Harvard Researchers: Space Object Was Alien Spacecraft

  • An artist's depiction of Oumuamua the first detected interstellar object

A mysterious cigar-shaped object spotted tumbling through our solar system a year ago may have been an alien spacecraft sent to investigate Earth, astronomers from Harvard University have suggested.

A soon to be released paper written by researchers Shmuel Bialy and Abraham Loeb from the Havard Smithsonian Center for Astrophysics points to the change in speed as Oumuamua passed and left our solar system - odd behaviour for a rock.

Oumuamua-or "messenger from afar arriving first" in Hawaiian-was first discovered in October 2017 by the Pan-STARRS 1 telescope in Hawaii.

Now, a new paper by researchers at the Harvard Smithsonian Center for Astrophysics raises the possibility that the elongated dark-red object, which is 10 times as long as it is wide and traveling at speeds of 196,000 miles per hour, might have an "artificial origin". Whether Oumuamua was something natural, an old piece of busted technological junk, or extraterrestrial visitors, we'll probably never know for sure.

The cigar-shaped rock is now speeding through the galaxy and is the first known interstellar object to enter our solar system.

Since scientists could not explain its unusual shape and the exact origin, so at first called it a comet, and then an asteroid before giving it a title: a new class of "interstellar objects".

Light sail technology has already been developed by scientists here on Earth, such as Japan's IKAROS project and the Starshot Initiative, the authors write.

An artist's depiction of Oumuamua, an interstellar object that astronomers believe is a comet, not an asteroid. 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. But Oumuamua wasn't "coma", of the atmosphere and dust that surround the comet, when they melt.

A new study as found a huge cigar-shaped object travelling through space could be an alien spaceship.

In a letter published in The Astrophysical Journal Letters on 12 November, the researchers add that Oumuamua could be a spacecraft pushed along by light falling on its surface.

After using telescopes to determine if Oumuamua was an asteroid or comet, researchers settled on the term artificial origin because of its "excess acceleration" and "highly hyperbolic trajectory". Do you think the interstellar object was actually an alien probe?

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

In December 2017 it was announced the astronomers were going to scan Oumuamua for signs of alien life.
