Yucatan's Chicxulub crater marks one of our universe's most momentous historical events: when an asteroid strike killed 75% ...

The 5.3-mile-wide crater is now confirmed to be 66 million years old, suggesting that the impact of at least two giant space rocks preceded the mass extinction of dinosaurs.

And because the crater appeared to be the same age as the global rock layer enriched with asteroid dust, researchers were fairly certain they had the story of the dinosaurs’ demise figured out.

Roughly 35 million years ago, a massive asteroid slammed into the Atlantic Ocean near what’s now the East Coast. The impact ...

A previously undiscovered asteroid crater off the coast of West Africa may hold some answers about how Dinosaurs went extinct. Approximately 66 million years ago, a large asteroid, whose crater is ...

The Chicxulub crater, located off the coast of the Yucatán Peninsula in Mexico, is one of the most significant geological sites on Earth. It marks the catastrophic impact of a massive asteroid or ...

No, it’s not that asteroid, the one that doomed the dinosaurs to extinction, but a previously unknown crater 248 miles off the coast of West Africa that was created right around the same time.

"The Nadir Crater is an incredibly exciting discovery of a second impact close in time to the Cretaceous-Paleogene extinction," said Sean Gulick, an impact expert at the University of Texas at Austin.

Asteroid Day reminds us of space rocks' power. Some asteroids hit Earth hard. One exploded over Chelyabinsk in 2013, injuring ...

According to scientists who maintain that dinosaur extinction came quickly, the impact must have spelled the cataclysmic end. ... This 150-kilometer-wide crater lies just off the Yucatan peninsula.

Dinosaurs roamed the earth for 165 million years and went extinct 66 million years ago. These two theories may explain why. Hotspots ranked Start the day smarter ☀️ Funniest cap messages Get ...

Whether volcanic activity played a major role in the dinosaur extinction remains up for debate, but the German researchers did find evidence to rule out that the impactor could have been an icy comet.
