A Panoramic All-sky All-time Near InfraRed and Optical Technosignature Finder

Overview Why PANOSETI? Instrument Astrophysical Transients Gallery Publications Team

PANOSETI is a novel experiment designed to greatly expand the current optical and near-infrared SETI phase space by monitoring the entire observable sky during all observable time, in order to search for nanosecond to second pulsed light signals and astrophysical transients. PANOSETI instrumental design, based upon an assembly of dozens of Fresnel-lens telescopes equipped with fast (nanosecond-speed) detectors, is summarized in the table below.
