Haze over Europe
This true-color Sea-viewing Wide Field-of-view Sensor (SeaWiFS) image of central Europe showsan atmospheric low-pressure system centered just south of the Baltic Sea. There is widespread aerosol pollution (gray pixels) over the region that appears to be converging on the low-pressure…
Significant Event Report for Week Ending 3/28/2003
Cassini Significant Event Report For Week Ending 03/28/03 The most recent spacecraft telemetry was acquired from the Canberra tracking station on Wednesday, March 26. The Cassini spacecraft is in an excellent state of health and is operating normally. Information on…
Measuring Ozone from Space Shuttle Columbia
New remote-sensing technology called limb viewing allows observation of the atmosphere from the side rather than straight down. From that side view the layers of the atmosphere appear like layers in a cake, allowing instruments to see the lower layers…
Windswept Shores of the Aral Sea
browse image of orbit 15741 As recently as the 1960’s the Aral Sea of Kazakhstan and Uzbekistan wasthe fourth-largest inland sea in the world. Since then, its water volumehas dropped by about 80% due to extensive irrigation systems developedduring the…
Dust and Smoke over Iraq and the Middle East
The Sea-viewing Wide Field-of-view Sensor (SeaWiFS) viewed dust in the skies over the northern Persian Gulf again today, Thursday, March 27, 2003. Also visible (in the full-resolution image) are a few plumes of dark smoke over the Fertile Crescent to…
Hubble Watches Light from Mysterious Erupting Star Reverberate Through Space
In January 2002, a dull star in an obscure constellation suddenly became 600,000 times more luminous than our Sun, temporarily making it the brightest star in our Milky Way galaxy. The mysterious star has long since faded back to obscurity,…
How On Earth Was This Image Made?
This image presents a remarkable view of the North Atlantic Ocean, stretching from the equator and western Africa northward to Iceland and Greenland, with sunset occurring over (north to south) Scandinavia, France, Spain, Algeria, Mali, and the Ivory Coast. How…
Dust and Smoke over Iraq and the Middle East
This true-color SeaWiFS image shows the counterclockwise swirl of a low-pressure system over the Middle East on the morning of March 26, 2003. The system appears to be scooping up dust (light brown pixels) from the deserts beneath it and…
How on Earth was this Image Made?
Remotely sensed Earth observations can include everything from sonar measurements used to map the topography of the ocean floor to satellite-based observations of city lights. Combining observations collected by a variety of instruments at different times and places allow scientists…
Mapping North America’s Wintry Weather
high resolution versionsFebruary 26 – March 5, 2002 (668 KBJPEG)February 26 – March 5, 2003 (688 KBJPEG) In California’s Sierra Nevada Mountains and North Carolina’s Outer Banks, Old Man Winter left a heavier-than-usual footprint this year. And yet his passing…
Haze over Eastern Europe
Eastern Europe is largely cloud free in today’s Sea-viewing Wide Field-of-view Sensor (SeaWiFS) image of the area, but a band of hazy air (gray pixels) appears to be moving over the northwestern portion of the Black Sea. This true-color scene…
Dust and Smoke over Iraq and the Middle East
On Tuesday, March 25, the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) captured this true-color scene of a very large dust storm blowing eastward over the Middle East region. The line of dust (tan pixels) can be seen in this image extending…
Lake Eyre, South Australia
Lake Eyre in South Australia is the terminal point for drainage in the Lake Eyre Basin, one of theworld’s largest internally draining systems. It sits 15 meters below sea level and is the largestsalt pan in the world. Spanning 9,300…
Page, Arizona
This isolated community near the northern Arizona border is of special interest because of its origin and location. Unlike other towns in the area, Page was created in 1957 to house workers and their families during the construction of nearby…
Pioneer 10 Sends Last Signal
After more than 30 years, it appears the venerable Pioneer 10 spacecraft has sent its last signal to Earth. Pioneer’s last, very weak signal was received on 23 January 2003.
Dust, Fires, and Smoke in Southern Iraq
These images of Iraq, Kuwait, and parts of Saudi Arabia and Iran were acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua and Terra satellites on March 20 and 21, 2003. The images show dust over the Middle…
Blizzard Hits Colorado
Parts of Colorado and Wyoming were engulfed in a record-setting blizzard between March 18 and 19, 2003. The Rocky Mountains were hammered with as much as 87 inches (7.25 feet) of snow in places, and Denver received about 30 inches,…
