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.

The asteroid that wiped out dinosaurs after slamming into the Earth 66 million years ago is believed to have come from beyond Jupiter, a new study says.

Dinosaur-Killing Asteroid Had an Accomplice, Study Suggests A second impact crater from the same time period as the Chicxulub crater shows the rock that wiped out the dinosaurs wasn't working alone.

Buried "megaripples" — some the size of five-story buildings — are helping scientists piece together the devastation following the impact that wiped out the nonavian dinosaurs.

The space rock that wiped out the dinosaurs 66 million years ago was a rare strike from an asteroid beyond Jupiter, a new study details.

A new study sheds light on some unlikely survivors of the asteroid impact that wiped out most dinosaurs 66 million years ago: night lizards. According to research published Wednesday in Biology ...

A new study from researchers claims to have pinpointed where the dinosaur-killing asteroid originated, and that it wasn't a comet.

By Kate Golembiewski, CNN (CNN) — Sixty-six million years ago, the story of life on Earth took a dramatic turn when an asteroid collided with what’s now the Yucatán Peninsula in Chicxulub ...

The space rock that wiped out the dinosaurs 66 million years ago was a rare strike from an asteroid beyond Jupiter, a new study details. The finding pins down the nature of the fateful space rock ...

Therefore, the asteroid that killed the dinosaurs was probably a carbonaceous chondrite, an ancient space rock that often contains water, clay and organic (carbon-bearing) compounds.
