Experts at the National Aeronautics and Space Administration (NASA) believe that they could be able to find alien life in next 10 to 20 years.
Talking to a public panel on Tuesday in Washington, Ellen Stofan, chief scientist for the National Aeronautics and Space Administration, said that she believes “we are going to have strong indications of life beyond Earth in the next decade and definitive evidence in the next 10 to 20 years.”
“We know where to look, we know how to look, and in most cases we have the technology,” Stofan said.
What type of aliens are scientists are expecting to find? Stofan noted that “we are not talking about little green men. We are talking about little microbes.”
At the event, NASA experts talked about recent discoveries related to life in the solar system and beyond.
Jim Green, director of planetary science at NASA, said that a new study found that 50% of Mars’ northern hemisphere once had oceans up to a mile deep. The planet had water for around 1.2 billion years, according to the study.
“We think that long period of time is necessary for life to get more complex,” Stofan said.
Another recent study related to aurora on Jupiter’s moon Ganymede revealed that it has a large liquid ocean beneath its icy crust.
“We now recognize that habitable zones are not just around stars, they can be around giant planets too,” Green added. “We are finding out the solar system is really a soggy place.”
John Grunsfeld, associate administrator at NASA, believes that next generation of scientists and space explorers will be able to find life beyond Earth.
Green said that “the science community is making enormous progress. And I’ve told my team I’m planning to be the director of planetary science when we discover life in the solar system.”
As we reported previously, a new report has found that the National Aeronautics and Space Administration (NASA) could send humans to Mars within next 15-25 years. The space agency’s Mars mission could reach orbit by 2030, and it is possible that a team of astronauts will be walking on the red planet by 2039.
Recently, scientists disclosed a new plan to make contact with aliens.
At the annual meeting of The American Association for the Advancement of Science, scientists proposed an idea of sending messages in the direction of the closest stars to earth in order to contact aliens. Currently, researchers are trying to track radio signals from alien planets.
Seth Shostak, who is director of the Center for SETI Research at the SETI Institute, said that we need to transmit the content of the internet into the outer space. We can transmit large amount of texts, videos, sounds, and pictures. This content could enable aliens learn about our planet.
