German scientists think they've cracked the case on the origins of the giant asteroid that all but wiped out the dinosaurs 66 million years ago. Now, a team of geoscientists from the University of ...

66 million years ago, a large asteroid crashed into Earth near Mexico's Yucatán Peninsula, sparking a frigid global winter that led to the mass extinction of dinosaurs who had reigned over the planet ...

Off the coast of Mexico, the Chicxulub crater is all that remains of a defining moment in Earth's history. The hole spans 93 miles wide and bores 12 miles deep into the Earth. It was left by an ...

For decades, the scientific community has largely agreed that amassive asteroid impact 66 million years ago led to the mass extinction of the dinosaurs, triggering a global ‘impact winter.’ The theory ...

Impact craters often have asymmetric shapes, which have been used to infer the direction and angle of impact. But pre-existing structural or topographic heterogeneities also play an important role in ...

Harvard astrophysicists proposed a new model showing that the Chicxulub impactor — the celestial body responsible for the mass extinction of the dinosaurs — could have been of cometary, rather than ...
