Two Asteroids Collided in Deep Space, Sparking an Ancient Ice Age

This artist's concept captures the catastrophic collision that destroyed the parent body, which was bigger than any known asteroid break-up in the past 3 billion years. (Credit: Don Davis/Southwest Research Institute.) A giant collision between two asteroids may have triggered a global ice age that hit Earth some 466 million years ago. The cosmic crash which took place between Mars and Jupiter and destroyed an asteroid some 93 miles (150 km) wide created a thick plume of dust that sprea
