Chicxulub Impactor

What are some of the largest extraterrestrial impacts to effect Earth? Learn what we've seen in history, and what is important to know today.

Learn how asteroid strikes may have only altered Earth's climate for about 25 years.

The so-called Chicxulub impactor was a carbonaceous-type asteroid that had formed beyond the orbit of Jupiter, according to a new paper published in the journal Science.

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...

An intense debate surrounding the cosmic rock that killed the dinosaurs has stirred scientists for decades, but a new study has revealed some important—and far-out—data about the impactor's origin story.

Large asteroids and meteors, such as the Chicxulub Impactor, may change the scope of the planet. But which asteroids should we be looking out for?

A Martian megatsunami may have been caused by an asteroid collision similar to the Chicxulub impact—which contributed to the mass extinction of all non-avian dinosaurs on Earth 66 million years ago—in a shallow ocean region, according to a study published in Scientific Reports.

A newly discovered impact crater below the seafloor suggests that more than one asteroid may have hit Earth during the time when dinosaurs went extinct. Evidence of an asteroid impact crater beneath the North Atlantic Ocean has been discovered by scientists. It could force researchers to rethink

The number of dinosaurs may have been stable before the asteroid impact, despite evidence that species were getting less diverse

The insects grew fungi crops millions of years before humans even existed.

The cataclysmic asteroid left deposits similar to those made by other asteroids from the outer solar system.

A recently published study has shed more light on the cataclysm that ended the dinosaur era. Data from the research can also help scientists learn more about...

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.

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.

Evidence suggests a celestial body exploded in Earth's atmosphere 12,800 years ago. The comet burst may have cooled the climate for around 1,200 years. The post Did a comet burst crash Earth's climate 12,800 years ago? first appeared on EarthSky.

Are dinosaurs real? Most people don't have to travel too far to answer that question in the affirmative with some kind of exhibit displaying dinosaur fossils. Or simply look at any bird you can see outside your home.

A pair of researchers, Guillaume Guinot and Fabien Condamine, both with Université de Montpellier, in France, has looked at the impact of the Cretaceous–Paleogene (K-Pg) extinction event on elasmobranch species to learn more about survival of marine creatures during extinction events. In their study, published in the journal Science, the marine biologists collected and analyzed data for thousands of fossil species…
