There's been a lot of buzz about the moon lately, and for good reason.

The 50th anniversary of Apollo 11, the first spaceflight to land people on the moon, is coming up in July.

While that's pretty common knowledge, you might not be aware of what that mission's seismic experiment found: moonquakes.

NASA's Apollo missions had seismometers at four locations that recorded moonquakes between 1969 and 1977, but the epicenters couldn't be pinpointed.

Researchers have now developed an algorithm that gives much more accurate estimates of the epicenter locations.

Scientists discovered young thrust faults on the surface of the moon that they attributed to "recent" tectonic activity, but it couldn't be determined how recent, the study says.
