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.
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.
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.
SETI@home 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.
Several readers have contacted me recently about reports that a group of international astronomers have detected a strong signal coming from a distant star that could be a sign of a high-technology civilization. Here’s my reaction: it’s interesting, but it’s definitely not the sign of an alien civilization—at least not yet.
The Planetary Society sponsored all-sky optical SETI search at Harvard University went off the rails, telescope roof rails that is, but it is back on track and hunting the sky for ET.

Cosmos returns in fine form in its penultimate episode. Sagan explores the historical and scientific precedents for the search for extraterrestrial life (SETI) and our human desires to not be alone in the universe.
An update on the Planetary Society's improved Optical SETI search, with Harvard's Paul Horowitz and Curtis Mead.
The Planetary Society Optical SETI (OSETI) Telescope was successfully upgraded and fully tested, and is now fully operational looking for aliens. Here are some updates on the performance and progress. In summary, the upgraded telescope is performing just as hoped and is scanning the skies.
The Planetary Society Optical SETI Telescope in Harvard, Massachusetts just got a major upgrade of its electronics.

Remember SETI@home? The ground-breaking computing project is now taking a look at candidate Earth-like planets that have been detected by NASA's Kepler space telescope.
Citizen Science projects let volunteers easily contribute to active science programs. They're useful when there is so much data it overwhelms computing algorithms (if they exist) or the scientific research team attempting to process it.
