Asteroid 2025 TF passed over Antarctica at 00:47:26 UTC ± 18 seconds on October 1, coming within 428 ± 7 km of Earth's surface. That distance is nearly the same as the orbit of the International Space Station (approx. 370 -- 460 km). Measuring about 1 to 3 meters in…

One week ago, an asteroid flew so close to Earth that it nearly broke the record for the closest asteroid approach ever. This space surprise came to astronomers’ attention on Wednesday, October 1, 2025, when the Catalina Sky Survey in Arizona spotted an asteroid named 2025 TF a few hours…

Ernest Shackleton's ship Endurance wasn't reinforced for navigating Antarctic ice, a new study suggests. Shackleton was aware of the ship's shortcomings.

Once considered Earth’s last frontiers, the Arctic and Antarctic regions tested human limits like no other. The Endurance expedition of 1915 remains one of history’s greatest survival stories, an enduring testament to resilience and the will to live against impossible odds. Though celebrated for its strength, the ship was ultimately…

The near-Earth asteroid 2025 TF (red crosshairs) came about as close to Earth as the International Space Station on Wednesday (Oct. 1), evading detection until hours later. (Image credit: ESA / Las Cumbres Observatory) A small asteroid zoomed past Earth closer than most satellites last week — and astronomers didn't…

The remains of the Endurance, which sank in 1915 Science History Images / Alamy It has been 110 years since Endurance, often described as the strongest wooden ship ever built, sank after becoming trapped in sea ice near Antarctica. But a reassessment of the evidence reveals that Endurance was actually…

Melting ice sheets in Antarctica will raise sea levels DurkTalsma/Getty Images Antarctica may have passed a climate tipping point of no return, scientists are warning, with mounting evidence that a sudden slump in sea ice formation since 2016 is linked to human-induced ocean warming. For decades, Antarctic sea ice levels…

Right now, cold air high above Antarctica is up to 35ºC warmer than normal. Normally, strong winds and the lack of sun would keep the temperature at around –55°C. But it’s risen sharply to around –20°C. The sudden heating began in early September and is still taking place. Three separate…
