This mysterious object, spotted tumbling through our solar system previous year, may have been an alien spacecraft sent to investigate earth.
The object, nicknamed the "Oumuamua", meaning "messenger, which stretches from the distant past" in the Hawaiian Islands, was first discovered in October 2017, the telescope Pan-STARRS 1 in Hawaii.
IThe theory is based on the object's "excess acceleration", or its unexpected boost in speed as it traveled through and ultimately out of our solar system in January 2018. But now Harvard scientists say Oumuamua may literally be an alien spacecraft sent from another galaxy to spy on us, reports NBC News.
Not only is it the first-ever interstellar asteroid or comet detected by astronomers while passing through the solar system, its shape is odd, its acceleration is unexpected, and a cometary tail - the signature trail of particles seen behind shooting stars - is conspicuous in its absence. Its flattened, elongated shape and the way it accelerated on its way through the Solar system, distinguished him from ordinary asteroids and comets.
The scientists also noted that light-sails with similar dimensions have originated on earth.
Jackson said the spectral data from 'Oumuamua looks like an asteroid or a comet, while that of a solar sail would look very different. "Technology the light sails can be used to transport cargo between planets or between the stars", the researchers note. But Oumuamua wasn't "coma", of the atmosphere and dust that surround the comet, when they melt.
Dead Brothel Owner Dennis Hof Wins Nevada Assembly Election
The Love Ranch brothel that Hof owned became notorious as the place where former Laker Lamar Odom was found unconscious in 2015. Under Nevada law, Republican county officials will appoint someone to serve the term in the Assembly to which Hof was elected.
"For decades we've theorized that such interstellar objects are out there, and now―for the first time―we have direct evidence they exist", said Thomas Zurbuchen, associate administrator for NASA's Science Mission Directorate in a 2017 news release.
Mr Bailer-Jones led a group of scientists earlier this year who identified four dwarf stars as likely origin points for Oumuamua.
A new study as found a huge cigar-shaped object travelling through space could be an alien spaceship.
"This is the only other explanation we could come up with", said Avi Loeb, chair of Harvard's department of astronomy. "Bailer-Jones" paper on possible origin sites for 'Oumuamua was accepted by the Astrophysical Journal in September. Loeb calculated that for it to be a random object following a random orbit, there would have to be 100 million times more of its type hanging around in the solar system.
Another alternative? It was an actual alien spacecraft sent to observe Earth.
Astronomers were baffled, eventually settling on the term "interstellar object", the Washington Post reported.
