There are several ways alien life could travel across space, scientists say.
Cosmonaut Anton Shkaplerov lit a wildfire recently when he announced his team had found alien bacteria clinging to the outside of the International Space Station (ISS). It took place during a spacewalk several years ago. Those samples were returned to Earth and have been analyzed recently by Roscosmos—the Russian space agency. He claims Roscosmos scientists conclude the bacteria isn’t from Earth. One thing is for sure, there’s living bacteria clinging to the outside of the ISS! Whether it’s extraterrestrial or not is another matter.
