SETI

At the core of our explorations is the quest to know if life exists beyond Earth. The Planetary Society is a leader in the search for life on other worlds, whether intelligent or microbial. Our active projects: SETI Optical Telescope - Looking for laser signals beamed across the vastness of space. SETI Radio Searches - Huge radio dishes sift through nature's random noise for beacons from other civilizations.

SETI Projects

Optical SETI

In 2006, The Planetary Society unveiled the first All-Sky Optical SETI (OSETI) telescope. Funded by The Planetary Society and operated by a Harvard University team, it's completely dedicated to capturing that one pulse of light that might be a communication.

SETI Radio Searches

One faint signal from light-years away could prove we're not alone in this universe. The Planetary Society is committed to finding that signal -- tirelessly surveying the skies with our Southern SETI project and our Optical SETI Telescope. You can be a part of these projects and help us keep the search going.

[email protected] is the most successful public participation science project in history, and it is dedicated to searching for a signal from the stars. The Planetary Society made it all possible.
