Latest Impact events Stories
An ancient meteorite and high-energy X-rays have helped scientists conclude a half century of effort to find, identify and characterize a mineral that makes up 38 percent of the Earth.
After the asteroid impact at the end of the Cretaceous period that triggered the dinosaurs' extinction and ushered in the Paleocene, leaf-mining insects in the western United States completely disappeared.
Twenty years ago, human and robotic eyes observed the first recorded impact between cosmic bodies in the solar system, as fragments of comet Shoemaker-Levy 9 slammed into the atmosphere of Jupiter.
The Moon was most likely formed by a collision between the Earth and a planet-sized object that took place roughly 4.5 billion years ago, a team of German scientists report in research published Friday by the journal Science.
Earth was irrevocably changed when the dinosaurs were wiped out about 65 million years ago by a massive asteroid, but a much bigger asteroid that struck the Earth nearly 3.3 billion years ago is thought to have shaped parts of Africa.
A research team from MIT has determined that the end-Permian extinction took place over 60,000 years — give or take 48,000 years. From a geologic perspective, that's nearly instantaneous.
Divers searching Lake Chebarkul in Russia have pulled from the lakebed a massive chunk of the Chelyabinsk meteorite that exploded over the Ural Mountains region earlier this year.
A new study examines how a group of ancient mammalian relatives coped with a mass extinction event in the prehistoric past as a way to glimpse into the potential future.
A Russian scientist has reportedly found meteorite or asteroid fragments potentially linked to a mysterious explosion that took place over Siberia more than 100 years ago.
Approximately 252 million years ago, during the world’s largest mass extinction event, nine out of ten species vanished from the planet. Scientists now believe this may have made space for dinosaurs' earliest forerunners.
Comet Shoemaker-Levy 9 -- Comet Shoemaker-Levy 9 is so-named because it was the ninth short-period comet discovered by Carolyn and Eugene Shoemaker and David Levy. It was first detected in a photograph taken on the night of March 24, 1993 with the 0.4-meter Schmidt telescope at the Mount Palomar observatory in California, and subsequently observed by many other astronomers. The comet was extremely unusual because it was in fragments, evidently due to a close encounter with the planet...
