In Greek mythology, the many-eyed guardian god Argus scrutinized every direction simultaneously. When Argus was dead, his eyes were put on to the peacock's tail. In the search for extraterrestrial intelligence, the SETI League's Project Argus will be similarly all-seeing, constantly surveying the entire sky at radio frequencies. But Project Argus is a confederation of amateurs. In a word, coverage.
Professional telescopes are sensitive to very weak signals.
Such SETI searches also have to compete with professional astronomy projects, and can observe for only a few weeks each year. Huge numbers of amateur astronomers and ham radio enthusiasts around the world have the interest and skills which will make Project Argus a reality. Project Argus will be fully operational within the next few years, constantly searching the radio frequencies known as ' The Waterhole ' across the whole sky for any artificial signals of non-terrestrial origin which might arrive at our planet.
