Thanks to centuries of observations, astronomers have succeeded in better describing our solar system. But today, thanks to modeling and supercols, they can move forward. And show the structures they did not expect.
And the cloud. Its existence on the borders of our solar system, somewhere between 2,000 and more than 100,000 astronomical units (AU) of our star – as much times as the sun’s land is the first time in the 1950s. Is A AstronomyAstronomy The same name is Dutch. And this cloud of Orwort will store the doubles that will occasionally meet us.
Astronomers have never had the opportunity to directly hide the overt, cloud and thousands of items. Wigger 1 Investigation will not reach it for 300 years! But what researchers know is to indicate that it has a spherical form. Like a shell around our solar system. But from researchers Southwest Research Institute (United States) and the American Museum of Natural History are no longer fully convinced. They explain their doubts in a research published Archeo And who have not yet been reviewed by colleagues.
Modeling to display the structure of the overtaking cloud
Remember that after the birth of the planets of our solar system, and Wort Cloud started training. From the remains who did not serve and those who were far beyond thatOrbitOrbit Injured PlutinPlutin. The internal part of the overtaking cloud is between 2,000 to 5,000 AU. The outer edge, between 10,000 to 100,000. At such a distance, relatively small things that are these are far from our best devices.
Therefore, to know more, the astronomer is the best weapon of astronomy ModelingModeling. US researchers focus on internal and t -cloud. And they should not only understand its effects Gravity forcesGravity forces Of all the planets of the solar system on this structure, but also the effects of gravity forces through the rest of our sky. Especially by our Galaxy centerGalaxy center Where most of it M’sM’s.
A spiral galaxy -shaped cloud
Astronomers know that there is a trend, of a kind of «WaveWave Galaxy ”Which affects the positioning of items in the large -scale overturry cloud. News MisconductMisconduct For example, when this maize is for example, for example our solar system is forced to enter the interior of the solar system. This dynamic is especially complicated. Thus, it would be necessary to help researchers SupercolutersSupercoluters PlyadisPlyadis That NasaNasa – To overcome it – the most powerful in the world. And what his model at least said was unexpected. An internal cloud is not like a circle, but as a disk of about 15,000 Au diameter, moves by about 30 degrees compared to the planet project. And above all, with two spiral arms that show it almost like A GalaxyGalaxy.
Researchers unfortunately believe that it will be extremely difficult to create a picture of these two Arms spiral. This will really require direct observation of a large number of items in this area of place, or the radiation of these items will be eliminated from the background and well -known sources. None of these two methods currently have dedicated resources. With their results, astronomers now emphasize where the doubles come from, how our solar system is developed and the effects of and the effects of the and the cloud on our cosmic area, in this regard. Starting the plan may be a matter of wisdom.
