<p>Humans will be able to discover intelligent extraterrestrial life within the next 25 years by detecting alien-produced electromagnetic signals in space, a US scientist has claimed.<br /><br /></p>.<p>By 2040 or so, astronomers will have scanned enough star systems to detect alien-produced electromagnetic signals, according to Seth Shostak of the SETI (Search for Extraterrestrial Intelligence) Institute in Mountain View, California.<br /><br />"I think we'll find ET within two dozen years using these sorts of experiments," Shostak said during a discussion at the 2014 NASA Innovative Advanced Concepts symposium at Stanford University last week.<br /><br />"Instead of looking at a few thousand star systems, which is the tally so far, we will have looked at maybe a million star systems 24 years from now. A million might be the right number to find something," Shostak said.<br /><br />Part of Shostak's prediction is based on progress made by NASA's planet-hunting Kepler space telescope, which has turned up evidence that the Milky Way galaxy is packed with worlds capable of supporting life as we know it, 'SPACE.com' reported.<br /><br />Shostak believes that that one in five stars has at least one planet where life might spring up.<br /><br />"That's a fantastically large percentage. That means in our galaxy, there's on the order of tens of billions of Earth-like worlds," he said.<br /><br />At least some of these worlds host intelligent aliens - beings that have developed the capability to send electromagnetic signals out into the cosmos, as human civilisation does every second of every day, Shostak said.</p>
