Nasa scientists have witnessed a rare explosion on the Moon, caused by a "meteoroid" slamming into it.
The blast was equal in energy to about 70kg of TNT and was seen near the edge of Mare Imbrium (the Sea of Rains).
The object that hit the Moon was probably part of a shower of "taurids" which peppered Earth in late October and early November.
Understanding lunar impacts could help protect astronauts when Nasa sends humans back to the Moon.

LOL
The kinetic energy of the incoming meteoroid has to go someplace. Some of it's going to go into the ejecta, much of it's going to go into a sound wave that propagates through the moon, but some of it's going to go into heat. The heat is enough briefly to ionize some of the material. As the ionized atoms recombine with electrons, they give off light.
The hot matter that is left over will also, for a time, give off light through incandescence, just like a light bulb filament. Hot things just radiate light.
The energy of the the collision is enough to heat the material to incandescence. It's not a fire, any more than the filament in an electric light bulb is "burning". It gives off light because it's HOT.
Hehehe...
Duck?

TROP?
Beat ya...

Man they are so right about those meteoroids!
I had a Torid relationship with a redhead once, she was
Eexplosive!!!
Thanks for all of the info about the meteor flash. There are some very educated freepers out there.
I learn something new every day on FR.
alas:
