In 2021, evidence for a probable impact 3.46 billion-years ago at Pilbara Craton has been found in the form of a 150 kilometres (93 mi) crater created by the impact of a 10 kilometres (6.2 mi) asteroid (named "The Apex Asteroid") into the sea at a depth of 2.5 kilometres (1.6 mi) (near the site of Marble Bar, Western Australia).

Luis Walter Alvarez, left, and his son Walter, right, at the K–T Boundary in Gubbio, Italy, 1981. The Alvarez hypothesis posits that the mass extinction of the non-avian dinosaurs and many other living things during the Cretaceous–Paleogene extinction event was caused by the impact of a large asteroid on the Earth.
Unknown to them, evidence of the crater they were looking for was being presented the same week, and would be largely missed by the scientific community.

Researchers at University New South Wales (UNSW) believe they’ve found evidence that an asteroid impact buried near the town of Deniliquin, Australia, is the world’s largest ever discovered ...
They also uncovered evidence of the asteroid impacts in the form of thousands of tiny droplets of glass, or the compound silica. The droplets form after silica-containing rocks are vaporized by an ...
It has been a long-held belief that it was the impact of an asteroid that ended the age of dinosaurs, but researchers have revealed that the one key element may have played a larger part than ...
This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the impact in advance. As of December 2024, all of the asteroids with predicted impacts were under 5 m (16 ft) in size that were discovered just hours before impact, and burned up in the atmosphere as meteors.
German scientists found evidence that the space rock came from the outer ... “We found that the impact of an asteroid like the one at Chicxulub is a very rare and unique event in geological time ...
