NASA Admin Bill Nelson believes there are trillion Earth-like planets out there

This incredible number suggests that the possibility of alien life is much higher than we might have thought

NASA administrator Bill Nelson has made a bold statement that sparks curiosity and wonder by saying that there could be at least a trillion “Earth-like” planets in the universe. This incredible number suggests that the possibility of alien life is much higher than we might have thought.

Nelson made this statement while talking about NASA’s plans. The space agency is preparing to send astronauts back to the moon. “Four astronauts are set to orbit the moon next year,” Nelson said. But this mission is not just about returning to the moon. “We don’t need to go back to the moon just for the moon. We’re going back to learn new things. For us to go to Mars and beyond,” he explained.

At the same time, NASA’s Perseverance Rover is busy exploring Mars, specifically the Jezero Crater, which scientists think was once a lake filled with rivers. This area could have supported life in the past. Nelson talked about the rover’s tasks: “It’s getting samples and it’s drilling with this drill, creating these core samples about the size of a cigar and sealing them up in these titanium tubes.”

These samples are crucial for understanding Mars’ history. “We’re trying to figure out right now how we’re going to go back and get them and bring them back to Earth so that we got an idea of whether or not there was life there,” Nelson stated. NASA plans to bring these samples back in the 2030s with help from various companies.

NASA’s search for alien life goes beyond Mars. The agency, working with Firebird Diagnostics, is exploring other signs of life in the universe. “NASA’s mission is to go out, among other things, and discover whether or not we are alone,” expressed Firebird Diagnostics Founder Steven Benner. His company is helping NASA understand different forms of DNA that might exist in alien life.

Benner asks an intriguing question, “It’s a big question as to how molecular biology could be done if it was done by an organism that does not share a common ancestor, a common origin, with you and me.” This research could change our understanding of biology and life.

When asked about extraterrestrial life, Nelson shared his thoughts. “If you ask me directly, do I think that there are aliens here on Earth? I don’t think so. I don’t know. And I don’t think the US government is hiding anything from anybody. But if you ask me, ‘Do I think there’s life out there in the cosmos?'”

NASA’s ongoing exploration and research bring us closer to answering the age-old question of whether we are alone in the universe. Each mission and discovery offer new clues and keep hope alive that we might find signs of life beyond Earth.
