Zhamanshin Crater Likely ~26.5 km, Rewriting Its Climate Impact

A new high-resolution topographic analysis suggests the Zhamanshin impact crater in Kazakhstan is about 26.5 km in diameter—roughly double previous estimates—meaning the energy released could be 7–10 times greater and potentially linked to abrupt environmental changes around 900,000 years ago; erosion and loess conceal outer rings, so further regional climate records are needed to assess any biological or climate effects, with implications for planetary protection and future planetary exploration.

Unveiling the North Sea's Hidden Glacial Landscapes

Researchers have discovered well-preserved glacial landforms buried beneath the North Sea, using seismic data to reveal features from about 1 million years ago. These findings, published in Science Advances, highlight how past ice sheets responded to climate changes during the Mid-Pleistocene Transition, offering insights into current climate change impacts. The study utilized 3D seismic technology, originally developed for oil and gas exploration, to map these ancient landscapes, which include features carved by ice sheets and ocean currents, reshaping our understanding of the North Sea's glacial history.
