Scientists have been intrigued by the origin and nature of ‘Oumuamua since its discovery in 2017. The passage of this strange fireball through the Solar System in 2017 made some astronomers think it could be a sign of extraterrestrial life, a controversial but still defended thesis. by renowned scientist Avi Loeb, whose essay was published this Thursday.
What does Avi Loeb’s essay suggest?
“If I’m right, it’s the greatest discovery in human history,” says Avi Loeb, director of the astronomy department at Harvard University.
In his essay The First Sign of Extraterrestrial Intelligent Life, this black hole expert explains how the detection of Oumuamua, a cigar-shaped object that roamed the Solar System, unfolded in October 2017.
How did they detect Oumuamua?
Oumuamua was detected by the Pan-STARRS1 telescope in Hawaii, Oumuamua – which means “messenger” in Hawaiian – measures 400 meters long and 40 meters wide. Its speed was so high that it could only come from a distant star: it was the first object detected that came from another star system.
Oumuamua, was listed as an asteroid by NASA
After describing it as an asteroid, a team from the European Space Agency estimated that it was likely a comet.
Oumuamua may be an alien anomaly, according to Avi Loeb
However, Harvard University astrophysics professor Avi Loeb went a step further and cataloged this new discovery as the first evidence of extraterrestrial life and technology in space . This divided the scientific community.
Avi Loeb has cataloged this new discovery as the first evidence of extraterrestrial life and technology in space.
Currently, Oumuamua is treated as an interstellar asteroid that comes from another cosmic system, unique in our solar system, but something created naturally.
“Our Solar System was recently visited by advanced alien technology from a distant star” is what Professor Avi Loeb has stated bluntly that on February 3 he will publish in our country ‘Extraterrestrial: Humanity at the first sign of intelligent life beyond la Tierra ‘ a book where he presents his theory to the general public for the first time and describes the profound implications it has for science, religion, the future of our species and our planet following this discovery.

Along with another Harvard researcher, he signed a paper in the Astrophysical Journal Letters , espousing the theory that Oumuamua could only be a probe propelled by an extraterrestrial civilization. Its publication was widely criticized, but for Loeb the “debate continued for lack of tangible evidence”. “It only turns out” that the phenomenon “was and continues to be an anomaly”.
Over 272 pages, the American-Israeli physicist lays out his hypotheses about “this first interstellar visitor ever identified” and “explores the question of whether we are alone in the Universe”, according to French publisher Seuil. He also advocates expanding the field of research, in addition to studying possible microbial life on Mars, the goal of NASA’s “Perseverance” mission, which will land on the red planet on February 18.
