Largest Lunar Explosion In NASA History Caught On Video

NASA has been observing the moon for “lunar meteor showers” — some causing explosions on impact — for eight years. Now, the agency is announcing seeing the largest explosion in all this program’s history.

“It exploded in a flash nearly 10 times as bright as anything we’ve ever seen before,” said Bill Cooke with NASA’s Meteoroid Environment Office of the explosion that took place March 17, according to NASA’s website.

The explosion was so large, in fact, that it could have been seen from Earth with the naked eye.

NASA scientists speculate the meteoroid weighed 40 kg (about 88 pounds) and was less than 0.5 meters (about 1.6 feet) wide. But moving at 56,000 miles per hour, they compare its resulting explosion to the detonation of five tons of TNT.

Here’s a look at video showing just the explosion:
