Introduction
The Galileo Project does not accept public UFO photographs or videos as research evidence because its scientific strategy depends on data collected by calibrated instruments operating under known conditions. In the project’s view, even a striking image is of limited scientific value if researchers do not know exactly how it was captured, what the sensor was doing at the time, whether the image has been processed, or what other instruments recorded simultaneously. Rather than sorting through existing sightings after the fact, the project seeks to build its own stream of observations using dedicated observatories that continuously monitor the sky and record extensive metadata alongside the imagery. This policy is not a judgement on the sincerity of witnesses. It is an evidence standard designed to produce measurements that can be independently checked, compared and reproduced.

What Outside Photos Usually Lack
Most UFO photographs arrive with substantial unknowns. Researchers often do not know the exact camera settings, lens characteristics, compression history, environmental conditions or chain of custody of the file. In many cases, they also lack crucial context such as radar data, distance measurements, atmospheric conditions and simultaneous observations from independent sensors.
For the Galileo Project, these missing elements make it difficult to determine whether an image shows an unusual object, a conventional aircraft, an optical artefact, a nearby insect, a balloon, sensor noise or a processing error. A single photograph may capture something unexpected, but it rarely provides enough information to reconstruct the object’s true size, speed, distance or physical nature. The project’s stated goal is therefore not to collect more ambiguous images but to acquire data capable of ruling out ordinary explanations.

The project’s FAQ explicitly states that it is not accepting outside photos or videos because it seeks information that is “high-quality, reliable, consistent, calibrated and comparable.” It similarly distinguishes its research programme from the collection of anecdotes and public sightings.

Why Calibration and Metadata Matter
The central issue is not whether a photograph looks convincing. The issue is whether the observation can be measured.
Calibration means that researchers understand precisely how an instrument responds to the world. They know its sensitivity, field of view, distortions, timing accuracy and operating state. Metadata records the circumstances of the observation, including timestamps, location, instrument settings and environmental conditions.
Without calibration and metadata, many basic scientific questions become difficult or impossible to answer:
- Was the object large and distant or small and nearby?
- Was apparent motion caused by the object or by camera movement?
- Was the image altered by compression, sharpening or digital processing?
- Did other sensors observe the same event?
- Can another team independently verify the result?
The Galileo Project’s observatory architecture was designed specifically to address these questions. Its technical papers repeatedly identify poor data quality, missing metadata and uncalibrated observations as major obstacles in UAP research. The project’s computing and data-management systems are built around preserving provenance information and maintaining a documented chain from observation to analysis.

This emphasis reflects a broader trend in official and scientific UAP studies. Galileo founder Avi Loeb has argued that claims of extraordinary phenomena require exceptionally well-characterised measurements and that archival reports from unknown or poorly documented sensors rarely meet that standard.

Why Galileo Prefers New Observations to Archival Sightings
A common assumption is that a scientific UFO project would begin by examining the vast collection of existing photos and videos. Galileo largely rejects that approach.
The project’s philosophy is that retrospective analysis is constrained by whatever information happens to survive. If an important measurement was never recorded, no amount of later investigation can recover it. A photograph taken years ago cannot be re-observed under controlled conditions. Missing sensor data remain missing.
Because of this limitation, the Galileo Project was conceived as a forward-looking observatory effort. Its public descriptions emphasise collecting new open scientific data with purpose-built instruments rather than relying on historical reports, classified material or anecdotal evidence. The goal is to generate observations whose quality is known from the moment they are captured.

This approach also avoids endless debates over authenticity. Instead of asking whether an old image is genuine, researchers can examine a freshly recorded event whose instrumentation, calibration records and processing history are already documented.
How Galileo Creates Its Own Evidence Stream
The rejection of outside photos is paired with an alternative: continuous, instrumented observation.
Galileo’s observatories are designed to collect multimodal data rather than isolated images. The system combines optical and infrared cameras with additional sensors and software intended to classify ordinary objects and identify anomalies. Its observatory architecture places heavy emphasis on synchronised measurements, sensor characterisation and long-term monitoring. [arXiv]arxiv.orgOpen source on arxiv.org.
A key advantage of this approach is cross-validation. If an unusual object appears, researchers can compare multiple simultaneous data sources instead of relying on a single frame from a single camera. Observatory systems can also be recalibrated, tested against known targets and evaluated against large baseline datasets of aircraft, satellites, birds, weather phenomena and other routine sky traffic.

The project’s first observatory generated data on hundreds of thousands of detected aerial objects, providing a reference catalogue of normal sky activity. From Galileo’s perspective, this background census is essential because anomalies can only be identified reliably when researchers understand what ordinary observations look like.

The Policy Behind the Photo Policy
Galileo’s refusal to accept public UFO photos is fundamentally a governance choice about evidence quality. The project is attempting to move UAP research away from witness-centred investigation and towards observatory-based measurement.
Under this framework, an image is not valuable because it is dramatic or unexplained. It becomes valuable when it is accompanied by enough calibrated information to support rigorous analysis. The project therefore prioritises controlled data acquisition over crowd-sourced submissions, believing that scientific progress is more likely to come from systematically collected measurements than from attempting to interpret isolated photographs whose observational context is largely unknown.
