Sensors on three NASA science aircraft recorded data on water fluctuation between soil and the atmosphere over California's San Joaquin Valley.
Given the vastness of space and the long times between supernovae, astronomers can say with certainty that there is no threatening star close enough to hurt Earth.
By 2100, climate change will bring big changes to Earth's ecosystems, with many plants and animals facing increasing competition for survival, finds a new NASA/Caltech study.
An animation showing the onset and movement of rainfall from Washi was created by Dr. Zhong Liu, at the Goddard Earth Sciences Data and Information Services Center at NASA Goddard Space Flight Center in Greenbelt, Md.
New research into Earth's climate history suggests there is potential for rapid climate changes this century if global warming is not abated.
The study, focusing on Quebec, is one of the first to present a detailed view of how warmer temperatures are influencing plant distribution and density in northern areas of North America.
TIMED has collected data over almost an entire solar cycle, which lasts about 11 years, creating a new picture of Earth's environment as well as how it responds to changes in the sun.
Heat pouring off an ancient (and still active) volcano fuels Yellowstone's famous hot springs, mud pots, terraces and geysers, including Old Faithful.
In Greek mythology, Jason embarked on an epic quest for the Golden Fleece. Today, NASA's modern-day Jason-1 achieves its own heroic status, marking its 10th birthday.
NASA and Ohio State University researchers have discovered the major tsunami generated by the March 2011 Tohoku-Oki quake centered off northeastern Japan was a long-hypothesized "merging tsunami."
A new study using data from a NASA-built Landsat shows that Kirtland's warblers like to live in young forests and often forests that have been on fire.

Record-breaking drought in Texas has reduced groundwater levels in much of the state to the lowest levels seen in more than 60 years.
Earth's magnetic field has flipped its polarity many times over the millennia -- but this causes no dramatic effects, and will not lead to problems in 2012.
Lightning bursts create electromagnetic waves that circle around Earth creating a low frequency wave called Schumann resonance. These have now been detected in space and can be used to study our atmosphere.
