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 suspected 6-mile-wide (10-kilometer) asteroid was a rare carbonaceous asteroid that killed the giant dinosaurs and countless other ancient creatures.

Scientists have uncovered the "genetic fingerprint" of the dinosaur-killing Chicxulub impactor, potentially revealing the fateful rock's origins in the outer reaches of our solar system.

The deposits left by the asteroid impact at Chicxulub, Mexico, are similar to other asteroids from the outer solar system.

The asteroid responsible for our last mass extinction 66 million years ago — wiping out the dinosaurs — originated from the far reaches of our solar system, unlike most asteroids that have struck Earth,

Sixty-six million years ago, an enormous asteroid collided with Earth, contributing to a mass extinction event that wiped out all the non-avian dinosaurs. Now, scientists suggest they’ve tracked down the origin of this celestial agent of destruction.

A new study published in the journal Science may have finally pinpointed the origin of the dinosaur-killing asteroid. Based on the evidence, it appears that … The post New study claims dino-killing asteroid originated beyond Jupiter appeared first on BGR.

An asteroid, not a comet, created the Chicxulub crater and caused the extinction of the dinosaurs over 66 million years ago.

We now know where the asteroid that led to the extinction of the dinosaurs and other species came from. A new study confirms it was not a comet and pinpoints its origin. New research sheds light on the origin of the asteroid that,
