2/6/09
Description A crippling heat wave and strong winds in southeastern Australia contributed to an outbreak of forest and grassland fires in Victoria in late January 2009. By January 30, about 5,500 hectares had burned and at least 10 homes had been destroyed, reported the Australian Broadcasting Corporation (ABC). The homes were located in a small community near the town of Boolara. Nearly surrounded by wildfire, the town had also run out of water and lost power, said ABC News. This image from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite was captured on January 30. A large plume of smoke spreads southward from a fire (outlined in red) that appears to be burning in a small area of forest west of Churchill (a larger town near Boolara) in Victoria's Gippsland region. The forest is dark green in contrast to the surrounding grass or cropland. The fire, says ABC News, started as two blazes in plantation forests in the Strzelecki Ranges. The large version of the scene shows a wider area that includes several other fires.

Description Bushfires in southeastern Australia turned deadly over the first weekend of February 2009. Out-of-control fires raced into small communities and towns in Victoria, and more than 100 people had died as of February 9, according to news reports. The Australian Broadcasting Corporation (ABC News) reported that many of those who died had remained to protect their homes. Among the most devastated communities were those in the Kinglake area and Marysville. As of February 9, firefighters were expressing concern about the increased activity of the fire around the town of Dederang, southwest of Lake Hume. This image shows the Barry Mountains of central Victoria on February 9, 2009. The image, captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite,is shown in false color, using visible, near-infrared and shortwave infrared light. Places where the sensor detected active fire are outlined in red. Burned areas are brick red, and places of intense heat -- often a sign of open flame in this kind of image -- are glowing pink. Smoke turns a transparent blue, which makes it easier to see the ground. Fire is a regular occurrence in the forests and grasslands of southeastern Australia, even in the absence of people. In the hot, dry summer months, vegetation dries out, lightning triggers many natural wildfires. However, in the past decade, the area has experienced several severe droughts, and in late January and early February, parts of South Australia, Victoria, and New South Wales were also paralyzed by an exceptional heatwave. Conditions were primed for devastating fires, some of which appear to have been started by lighting and others, according to news reports, by arson. The event was the worst fire disaster in Australia's history. > Labeled image > Photo-like image Image credit: NASA's Goddard Space Flight Center, MODIS Rapid Response Team Text credit: Rebecca Lindsey, NASA's Earth Observatory

Description Fires burned along the northeastern coast of Australia in early October 2009. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite captured this true-color image on October 6, 2009. Fires burn north, south, and inland from the coastal city of Cairns. Smoke from the fires consistently blows inland, toward the east or east-southeast. Red outlines indicate hotspots associated with high surface temperatures. On October 7, 2009, an article in The Courier-Mail warned of significant fire dangers for the coming summer. Rains the previous spring had boosted vegetation growth, but hot temperatures and dry conditions had left that vegetation prone to burning. In addition, the monsoon and cyclone season was expected to arrive a month late. A total of 1,700 fires had been contained in just the previous two weeks.

Amazing Andromeda Galaxy
Title Amazing Andromeda Galaxy
Description The many "personalities" of our great galactic neighbor, the Andromeda galaxy, are exposed in this new composite image from NASA's Galaxy Evolution Explorer and the Spitzer Space Telescope. The wide, ultraviolet eyes of Galaxy Evolution Explorer reveal Andromeda's "fiery" nature -- hotter regions brimming with young and old stars. In contrast, Spitzer's super-sensitive infrared eyes show Andromeda's relatively "cool" side, which includes embryonic stars hidden in their dusty cocoons. Galaxy Evolution Explorer detected young, hot, high-mass stars, which are represented in blue, while populations of relatively older stars are shown as green dots. The bright yellow spot at the galaxy's center depicts a particularly dense population of old stars. Swaths of red in the galaxy's disk indicate areas where Spitzer found cool, dusty regions where stars are forming. These stars are still shrouded by the cosmic clouds of dust and gas that collapsed to form them. Together, Galaxy Evolution Explorer and Spitzer complete the picture of Andromeda's swirling spiral arms. Hints of pinkish purple depict regions where the galaxy's populations of hot, high-mass stars and cooler, dust-enshrouded stars co-exist. Located 2.5 million light-years away, the Andromeda is our largest nearby galactic neighbor. The galaxy's entire disk spans about 260,000 light-years, which means that a light beam would take 260,000 years to travel from one end of the galaxy to the other. By comparison, our Milky Way galaxy's disk is about 100,000 light-years across. This image is a false color composite comprised of data from Galaxy Evolution Explorer's far-ultraviolet detector (blue), near-ultraviolet detector (green), and Spitzer's multiband imaging photometer at 24 microns (red).

Title MODIS Land Cover of Australia
Abstract New NASA satellite-generated land cover maps are providing scientists with a detailed picture of the distribution of Earth's ecosystems and land use Scientists can better determine how vegetation is distributed and land is being used around the world with new NASA satellite-generated land-cover maps. These new maps, based on a global digital database of land cover types Earth images that is updated every 16 days, will help scientists better understand the Earth's climate and carbon budget and climate, through closer monitoring of water and land resources, including forested and agricultural areas. These land-coverland cover maps were developed at Boston University in Boston, MA, using data from the Moderate-resolution Imaging-Spectroradiometer (MODIS) instrument aboard NASA's Terra satellite. The prototype MODIS maps were created with data acquired between July and December 2000, but future maps will utilize one year of data. Advances in remote sensing technology allow MODIS to collect higher-quality data than previous sensors, yielding the most detailed land cover classification maps to date. The new maps are better because the quality of MODIS data is much higher than AVHRR data. They are also more current because the information content of MODIS data allowed scientists to exploit more efficient automated methods for categorizing land cover than was were previously possible, reducing the time to generate maps from months or years to about one week. Each MODIS land-coverland cover map contains 17 different land cover types, differentiating among eleven natural vegetation types such as deciduous and evergreen forests, savannas, grasslands, permanent wetlands and shrublands. Agricultural land use , as well as, several categories of land surfaces with little or no plant cover -- such as bare ground, urban areas and permanent snow and ice -- are also depicted in the maps.

Title Chlorophyll Concentration Shows Oceanographic Patterns in Great Barrier Reef
Abstract Coral bleaching may be one of the greatest threats to the Great Barrier Reef. Coral bleaching is a stress response that often occurs when the surrounding waters become too warm for the corals. In the stressful situation, the corals expel their brownish zooxanthellae and lose their color. Zooxanthellae are unicellular yellow-brown algae that make it possible for the corals to grow and reproduce quickly enough to create reefs. Without the zooxanthellae, the coral cannot obtain sufficient nourishment. If conditions remain difficult, the corals may die. Major coral bleaching incidents on the Great Barrier Reef in 1998 and 2002 led to widespread death of corals in some areas. Researchers in the Barrier reef of Australia are using NASA's resources to help identify troubled coral.

Title Global Rotation of SeaWiFS Biosphere Decadal Average without Land
Abstract The SeaWiFS instrument aboard the Seastar satellite has been collecting ocean data since 1997. By monitoring the color of reflected light via satellite, scientists can determine how successfully plant life is photosynthesizing. A measurement of photosynthesis is essentially a measurement of successful growth, and growth means successful use of ambient carbon. This animation shows an average of 10 years worth of SeaWiFS data. Dark blue represents warmer areas where there tends to be a lack of nutrients, and greens and reds represent cooler nutrient-rich areas which support life. The nutrient-rich areas include coastal regions where cold water rises from the sea floor bringing nutrients along and areas at the mouths of rivers where the rivers have brought nutrients into the ocean from the land.

Title Earth at Night 2001
Abstract This is what the Earth looks like at night. Can you find your favorite country or city? Surprisingly, city lights make this task quite possible. Human-made lights highlight particularly developed or populated areas of the Earth's surface, including the seaboards of Europe, the eastern United States, and Japan. Many large cities are located near rivers or oceans so that they can exchange goods cheaply by boat. Particularly dark areas include the central parts of South America, Africa, Asia, and Australia. The above image is actually a composite of hundreds of pictures made by the Defense Meteorological Satellite Program (DMSP) currently operates four satellites carrying the Operational Linescan System (OLS) in low-altitude polar orbits. Three of these satellites record nighttime data. The DMSP-OLS has a unique capability to detect low levels of visible-near infrared (VNIR) radiance at night. With the OLS 'VIS' band data it is possible to detect clouds illuminated by moonlight, plus lights from cities, towns, industrial sites, gas flares, and ephemeral events such as fires and lightning-illuminated clouds. The Nighttime Lights of the World data set is compiled from the October 1994 - March 1995 DMSP nighttime data collected when moonlight was low. Using the OLS thermal infrared band, areas containing clouds were removed and the remaining area used in the time series. This animation is derived from an image created by Craig Mayhew and Robert Simmon from data provided by Christopher Elvidge of the NOAA National Geophysical Data Center.

Title Galileo Earth Views (WMS)
Abstract The Galileo spacecraft was launched from the Space Shuttle Atlantis on October 18, 1989 on a six-year trip to Jupiter. On the way, the trajectory of the spacecraft took it past Venus once and Earth twice. Galileo took the Earth images in this animation just after the first flyby of the Earth, on December 11 and 12, 1990. This six-hour sequence of images taken two minutes apart clearly shows how the Earth looks from space and how fast (or slow) the cloud features change when looked at from a distance. The path of the sun can be seen crossing Australia by its reflection in the nearby ocean, and the terminator region between night and day can be seen moving across the Indian Ocean. In the original images, the Earth's rotation is so dominant that cloud movement is hard to see, but these images have been mapped to the Earth is such a way that a viewer can watch just the clouds move in the ocean around Antarctica or across the Austrailian land mass. In this animation, New Zealand can ony be seen as a stationary disturbance under a moving cloud bank. The black area with the sharp boundary to the north and east of Australia is the side of the Earth that could not be seen from Galileo's position.

Abstract Coral bleaching may be one of the greatest threats to the Great Barrier Reef. Coral bleaching is a stress response that often occurs when the surrounding waters become too warm for the corals. In the stressful situation, the corals expel their brownish zooxanthellae and lose their color. Zooxanthellae are unicellular yellow-brown algae that make it possible for the corals to grow and reproduce quickly enough to create reefs. Without the zooxanthellae, the coral cannot obtain sufficient nourishment. If conditions remain difficult, the corals may die. Major coral bleaching incidents on the Great Barrier Reef in 1998 and 2002 led to widespread death of corals in some areas.

Abstract Coral bleaching may be one of the greatest threats to the Great Barrier Reef. Coral bleaching is a stress response that often occurs when the surrounding waters become too warm for the corals. In the stressful situation, the corals expel their brownish zooxanthellae and lose their color. Zooxanthellae are unicellular yellow-brown algae that make it possible for the corals to grow and reproduce quickly enough to create reefs. Without the zooxanthellae, the coral cannot obtain sufficient nourishment. If conditions remain difficult, the corals may die. Major coral bleaching incidents on the Great Barrier Reef in 1998 and 2002 led to widespread death of corals in some areas. Researchers in the Barrier reef of Australia are using NASA's resources to help identify troubled coral. Currently, the most severe coral bleaching occurs over inshore reefs where the Sea Surface Temperatures are showing increased temperatures.

Earth At Night (WMS)
Title Earth At Night (WMS)
Abstract This image of Earth's city lights was created with data from the Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS). Originally designed to view clouds by moonlight, the OLS is also used to map the locations of permanent lights on the Earth's surface. The brightest areas of the Earth are the most urbanized, but not necessarily the most populated. (Compare western Europe with China and India.) Cities tend to grow along coastlines and transportation networks. Even without the underlying map, the outlines of many continents would still be visible. The United States interstate highway system appears as a lattice connecting the brighter dots of city centers. In Russia, the Trans-Siberian railroad is a thin line stretching from Moscow through the center of Asia to Vladivostok. The Nile River, from the Aswan Dam to the Mediterranean Sea, is another bright thread through an otherwise dark region. Even more than 100 years after the invention of the electric light, some regions remain thinly populated and unlit. Antarctica is entirely dark. The interior jungles of Africa and South America are mostly dark, but lights are beginning to appear there. Deserts in Africa, Arabia, Australia, Mongolia, and the United States are poorly lit as well (except along the coast), along with the boreal forests of Canada and Russia, and the great mountains of the Himalaya.
