Explosions on the Moon

Meteor showers are great fun. The streaks and flashes create a special type of astronomical fireworks. But there are some people out there who enjoy meteor showers in a different way. They don't watch the meteors. Instead, they watch the moon. There are fireworks there, too, in the form of explosions — equivalent to about 100 pounds of TNT — when meteors hit the lunar surface.On August 9th, during the Perseid meteor shower, a couple of amateur astronomers fixed their cameras on the Moon and watched meteoroids slam into the lunar surface. Silent explosions produced flashes of light visible a quarter of a million miles away on Earth. It was a good night for "lunar Perseids."
