Russian astronauts, or cosmonauts, have discovered living organisms clinging to the exterior of their International Space Station.
The microscopic creatures were discovered during a space walk to clean the surface of the vessel, and they’ve reportedly been identified as a type of sea plankton. But scientists have no idea how they got there.
"Results of the experiment are absolutely unique. This should be studied further," Russian ISS Orbital Mission Chief Vladimir Solovyev told ITAR-TASS.
Currently, the Russian space agency is unable to explain how sea plankton - you know, from Earth's oceans - ended up on a vessel in outer space. Their only explanation is that atmospheric currents may be lifting the particles from the ocean all the way to the station - about 205 miles up in the sky.
