"It would change the way everybody thinks about his or her place in the cosmos, what I like to call our place in space. it's reasonable that there could be living things, and as they say if we were to discover life on another world like Europa, it would change this world," he said. NASA is also making plans to send an unmanned probe to one of Jupiter's moons Europa, where oceans of water are believed to lie below its surface, theoretically capable of supporting life.īill Nye from the US Planetary Society told the BBC he believed that mission would be well worth the $2 billion price tag. "So I would say probably you're talking about somewhere within the next 10, maybe 20 years we'll start finding life elsewhere in the universe." Loading.īut evidence of alien life might also be relatively close to home. Life on planets around other stars also might be hidden in a subsurface ocean encased in ice, invisible even to our most powerful space telescopes. "And now we're starting to find them in that region, the habitable zone where you might actually find life where there's likely to be liquid water and so on. On an otherworldly landscape in Mono Lake, California, scientists have tested a new method for potentially detecting chemical signatures of life on another planet. "Twenty-five years ago we didn't even know any planets outside the solar system existed, and now we're up to a couple of thousand of them," he told the BBC. The finding makes Enceladus the most promising place, the lowest-hanging fruit, in our solar system to search for extraterrestrial life, Carolyn Porco, a planetary scientist who was not. It is an agenda exciting stargazers the world over, including Michael Merrifield, professor of astronomy at Britain's University of Nottingham. In June 2018, NASA announced the detection of seasonal variation of. Missions to Europa could find signs of life The possibility of life on Mars is a subject of interest in astrobiology due to the planets. ![]() Their message to the world: "Our understanding of the universe around us is on the verge of being dramatically changed forever."ĭr Mountain is from the Space Telescope Science Institute which is collaborating with NASA to launch the most powerful device yet to explore the universe - the James Webb Space Telescope, due to be launched in 2018.īut NASA believes that within the next two decades it will have the capability to peer into deep space for signatures of life. "We believe we're very, very close in terms of technology and science and actually finding the other Earth and our chance to find signs of life on another world," Dr Seager said. They say scientific advances in rocket technology and space telescopes will soon make it possible to scan the heavens for the tell-tale signs of life on a planet not unlike our own, their so-called Earth 2.0. As NASA explores the solar system, our understanding of life on Earth and the potential for life on other worlds has changed alongside the many discoveries. NASA scientists predict they are within 20 years of finding the evidence proving we are not alone in the universe.ĭr Sara Seager and Matt Mountain were two of the distinguished scientists, former astronauts and engineers brought together by NASA.
