Explosion on the Moon

For the past 8 years NASA have been monitoring the Moon for explosions caused by large objects hitting its surface. Scientists have been surprised to discover that the Moon is receiving a lot more battering that previously thought. They are registering hundreds of explosions on the lunar surface every year.

They have just seen the largest explosion since the program start.

On 17th of March an object weighting 40 kg and measuring 30-40 cm across hit the Moon's surface. It was travelling at 56'000 miles per hour speed.

Unlike the Earth, the Moon does not have air atmosphere that could protect it from such impacts. A metheorite of similar size, weight and speed would simply have burned and exploded in the upper levels of the Earths atmosphere. But the Moon does not have such protection and therefore is exposed to the attacks from the space.
