Physicist leads search for extraterrestrial artifact from space.
Harvard physicist Avi Loeb is organizing a $1.5m ocean expedition to Papua New Guinea to search for fragments of an object that crashed off the coast of Manus Island in 2014, which he believes could be an alien artefact. Loeb and his team identified the object as the first interstellar meteor ever discovered, and concluded that it was tougher than all other 272 meteors in NASA's catalog. The expedition will use a ship with a magnetic sled to search for fragments at a depth of 1.7km on the ocean floor. Loeb said that if his team recovers a "sizable technological relic," he will bring it to the Museum of Modern Art in New York for display.
