Alien hunters should search for artifacts on the moon, study suggests

The famous equation used to search for alien civilizations has now inspired a new formula to hunt for alien artifacts within our solar system.

The quest for these alien artifacts could start with the moon and other cosmic bodies near Earth, a new study finds.

The Drake Equation is used to estimate the number of civilizations in the Milky Way one can detect via their broadcast signals — or, more simply put, the odds of finding intelligent life in our galaxy. First proposed by radio astronomer Frank Drake in 1961, the equation calculates the number of communicating civilizations by analyzing several variables, such as the rate of formation of stars suitable for the development of intelligent life and the number of planets, per stellar system, with an environment suitable for life.
