NASA Now Wondering: Are Aliens Actually Planet Hopping? [VIDEO]

Last February, NASA announced that a new Solar System had been discovered not too far away from Earth. Trappist-1 is composed of a star and seven exoplanets that orbit around it—three of which could be suitable for life. Now, a recent study suggests there could be aliens living in the star system jumping from one planet to another.

The study suggests that the planets might be so close to each other that microbes can just jump from one body to another in a pattern called “panspermia.” The theory was presented by Mansavi Lingam and Avi Loeb of Harvard University, who speculate that object collision could send materials into space that later falls into the neighboring planet.

“The rocks are driven into space,” Loeb said in an interview with Gizmodo. “If there is life on one of them, life may be preserved inside these rocks and be transferred to another planet.”

“These planets are similar to islands on the surface of the Earth, and there are studies of the immigration of species from one island to another,” he added. “We used the same model to illustrate that the likelihood is very high for transfer of life.”
