We will have definitive evidence of alien life in 20 years, Nasa chief scientist believes
…and when we do will they differentiate in their world between urban and rural????
The discovery of extra-terrestrial life, probably the most exciting event in human history, may well take place within most of our lifetimes, a high-ranking Nasa scientist has predicted.
“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,” Nasa chief scientist Ellen Stofan said on Tuesday, during a panel discussion focusing on the space agency’s search for habitable environments outside of Earth.
“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.”
Nasa believes such discoveries could happen so soon as they will not take place in deep space but in our own solar system and others in the Milky Way.
Sharing Stofan’s optimism, associate administrator for Nasa’s Science Mission Directorate John Grunsfeld said: “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.”
