Listening for Intelligent Life: The Evolving SETI Path from Project Ozma to NIROSETI

To the point

Researchers search for extraterrestrial intelligence by listening for radio and infrared signals from space, a field that began with Frank Drake’s Project Ozma and now combines huge telescopes like FAST, networks such as the Allen Telescope Array, and citizen science through SETI@home to balance targeted searches for habitable-zone exoplanets with broad surveys and rigorous follow-ups to rule out false signals, while exploring what signs of intelligence would look like, who should fund the effort, and humanity’s potential reaction to contact.
