Latest Chicxulub crater Stories
The impactor believed to have wiped out the dinosaurs and other life forms on Earth some 65 million years ago has been traced back to a breakup event in the main asteroid belt. The finding provides insights into one of the most important extinction events in Earth's history.
There's growing evidence that the dinosaurs and most their contemporaries were not wiped out by the famed Chicxulub meteor impact, but by multiple meteor impacts, massive volcanism in India, and climate changes.
A new study of melted rock ejected far from the Yucatan's Chicxulub impact crater bolsters the idea that the famed impact was too early to have caused the mass extinction that killed the dinosaurs 65 million years ago.
Scientists have explained how a globe-encircling residue formed in the aftermath of the asteroid impact that triggered the extinction of the dinosaurs. The residue consists of sand-sized droplets of hot liquid that condensed from the vapor cloud produced by an impacting asteroid 65 million years ago.
Scientists working off the Yucatan Peninsula are preparing to use sound waves to search for information about an asteroid that may have wiped out the dinosaurs 65 million years ago. But environmental activists are trying to shut the project down.
How the earth might recover from a mass extinction is as important as what might have caused the catastrophe in the first place. Penn State astrobiologists are looking at species immigration as one way for the Earth to recover its biodiversity.
