At first, Oumuamua was written off as a comet or asteroid by some scientists, but others believe it belongs in a new class of "interstellar objects".More news: Ill Maurizio Sarri unhappy with Chelsea performance in Belarus
"It is impossible to guess the objective behind Oumuamua without more data", Avi Loeb, chairman of Harvard's astronomy department and a co-author of the paper, told NBC News MACH in an email. There's limited data on 'Oumuamua, since scientists could only observe it for about two weeks before it zipped beyond our solar system. The object named "Oumuamua" drew the attention of the astronomers of the world as it had an unusual look and behavior.
Recent claims by Harvard University researchers that an interstellar rock, zooming through our solar system, might have been sent by aliens has been dubbed an "outlandish idea" by astrophysicists. And even if the shape could hold up against interstellar weathering, it would still be a form unlike anything that exists on Earth, or anything that could exist under the currently-understood laws of astrophysics.More news: Trump Won the Midterms.

"Light-sails with similar dimensions have been designed and constructed by our own civilization, including the IKAROS project and the Starshot Initiative". Some people point out that the speed of displacement of Oumuamua is compatible with that of a "comet " expelled" from his system, others criticise the method of calculation, recalling that the thesis of the space probe was discarded after the discovery of the meteor. When took in comparison with the regular asteroids and comets, it appeared to be very odd.

Multiple telescopes focused on the object for three nights to determine what it was before it moved out of sight. "It's just like wind hitting a sail", except instead of wind, it's light propelling the object forward.On Nov. 1, Bialy and Loeb released a pre-print of a paper, to be published The Astrophysical Journal Letters later this month, exploring the solar-radiation hypothesis. "The evidence about 'Oumuamua is not conclusive but interesting". "Like many researchers, I would very much like to believe that there is irrefutable proof of extraterrestrial life, but that is not the case", says Alan Fitzsimmons, astronomer at Queens University.
