The Galileo Project

The Galileo Project is the field’s bet on a single, unglamorous idea: stop arguing about old videos and blurry testimony, and start collecting new, clean, calibrated data that anyone can check. Whether or not it ever finds anything, that methodology is its real proposition.

What it was

The Galileo Project was founded in 2021 by [[avi-loeb]], the Harvard astrophysicist, in the wake of two events: the passage of the interstellar object 'Oumuamua, which Loeb argued might be artificial, and the U.S. government’s June 2021 UAP assessment. Its premise is that the question of non-human technology should be approached the way astronomers approach any phenomenon — with dedicated instruments and statistics, not anecdotes.

In practice that means building observatories: arrays of optical and infrared cameras, radio sensors, and microphones, run by automated software and machine-learning classifiers, that continuously record the entire visible sky and flag anything that doesn’t match a known plane, bird, balloon, or satellite. The first such system was installed on the roof of the Harvard College Observatory. The project also pursues the study of interstellar objects, including a much-debated expedition to recover possible meteorite fragments from the Pacific seafloor.

Why it matters

Galileo’s significance is methodological, and it is the cleanest expression of the instrument-first turn in UAP research. By generating its own calibrated, open, peer-reviewable data, it sidesteps the central weakness of nearly every famous case in this field guide — that the evidence was captured by sensors built for other purposes, by witnesses who weren’t expecting it, and can therefore always be disputed. A purpose-built observatory removes that excuse in both directions: it can confirm an anomaly or, just as usefully, explain one away.

The skepticism is pointed. Critics — including fellow scientists — argue Loeb sometimes overstates the significance of ambiguous findings (the 'Oumuamua and seafloor-spherule claims remain contested), and that the project’s framing risks promising more than calibrated cameras can deliver. Years in, it has produced data and methods but no confirmed anomalous craft.

For this field guide, the Galileo Project is the scientific-search model in its purest form — the academic counterpart to the policy-focused [[sol-foundation]], and a standing argument that the way out of a century of disputed photographs is not better disclosure but better instruments.
