Do you remember Oumaamuju, that the asteroid created in the extended form, which got into the solar system last October? Since then, astronomers have been trying to find natural explanations for their physical characteristics. Two Harvard researchers have been more excited about the theory.
Shmuel Bialy and Harvard Smithsonian Astrophysical Center Abraham Loeb recently published an interesting report on the acceleration of Oumoamua when it came to the Solar System. His conclusion is that it is related to a kind of propulsion and point, and not without some certainty that this kind of movement coincides with the light driven by an artificial vehicle.
The movement to which they relate is a rare maneuver that was caused by an asteroid that moved from the sun. After crossing the solar system and going close to our star, Oumamuua slightly changed the trajectory and quickly accelerated its passage unexpectedly. The combined data from Hubble and several terrestrial ecoscopes from ESA and NASA confirmed that the asteroid left our system much faster than expected.
This is exactly Bialy and Loeb's study. Both astrophysicists have figured out the acceleration of Oumoamua in its pathway and, in theory, can be explained by the pressure generated by solar radiation. In other words, the asteroid accelerated due to Sun's surface coil photon pressure.
Researchers play with the idea that the Oumoamua traction system is similar to the Lightsail probes that we explore on Earth. From there, in order to fall that Oumuamua may be the driving force of the future civilization, there is very little to be precise in a few points.
Of course, solar radiation pressure does not mean that Oumuamua is a disguised probe. A study published in Nature in June of the same year explains that an asteroid can cause gas such a small impulse that is caused by the ice that forms Oumuma. Evaporation of ice on its surface releases enough gas to record a small momentum in the opposite direction to the sun (as it is provoked directly in the open part).
The interstellar asteroid Oumuamua has its own natural propulsion system
Its through the solar system was very short, but its stretched shape, like the cigar and its …

A simple natural phenomenon or an exotic motorcycle produced by extraterrestrial civilization? Astrophysicists play with this idea to attract the passion of the community to foreigners. This article and many others that have been published today are a good proof that they have achieved it. If you are one of those who like these topics, I would recommend reading the arthur C. Clarke's wonderful novel Other Con Rama. [Harvard Smithsonian Center for Astrophysics vía Ars Technica]
