King of the dinosaurs, late Cretaceous apex predator of western North America
Sotheby’s has sold a 67‑million‑year‑old Tyrannosaurus rex skeleton nicknamed “Gus” for $50.1 million, the highest price ever paid for a dinosaur at auction. The specimen, about 61–63% complete, was excavated in South Dakota from 2021–23; scientists are warning that private ownership will restrict research access.
A new study explores defending Earth from large near-Earth asteroids. It analyzes a crater-based nuclear detonation approach, noting timing is critical and early warning is essential. Researchers say this method could be the most effective for very large rocks with short warning times, though it requires complex missions.
