NASA is certain: We’re not alone in this universe. Speaking at a public panel on Tuesday in Washington D.C., NASA scientists discussed the likelihood of finding organic life in our solar system. Given the surprising number of oceans residing throughout our celestial home, they say "it's definitely not an if, it's a when." "I believe we are going to have strong indications of life beyond Earth in the next decade and definitive evidence in the next 10 to 20 years," Ellen Stofan, NASA's Chief Scientist, said at the panel. Of course, the space agency isn’t talking about deadly xenomorphs or intelligent beings that can take on the personas of hot teenagers. Most likely, any life that NASA finds within our solar system will be simple microbes, the essential building blocks for more complicated creatures yet to come. More via Popular Science.
