Oumuamua could be a alien spacecraft according to new scientific study

But the current telescope technology available found nothing of note on the asteroid.Still, there were some unusual things about 'Oumuamua: Normally, scientists would assume that an interstellar object would be a comet. However, the flattened and elongated shape of the item and its acceleration as it was approaching the solar system was among the things which made it a stand out.

The paper was written by Abraham Loeb, professor and chair of astronomy, and Shmuel Bialy, a postdoctoral scholar, at the Harvard Smithsonian Center for Astrophysics.

A mysterious cigar-shaped object spotted tumbling through our solar system previous year may have been an alien spacecraft sent to investigate Earth, astronomers from Harvard University have suggested. Named after the Hawaiian word for "scout" to commemorate its interstellar voyage, the cigar-shaped object has both a highly eccentric orbit and a shiny surface, leading some astronomers to identify it as a comet. Japan's IKAROS mission, which launched in 2010, has already used a light-sail to accelerate a spacecraft using sunlight.

They go on to state, "a more exotic scenario is that Oumuamua may be a fully operational probe sent intentionally to Earth vicinity by an alien civilization". 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.

This led us to suggest that it may be a light-sail produced by an alien civilization, Loeb said.

Unfortunately, 'Oumuamua is now too far away from Earth to study further so we may never know its precise nature and origin. Their conclusion: If 'Oumuamua was being propelled by solar radiation, it would have to be less than a millimeter thick, and hundreds of meters long. Yesterday other astronomers criticized Loeb that he had announced this only to draw the attention of the world and for publicity as there was lack of evidence to be an alien influence. His main interest is to have been in 2017, the first object identified in the process of passing through our solar system so that it is not native.

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

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