The Galileo Project, the Harvard-based scientific initiative founded by astrophysicist Avi Loeb, released its first year of systematic observational data in July 2024.
The project's rooftop observatory at Harvard, equipped with cameras, infrared sensors, radio receivers, and audio detectors in continuous all-sky mode, logged more than 100,000 aerial events over twelve months. The automated pipeline flagged approximately 800 for human review. A scientific review board identified 37 that remained anomalous after exhaustive cross-referencing against weather data, flight tracking databases, and satellite catalogs.
The most puzzling subset — roughly a dozen events — combined unusual kinematics with spectral signatures unlike any catalogued aircraft, drone, balloon, or meteorological phenomenon.
Loeb was careful to note that the absence of confirmed extraterrestrial technology in the first-year dataset was not surprising. "We are building the evidentiary infrastructure that science requires," he said. "We are still in the evidence-collection phase."
