Find aliens within 20 years
Nasa scientists are certain that humanity will detect alien life within decades with the aid of more powerful new telescopes. Matt Mountain, director and Webb telescope scientist at the Space Telescope Science Institute in Baltimore says:
What we didn’t know five years ago is that perhaps 10 to 20 percent of stars around us have Earth-size planets in the habitable zone. It’s within our grasp to pull off a discovery that will change the world forever.
