Measuring 250 miles (400 km) wide, the now-buried crater in Australia was ground zero for a cataclysmic impact that occurred some 300 million years ago. But is it really the largest on Earth?
New research suggests the Earth was pummelled by four gigantic asteroids measuring at least 600 miles across in its early days — impacts that would have rebooted the surface, boiled off the oceans, and extinguished any fledgling life. Here's what we now know about the Late Bombardment Era and its affect on our…
Around 3.26 billion years ago — long before the dinosaurs — a massive asteroid measuring nearly 36 miles (58 km) across smashed into the Earth. Geologists have now reconstructed this cataclysmic event, and it was far, far bigger than we thought. Here's how things went down on that fateful day.
Mark August 26th, 2032 on your calendar, folks. Ukrainian astronomers have just detected a 1,350-foot-wide (410 meter) minor planet that’s headed our way. The impact risk is minimal, but it’s now the most serious near-term celestial threat to face our planet.
