Scientists are convinced that the best way to find aliens is by throwing a satellite web across the world.
Boffins say that global censor coverage is the best way to discover the truth about extraterrestrials with Jacob Haqq-Misra calling for "a world network of detectors".
The scientist, from the Blue Marble Space Institute of Science in Seattle, said: "If you want to understand a particular set of data you need to know something about the instrument that collected the data.
"What you would need is to set up a network of detectors all around the world. Ideally, you'd have ground-based sensors and you'd have satellite coverage."
The claims follow military chiefs in the United States confirming that unidentified objects had been spotted in the sky in the first public hearing about UFOs for decades.
