Will it be: According to a scientist, a foreign ship crossed the solar system

Since October 2017 Robert Werylk discovered that Oumuamua crosses the Solar System, 30,000,000 kilometers from Earth, different assumptions tried to explain what is this interstellar object captured by the Pan-STARRS 1 telescope. A comet, with the name of C / 2017 U1. after confirming that it was not active, was considered an asteroid and was named A / 2017 U1.

A new study shows the possibility of an extraterrestrial spacecraft being treated.

A Harvard University study, which will be published on November 12 in The Astrophysical Journal Letters, suggests that the subject "may be a sampler deliberately sent to the Earth by an extraterrestrial culture," NBC said.

The work of Avi Loeb, head of the Institution's Astronomy Department, and Shmuel Bialy, a Harvard-Smithsonian Center for Astrophysics researcher, does not immediately indicate that the aliens sent the supposed ship. "But after careful analysis of how the interstellar object accelerated as the sun passed at full speed, they say that Oumuamua may be a spacecraft moving from space through the light that falls on its surface," she said. source.

Loeb and Bialy described it in this way: "If we consider an artificial origin, one possibility is that Oumuamua is a solar sail that floats in space to the debris of some advanced technological equipment." Alternatively, a more exotic scenario is that Oumuamua is a fully functional catheter, "the Universe said today.

The high velocity and orbit of this reddish object show, according to scientists, that it does not belong to the solar system. But its flat and taut shape, which has been compared to a cigar, does not conform to known bodies or phenomena.

"It is impossible to assess the purpose behind Oumuamua without further details," said Loeb at NBC. One possibility is that it was floating when it struck the Solar System, "like a ship hitting a web on the surface of the ocean."

Loeb is a specialist in solar cloths, which are also called light photons: they are space launching instruments (for now, as far as they are known by the Earth), consisting of a large surface composed of very light reflexive sheets – hence the name candle – They use sunlight to propel themselves. In his opinion, he added, Oumuamua would be an "exotic".

"We explain the excessive acceleration of Oumuamua away from the sun as a result of the power that the sun is driving on its surface," said Universe Today. "To explain the acceleration measurement, the object must be extremely thin, such as a fraction of a millimeter thick, but with dozens of expansion measures, makes it lightweight relative to its surface and allows it to act like a solar cloth, its origin it could be natural or artificial ".

Although some of their colleagues criticized them for lack of evidence as their case is speculative, Loeb defended himself before NBC arguing that in his lack of evidence his work is based on "I follow the maximum of Sherlock Holmes: What remains, however unlikely, must be the truth. "

An additional problem for Harvard research is that Oumuamua has already abandoned the Solar System and can not see it with telescopes. However, Loeb said that having noticed the object, astronomers would have to start looking for a similar one.

Loeb added to the Universe today: "Oumuamua could be a sample of extraterrestrial technology that has come to explore our solar system, just as we hope to explore Alpha Centauri using Starshot and similar technologies." The alternative could be "to imagine that Oumuamua was on a recognition mission".
