Bird’s-eye view of Antarctic ice loss
Satellite images of Antarctica between 1992 and 2006 indicate that the continent was losing ice much faster at the end of that period than it was a decade before.

Hidden Depths: Antarctic krill startle deep-ocean scientists
The first camera lowered 3,000 meters to the seabed off the coast of Antarctica videoed what biologists identify as the supposedly upper-ocean species of Antarctic krill.

In the Beginning: More early clues for life at home, out there
Astronomers move closer to understanding how life arose on Earth and how it could arise elsewhere.

Climate fix could deplete polar ozone
Scientists seeking to cool Earth’s climate by injecting sulfuric acid droplets high in the atmosphere might trim rising temperatures but could also destroy much of the ozone in polar regions, a new study suggests.

Climate clues in ice
A kilometers-long ice core from Antarctica has been recording climate information for the past 800,000 years and has revealed a three millennia–long period when carbon dioxide levels in the air were lower than any previously measured.

Slip, Slide, Shake
Analyses of GPS and seismic data about one of Antarctica’s largest and most dynamic glaciers provide new insights into the ice stream’s lurching march to the sea.

Ancient burrows
Triassic-era sediments unearthed in Antarctica reveal the well-preserved lair of a four-legged, mammal-like reptile.

Unintended consequences
A full recovery of the ozone hole over Antarctica in the coming years could significantly boost warming of the atmosphere over and around the icy continent.

Martian soil hints at water, nutrients
The first chemical analysis of dirt by the Mars Phoenix Lander supports the notion that liquid water flowed on the Red Planet at some point.
