Around 2.5 million years ago, an asteroid may have exploded over Antarctica.
The evidence comes from a chemical analysis of more than 100 tiny pieces of rock entrained within the White Continent’s ice, researchers report in the Feb. 1 Earth and Planetary Science Letters. The timing makes the midair detonation the oldest known airburst, the team says. Only two other ancient airburst events are known in the geologic record, dating to 480,000 and 430,000 years ago (SN: 3/31/21
In March 2020, Sam Cox was on a military exercise in the sweltering heat of Brunei.
When he’d left, Covid was barely making news and he had no idea what was happening in the world beyond the jungle.
But within days, Sam went from a life packed with activity to being stuck on the sofa during a national lockdown.
While most of us were sat on the sofa watching Tiger King, Sam got to work planning a record-breaking expedition across
A mysterious “pyramid” has been spotted below the ice in Antarctica, sparking a frenzy online among conspiracy theorists.
The formation was located using satellite images taken over the southern part of Antarctica’s Ellsworth Mountain range.
The location in question is found at the coordinates 79°58’39.25?S 81°57’32.21?W, which has been a much-searched spot on Google Earth.
A number of peaks can been seen appearing to push through the snow – with one even measuring two kilometers in each direction of its

In September 2022, two months before PhD student Megan Kerr was scheduled to board a military plane bound for the Antarctic ice sheet, she found herself in a conference room on Oregon State University’s campus, waiting to ask a question that had been nagging her
Talk about the observer effect! Scientists studying microplastic contamination in remote Antarctica found a significant amount actually came from their own ship.
University of Basel-led experts filtered eight million litres of water from the remote Weddell Sea to determine the levels and origins of microplastic contamination.
The team studied 101 particles in detail, and found that 89 per cent came from their own ship.
The findings suggest that shipping is a key driver of Antarctic plastic pollution, and highlight the
A total solar eclipse which took place over Antarctica on Saturday morning has been revealed in stunning photos, taken by a few of the lucky viewers who witnessed it from the southernmost continent.
The rare spectacle of the moon blocking out the sun reached its greatest extent at around 07:33 GMT for spectators near the edge of Antarctica’s Ronne Ice Shelf, which was plunged into darkness for two minutes.
The eclipse provided a short respite from the long summer’s day
A pristine 1956 Porsche 356A today could be worth in excess of £200,000.
But instead of preserving the classic German sportscar, one racer has converted hers into a snowmobile.
Renée Brinkerhoff, an American philanthropist racing driver, is preparing for the final stage of her Project 356 World Rally Tour in Antarctica, which involves sprinting in her vintage Porsche across the most extreme terrain yet.
Fitted with snowtracks at the rear and a pair of skis at the front, the 65-year-old
