About 2 billion years ago, an impactor hurtled toward Earth, crashing into the planet in an area near present-day Johannesburg, South Africa. The impactor—most likely an asteroid—formed what is today ...

Impact craters and their broader structures can be visible in a geologic map, like a bullseye. But what geophysical traces remain at the structure’s outermost edges?

In recent research published by myself and my colleague Tony Yeates in the journal Tectonophysics, we investigate what we believe—based on many years of experience in asteroid impact research—is the ...

Researchers developed a more accurate simulation of the impact that formed Earth's largest crater -- Vredefort crater -- nearly two billion years ago. They found the impactor (most likely an asteroid) ...
