About 466 Mya, a major impact event took place between the orbits of Mars and Jupiter. Space dust spread all across the Solar System, and some of it was found near Saint-Petersburg, Russia, and in the south of Sweden.

Earliest Jurassic Corals Discovered

Five times in Earth's history mass extinction events have wiped out up to 90 percent of global life.

The detectability of planetesimal impacts on imaged exoplanets can be measured using Jupiter during the 1994 comet Shoemaker-Levy 9 events as a proxy.

A new study shown that meteorite impacts on ancient oceans may have created nucleobases and amino acids.

Rock soil droplets formed by heating most likely came from Stone Age house fires and not from a disastrous cosmic impact 12,900 years ago, according to new research from the University of California, Davis.

The extinction of the dinosaurs 66 million years ago is thought to have paved the way for mammals to dominate, but a new study shows that many mammals died off alongside the dinosaurs.

The cratering record on the Earth and Moon shows that our planet has been exposed to high velocity impacts for much or all of its existence. Some of these craters were produced by the impact of long period comets (LPCs).

A new study from Western University explores the possibility that Earth's earliest life forms may have been cultivated by a meteorite impact event.

In 1980, Alvarez and colleagues proposed that, in the transition from the Cretaceous to Paleogene, a large impactor collided with Earth being the cause of the mass extinction occurred at the limit K/Pg.

It is now understood that the accretion of terrestrial planets naturally involves giant collisions, the moon-forming impact being a well known example.
