Dust from a cataclysmic asteroid collision that occurred beyond the orbit of Mars some 468 million years ago may have helped trigger an ice age and an explosion of biodiversity in life on Earth.

This finding, published on Wednesday in Science Advances, is a mind-boggling example of how events in outer space can exert a major influence on the climate and evolutionary history of our planet. Led by Birger Schmitz, a professor of geology at Lund University in Sweden, the study’s authors demonstrate how asteroid dust can cause global climate cooling, and even suggest that this type of debris could be one potential solution to human-driven climate change.
