Harvard astrophysicist Avi Loeb believes he has found fragments of an alien spacecraft from a meteor dubbed IM1, which crashed off the coast of Papua New Guinea in 2014.

He oversaw a $1.5 million expedition that found 50 tiny spherules, believed to be a steel-titanium alloy, on the Pacific Ocean floor. These objects are much stronger than the iron found in regular meteors, leading Loeb to suggest they may have interstellar origins or could have been made by an advanced extraterrestrial civilization. The findings will be taken to Harvard for further testing.

Loeb, known as the "alien hunter of Harvard," has been controversial for his belief in extraterrestrial life, previously claiming a space rock visible in 2017 was an alien-built technology.
