Alien life is likely to exist somewhere in the universe, the head of NASA has revealed
Bill Nelson, the former space shuttle astronaut and US senator, believes that the universe is too big not to have any forms of extraterrestrial life.
Asked if he believed in aliens at the Financial Times Investing In Space Conference, Nelson said: "The short answer is yes.
"We know that we have in our galaxy, millions, if not billions of suns, and we know that in addition to our galaxy there are millions, if not billions, of galaxies with millions or billions of suns.
"Now, is there a possibility in a universe that big that conditions like Earth have been created? Of course, there is that possibility."
Nelson claims that the James Webb telescope - which was launched last December - could help detect worlds where other life forms can thrive.
He said: "With the telescope, we're going to be able to have such precision to look at a planet and determine the chemical composition of its atmosphere so we can determine if it has a possibility of a habitable atmosphere."
