NASA: We’ll find alien life in 20 to 30 years

There will be “strong indications” of alien life within a decade and “definite evidence” of it within 20 to 30 years, NASA’s chief scientist has said. “We know where to look. We know how to look,” Ellen Stofan said during a panel discussion on NASA’s search for alien life and habitable worlds. “In most cases, we have the technology, and we’re on a path to implementing it.”

“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,” Grunsfeld said  Jeffery Newmark, NASA’s interim director of heliophysics, added: “It’s definitely not an if, it’s a when.”

Scientists have been searching for extraterrestrial life for years. One way was by searching for alien air pollution.

And recent discoveries suggest that several nearby planets — and their moons — could support some form of life. For example, scientists said they thought there was a warm ocean on Saturn’s moon Enceladus.  NASA scientists confirmed that Jupiter’s moon Ganymede has a salty ocean below its surface. Scientists believe that the presence of water is one possible sign of life.
