Manus Island: Galileo Project finds IM1 spherules
Harvard astronomer Avi Loeb's Galileo Project expedition recovered over 50 unusual sub-millimeter spherules from the Pacific Ocean floor near Manus Island, linked to the 2014 interstellar meteor IM1. Analysis showed high iron content with traces of other elements, sparking scientific debate over their origin.
Background
Expedition und Fund From June 14–28, 2023, Avi Loeb, Harvard astronomer leading the Galileo Project, conducted a search in the Pacific Ocean 85 km north of Manus Island, Papua New Guinea. The team targeted debris from the 2014 interstellar meteor CNEOS 2014-01-08 (IM1) using a magnetic sled, recovering more than 50 sub-millimeter-sized spherules.
Analyse und Zusammensetzung Composition revealed approximately 84% iron, 8% silicon, 4% magnesium, 2% titanium, plus traces. Evidence pointed to rapid heating like a meteor fall. Two spherules suggested an age near 14 billion years. In 2024, Loeb reported elevated beryllium, lanthanum, uranium levels compared to chondrites.
Skeptizismus und Alternativen Critics like Matthew Genge (Imperial College) argued linking to the specific fireball impossible, as no micrometeorites from observed events exist. Patricio A. Gallardo (University of Chicago) proposed coal ash; others suggested industrial pollution or nuclear test remnants from Marshall Islands. Monica Grady raised similar doubts.
Bedeutung This event highlights efforts to scientifically probe interstellar origins amid UAP interest, though controversy persists over natural vs. artificial nature.
