A new study has found that there could be as many as a quintillion alien spacecraft lurking in our solar system. The study, conducted by a team of astronomers from Penn State University, looked at the Drake Equation, which is used to estimate the number of intelligent civilizations in the Milky Way galaxy. The researchers found that there could be up to a quintillion intelligent civilizations in our galaxy alone, and each of them could have up to a trillion spacecraft. This means that there could be as many as a sextillion (10^21) alien spacecraft flying around the universe.
