New Harvard Examine Suggests ‘Oumuamua Is of Alien Origin

"Considering an artificial origin, one possibility is that 'Oumuamua is a lightsail, floating in interstellar space as a debris from an advanced technological equipment", researchers wrote in the paper.

A handout image of an artist's impression released by the European Space Agency (ESA) shows Oumuamua - the first interstellar object discovered in the Solar System - June 27, 2018.

"This unusual object ... is less than [400 metres] in diameter and is moving remarkably fast", NASA said at the time.

Shmuel Bialy and Abraham Loeb from the Harvard Smithsonian Center for Astrophysics suggested the elongated asteroid might have an "artificial origin".

Governments do have secret plans in place for the possibility of an alien landing, but they'd fall apart instantly if it ever actually happened, an astronomer has told LBC.

Oumuamua's unusual trajectory and high speed sets it aside from other space objects such as asteroids and comets.

"It is impossible to guess the goal behind Oumuamua without more data", Loeb was quoted as saying.

"The likelihood of Galactic panspermia is strongly dependent upon the survival lifetime of the putative organisms as well as the velocity of the transporter", according to a paper published in The Astronomical Journal by Manasvi Lingam and the aforementioned Loeb. SETI, the Search for Extraterrestrial Intelligence, tried to detect signals from the object, but found nothing.

Despite the Harvard researchers' work, most scientists, NBC News says, are urging caution in assuming there's any other civilization beyond Earth's atmosphere - and that it's actively seeking us out.

Another alternative? It was an actual alien spacecraft sent to observe Earth. "Carl Sagan once said, "extraordinary claims require extraordinary evidence" and this paper is distinctly lacking in evidence nevermind extraordinary evidence".

'Oumuamua also travels in a complex tumbling spin, but a functioning solar sail would have a much smoother path and obvious radiation-driven acceleration, Jackson said.

The object shot past our Sun last October, being observed as something literally from out of this world (i.e. not from our solar system). "You have to understand that for scientists, the craziest idea is always publishable, as long as there is a tiny chance that it is not wrong", she wrote on Twitter.

Of course, the pair aren't claiming that Oumuamua's definitely of alien origin. "Even the authors probably do not believe it themselves".

The truth may be hard to establish, as Oumuamua has left the solar system and is no longer visible even with telescopes. "It is impossible to guess the objective of Oumuamua without more data".
