Did We Just Witness the Passing of an Alien Space Probe?

  • Scientists dispute 'alien spacecraft' suggestions

"Considering an artificial origin, one possibility is that 'Oumuamua is a light sail, floating in interstellar space as a debris from an advanced technological equipment". According to the paper which was published in the Astrophysical Journal Letters on 12 of November, the researches pointed out that this can be a completely working probe which has been sent here with the intention to observe earth and its surroundings by an alien civilization. Bialy and Loeb believe the object could be a light-sail, which would have used the radiation pressure of starlight - or perhaps even light from a giant laser - to reach the solar system.

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.

That high speed is what the Harvard astronomers are basing their theory on. Further observations gave evidence the object was interstellar in nature, and it left the solar system even faster than it came in after slinging around the sun and reaching 196,000 miles per hour, according to NASA. "These features make Oumuamua weird, belonging to a class of objects that we had never seen before", said Abraham Loeb, from the varsity.

"It is exciting to live at a time when we have the scientific technology to search for evidence of alien civilizations", Loeb wrote in an email. 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. For this to happen, however, 'Oumuamua must less than 1 mm thick and be just a few metres across - which is much smaller and thinner than previously thought. But other astronomy experts aren't buying it.

Democrats disagree on just how aggressively to go after president
The president crowed that Republicans held control of the Senate and then took aim at members of the House , where the GOP lost . Previous presidents who have suffered mid-term setbacks have professed humility and said they learned valuable lessons.


The cigar-shaped space rock which was designated as a comet by astronomers is apparently the first known object from another solar system to pass through our own.

"Like most scientists, I would love there to be convincing evidence of alien life, but this isn't it", Alan Fitzsimmons, an astrophysicist at Queen's University, Belfast, told the AFP.

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