When James Cook First Crossed the Antarctic Circle

On 17 January 1773, the two ships became the first known vessels to cross the Antarctic Circle. Commanded by James Cook and Tobias Furneaux, the expedition was searching for the supposed southern continent, but what the sailors encountered instead was a vast, hostile seascape of fog, ice and bitter cold

Ancient Wildfires Shaped Antarctic Peatlands 90 Million Years Ago

Antarctica is synonymous with ice today, but during the Late Cretaceous, around 90 million years ago, the continent looked dramatically different. New research led by scientists from the Alfred Wegener Institute has revealed that wildfires regularly burned in forests growing close to the South Pole, making them the southernmost known wildfires ever identified on Earth.

Half a Century of Satellite Data Reveals Massive Polar Ice Loss

The most comprehensive assessment yet of changes in the world's polar ice sheets, led by researchers from Northumbria University and supported by NASA, combined evidence from 42 independent satellite surveys spanning more than five decades. The findings show that the two ice sheets lost an estimated 11,309 billion tonnes of ice between 1979 and 2023.

The Ross Sea May Be Fixing Carbon in the Dark

When most people think about ocean carbon uptake, they picture microscopic plants near the sea surface using sunlight to convert carbon dioxide into organic matter through photosynthesis. However, new research suggests that microorganisms living deep beneath the Ross Sea are helping to capture carbon in complete darkness.

Glass Eyes Beneath the South Pole

During the 2025-26 Antarctic summer season, the international IceCube collaboration completed a major upgrade of the IceCube Neutrino Observatory at the South Pole. The new equipment is expected to improve the observatory’s ability to detect low-energy neutrinos, elusive particles that can travel across the cosmos largely unaffected by matter.
