Scientists have identified a massive fan-shaped structure connecting several basins beneath East Antarctica, likely formed during the breakup of the supercontinent Gondwana.

A newly listed Science paper points to upper-mantle seismic activity beneath East Antarctica, highlighting a research topic with major geophysical implications.

Researchers say the eastern ice shelf of Antarctica’s Thwaites Glacier is likely to break up in 2026, removing a critical buttress from one of the planet’s most vulnerable ice masses.

NASA’s balloon-borne PUEO mission has completed a 23-day Antarctic flight using the ice sheet as an enormous detector in the search for ultrahigh-energy neutrinos and cosmic-ray signals.

Researchers say traces of iron-60 in Antarctic ice preserve a record of the Solar System’s movement through the Local Interstellar Cloud and its possible connection to ancient supernova activity.

Researchers analyzing Antarctic ice cores found changing levels of iron-60 over the last 80,000 years, strengthening the case that Earth is currently being dusted by material preserved in the Local Interstellar Cloud.

Fresh NASA Earth Observatory imagery shows von Karman vortex streets forming downwind of Peter I Island, a rare atmospheric display shaped by strong Southern Ocean winds and the island’s icy volcanic mass.

The IceCube Observatory’s more than 5,000 light sensors buried in Antarctic ice help detect high-energy neutrinos, offering clues about the universe’s most extreme events.

A new PNAS study links Antarctica’s abrupt sea ice decline after 2015 to a reversal in ocean conditions, with under-ice observations showing how trapped subsurface heat was suddenly released.

The IUCN has declared emperor penguins endangered, linking the status change to climate change and mounting extinction risk in Antarctica.

Mysterious Jurassic-era pink granite boulders in Antarctica's Hudson Mountains have guided researchers to the discovery of a massive granite body buried beneath Pine Island Glacier, spanning nearly 100 kilometers wide and 7 kilometers thick.

Satellite analysis reveals Antarctica has lost nearly 5,000 square miles of grounded ice in 30 years as warming ocean waters drive retreat.
