Don't worry, we still haven't found any aliens and there will not be any "Mars Attacks" headlines anytime soon. But, Russian Cosmonauts have discovered living organisms attached to the International Space Station, and scientists have no idea how it got there.

This is the first time living organisms have been found on the I.S.S.  The discovery happened on a routine space walk to clean the surface of the space station.

The organisms are a type of sea plankton and how they've stayed alive in outer space is what scientists are scratching their heads over.

The organisms are not native to the Khazakstani ocean where the vessel launched from.  So, scientists theorize that the plankton may have been swept up in air currents into the atmosphere' eventually landing on the space station.

It's not aliens, but it is life in outer space.  Hopefully science can soon explain the discovery and we won't have to worry about the "Attack of the Sea Plankton."
