Solar Storm Heads for Earth
Above the visible surface of the Sun is a blanket of plasma, gas that is so hot that some atoms have become “unglued,” creating a free-flowing mixture of positively charged atomic nuclei and negatively charged electrons. Invisible to the naked…

Phytoplankton Bloom off Patagonia
On December 5, 2006, a phytoplankton bloom sent colorful swirls through the southern Atlantic Ocean off the coast of Patagonia, Argentina. The Moderate Resolution Imaging Spectroradiometer (MODIS) flying onboard NASA’s Terra satellite captured this image the same day. In this…
Mudslides in the Philippines
Mayon Volcano, steep-sided and symmetric, rises 2,462 meters above the Albay Gulf and the city of Legazpi, the regional capital, with a population of more than 150,000. The most active volcano in the Philippines, Mayon turned deadly on November 30,…
Urban Heat Island: Atlanta, Georgia
Urbanization does more than just transform ecosystems, it also changes fundamental variables that influence weather and climate, such as land surface temperature, surface roughness, and evaporation. For many years scientists have documented the changes in land surface temperature that result…
Heavyweight Stars Light Up Nebula NGC 6357
The small open star cluster Pismis 24 lies in the core of the large emission nebula NGC 6357 in Scorpius, about 8,000 light-years away from Earth. Some of the stars in this cluster are extremely massive and emit intense ultraviolet…
Bernese Alps, Switzerland
The formidable mountain system of the Alps stretches across much of central Europe, with seven countries claiming portions of the mountains within their borders: Germany, France, Switzerland, Italy, Liechtenstein, Austria, and Slovenia. The glacial landscape of the Bernese Alps, located…

Irrigation and Land Surface Temperature in Oregon
he difference between poplar plantations and native vegetation is illustrated in this pair of satellite images, collected by the Advanced Spaceborne Thermal Emission and Reflection Radiometer ( ASTER ) on NASA’s Terra satellite on August 27, 2006.
Another Kelvin Wave Strenghtens El Nino
In the Pacific Ocean around the equator, persistent easterly winds, the trade winds, blow across the ocean. The strong, steady winds push surface waters westward, and in fact, the sea surface height in the western Pacific near Indonesia is about…
Urban Rain
Most city dwellers worry about what the weather will do to their city, but for meteorologist Marshall Shepherd, the real question is what are cities doing to the weather.
Eruption of Mount Nyamulagira (Nyamuragira)
Around 10:00 p.m. local time on November 27, 2006, Mount Nyamulagira erupted. Situated near the city of Goma in the eastern Democratic Republic of Congo (DRC), the volcano posed a danger to nearby wildlife as the animals could fall ill…
