Here’s a cheery thought to send you into the weekend: New research suggests that the greatest danger posed by an incoming asteroid is not from the cataclysmic impact of it striking the Earth—but from the enormous shockwave it produces when it enters the atmosphere.
In celebration of World Asteroid Day this week, scientists came out of the woodwork to explain to all the different ways we can prevent an asteroid from causing an Armageddon-level apocalypse.
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.
