Here's the full quote, as delivered by NASA Chief scientist Ellen Stofan at Tuesday's panel discussion on the Agency's search for habitable worlds and alien life:
"I think we're going to have strong indications of life beyond Earth within a decade, and I think we're going to have definitive evidence within 20 to 30 years.

We know where to look. We know how to look," Stofan added. "In most cases we have the technology, and we're on a path to implementing it. And so I think we're definitely on the road."

Former astronaut John Grunsfeld, associate administrator for NASA's Science Mission Directorate, echoed Stofan's assessment. "I think we're one generation away in our solar system, whether it's on an icy moon or on Mars, and one generation [away] on a planet around a nearby star."

Maybe it's time to start placing bets. Personally, my money's on Europa – but each of the following "ocean worlds" listed in this infographic from NASA a solid candidate:
