Leading the Search for Life and Intelligence Beyond Earth
The SETI Institute is the only research organization solely devoted to searching for and studying life and intelligence beyond Earth.
Our research efforts depend on:
- Ground and space-based telescopes
- Radio telescopes and radio interferometers
- Developing new instruments and technologies
- Laboratory research
- Field expeditions
- Advanced data analytics

Understanding the Drake Equation
N = R* • fp • ne • fl • fi • fc • L
This simple formulation is generally agreed to be the “second most-famous equation in science (after E= mc2),” and you can find it in nearly every astronomy textbook.
Projects
ATA • Radio Astronomy • Hat Creek Radio Observatory • HCRO
The Allen Telescope Array (ATA)
The ATA is the first radio telescope designed from the ground up to be used for SETI searches.
COSMIC • VLA
COSMIC
The Commensal Open-Source Multimode Interferometer Cluster (COSMIC) is a new commensal Ethernet-based digital signal processing backend and computer cluster on the VLA in New Mexico operated through the NRAO.
Unistellar • citizen science • eVscope
Unistellar Network
Leverage your eVscope's power and join a community of users to image intriguing astronomical events such as supernovae and exoplanet transits, while making a valuable contribution to research.
CAMS • Meteors • Meteorites • Comets • Asteroids
Cameras for Allsky Meteor Surveillance (CAMS)
The CAMS network uses an array of low-light video surveillance cameras positioned around the world that keep a constant watch on the night sky.
LaserSETI • Optical SETI
LaserSETI
SETI Institute’s LaserSETI program is building a network of instruments to monitor the entire night sky. This network represents an unprecedented growth in the continuing search for manifestations of sophisticated intelligence beyond Earth.
GNU Radio • Radio Astronomy
GNU Radio and SETI
GNU technology could revolutionize the development of receiving equipment for SETI (and for radio astronomy in general.) It promises to speed the design of new receivers, and to allow scientists to quickly change how data are analyzed and displayed.
