Scientists reveal mysterious 'Oumuamua' object could be an alien spacecraft

Scientists reveal mysterious 'Oumuamua' object could be an alien spacecraft

According to the researchers, the object's unusual, elongated shape and unexpected trajectory ruled out conventional possibilities, including an asteroid.

It was moving at 59,030mph when it was first tracked by scientists.

The idea that the object could have been part of some massive alien solar-powered technology may seem far-fetched, but the authors suggest an even more "exotic" explanation: "that Oumuamua may be a fully operational probe sent intentionally to Earth vicinity by an alien civilisation".

What we do know is the Oumuamua is the first object ever seen in our solar system that is known to have originated elsewhere.

A new paper from the Harvard scientists Shmuel Bialy and Abraham Loeb suggests that quirks in Oumuamua's rotation and speed could be the result of solar-powered movement.

Using a mathematical analysis of the way the object sped up as it shot past the sun, the researchers argue that Oumuamua could be a spacecraft pushed through space by light falling on its surface - a kind of "lightsail of artificial origin", NBC News reported.

A massive flattened boulder-like object traveling through space with "peculiar acceleration" could be an alien craft, according to a new study.

In a paper to be published November 12 in The Astrophysical Journal Letters, the pair declare that the reddish, elongated, stadium-sized object "may be a fully operational probe sent intentionally to Earth vicinity by an alien civilization", NBC News reported.

Oumuamua baffled scientists a year ago due to its unique speed and trajectory: as it passed through our solar system, Oumuamua accelerated.

"But one should not blindly accept this clever hypothesis when there is also a mundane explanation for Oumuamua - namely that it's a comet or asteroid from afar".

But until science tells us that it definitely isn't, we'd like to believe that it is.

Yesterday, a number of astronomers criticized Loeb's conclusions, particularly the lack of direct evidence pointing to alien influence.

Bailer-Jones, who earlier this year led a group of scientists who identified four dwarf stars as likely origin points for Oumuamua, raised questions in particular about the object's tumbling motion.

"I follow the maxim of Sherlock Holmes: When you have excluded the impossible, whatever remains, however improbable, must be the truth", Loeb said. It's also possible Oumuamua was just created to wander through space, collecting information, and our solar system just happened to be in its way - its operators weren't necessarily looking to pry into the lives of humans.

"Two very capable, very bright astronomers, from a very credible organization, Harvard, have come out with the notion that Oumuamua could be alien in origin", Diamond said.
