The Galileo Project: A Data-Driven, Open-Data Search for Extraterrestrial Artifacts and Interstellar Objects

To the point

Since 2021, Avi Loeb leads the Galileo Project, an open, data‑driven effort to search for signs of alien technology and unexplained objects near Earth using telescopes, sensors, AI and possibly radar to look for artifacts in orbit, interstellar visitors like 'Oumuamua, and non‑manmade satellites, with Amir Siraj heading the Interstellar Object Studies branch and Alan Stern advising on mission concepts, not ruling out any explanation in advance, a telescope installed at Harvard in 2022 and plans for broader deployment, and while it has drawn media attention and some scientific support, it also faces criticism that it could blur lines between astronomy and fringe ufology.

The Galileo Project - Wikipedia

The Galileo Project, launched in 2021 by Harvard astrophysicist Avi Loeb, is an international, data‑driven initiative to search for extraterrestrial intelligence and technosignatures—including anomalous aerial phenomena—on and around Earth by deploying a network of optical and infrared sensors, existing telescopes, AI‑powered data analysis, and Earth‑observation assets to identify artefacts rather than only signals, with two main research streams led by Amir Siraj on detecting Oumuamua‑like interstellar objects and non‑manmade artificial satellites and with Alan Stern collaborating on mission concepts; the effort began with a telescope atop the Harvard College Observatory in 2022 and plans broader deployment amid ongoing debate following 2023 claims of interstellar material.
