(NewsNation) — The Harvard professor raising questions about the 3I/ATLAS comet passing through our solar system says the hurtling object is giving off chemical signals that do not appear to be natural.

Theoretical physicist Avi Loeb says the Keck II telescope in Hawaii recently collected data that indicates 3I/ATLAS is emitting nickel but little, if any, iron, a characteristic “we only find in industrially produced nickel alloys.” Such a compound is used in metal coatings to fortify surfaces, the New York Post notes in its own interview with the astrophysicist.

Loeb has become a familiar figure in news coverage about 3I/ATLAS because of his startling theory that the comet could be some form of alien tech. For months, he has been highlighting the object’s lack of a traditional comet’s ta
