Prof. Avi Loeb — Harvard Baird Professor of Science. Longest-serving Chair, Harvard Astronomy (2011-2020). Founding Director, Harvard Black Hole Initiative. Former Chair, Board on Physics and Astronomy, National Academies. Former Member, President’s Council on Science and Technology. GALILEO PROJECT (founded July 2021): Multi-sensor UAP observatories; half a million sky objects catalogued by November 2024; seeks volunteers for AI object classification. OUMUAMUA (October 2017): First confirmed interstellar object. Anomalies: extreme elongated shape unlike any natural object, no cometary tail despite non-gravitational acceleration away from the Sun. Loeb/Bialy 2018 paper: could be an artificial solar sail. Scientific consensus: likely natural. IM1 (January 8, 2014): First confirmed interstellar meteor, identified by Loeb and Siraj. Confirmed by US Space Command via DoD satellite sensors in April 2022 memo. Highest material strength of any meteorite in NASA’s CNEOS catalog. PACIFIC EXPEDITION (June 2023): Using a deep-sea magnetic sled, Loeb’s team recovered 850 metallic spherules from the Pacific floor near Papua New Guinea, at IM1’s estimated impact site. 85 km north of Manus Island. Funded by $1.5M grant from Charles Hoskinson. Early analysis: “BeLaU” composition (extremely high abundances of Beryllium, Lanthanum, and Uranium) — “unprecedented in the scientific literature.” Iron isotope ratios unlike Earth, Moon, or Mars. Counter-claim: October 2023 study said coal ash. Loeb rebuttal: 55-element comparison shows clearly different. September 2025 paper: “BeLaU Spherules from an Interstellar Meteor Site in the Pacific Ocean are Not Common Terrestrial Materials.” 3I/ATLAS (July 1, 2025): Third confirmed interstellar object — detected by NASA-funded ATLAS telescope in Chile, approaching from Sagittarius constellation at interstellar velocity. Currently active area of Loeb’s research.
