It's been over 40 years since the Apollo moon missions ended, but those landmark journeys are still teaching us a thing or two.
Seismic data has recently been recovered from the 1972 Apollo 16 mission detailing over 200 moonquakes—210 to be exact—which had previously trembled undiscovered.
In all, about 13,000 moon-based tremors have so far been identified on Earth's only natural satellite. Quite a few of these tremors were cataloged by humans—-a somewhat laborious process to say the least.

But as any fan of science fiction—or in this case science fact—knows, computers are typically a bit more observant and efficient. Think Terminator-like precision.
Thus, a researcher from the Max Planck Institute developed an algorithm to detect moonquakes that works akin to speech-recognition software.
