Pieces of sea ice drift near Antarctica's Danger Islands in this image, acquired on Jan. 22, 2023, by the Landsat 8 satellite. Several of the islands are stained pink by guano from Adélie penguins with a krill-rich diet. (Image credit: NASA Earth Observatory/Michala Garrison) The diets of penguins on Antarctica's Danger…

Concordia is considered the most isolated field station in the world. (Image credit: GUY CLAVEL/AFP via Getty Images) While millions around the world grappled with extreme heat this month, a research station in Antarctica recorded Earth's coldest temperature since 2012. The high-altitude research station, named Concordia, logged a low of…

It’s easy not to instantly recognize what the picture above shows. It appears to depict a distorted hummingbird-style shape, but it’s actually a stream of ice moving slowly around a mountain in East Antarctica from above.  The image was captured by a satellite program that launched last year as a…

The obstruction causes stresses in the ice,…

As of July 20, the public can access data from the two powerful radar instruments aboard the NISAR (NASA-ISRO Synthetic Aperture Radar) satellite. Teams in the United States and India will release files processed from the satellite’s L-band and S-band radars on an ongoing basis, helping researchers and other users…

Scientists have uncovered evidence for hundreds of previously undetected glacial earthquakes in Antarctica, with most occurring near the rapidly changing Thwaites Glacier.

Antarctica froze over 34 million years ago, when the planet was around 9 degrees Fahrenheit (5 degrees Celsius) warmer than today, while the Northern Hemisphere did not form large ice sheets for more than 20 million years after that. Falling carbon dioxide levels were known to play a role, but…

A small fossil collected on an Antarctic island more than four decades ago is a tail vertebra of a titanosaurian sauropod dinosaur that roamed Antarctica roughly 83 million years ago, according to a new paper in the journal Acta Palaeontologica Polonica. The discovery represents only the second sauropod body fossil…

The first dinosaur found in Antarctica belonged to a group that included the largest animals ever to walk the planet, a new study finds. A backbone from the 82 million-year-old giant was discovered more than 40 years ago, but at the time, researchers assumed it came from an ancient marine…
