A six-mile-long asteroid, which struck Earth 66 million years ago, wiped out the dinosaurs and more than half of all life on Earth.The impact left a 124-mile-wide crater underneath the Gulf of ...
The most infamous asteroid impact occurred 66 million years ago, when a six-mile-wide space rock triggered a global winter, wiping out the dinosaurs and 75 percent of all species. By contrast ...
It has been a long-held belief that it was the impact of an asteroid that ended the age of dinosaurs, but researchers have revealed that the one key element may have played a larger part than ...
Artist's impression of the asteroid slamming into tropical, shallow seas of the sulfur-rich Yucatán Peninsula in what is today Southeast Mexico. [13] The aftermath of the asteroid collision, which occurred approximately 66 million years ago, is believed to have caused the mass extinction of non-avian dinosaurs and many other species on Earth.

The asteroid that slammed into Earth 66 million years ago and led to the extinction of dinosaurs was estimated to be about 6.2 miles (10 kilometers) in diameter and marked the last known large ...
A study of 29 fossil sites in Catalan Pyrenees of Europe in 2010 supports the view that dinosaurs there had great diversity until the asteroid impact, with more than 100 living species. [135] More recent research indicates that this figure is obscured by taphonomic biases and the sparsity of the continental fossil record.
The asteroid was discovered three hours before impact by David Rankin at Mount Lemmon Observatory, during routine observations for the Mount Lemmon Survey. [2] The first image was taken at 04:53 UT when the asteroid was 0.000859 AU (128.5 thousand km; 79.8 thousand mi; 0.334 LD) from Earth. [11]
The asteroid that killed most dinosaurs 66 million years ago left behind traces of its own origin. Researchers think they know where the Chicxulub impactor came from based on levels of ruthenium.
