The European Alps stretch 1,200 kilometers (750 miles) across eight countries, and it's the longest mountain chain situated entirely within Europe. The Alps include more than 100 peaks higher than 4,000 meters (13,000 feet), and this image from NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) on its Terra satellite beautifully captures a recent snowfall across the region.
A new study by NASA and several partners found that in California's Sierra Nevada, atmospheric river storms are two-and-a-half times more likely than other types of winter storms to result in destructive rain-on-snow events, where rain falls on existing snowpack, causing it to melt.
The Group on Earth Observations (GEO) introduced the Early Warning Crop Monitor (EWCM), a new tool that provides consensus reports on crop conditions in countries at risk of food insecurity in Central and South America, Africa, the Middle East, and Central and East Asia.
Students participating in NASA's EarthKAM program can request photographs of specific Earth features, such as this image of South Africa, which are taken by a special camera mounted on the International Space Station when it passes over those features.
Carbon tetrachloride (CCl4), once commonly used as a cleaning agent, is a known air toxin that eats away at the ozone layer. Its production has been banned for many years, but a new CIRES and NOAA study reports those rates are still 30-100 times higher than amounts reported to emission inventories.
Using data from the NASA/USGS Landsat 8 satellite, researchers have detected sediment plumes extending as far as four kilometers downstream from shallow shipwreck sites, demonstrating how satellites may be used to locate the watery graves of coastal shipwrecks.
On March 9, 2016, and approximately 1 million miles from Earth, NASA's Deep Space Climate Observatory (DSCOVR) captured the shadow of the Moon moving across Earth's sunlit face.
A new NASA study used remote-sensing and tree-ring data to conclude that the recent drought that began in 1998 in the eastern Mediterranean Levant region (Cyprus, Israel, Jordan, Lebanon, Palestine, Syria and Turkey) is likely the worst drought of the last nine centuries.
Two weeks after its successful launch on Feb. 16, 2016, the Copernicus Sentinel-3A satellite captured its first image, the transition from day to night over Svalbard, Norway.
After more than 100 years of dormancy, Nicaragua's Momotombo volcano has erupted more than 80 times in the last three months. Momotombo rises from a chain of 19 active volcanos that run northwest to southeast in western Nicaragua, one of the most volcanically and seismically active areas on Earth.
