Harvard physicist plans expedition to find ‘alien artefact’ that fell from space

A prominent Harvard physicist is planning a Pacific expedition to find what he thinks might be an alien artefact that smashed into the ocean.

Avi Loeb announced that he is organizing a $1.5m ocean expedition to Papua New Guinea to look for fragments of an object that crashed off the coast of its Manus Island in 2014.

Loeb noticed the object in 2019 and identified it as the first interstellar meteor ever discovered - meaning it originated outside our solar system. According to Loeb, the meteor's interstellar origin was confirmed to Nasa in April 2022 by the Department of Defense's space command.

Loeb and his team also concluded that the meteor was tougher than all other 272 meteors in Nasa's Center for Near Earth Object Studies catalog.

"Intrigued by this conclusion, I established a team that designed a two-week expedition to search for the meteor fragments at a depth of 1.7km on the ocean floor. Analyzing the composition of the fragments could allow us to determine whether the object is natural or artificial in origin," Loeb wrote in a post on Medium.

"We have a boat. We have a dream team, including some of the most experienced and qualified professionals in ocean expeditions. We have complete design and manufacturing plans for the required sled, magnets, collection nets and mass spectrometer," he added.

The ocean expedition is expected to use a ship with a magnetic sled deployed using a long line winch. The team will consist of seven sled operations, as well as a scientific team.

The size of the fragments to be potentially found by Loeb's team will depend on the composition of the meteor. For an iron meteorite, the physicist predicts about a thousand fragments larger than a millimeter. If the meteor is of stainless-steel composition, Loeb's team expects to find larger sizes with tens of fragments larger than a centimeter.

Loeb said that in case his team recovers a "sizable technological relic" from the expedition, he promised Paola Antonelli, the curator of the Museum of Modern Art, that he will bring it to New York for display.

The expedition is expected to launch this summer, the Daily Beast reports.

"There is a chance it will fail," Loeb, who is co-founder of the $1.755m Galileo Project that is tasked with searching for extraterrestrial signs, told the outlet. Nevertheless, he remains adamant about the mission.

"Extraordinary claims require extraordinary evidence," he said.
