Solar scientists have the best seat in the house as the Sun's stormy season approaches its zenith. The largest coordinated fleet of spacecraft and ground observatories ever assembled is helping to predict the impact of turbulent space weather.

Scientists are excited about the quality of the first images from NASA's Earth Observing-1 spacecraft.

New satellite rain maps reveal a more accurate picture of how much rain falls in the tropics. The maps from NASA's TRMM mission may provide clues to developing El Niños and La Niñas.

The West Antarctic Ice Sheet's contribution to global sea-level rise may be much slower today than it was in the past. New evidence indicates that the ice sheet may not have been as big or as steady a source of sea-level rise as scientists thought.

A new study may give scientists their first global picture of the extent of unique "iron-limited" ocean regions.

Scientists expect that recovery of the Arctic ozone layer may be slower than previously expected. Low temperatures have recently increased ozone losses over the Arctic despite the phase out of ozone-destroying chemicals.

Earth comes in for its close-up with the "zoom lens" on NASA's Terra satellite. Images from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) are now are available to the public.
