Boston, MA, United States (4E) – The cigar-shaped "interstellar object" that crashed near Earth a year ago could truly be a reconnaissance probe claimed two Harvard Researcher in a recently published study.
This fantastic and much ridiculed explanation of the true nature of this mysterious piece "Rock", which was baptized by astronomer "Oumuamua", was published by Shmuel Bialy and Prof. Abraham Loeb at the Harvard Smithsonian Center for Astrophysics.
These researchers claim that Oumuamua, in their recent study, "Could Solar Radiation Pressure Explain Oumuamua's Unusual Acceleration?" Have an "artificial origin" near an alien civilization. "They were based on their conclusion on Oumuamua's" excessive acceleration "or the unexpected acceleration when she came through our solar system in January 201
In particular, they believe that Oumuamua is actually a "light sail spaceship". A light sail is a kind of spacecraft that relies on radiation pressure acting on massive "sun sails" to generate propulsion.
"Considering an artificial origin, one possibility is that" Oumuamua is a light sail that floats in interstellar space as the debris of advanced technological equipment, "Bialy and Loeb wrote, suggesting that the object is powered by solar radiation
"Sights of similar dimensions were designed and constructed by our own civilization, including the IKAROS project and the Starshot Initiative, and the Light-Sail technology can be used extensively to transport charges between planets or between stars . "
Another possibility is that this puzzle object is debris of advanced technological equipment, both scientists suspect the high speed of` Oumuamua & # 39 ;, and its unusual trajectory may be due to its inoperability.
"This would d The various anomalies of & # 39; oumuamua explain how the unusual geometry derived from its light curve, its low thermal emission, which indicates a high reflectivity, and its deviation from a Kepler orbit without evidence of comet tail or spin – around torques. "
& # 39; Oumuamua is the first object ever seen in our solar system whose origin is known elsewhere.
Astronomers first thought that Oumuamua was just a comet or an asteroid coming from our planet Comets are known to increase their velocity due to a process known as "outgassing," in which the sun warms the surface of the frozen comet, releasing molten gas. "Oumuamua, however, did not have a" coma ".
Bialy and Loeb rejected the degassing explanation and caused the inexplicable acceleration of Oumuamua. They said that if Oumuamua was indeed a comet, why did not he experience outgassing when he was closest to our sun?
They also cited other studies that show that if outgassing would be responsible for the acceleration, this too would have been a cause of rapid development in Oumuamua's spin that was not observed.
Oumuamua, officially designated 1I / 2017 U1, was discovered on 19 October 2017 by Robert Weryk using the Pan-STARRS telescope at Haleakala Observatory in Hawaii, or 40 days after it reached its next position in the sun.
Since its discovery, `Oumuamua has shown actions that are not consistent with a boulder racing mindlessly through space. For this reason, the scientists were undecided to explain the actions, unusual features and exact origins of Oumuamua.
Scientists called this thing that has fallen through space first a comet and then an asteroid. Disagree, they made `Oumuamua the first member of a new class of things. They called it an "interstellar object".
`Oumuamua is an elongated, dark red object that, despite its proximity to the sun, shows no signs of a comet's tail or coma. It is ten times as long as wide and staggers at speeds of 315,000 km / h.
