SETI, of course, is the Search for Extraterrestrial Intelligence that has been taking place throughout various countries and nations on earth for quite some time. The way the site works is that there are a number of telescopes that are pointed in outer space and are picking up radio wave frequencies from what scientists have denoted as likely targets for extraterrestrial existence. These stars have been determined to be likely to providing conditions for life based upon the fact that they have exoplanets from the Kepler field. Furthermore, the site works by a consensus method, in which people are responsible for reporting any radio wave activity that appears as though it has been manipulated by some form of extraterrestrial origin. If enough people are able to witness data from radio frequency interference that is indicative of some form of extraterrestrial intelligence, scientists will know that they should focus on that particular region of space.

This array of telescopes is more effective than a single telescope in that the myriad telescopes provide a wider range of opportunities for detecting radio waves that may have been influenced by extraterrestrials. These telescopes, of course, inform both scientists and participants from the world wide web community of where exactly radio signals are coming from. The telescopes, however, only analyze a radio wave for no more than say 90 seconds before attempting to locate a different point in space, which is why they rely on human observers to denote any activity that looks like it could have come from an extraterrestrial intelligence form. The site is fairly straight forward and relatively easy for people to get involved with, and to actively partake in the scientific search for life outside of earth.
