The pristine samples from asteroid Ryugu returned by the Hayabusa2 mission on December 6, 2020, have been vital to improving the understanding of primitive asteroids and the formation of the solar system. The C-type asteroid Ryugu...
Researchers at the universities of Amsterdam and Utrecht have observed the formation of nanocavities in montmorillonite clay under exposure to gamma-aminobutyric acid, a molecule commonly found on meteorites. This hitherto unrecognized phenomenon could be relevant to...

Cretaceous fossil from Antarctica reveals earliest modern bird

Sixty-six million years ago, at the end of the Cretaceous Period, an asteroid impact near the Yucatán Peninsula of Mexico triggered the extinction of...

How is Antarctica melting, exactly? Crucial details are beginning to come into focus

The size of the Antarctic ice sheet can be hard to comprehend. Two kilometers thick on average and covering nearly twice the area of...

Melting sea ice in Antarctica causes ocean storms, scientists say

The record-breaking retreat of Antarctic sea ice in 2023 has led to more frequent storms over newly exposed parts of the Southern Ocean, according...

New discovery suggests significant glacial retreat in West Antarctica began in 1940s

Among the vast expanse of Antarctica lies the Thwaites Glacier, the world's widest glacier measuring about 80 miles on the western edge of the...

Antarctica risks ‘cascades of extreme events’ as Earth warms, study says

Extreme weather in Antarctica, including ocean heat waves and ice loss, is set to become more intense unless urgent policy action reduces the burning...

Antarctica sea ice melts to a record low

The Antarctic Ocean area covered by ice has shrunk to a record low, exposing the thicker ice shelves buttressing Antarctica's ground ice sheet to...

17-pound meteorite discovered in Antarctica

Antarctica is a tough place to work, for obvious reasons—it's bitterly cold, remote, and wild. However, it's one of the best places in the...

Antarctica’s emperor penguins could be extinct by 2100

Greater conservation efforts are needed to protect Antarctic ecosystems, and the populations of up to 97% of land-based Antarctic species could decline by 2100...

Scientists map heat beneath Antarctica’s icesheets

Researchers from the ARC Center for Excellence in Antarctic Science (ACEAS) at the University of Tasmania are helping predict future sea level rise by...

Antarctica’s ice shelves could be melting faster than we thought

A new model developed by Caltech and JPL researchers suggests that Antarctica's ice shelves may be melting at an accelerated rate, which could eventually...

Ice core taken in Antarctica contains sample of atmosphere from five million years ago

A team of researchers affiliated with multiple institutions in the U.S. has successfully pulled an ice core from Antarctica's Ong Valley that contains samples...

Antarctica’s only active volcano shows how CO2 allows volcanoes to form persistent lava lakes at the surface

Antarctica has long been a land of mystery and heroic feats made famous by the explorations of James Ross, Roald Amundsen, Robert Scott and...
