Crack across Pine Island Glacier
In mid-October 2011, NASA scientists working in Antarctica discovered a massive crack across the Pine Island Glacier, a major ice stream that drains the West Antarctic Ice Sheet.
Searching for Meteorites in Antarctica
Where is the best place on Earth to find meteorites? Although meteors fall all over the world, they usually just sink to the bottom of an ocean, are buried by shifting terrain, or are easily confused with terrestrial rocks.

This is what Antarctica looks like without the ice
Scientists have made a detailed map of Antarctica’s rock bed — what the land looks like underneath the ice — as part of their attempt to predict how the continent might respond to global warming. Figuring out what will happen when Antarctic ice melts requires an understanding of what’s going on down below.
South Shetland Islands and Antarctica
The inclined equatorial orbit of the International Space Station (ISS) limits astronauts to nadir views of Earth—looking straight down from the spacecraft—between approximately 52 degrees North latitude and 52 degrees South. However, when viewing conditions are ideal, the crew can obtain detailed oblique images—looking outwards at an angle—of features at higher latitudes, such as Greenland or, in this image, Antarctica.
Birth of an Iceberg (video)
Flying over Antarctica’s Pine Island Glacier in a DC-8 research plane, scientists participating in NASA’s IceBridge mission made a startling discovery on October 14: a massive crack running about 29 kilometers (18 miles) across the glacier’s floating tongue. The rift is 80 meters (260 feet) wide on average and 50 to 60 meters (165 to 195 feet) deep, and it marks the moment of creation for a new iceberg that will span about 880 square kilometers (340 square miles) once it breaks loose from the glacier.
First complete map of Antarctic Ice Flow (video)
NASA-funded researchers have created the first complete map of the speed and direction of ice flow in Antarctica. The map, which shows glaciers flowing thousands of miles from the continent’s deep interior to its coast, will be critical for tracking future sea-level increases from climate change. The team created the map using integrated radar observations from a consortium of international satellites.
Midwinter’s Greetings in Antarctica
June 21, 2011 marks the winter solstice throughout the Southern Hemisphere. In Antarctica, this day is a turning point when people begin to think about the coming summer and the end of the austral night. Throughout the continent celebrations are held as they have been since the early days of exploration, and messages of good will circulate among the stations.
Concordia station in Antarctica
They are more cut off than the crew of the International Space Station. They are at Concordia in Antarctica, and one of them is ESA researcher Eoin Macdonald-Nethercott. If you want to follow in his footsteps, ESA is looking for his successor.

Strange benthic microbial mats in Antarctica
Photosynthetic microbial mats forming large conical structures up to half a meter tall have been discovered by astrobiologists in Lake Untersee, Antarctica. This research is described in a forthcoming article in the journal Geobiology. Photo copyright: Dale T. Andersen 2011.
