Mysterious bacteria on Space Station hull...
FIRST ALIEN CONTACT?
Russian cosmonauts find mysterious bacteria on the hull of the International Space Station that may NOT be from Earth.
Microorganisms from Earth have been found on the station's skin before but they have got there thanks to the ionosphere lift phenomenon, where substances from Earth rise into the atmosphere.
Shkaplerov said: "Bacteria that had not been there during the launch of the ISS module were found on the swabs.
"So they have flew from somewhere in space and settled on the outside hull."
He added that the samples are being probed by scientists and seem to be safe.
Incredibly, bacteria found on the ISS can survive in a vacuum and temperatures ranging from -150C to 150C.
Last month Sky reported that bacterial cells treated with a common antibiotic were spotted changing shape to survive while aboard the ISS.
The defence mechanism could pose a serious problem when it comes to treating astronauts with infections.
The "clever shape-shifting" is believed to help the bacteria survive.
Dr Luis Zea, the study's lead author, said: "We knew bacteria behave differently in space and that it takes higher concentrations of antibiotics to kill them."
