Julia is waning in the eastern Atlantic Ocean because of outflow from massive Hurricane Igor, despite his distance far to the west. Satellite imagery from NASA's Aqua satellite showed that Julia's eye was no longer visible, a sign that she's weakening. As NASA's Aqua satellite flew over Hurricane Julia from space on Sept. 16 at 1:35 p.m. EDT, the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument captured a visible image of the storm. In the MODIS image, Julia's eye was no...

Hurricane Julia intensified rapidly overnight and is now a Category 4 hurricane on the Saffir-Simpson Scale and NASA's Aqua, Terra and TRMM satellites captured clues as they passed over her from space. The Tropical Rainfall Measuring Mission (TRMM) satellite passed over intensifying hurricane Julia during the afternoon of Sept. 14 and captured very heavy rain falling at 1807 UTC (2:07 p.m. EDT). That heavy rainfall was a clue that she would intensify overnight, and today, Sept. 15, she has...

Hurricane Igor is a monster hurricane in terms of strength and size. To get a perspective on its size, it is the same distance from one end of the storm to the other as it is from Boston, Mass. to Richmond, Va., some 550 miles. That's a 10-hour drive from one end to the other, and NASA satellites captured that entire distance in one image. Because Hurricane Igor is a large storm and even if Igor doesn't make a direct landfall in Bermuda, the extent of the winds (the wind field) is so large...

In the midst of a difficult fire season in many parts of the world, the United Nations' (UN) Food and Agriculture Organization has launched a new online fire detection system that will help firefighters and natural hazards managers improve response time and resource management. The Global Fire Information Management System (GFIMS) delivers fire data from an imaging sensor aboard NASA's Terra and Aqua satellites to generate daily fire maps and images through a freely accessible Web interface....

NASA's Terra satellite captured the changing Tropical Storm Kompasu over Korea and China very early today, as it makes its way east to northern Japan. It is becoming extratropical. The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard NASA's Terra satellite captured a visible image of Tropical Storm Kompasu at 02:15 UTC on Sept. 2 (10:15 p.m. EDT Sept. 1) as it was moving over Korea and China. The storm appeared disorganized as there was no visible center of circulation....

NASA satellites working in high gear NASA's Aqua, Terra and TRMM satellites are providing data on Hurricane Danielle daily, and forecasters are using that data to help determine Danielle's behavior and movement. At 5 p.m. EDT yesterday, August 23, when Danielle became a hurricane, these NASA satellites fed forecasters data on cloud extent and formation, cloud top temperatures, pressure, sea surface temperatures, rainfall rates within the storm and more factors. By 5 a.m. EDT today, August 24,...

One of the most destructive storms in years struck Washington, D.C. and the surrounding area on July 25, 2010. Strong winds downed trees and power lines, leaving hundreds of thousands of residents without power, stopping elevators, and darkening malls and movie theaters. Falling trees killed at least two people. The following morning, crews were working furiously to restore power to homes, traffic lights, and even a water treatment plant. The Geostationary Operational Environmental Satellite...

WASHINGTON, July 20 /PRNewswire-USNewswire/ -- Scientists have produced a first-of-its kind map of the height of the world's forests by combining data from three NASA satellites. The map will help scientists build an inventory of how much carbon the world's forests store and how fast that carbon cycles through ecosystems and back into the atmosphere.

The Earth floats delicately in space, sunlight illuminating the fluid mottling of white clouds suspended over its surface. The scene, the leading sequence in a recent NASA video about ship pollution and clouds, shows our planet from a perspective only a satellite or spacecraft could provide. However, no camera captured that image of the Earth. The reason? It's not one image. Instead, the single cloud-scattered globe is a mosaic of 298 smaller images of close-up areas of our planet...

NASA's Aqua satellite flew over the Gulf of Mexico on Thursday, June 10 at 19:05 UTC (3:05 p.m. EDT) and the satellite's Moderate Resolution Imaging Spectroradiometer (MODIS) instrument captured an image of the thickest part of the oil slick. In the image, the oil slick in the Gulf of Mexico is positioned in sunglint. In the sunglint region"”where the mirror-like reflection of the Sun gets blurred into a wide, bright silvery-gray strip"”differences in the texture of the water...
