NASA scientists have said finding habitable worlds in the universe is a possibility in the next 20 years. During a panel discussion at NASA’s headquarters in Washington, D.C., on Monday, several of the space agency’s experts said based on advances in space telescope technology, finding alien life may become a reality.
“Many scientists believe we are not alone in the universe,” NASA says on its website. “It’s probable, they say, that life could have arisen on at least some of the billions of planets thought to exist in our galaxy alone – just as it did here on planet Earth. This basic question about our place in the Universe is one that may be answered by scientific investigations.”
Here’s what a few experts had to say about the topic during the discussion and on NASA’s website:
“I think in the next 20 years we will find out we are not alone in the universe.” – NASA astronomer Kevin Hand
“It’s highly improbable in the limitless vastness of the universe that we humans stand alone.” – NASA Administrator Charles Bolden
“Sometime in the near future, people will be able to point to a star and say, ‘that star has a planet like Earth.’ Astronomers think it is very likely that every single star in our Milky Way galaxy has at least one planet.” Sara Seager, professor of planetary science and physics at the Massachusetts Institute of Technology
