Brian Choo/Smithsonian MagazinePaleontologists recently uncovered a bone fragment from a species of bony-toothed sea birds, called pelagornithids, that might be the largest flying bird ever discovered. Where an albatross has a wingspan of about 10-12 feet, those of the pelagornithid reached up to 20. The bird also had a terrifying…

A new international study led by Monash University climate scientists has revealed that ice loss in Antarctica persisted for many centuries after it was initiated and is expected to continue. “Our study implies that ice loss unfolding in Antarctica today is likely to continue unabated for a long time —…

A dead Soviet satellite and a discarded Chinese rocket body seem to have avoided a collision on Thursday night, after satellite-tracking company LeoLabs calculated a 10% chance they would crash. It was impossible to intervene to prevent a collision, since both objects are dead and can't be maneuvered. Satellite collisions…
