NASA’s Reel Science Communications Challenge Winners Announced
NASA has selected the winners of NASA’s educational “REEL Science Communications” video contest. The three winning videos were created by students in New Jersey, North Carolina and California. There were also six videos chosen as runners-up.
The three winning videos were “All About Ozone,” produced by Michelle Goffreda and Ananya Joshi of Lincroft, N.J.; “Hurricanes,” by Erik Borchers and Will Reiss of Raleigh, N.C.; and “Ship Tracks,” by Michelle Ko of Pasadena, Calif. Read more
Flooding in LaPlata
In early April 2013, severe flooding claimed more than 50 lives, and forced thousands from their homes in the Buenos Aires region, news sources said. Many of the casualties occurred in La Plata, situated about 60 kilometers (40 miles) southeast of Buenos Aires. Roughly 40 centimeters (16 inches) of rain fell on La Plata in a two-hour period April 2–3, Agence France-Presse reported.
Flood water lingered when the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite captured this image on April 4, 2013. Read more
Mike Ramsey, a professor and vulcanologist at the University of Pittsburgh, is among 22 scientists being featured during April’s Earth Month for Know Your Earth 3.0, Local Connections, a partnership between 22 of NASA’s Earth-observing missions that nominated a scientist or engineer to be featured on NASA websites during April 2013. Ramsey uses data from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on board Terra.
Ice on the Caspian
The Caspian Sea isn’t really a sea but in fact a giant lake that spans roughly 1,000 kilometers (600 miles) from north to south. In the winter, ice often forms over the lake’s northernmost reaches, while the central and southern parts remain ice free. Temperatures are generally lower in the north, so you might guess that the ice owes its existence purely to the higher latitude. But the reality is more complex: From north to south, the Caspian Sea also exhibits differences in salinity and depth. Read more
Dust Storm in Libya
A dust storm blew out of Libya and across the Mediterranean Sea in late March 2013. Southwest of the coastal city of Banghazi (Benghazi), an especially thick dust plume spanned roughly 100 kilometers (60 miles), and the plume was thick enough to completely hide the ocean surface below. Read more
Where the borders of Egypt, Sudan, and Libya meet, a rugged mountain complex rises from the Sahara. The peaks of Jebel Uweinat reach elevations about 2,000 meters (7,000 feet) above sea level. Geologists exploring Jebel Uweinat have found rock layers that are hundreds of millions of years old, preserving traces of landscapes that were very different from the bone-dry environment that prevails here today.

Snow in the Northeastern United States
- Snow cover sprawled across the northeastern United States in early March 2013. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this natural-color image on March 9. Snow cover stretched from West Virginia into Canada, and from the western shore of Lake Ontario to the Atlantic Ocean. Read more
Four Erupting Volcanoes on the Kamchatka Peninsula
Russia’s Kamchatka Peninsula has the highest concentration of active volcanoes on Earth. Separated by only 180 kilometers (110 miles), Shiveluch, Bezymianny, Tolbachik, and Kizimen were all erupting simultaneously on January 11, 2013.
The activity of these four volcanoes was captured during a single orbit by the Advanced Spaceborne Thermal Emission and Reflection Radiometer on NASA’s Terra satellite. The four false-color (near infrared, red, and green) images above show Shiveluch, Bezymianny, Plotsky-Tolbachik, and Kizimen in detail. Read more
Unusual Cold in China and Northeast Asia
Between late November 2012 and early January 2013, China recorded its lowest temperatures in 28 years. In northeastern China, air temperatures dipped to -15.3°Celsius (4.5°Fahrenheit), according to the state news agency Xinhua. Frigid temperatures and blizzards stranded air and rail passengers, killed roughly 180,000 cattle, and forced authorities to open hundreds of shelters. Read more
Air Quality Suffering In China
Residents of Beijing and many other cities in China were warned to stay inside in mid-January 2013 as the nation faced one of the worst periods of air quality in recent history. The Chinese government ordered factories to scale back emissions, while hospitals saw spikes of more than 20 to 30 percent in patients complaining of respiratory issues, according to news reports.
