Search for Extra Terrestrial Intelligence

Search for Extra Terrestrial Intelligence (SETI) was a 20th century Earth effort to explore, understand and explain the origin, nature and prevalence of extraterrestrial life – most notably alien intelligence – in the universe. 
The SETI greeting was displayed on a plaque on the hull of such NASA probes as Voyager 6 and Pioneer 10. (; )
In 1996, a young researcher, Rain Robinson, detected the and transmitted the standard SETI greeting. ()
