Professor Avi Loeb (Harvard) leads the Galileo Project, which explicitly combines the search for technosignatures with UAP research. In June 2023, Loeb led a $1.5 million expedition to the Pacific Ocean to recover material from IM1 — the first confirmed interstellar meteor, detected January 8, 2014. US Space Command formally confirmed interstellar origin to NASA at 99.999% confidence based on satellite velocity measurements. The expedition recovered 850 sub-millimeter spherules from the seafloor near Papua New Guinea. Approximately 10% showed a “BeLaU” (Beryllium, Lanthanum, Uranium) composition described as “unprecedented in the scientific literature” — different from any known solar system material, Earth, Moon, or Mars samples. Iron isotope ratios also differed from solar system norms. A September 2025 Harvard paper confirmed BeLaU spherules are not common terrestrial materials, ruling out the coal-ash contamination hypothesis. The debate continues but the evidence for unusual extrasolar composition is peer-reviewed. Then: 3I/ATLAS — the fourth interstellar object — was detected July 1, 2025 by the ATLAS telescope in Chile. Loeb published dozens of analyses through early 2026 noting anomalous properties: a sunward glow “ten times longer than it is wide,” wobbling jets, extreme non-gravitational deceleration, anomalous deuterium abundance, and particles “much bigger than common sunlight-scattering dust.” In March 2026 Loeb explicitly stated: “Strong Non-Gravitational Breaking by Interstellar Objects is a Technological Signature!” The Galileo Project is also building an observatory network specifically monitoring UAP and is seeking volunteers to help label sky images for unidentified objects (February 2026).
