Intelligent life may exist somewhere else in the universe other than Earth, NASA Administrator Bill Nelson said in an interview Tuesday, and NASA is actively looking for signs.

“If you have a universe that is 13.5 billion years old — it is so big — is there another chance for another Sun and another planet that has an atmosphere like ours? I would say yes, so I think we’re going to get some indication that there’s intelligent life out there,” said Nelson during an interview Tuesday.

In a report on unidentified flying objects released June 25, the U.S. government couldn’t clarify 143 of the 144 cases of UFOs revealed by military planes from 2004 to 2021, as per the Office of the Director of National Intelligence.

Nelson told CNBC’s “The News with Shepard Smith” that NASA has been engaged with looking for intelligent life for years, and noticed that the organization is searching for life on the planets in our solar system and somewhere else in the cosmos to decide different Suns that have planets with a habitable atmosphere.

The previous Florida Senator added that part of the inquiry incorporates studying Mars. NASA’s experimental helicopter Ingenuity made its ninth flight on Mars on Monday. Ingenuity flew for almost 3 minutes, going as quick as 5 meters (more than 16 feet) each second, as indicated by a tweet from NASA’s Jet Propulsion Laboratory in California.

“This particular time, it’s scouting a very sandy region in order to determine should the rover go there and possibly get stuck in the sand, so Ingenuity is just doing amazing things,” Nelson said.

NASA depicted Ingenuity’s most recent trip as “the most nerve-wracking flight since Flight 1.”
