A Golden Age of SETI: From Project Ozma to Breakthrough Listen

To the point

It traces the search for life beyond Earth—from early ideas and David Todd to Frank Drake’s Ozma and Carl Sagan’s Arecibo message—into today’s AI‑assisted surveys like Breakthrough Listen that scan thousands of stars for technosignatures across many wavelengths, while grappling with the Fermi paradox and widening the hunt beyond radio to lasers, megastructures, and atmospheric signs on exoplanets, noting that thousands of exoplanets have been found and METI debates continue, all in what many call a golden age of discovery.
