Antarctica

Thick ice isolates a hidden ocean cavity from the furious winds and freezing air temperatures of Antarctica. But nothing stops the tides.

Antarctica was home to a temperate, swampy forest about 90 million years ago.

Blood-red algae is blooming in Antarctica, leading to plains of creepy 'watermelon snow' across Galindez Island.

Antarctica saw two record-high temperatures set between Feb. 6 and Feb.9, and that took a huge toll on the continent's ice, as seen in NASA images.

A research station off Antarctica's northern tip just reported a new record-high temperature of 69.35 degrees Fahrenheit (20.75 degrees Celsius).

For the first time, an underwater robot visited the bottom of Antarctica's Thwaites Glacier.

A robotic submarine is about to descend into a dark, water-filled cavern in Antarctica, to try to find out why one of the continent's largest glaciers is melting so fast.

Scientists are scouring the remote Antarctic ice cap for rare meteorites chock-full of iron and holding secrets to the history of our solar system going back some 4.5 billion years.

Two large rifts have widened near the edge of Pine Island Glacier on the West Antarctic ice sheet. If they continue to grow, they could release an iceberg four times bigger than Manhattan.

Antarctica's ice shelves are under attack at their most vulnerable points.

A huge lake of sizzling hot lava has been discovered in a volcano on a remote sub-Antarctic island in the South Atlantic Ocean.

A remote science station in Antarctica forced to close over the polar winter by a dangerous ice chasm is completely empty of human life.

The bizarre holes have been popping up sporadically in the sea ice since the 1970s.

The potential for the Ross ice shelf in Antarctica to collapse is determined by a newly discovered rock boundary running right down the middle of the ice.
