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. [13] The impact spewed hundreds of billions of tons of sulfur into the atmosphere, producing a worldwide blackout and freezing temperatures which ...
Researchers say they are surprised to discover that two massive asteroids that slammed into the Earth 35 million years ago caused no real climate impact. After the asteroid that wiped out the ...
An animation modelling the impact, and subsequent crater formation of the Chicxulub impact (University of Arizona, Space Imagery Center) The prehistoric Chicxulub impact, 66 million years ago, believed to be the cause of the Cretaceous–Paleogene extinction event, was caused by an asteroid estimated to be about 10 kilometres (6.2 mi) wide.

This list of impact structures (including impact craters) on Earth contains the majority of the 194+ confirmed impact structure given in the Earth Impact Database as of 2024. [1] Alphabetical lists for different continents can be found under Impact structures by continent below.
The 15-kilometer-wide meteorite hit land to make the 150-kilometer-wide Chicxulub crater and in the process, wiped out most dinosaurs, mammals, and marine and avian reptiles (although volcanic ...
