"The search for extraterrestrial intelligence (SETI) involves a number of projects. All of them have the objective of finding evidence of extraterrestrial intelligence through radio signals from space. The first of these projects was led in 1960 by Professor Frank Drake, astronomer and now director of SETI Institute. Project Phoenix is the main project of the institute, with an annual budget of $4 million to $5 million. It uses large radio telescopes to receive electromagnetic signals from nearby stars like the sun, that are less than 200 light years away. Besides the SETI Institute, other research institutions working on similar projects include: SERENDIP (Search for Extraterrestrial Radio Emissions from Nearby Developed Intelligent Populations); SETI@Home at University of California, Berkeley; Southern SERENDIP in Australia; Harvard SETI Group; and others."
