Mountains preserve evidence of ancient oceans, moving continents and tectonic processes that have shaped Earth over millions of years. Later deformation, erosion and burial, however, can obscure important parts of this geological record. An international research team led by Istanbul Technical University (ITU) has identified evidence of a previously unrecognized Late Cretaceous continental magmatic arc in northwestern Iran.

Earth’s center is moving, and NASA just measured it
Earth’s center of mass is constantly on the move, shifting by a few millimeters as enormous amounts of water, ice, and even air migrate around the planet with the seasons. NASA scientists have developed a more precise way to track these tiny swings using laser-ranging satellites,

A meteor hit Oklahoma 100 million years later than scientists thought
A meteor crater buried beneath Oklahoma has turned out to be nearly 100 million years younger than scientists thought. Zircon crystals show the Ames impact occurred about 370 million years ago, meaning it was not part of the mysterious Ordovician bombardment once linked to a poss
