Throughout Earth's 4.5-billion-year lifetime massive supervolcanoes have erupted. However, despite the claims of those who fear 2012,there’s no evidence that such a supereruption is imminent.
FASTSAT has painted a detailed picture of the dynamic region around Earth, showing a host of interrelated phenomena -- such as electric currents and outflowing particles occurring together.
Researchers created a model to predict the severity and geographic distribution of fires in the Amazon rain forest and the rest of South America months in advance.
The Advanced Technology Microwave Sounder on board NASA's newest Earth-observing satellite, NPP, acquired its first low-atmosphere moisture measurements on November 8, 2011.
A multidisciplinary, international team of researchers is heading this month to an isolated edge of Antarctica, Pine Island Glacier, to determine how the ocean is melting away the glacier’s underbelly.
It's not just the CFCs of the 1970s and '80s that can deplete the ozone layer; climate-changing greenhouse gases can also affect it.
Multi-year NASA airborne campaign to study the humidity and chemical composition of the tropical tropopause over the Pacific Ocean in 2013-2014.
As the only large-scale, ongoing survey of the elevation of Antarctica's ice sheet, IceBridge is beginning to return its own record of the continent's changing ice cover.
Winter weather doldrums are more frequent in the decades that the North Atlantic is abnormally warm, a new NASA study finds. These stagnant weather episodes, called atmospheric blocking events, can influence ocean circulation.
Embark upon a geographical adventure with MISR's Mystery Image Quizzes, designed to inspire understanding of the processes that affect Earth.
On a bluff overlooking the Atlantic, Grady Koch spent a month watching ocean winds.
NASA's Operation IceBridge makes the first-ever detailed airborne measurements of a major iceberg calving in progress at Pine Island Glacier in Antarctica.
A late October snowstorm from a Nor'easter blanketed the eastern U.S. from West Virginia to Maine and broke records the weekend before Halloween Monday
The mission of Suomi NPP is to foster the understanding, monitoring and prediction of long-term climate change and short-term weather conditions
NASA's IceBridge team has seen a large -- and unexpected -- crack running across Pine Island Glacier, one of the largest and fastest-moving glaciers in Antarctica.
A technological trailblazer is poised to lift off from a California launch pad to take a place in space to show us what is happening on Earth.

This year's Antarctic ozone hole, which yawns wide every Southern Hemisphere spring, was the ninth largest on record.
The Earth's thinning ozone layer is synonymous with a singing and dancing seagull named Sid -- at least it is in New Zealand and Australia.
