We may not be alone in the universe, according to some astronomers at Harvard University.
A mysterious, cigar-shaped object that has floated through space could have been sent by an "alien civilization". "According to researchers from the Harvard Smithsonian Center for Astrophysics.
The object nicknamed "Oumuamua" was originally discovered in October 2017 in Hawaii by the Pan-STARRS 1 Telescope. The word "Oumuamua" in Hawaiian means "a messenger from the distant past". "According to CNN.com .
The object aroused interest among many scientists as it has an unusual shape, an unknown origin and a particular pattern of movement (not like comets and asteroids). The researchers originally called the object a comet, then an asteroid, before landing on an "interstellar object".
In their paper, which was submitted to the Astrophysical Journal Letters the researchers said, "Oumuamua may be a fully functional probe that was purposely sent by an extraterrestrial civilization to near Earth , The newspaper describes it as an "elongated dark red object" that is ten times as long as it is wide and was already traveling "at speeds of 1
Although this does not suggest that the Earth will soon be occupied by aliens, the researchers speculate that the unique shape and motion of the object could mean that "Oumuamua could come from somewhere outside of our solar system."
"Considering an artificial origin, it is possible that 'Oumuamua is a lightweight sail that floats as an inter-linked space from an advertisement outdated technological equipment," it says in the newspaper. "Sails of similar dimensions were designed and constructed by our own civilization, including the IKAROS project and the Starshot Initiative. The Light-Sail technology can be used extensively for transporting charges between planets or between stars. This would explain the various anomalies of & # 39; Oumuamua, such as the unusual geometry that derives from its light curve, its low thermal emission, which indicates high reflectivity, and its deviation from a Kepler orbit without evidence of comet's tail or Spin-Ups Torques.
