Site of asteroid impact changed the history of life

An asteroid, also known as the Chicxulub Impactor, hit Earth some 66 million years ago, causing a crater 180 km wide. The impact of...

Dinosaur-killing asteroid impact cooled Earth’s climate more than previously thought

The Chicxulub asteroid impact that wiped out the dinosaurs likely released far more climate-altering sulfur gas into the atmosphere than originally thought, according to...

Dino-killing asteroid’s impact on bird evolution

Human activities could change the pace of evolution, similar to what occurred 66 million years ago when a giant asteroid wiped out the dinosaurs,...

Dino-killing asteroid could have thrust Earth into two years of darkness

Tremendous amounts of soot, lofted into the air from global wildfires following a massive asteroid strike 66 million years ago, would have plunged Earth...

New study ranks hazardous asteroid effects from least to most destructive

If an asteroid struck Earth, which of its effects -- scorching heat, flying debris, towering tsunamis -- would claim the most lives? A new...

Mechanism underlying size-sorting of rubble on asteroid Itokawa revealed

In 2005, the Hayabusa spacecraft developed by the Japan Aerospace Exploration Agency (JAXA) landed on Itokawa, a small near-Earth asteroid named after the famous...

Earth is bombarded at random

Asteroids don't hit our planet at regular intervals, as was previously thought. Earth scientists have reached this conclusion after analyzing impact craters formed in...

Myth busted: No link between gigantic asteroid break-up, rise in biodiversity

Some 470 million years ago, during the middle part of the geological period known as the Ordovician, an asteroid collision took place somewhere between...

Asteroid impacts could create niches for early life, suggests Chicxulub crater...

Scientists studying the Chicxulub crater have shown how large asteroid impacts deform rocks in a way that may produce habitats for early life. Around 65...

Soot may have killed off the dinosaurs and ammonites

A new hypothesis on the extinction of dinosaurs and ammonites at the end of the Cretaceous Period has been proposed by a research team...

Multiple cosmic impacts 790,000 years ago

Approximately 790,000 years ago, there were multiple cosmic impacts on earth with global consequences. Geoscientists from Heidelberg University reached this conclusion after dating so-called...

Scientists find link between comet, asteroid showers and mass extinctions

Mass extinctions occurring over the past 260 million years were likely caused by comet and asteroid showers, scientists conclude in a new study published...
