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.
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.
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.
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.
