Explosion on moon visible from earth

I do not know whether the hobbying astronomers watched this or not, but NASA did notice a bright explosion on moon which was visible from the earth.

Explosion on the moon, reported by NASA May 17, was caused by a meteor hitting the surface and was visible on earth to the naked eye

The explosion was caused by a meteoroid that struck the moon surface recently, says NASA on Friday. The impact caused an explosion that was visible on Earth without the aid of a telescope. But don't be alarmed if you didn't see it; it only lasted about a second.

"It exploded in a flash nearly 10 times as bright as anything we've ever seen before," said Bill Cooke, of NASA's Meteoroid Environment Office.

NASA's lunar monitoring program has detected hundreds of meteoroid impacts. The brightest, detected on March 17, 2013, in Mare Imbrium, is marked by the red square

NASA says the meteoroid was about 40 kilograms and less than a meter wide, and it hit the moon's surface at 56,000 mph. It glowed like a 4th magnitude star, NASA says, thanks to an explosion equivalent to 5 tons of TNT.

However there is one question which may or may not have come to your mind. But if you're wondering how there can be an explosion on the moon, without oxygen, NASA has the answer for you. It says the flash of light comes not from any type of combustion - as we typically think of explosions - but rather by the glowing molten rock at the impact site.

So this is the answer which may add to your knowledge if you are a hobbying astronomer. So keep watch moon more  - you may find another explosion too if you are lucky.
