An asteroid bombardment impacted both the Moon and Earth roughly 800 million years ago, new research suggests. By dating the craters on the Moon, researchers were able to estimate when the Earth ...

Over the course of Earth's ancient history, our planet has been blitzed with a variety of foreign objects, some of which may have triggered major events shaping this place we now call home.
