The secret body will confirm what we already know. We do not know much about its global

Asteroid? The main competences? Barley spaceboat?

About one year after its discovery, Oumuamu's barley-barley body is again the aim of a professional and general public. A number of scientists have reviewed their specific buildings. And he gave an explanation that could exist, which includes a very historic one.

There are three recent surveys with European and American scientists particularly specific. At the AAS Nova Astronomical Society of the portal, the journalist and editor Susanna Kohlero gave a summary of their main points. Initially, we will let the basic information short.

What is it?

The story began in October 2017. The Haleakalā Theater telescope in the Maui Hawaiian island took a wild body that was away from the sun. The nearest one, about a quarter of Earth-Sun speed, was still in the first decade of September. At first sight, nothing is amazing, maybe planning. However, the reconstruction of the route revealed that it reached another star.

Initially we also know your body. Although the tears have been thinking about it in a long time, especially with comets. In the formal distribution of spaceships that were found again, the letter that I introduced was as an inter-state (inter-state) shortcut. 1I / 2017 Group was nominated to honor the location found & Oumuamu, which is around Hawaii & # 39; messenger from the old weather &

The strange shape, the strange movement

Clear clear changes to see the level of clarity of Oumuamu to be able to rotate; body with an unusual shape. He's like to get involved in the way. Initially, the ratio was considered to be a length of 10: 1, at least 5: 1 at present. The length is considered at hundreds of meters, width to ten and up to ten meters. Your body may be very much covered.

The red and dark color associated with the surface are coming from a & # 39; creating stones, metal, azda by adding organic and ice "black" to it. That would give evidence to the planet. However, the movement of the body can not be explained but in particular. It was faster than the sun. Well, the acceleration value was the responsibility of the minute & # 39; Oumuamu from the sun.

Comet? scarce

This would indicate a flowing effect made by a & # 39; stealing a steamed gas after the warming of frozen substances on or near a & # 39; body with sunlight at sunset and after that. In that case, we needed to & # 39; address the heart of her.

Things are harder. Roman Rafikov from Cambridge University (United Kingdom) and the Princeton High School Institute, New Jersey, noted that Oumuamu had no gas solution, uncomfortable (main cheese shells), without dusty or gaseous tail. If they can not be visible, they would accelerating movements. To the extent that the body would eliminate the influence of the important forces through the passage through the solar system.

Where did it come from?

Due to the abolition of the Oumuamua Sprava & # 39; lost. We can not tell where this body came. His position is not based on any expert star. This valuation of body movement has been helped.

Out-of-pay out-of-date not only has a strict impact. Including unimportant acceleration with the 7 million DR2 database of BB2 based on European satellite measurement Gaia, first promising promise to be taken in this regard.

The artistic vision of the Oumuamu barley-shaped body, seen from another angle, is slightly out of place.

Dozens of star homes

Coryn Bailer-Jones of the Max Planck Institute for Music Studies in Heidelberg, Germany, has been four starred observations. The most common are the HBO 3757 red, around which the body has been around 1 million years ago, with the star HD 292249 around around 3.8 million years.

But it does not belong only if it's & # 39; Oumuamua always moves the same way. This may not be true. Coryna Bailera-Jones said that every million years on Oumuamua has been achieved especially with about 20 stars and brown dwarfs (bodies of Jupiter stars and planes) when traveling within 3.26 years of light.

And now for science fiction …

Abraham Loeb of the Harvard-Smithsonian astrophysics center in Cambridge (Massachusetts, SA) has a bit of insight into complex mindset. He even did not even even put it at Oumuamu. With co-worker, Shmuel Bialym said: the acceleration of this group can be explained when it is a "sailing sailing" type.

That is, a group that has a & # 39; influencing radical pressure. And even even a format can even be # 39; Oumuamu's more difficult than we have mentioned. In particular: it would be very thin. In a large area situation, the sunrise would give such a weight that he would explain the acceleration. According to authors, of opinion, a large body, but a thin, could be a & # 39; suffering from inter-state flight too.

The couples do not say that & # 39; Oumuamu & # 39; a sunny sailing sailing. Forms of this type also occur naturally in an inter-state subject. But the original timber of this body does not disagree. It may be a type of technical waste, ethical vitality.

… and really back

& # 39; Oumuamu is still a mystery. Apparently, she will still. During the passage through the solar system, it could not be & # 39; get her thoughts clear enough. In particular, we did not get it, and we did not; We can even do it, as we still have nothing. They return to the stars.

Although the case is a & # 39; mentions the science fiction novel by Arthur Clark's Meeting with Rama, the essential means of preaching "living at the ground". Without further evidence, it is still necessary to come to a conclusion that it was a natural group that we did not meet before. At least I do not know.

Spam memory

But the whole thing is a great reminder. In March 1989, Planet 4581, aged a hundred years ago, was the age of Asclepius, a point where the Land was only six hours before. The disaster would release a power of 600 meters TNT. But we got out of the plan nine days after the best way of doing it; our planet. She could not expect us to "fall on my head".

Oumuamua, which was similarly resembled (even more than a month) after going to & # 39; travel through the solar system, reminding us that we do not need to know what is going on; going on in our important home. Fewer we can have an effective effect. It is outside our control.

In a weak state of cosmetic technological infrastructure, due to the fact that the development has been in a position; Unfortunately, we still have a huge release of the world. Which is the form of a natural body, a striking course with Earth, or stranger with an unidentified mission.

Romain Rafik's study was published in the Astrophysical Journal Letters. Coryna Bailera-Jones has published his research in The Astronomical Journal. Finally, Shmuel Bialy and Abraham Loeb conducted their study in the ArXiv Internet Archive, according to Astrophysical Journal Spelling.
