But seriously, we all know martians live UNDERGROUND… 

For the first time, a NASA spacecraft has directly observed “alien” particles that came from beyond our solar system, astronomers announced today.

The discovery not only gives us a glimpse of what exists in the so-called interstellar medium—the matter between stars—but also offers clues to the anatomy of our local galactic neighborhood.

Orbiting Earth some 200,000 miles (322,000 kilometers) away, the Interstellar Boundary Explorer (IBEX) spacecraft was able to snag samples of hydrogen, oxygen, and neon that came from interstellar space.
