Have Aliens Found Us? A Harvard Astronomer on the Mysterious Interstellar Object ‘Oumuamua

On October 19, 2017, astronomers at the University of Hawaii spotted a strange object travelling through our solar system, which they later described as “a red and extremely elongated asteroid.” It was the first interstellar object to be detected within our solar system; the scientists named it ‘Oumuamua, the Hawaiian word for a scout or messenger. The following October, Avi Loeb, the chair of Harvard’s astronomy department, co-wrote a paper (with a Harvard postdoctoral fellow, Shmuel Bialy) that examined ‘Oumuamua’s “peculiar acceleration” and suggested that the object “may be a fully operational probe sent intentionally to Earth’s vicinity by an alien civilization.” Loeb has long been interested in the search for extraterrestrial life, and he recently made further headlines by suggesting that we might communicate with the civilization that sent the probe. “If these beings are peaceful, we could learn a lot from them,” he told Der Spiegel.

I thought that title rang a bell - then I remembered seeing this recently ...

Professor Avi Loeb is planning to retrieve the meteor through a forthcoming expedition in the coming months in the Pacific Ocean (Papua New Guinea).

Harvard Professor Believes Alien Tech Could Have Crashed Into Pacific Ocean — And He Wants to Find It

There's a video with an interview with Avi Loeb embedded in the article.

A Harvard University professor believes a meteorite that crashed into the Pacific Ocean in 2014 may be made of a material that one would expect to be in their favorite sci-fi movie. Avi Loeb — the longest serving chair of Harvard Universities Department of astronomy — is convinced that this object may be alien technology or a meteorite of unprecedented material strength. None of this is possible to confirm without physically studying the object, so the professor has planned an expedition to retrieve it that will cost over a million dollars in funding from private donors.

"This would be the first time that humans put their hands on the material that makes an object that came from another star."

There was one in particular that sparked the interest of Loeb and his student, Amir Siraj. Based on the speed of the meteor and how much of the object burned upon entry, Loeb determined that it must be made of a material that is tougher than iron.

"And so this one was an outlier in terms of its composition. It was also an outlier in terms of its speed outside the solar system. It moved at least twice as fast as stars move around the sun in the vicinity of the sun."
