Our planet is marked by scars from its tumultuous history, with craters serving as direct evidence of Earth’s violent encounters with celestial bodies. These natural formations have both fascinated ...

Crater Lake is one of Oregon's most mystical lakes, and adding to that mystique is the fact it is the deepest in the U.S. and one of the deepest in the world. The national park is a highly sought ...

This impact feature, called Popigai, is the fourth-biggest impact crater known on Earth, and has remained remarkably uneroded. The second space rock, which was about 3 miles (5 km) wide ...

The rocks, both several miles wide, hit Earth about 25,000 years apart, leaving the 60-mile (100km) Popigai crater in Siberia, Russia, and the 25-55 mile (40-85km) crater in the Chesapeake Bay, in the ...

One created the 60-mile-wide Popigai crater in Siberia, Russia, and the other created the 25-mile-to-55-mile-wide crater in the Chesapeake Bay in the U.S. These craters are the fourth and fifth ...

One hit the region that is now Chesapeake Bay in the United States, creating a crater 25 to 55 miles (40 to 85 kilometers) in diameter. The other impacted Siberia, forming the 60-mile-wide (100 ...
