'Broken Heart' Image the Last for NASA's Long-Lived Polar Mission
04.28.08 -- NASA's Polar satellite concluded its successful 10-year mission with a breathtaking image of the colorful dancing lights of an aurora.
Release
NASA Launches Airborne Study of Arctic Atmosphere, Air Pollution
04.01.08 -- This month NASA begins the most extensive field campaign ever to investigate the chemistry of the Arctic's lower atmosphere. The mission is poised to help scientists identify how air pollution contributes to climate changes in the Arctic.
Feature
Researchers Say Arctic Sea Ice Still at Risk Despite Cold Winter
03.19.08 -- Using the latest satellite observations, NASA researchers and others report that the Arctic is still on 'thin ice' when it comes to the condition of sea ice cover in the region.
Feature
Greenland's Rising Air Temperatures Drive Ice Loss at Surface and Beyond
02.20.08 -- A new NASA study confirms that the surface temperature of Greenland's massive ice sheet has been rising, fueling the loss of the island's ice at the surface and throughout the mass beneath.

Signs of Summer Thaw on the Antarctic Peninsula
02.06.08 -- The tip of the Antarctic Peninsula showed seasonal changes in late January 2008. Images captured on Jan. 24 and Jan. 30 by the Moderate Resolution Imaging Spectroradiometer on NASA's Terra satellite show a dramatic color shift, signs of the summer thaw.

Retreat of the Tasman Glacier
01.25.08 -- The Tasman Glacier, New Zealand's longest, is one of 12 that may not recover from recent melting. In November 2007, New Zealand's government announced that ice volume in the country's Southern Alps had shrunk nearly 11 percent over the previous 30 years.

Cloud Streets Across Caspian Sea
01.11.08 -- South of the loosely packed ice in the northern part of the sea, parallel rows of clouds line up along the north-south axis of the wind. These clouds form when cold air blows over the warmer, moister air that sits over the water.
Feature
Scientific Balloons Achieve Antarctic Flight Record
01.04.08 -- NASA and the National Science Foundation have achieved a new milestone in conducting scientific observations from balloons, by launching and operating three long-duration flights within a single Antarctic summer. Scientists are using the balloons to investigate the nature of ultra-high-energy cosmic rays and to search for antimatter.
Multimedia
Pine Island Glacier, Antarctica
01.04.08 -- Satellite observations over the past few decades show that the Antarctic's Pine Island Glacier has lost elevation. This image of Pine Island Glacier from the Landsat Image Mosaic of Antarctica, otherwise known as LIMA, shows the glacier since a big calving event.
