NASA: We'll find alien life in 10 to 20 years

“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, chief scientist for NASA, said at a public panel Tuesday in Washington.

“We know where to look, we know how to look, and in most cases we have the technology,” she said.

Jeffery Newmark, interim director of heliophysics at the agency put it this way: “It’s definitely not an if, it’s a when.” 

However, if visions of alien invasions are dancing in your head, you can let those go.
