Antarctica

Mariah Blake, author of "They Poisoned the World: Life and Death in the Age of Forever Chemicals" speaks at Vroman's Bookstore in Pasadena, California - Copyright AFP Robyn Beck Issam AHMED No corner of Earth is untouched. From Tibet to Antarctica, so-called “forever chemicals” have seeped into the blood of…

By July 1858, the English explorer John Hanning Speke had been in Africa for 18 months. His eyes and body were weakened by fever, and he still hadn’t found what he set out to discover – the source of the River Nile. Squinting through the heat on July 30, however,…

Underneath miles-deep ice sheets covering Antarctica lies the largest mountain range no one on Earth has ever seen. Even though a few of its tallest points peek through in some places, relatively few people know of the entire range’s existence. However, geologists studying it have long argued about how and…

And they might be picking the pockets of their neighbors as they go. Using satellite data, researchers have observed a phenomenon called…

Antarctica is home to around 20 million breeding pairs of penguins, like these Adelie penguins near Paulet Island on the Antarctic Peninsula. But what's below the ice these penguins waddle on every day? (Image credit: Patrick J. Endres via Getty Images) From above, Antarctica might seem like a cold, flat…

President Donald Trump has begun eroding the United States presence in Antarctica by announcing deep funding cuts to his nation’s science and logistics on the icy continent. The Trump administration has significantly reduced funding for both Antarctica’s largest research and logistics station, McMurdo, and the National Science Foundation which funds…

There’s a new type of criminal on the loose. They’re big. They’re cold. And they’ve been committing acts of thievery in Antarctica for the past eighteen years. A new study, published in The Cryosphere, reveals that a glacier in Antarctica has been stealing ice from its neighbor. This act of…

A glacier in Antarctica is committing "ice piracy" -- stealing ice from a neighbour -- in a phenomenon that has never been observed in such a short time frame, say scientists.  This activity was previously believed to take place over hundreds or even thousands of years.  However, high-resolution satellite observations…

The chemical composition of a meteorite could shake up scientists' understanding of how Earth got its water. Researchers found signs of hydrogen sulfide in a type of meteorite similar to those that…

Last Updated: May 05, 2025, 11:43 IST When the ice of the glacier melts, it increases the flow of water in the oceans. If all glaciers and ice sheets melted, the global sea level would rise by more than 195 feet. The world's largest iceberg, named A23a, is seen in…
