A study reveals the chemical makeup of the Chicxulub asteroid that collided with Earth and resulted in the extinction of nearly all dinosaurs 66 million years ago.

But researchers have found hard evidence of an asteroid impact that had a cataclysmic effect on the Earth's climate, along with asteroid-specific minerals like iridium at the crater in Chicxulub ...

The iridium-rich layer is known as the K/Pg boundary, and a similar metal in the same rocks has provided the geological fingerprint for where the asteroid came from. The key metal is ruthenium.

The impact released as much energy as 100 million nuclear bombs, gouging a 200-kilometer-wide, 20-kilometer-deep scar in Earth’s crust and unleashing monstrous earthquakes, tsunamis and firestorms.

Asteroid impacts represent a formidable natural phenomenon with the capacity to alter Earth’s environment on both local and global scales. The collision of near‐Earth objects (NEOs) with our ...

Scientists have pinpointed the origin and composition of the asteroid that caused the mass extinction 66 million years ago, revealing it was a rare carbonaceous asteroid from beyond Jupiter ...

One of the ways that we know about this extraordinary event comes from what is known as the Cretaceous-Paleogene (K-Pg) boundary, formerly the Cretaceous-Tertiary (K-T) boundary.
