happened to collide with the Earth. The best-known episode is that in which the dinosaurs died 65 million years ago, but there have been many other catastrophic impacts both before then, and since.

Researchers have made a new discovery that changes our understanding of Earth's early geological history, challenging beliefs about how our continents formed and when plate tectonics began. A study ...

Since the beginning of Earth's history, tiny particles of rock and metal from space have been hitting our planet. On clear nights, we can even see their traces as shooting stars. Trapped in layers of ...

NASA’s Carruthers mission will film Earth’s elusive exosphere to understand space weather, atmospheric escape, and planetary habitability. A NASA mission aims to photograph a feature of Earth that is ...

Deep beneath our feet, at a staggering depth of over 5,100km, lies Earth's inner core — a solid ball of iron and nickel that plays a crucial role in shaping the conditions we experience on the surface ...

Models of North China Craton deformation since the middle Jurassic, showing phases of flat slab subduction (a, b) and rollback (c, d). Key: overriding plate (O), downgoing plate (D), trench (T), ...

In just under half a decade, a 1,000-foot-wide (305-meter-wide) asteroid named after the Egyptian god of chaos and destruction, Apophis, will pass within 30,000 miles (48,300 kilometers) of Earth.

Earth's core cannot be made just of iron — it also appears to contain carbon. And our research suggests it may contain a bit of oxygen and possibly silicon as well. When you purchase through links on ...

Continental clues: Modern continental rocks carry chemical signatures from the very start of our planet’s history, challenging current theories about plate tectonics. Researchers have made a new ...
