How the sun caused an aurora this week

On the evening of Aug. 20, 2014, the International Space Station was flying past North America when it flew over the dazzling, green blue lights of an aurora. On board, astronaut Reid Wiseman captu...

Ozone-depleting compound persists, NASA research shows

NASA research shows Earth's atmosphere contains an unexpectedly large amount of an ozone-depleting compound from an unknown source decades after the compound was banned worldwide.<img src="http:...

New satellite data will help farmers facing drought

NASA's Soil Moisture Active Passive (SMAP) satellite mission, scheduled to launch this winter, will collect the kind of local data agricultural and water managers worldwide need. SMAP uses two micr...

Life can persist in cold, dark world: Life under Antarctic ice explored

The first breakthrough article to come out of a massive U.S. expedition to one of Earth's final frontiers shows that there's life and an active ecosystem one-half mile below the surface of the West...

Record decline of ice sheets: Scientists map elevation changes of Greenlandic and Antarctic glaciers

Researchers have for the first time extensively mapped Greenland's and Antarctica's ice sheets with the help of the ESA satellite CryoSat-2 and have thus been able to prove that the ice crusts of b...

Nuclear magnetic resonance experiments using Earth's magnetic field

Earth's magnetic field, a familiar directional indicator over long distances, is routinely probed in applications ranging from geology to archaeology. Now it has provided the basis for a technique ...

Neither too hot nor too cold: Evolution of marine crocodilians constrained by ocean temperatures

The ancestors of today's crocodiles colonized the seas during warm phases and became extinct during cold phases, according to a new Anglo-French study which establishes a link between marine crocod...

Why global warming is taking a break

The average temperature on Earth has barely risen over the past 16 years. Researchers in Switzerland have now found out why. And they believe that global warming is likely to continue again soon.&l...

Study of African dust transport to South America reveals air quality impacts

A new study that analyzed concentrations of African dust transported to South America shows large seasonal peaks in winter and spring. These research findings offer new insight on the overall human...

Minor variations in ice sheet size can trigger abrupt climate change

Small fluctuations in the sizes of ice sheets during the last ice age were enough to trigger abrupt climate change, scientists have found. The team compared simulated model data with that retrieved...
