Scientists have taken a close look at our activity within the solar system to determine where to look for signals from intelligent alien life. The findings apply if those extraterrestrials explore their own cosmic backyards in a way similar to us.
A team from NASA's Jet Propulsion Laboratory (JPL) and Penn State University looked at when and where human transmissions would be most detectable by intelligent life outside the solar system. This helped to build patterns that could be employed by SETI in its hunt for signs of intelligent life or "technosignatures" beyond the solar system.
