked havoc on coastal communities such as Pensacola. This Ikonos image pair shows some of the damage around Bayou Chico in Pensacola. The large warehouse that is so prominently visible in the image acquired on January 4, 2003, appears to be a pile of rubble on September 18, 2004. Some of the boats docked along the shore appear to have drifted, and the land near the water?s edge looks dirty, as if recently covered by flood water. Hurricane Ivan had winds of 130 miles per hour when it came ashore. The storm also brought coastal flooding with a storm surge flooding of 10 to 15 feet above normal high tide levels and heavy rain.

Hurricane Frances
| Title |
Hurricane Frances |
| Description |
By the morning of September 4, 2004, Hurricane Frances had dropped in intensity from a maximum of category 4 (with 140 mph winds) to category 2 (105 mph winds). At the same time, the storm slowed to a standstill, delaying its arrival on the Florida coast and delivering sustained hurricane-force winds and heavy rainfall to the Bahamas. At 5:00 PM Eastern Daylight Time the National Weather service predicted the storm would intensify slightly and strike Florida in the early hours of the morning. Because of the slow speed of the storm, extremely high total rainfall amounts are possible. After crossing Florida, Frances will likely weaken to a tropical storm and move over Mississippi and Alabama on Monday. For hurricane updates, visit the National Hurricane Center. [ http://www.nhc.noaa.gov/ ] This image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA's Terra [ http://terra.nasa.gov/ ] satellite at 12:00 pm EDT September 4, 2004.

Hurricane Ivan |
| Description |
The Tropical Rainfall Measuring Mission [ http://trmm.gsfc.nasa.gov ] (TRMM) satellite looked into the heart of Hurricane Ivan at 05:09 UTC (1:09 AM EDT) on September 15, 2004. This satellite overflight happened approximately one day before Ivan made landfall in Alabama and before Ivan was within range of the National Weather Service?s weather radars. The TRMM Precipitation Radar captured this view of the heavy rain in the eyewall that surrounds the quiet eye of the storm. Unlike the eye, the eyewall is the portion of the hurricane with the most violent surface winds and with strong convective rainfall. Scientists believe that particularly tall regions of rain in the eyewall are associated with increases in the intensity of the surface winds?and wind intensity is particularly difficult to forecast. In the top view of the storm, there is a heavy arc of rain between the Points A and B. In the side view of the storm, it becomes clear that the tallest region of rainfall is near Point A. In both cases, the blue three dimensional volume contains all regions where there is light rainfall (at least 2 mm/h) as measured by the TRMM Precipitation Radar. The red volume contains all regions of heavy rainfall (at least 25 mm/h). In the side view, the rain region near Point A is approximately 12 km (7.5 miles) high. The vertical dimension has been stretched to make it easier to see the structure of the storm. The height of the cloud top is not necessarily the same as the height of the region of rain inside the clouds. In fact, the TRMM instruments show a dramatic difference between cloud height and rain height around the eye of Hurricane Ivan. While the TRMM Precipitation Radar saw the heaviest rain to the northeast of the central eye, TRMM infrared data show a pair of very tall cloud tops to the north and south of the eye. In the infrared image, dark gray indicates warm clouds that are therefore low and white and pink indicate cold clouds that are therefore higher up. The gray rectangle locates the position of the Precipitation Radar image shown above. While it was still a day before Hurricane Ivan?s eye reached Alabama, Ivan?s outer rain bands were already brushing past Florida. The large-scale rain features of Hurricane Ivan can be seen in this composite that uses data from the TRMM Microwave Imager (TMI). The gray rectangle indicates the position of the TRMM infrared image. TRMM is a joint mission between NASA and the Japanese Aerospace Exploration Agency (JAXA).

In the top view of the storm, there is a heavy arc of rain between the Points A and B. In the side view of the storm, it becomes clear that the tallest region of rainfall is near Point A. In both cases, the blue three dimensional volume contains all regions where there is light rainfall (at least 2 mm/h) as measured by the TRMM Precipitation Radar. The red volume contains all regions of heavy rainfall (at least 25 mm/h). In the side view, the rain region near Point A is approximately 12 km (7.5 miles) high. The vertical dimension has been stretched to make it easier to see the structure of the storm. The height of the cloud top is not necessarily the same as the height of the region of rain inside the clouds. In fact, the TRMM instruments show a dramatic difference between cloud height and rain height around the eye of Hurricane Ivan. While the TRMM Precipitation Radar saw the heaviest rain to the northeast of the central eye, TRMM infrared data show a pair of very tall cloud tops to the north and south of the eye. In the infrared image, dark gray indicates warm clouds that are therefore low and white and pink indicate cold clouds that are therefore higher up. The gray rectangle locates the position of the Precipitation Radar image shown above. While it was still a day before Hurricane Ivan?s eye reached Alabama, Ivan?s outer rain bands were already brushing past Florida. The large-scale rain features of Hurricane Ivan can be seen in this composite that uses data from the TRMM Microwave Imager (TMI).

Hurricane Katrina Erodes the U.S. Gulf Coast |
| Description |
The graceful curve of the Chandeleur Islands resembles a multi-boned spine connecting the Mississippi Gulf coast to the delta of the Mississippi River in Louisiana. Like all barrier islands, the Chandeleur Islands form a thin protective wall between the open sea and the mainland, in this case Louisiana's St. Bernard Parish. The islands absorb the strongest waves, sheltering the mainland during large storms. It is no surprise, then, that barrier islands along the U.S. Gulf Coast changed dramatically in the wake of Hurricane Katrina, and no change is as dramatic as that seen in the Chandeleur Islands. Hurricane Katrina's strong winds, storm surge, and battering waves scoured the islands, leaving them reduced or gone altogether. These images of the islands were taken by the Landsat 5 satellite. The top image, taken on September 16, 2005, shows the Mississippi and Alabama coast line, including the line of islands that bore the brunt of Katrina's fury. The lower images show the northern section of the Chandeleur Islands at full resolution. In the 11 months that passed between October 15, 2004, when the right image was taken, and September 16, 2005, when the left image was taken, the islands have wasted away. Barrier islands like the Chandeleur Islands are constantly building, eroding, and shifting under the normal actions of wind and waves. A powerful storm like Katrina can produce changes that otherwise may have taken many years, and most of the change seen here is probably a result of Katrina. Hurricane Dennis also gave the islands a glancing blow on July 10, 2005, and may be responsible for some of the change. The other barrier islands shown in the top image were also scoured by Katrina. The large images show that the Ship Islands [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13130 ] are now significantly smaller than they were in 2004, and Dauphin Island [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13132 ] has been cut in two. To read more about Katrina's impact on the Gulf Coast, please visit the United States Geological Survey's Hurricane Katrina Impact Studies [ http://coastal.er.usgs.gov/hurricanes/katrina/ ] page.

This image of fires in the southern United States was captured on March 10, 2004, by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite. Actively burning fires have been marked with red dots in Oklahoma (top left), Texas (bottom left), Arkansas (top center), Louisiana (bottom center), and (left to right across the rest of the image) Mississippi, Alabama, Florida, and Georgia. Most of us don?t think of late winter as fire season in the United States, but according to the Southern Coordination Center for the National Interagency Fire Center, just over 993,000 acres had been affected by fire in the Southern region as of March 23, 2004: 11,936 human-caused fires affected 130,385 acres, 18 lightning-caused fire affected 225 acres, and 1,084 prescribed fires (those set by land management agencies for natural resource management purposes) affected 862,772 acres.

Train of Hurricanes Floods Florida |
| Description |
*Train of Hurricanes Floods Florida* A rapid succession of four hurricanes over a period of six weeks has taken a toll on the river and lakes of Florida. This series of false-color images tracks the changes in Central Florida where Hurricanes Charley, Frances, and Jeanne came ashore. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA?s Terra [ http://terra.nasa.gov/ ] and Aqua [ http://aqua.nasa.gov/ ], satellites captured all of these images, in which water is black, vegetation is green, and clouds are light blue. The first image was acquired on July 22, 2004, before any of the storms affected the region. Lake Okeechobee is the large body of water in the lower right corner of the image, and Charlotte Harbor is the southernmost body of water on the western shore. On August 13, Hurricane Charley made a surprise landfall over Punta Gorda, Florida, as a Category 4 Hurricane on the Saffir-Simpson Hurricane Scale. From Punta Gorda, which is on the northeast side of Charlotte Harbor, Charley moved northeast across Florida into the Atlantic Ocean. The changes between July 22 and August 17 are subtle. The mouth of the Peace River on the northeast corner of Charlotte Harbor looks a little larger, and the Manatee River just below Tampa Bay, left center, also looks swollen. A few of the lakes in the center of Florida also look larger than they did previously. On September 5, Florida?s second major hurricane slammed ashore near Stuart, on the eastern shore of Florida, almost directly opposite Charley?s landfall. Throughout the day on September 5, Frances moved slowly northwest across Florida, crossing the same regions Charley had just three weeks before. In the time between Frances and Florida?s next storm, Hurricane Ivan, MODIS captured no cloud-free images. However, the view after Ivan?s landfall shows marked changes in the region. Hurricane Ivan pummeled northwest Florida and Alabama on September 16, before moving north across Alabama and Georgia. Though the storm did not directly affect the region shown in these images, flooding is clearly evident in the post-storm image acquired on September 18. It is likely that much of this flooding was induced by Hurricane Frances, but it is also possible that some the flooding is being caused by runoff from Ivan-related rainfall in the north. The most obvious change is in Lake Harney, west of the ?v?-shaped Cape Canaveral on Florida?s east coast. The lake and the river running from it, St Johns River, are not clearly visible on July 22. By September 18, a black smudge over the area reveals an excess of water. The Kissimmee River running from Lake Kissimmee to Lake Okeechobee also looks flooded, as does the Peace River northeast of Charlotte Harbor. The final hurricane to ravage Florida in September and August was Hurricane Jeanne, which came ashore on September 26 over Fort Pierce, just a few miles north of the point where Frances made landfall. Like Frances, Jeanne moved northwest across Florida, dumping heavy rain on regions already soaked by previous storms. The cumulative effect of four hurricanes is seen in the final image, acquired on September 28, 2004. Most notably, St. Johns River west of Cape Canaveral is greatly swollen.

A few of the lakes in the center of Florida also look larger than they did previously. On September 5, Florida?s second major hurricane slammed ashore near Stuart, on the eastern shore of Florida, almost directly opposite Charley?s landfall. Throughout the day on September 5, Frances moved slowly northwest across Florida, crossing the same regions Charley had just three weeks before. In the time between Frances and Florida?s next storm, Hurricane Ivan, MODIS captured no cloud-free images. However, the view after Ivan?s landfall shows marked changes in the region. Hurricane Ivan pummeled northwest Florida and Alabama on September 16, before moving north across Alabama and Georgia. Though the storm did not directly affect the region shown in these images, flooding is clearly evident in the post-storm image acquired on September 18. It is likely that much of this flooding was induced by Hurricane Frances, but it is also possible that some the flooding is being caused by runoff from Ivan-related rainfall in the north. The most obvious change is in Lake Harney, west of the ?v?-shaped Cape Canaveral on Florida?s east coast. The lake and the river running from it, St Johns River, are not clearly visible on July 22. By September 18, a black smudge over the area reveals an excess of water. The Kissimmee River running from Lake Kissimmee to Lake Okeechobee also looks flooded, as does the Peace River northeast of Charlotte Harbor. The final hurricane to ravage Florida in September and August was Hurricane Jeanne, which came ashore on September 26 over Fort Pierce, just a few miles north of the point where Frances made landfall. Like Frances, Jeanne moved northwest across Florida, dumping heavy rain on regions already soaked by previous storms. The cumulative effect of four hurricanes is seen in the final image, acquired on September 28, 2004. Most notably, St. Johns River west of Cape Canaveral is greatly swollen.
