THE man in the moon is humming a tune, but thankfully the noise won't drown out sensors on future missions peeking at the lunar interior.

A steady barrage of small meteorite impacts should cause the moon to "ring", but no seismometers sent to the moon to date have been sensitive enough to hear it. So Philippe Lognonné at the Institute of Earth Physics of Paris and colleagues decided to work out how loud the ring is.

The team estimated the meteorite population in the solar neighbourhood, and calculated the likely seismic signals that would be created by a range of meteorite sizes and velocities as they strike the moon.

New Scientist Article

Im sure this is going to kick up a storm with the hollow planet theorists, especially with the Apollo "ringing like a bell" story. None the less i find this a very interesting article, just think the earth and moon are humming now but we cannot here them, in fact the earth is 1000x louder!

I found this bit interesting too...

The first instrument may be a seismometer proposed for Japan's Selene-2 moon mission, which aims to send a lander to the surface, perhaps as early as 2015.

Does this mean we might actually get some new high res pics of the moons surface!?!? It would be nice to see, especially with modern digital camera equipment. Good luck to the Japanese!

The Moon hums because it doesn't know the words.

Thanks for the article and a shot a joke.

Very interesting piece of information, thanks for sharing...

This could certainly be an explanation for the "Apollo Hum"(althought the 'hum' would still need to be propogated through the onboard electronics since sound can not propagate in a vacuum.), none-the-less it is still a nice observation.

For what it's worth it seems to be a very old conspiracy somebody is rehashing

Hollow Moon?

Proof that the "ringing" of the moon is common knowledge in the scientific and NASA communities is presented in communications between Mission Control and the men aboard the Apollo 17 moon mission on December 29, 1972.

"LUNAR MODULE PILOT (LMP): Was there any indication on the seismometers on the impact about the time I saw a light flash on the surface? CAPCOM: Stand by. We'll check on that.
LMP: A UFO perhaps, don't worry about it. It could have been one of the other flashes of light
CAPCOM: Jack, just some words from the back room for you. There may have been an impact at the time you called, but . So it would mask any other impact." (3)

I think it seems they are pretty certain of a hum though, its not just they have an idea. Vibrations from any impact should cause a minute hum imo, it would not require the moon to be hollow either.
