Science Review 1/12 | Univer / O
Happy New Year! The end of last year, the Science Week did not stay longer the weekly schedule, so in honor of the new year, Science Week is changed tiedekatsaukseksi. New year starts on astronomy and the first review processes held in January, the American Astronomical Society winter meeting of the issue. brabantia food warmer There will be further studies on the formation of foolproof hit product this year exoplanets and not forgetting the dark matter gamma rays. And let 's get going ... a network of dark matter
We can not see it, we can feel it, and we can not react with it, but the dark matter is one of the pillars of the universe. The first hints to us the existence of the invisible substance obtained in the 1970s spiraaligalaksihavainnoista, explaining that pyörimisprofiilin dark matter first proposed. Since then, scientists have shown that dark matter dominates brabantia food warmer the amount of substance in the universe five times compared to the share of the available brabantia food warmer space, the atoms consist of material. Simulations brabantia food warmer have shown that the universe is organized as a reticulated structure, with nodes of dark matter has accumulated concentrations of visible matter, galaxy clusters, but so far scientists have not been able to demonstrate this on the basis of the findings. brabantia food warmer Now an international research team using the Canada-France-Hawaii Telescope has been able to detect large-scale mesh-like structure brabantia food warmer of dark matter. But how is that possible, when the dark matter is impossible to see? The solution is to use a self dark matter detection tool. The researchers explored how the foreground galaxy clusters are located kaareuttavat space, and at the same time distorting the set of galaxies behind the light, the so-called action. gravitational lens. The researchers found in the background galaxies apparent curvature and fell just how massive foreground galaxy is a set must be so observed curvature was able to reproduce the aid of a computer model. This makes it possible to assess the galaxy in a number of the actual mass of dark matter, including. Accordingly, brabantia food warmer the amount of dark matter obtained by subtracting the mass of the total mass of the visible matter, ie stars and galaxies, which in turn can be estimated on the basis of the brightness of the galaxy population. The results are based on observations made during the five years of the ten million galaxies, which allows yo. dark matter brabantia food warmer map were formed. Map is further confirmation of the fact that the structure of the universe is composed of dense nodes, the massive galaxy clusters, connected by thin filaments, which are surrounded by blank areas.
Gravitational lensing can be used to explore the more than dark matter, namely the planets. In the same way as galaxy clusters distorts the back of a number of galaxies in the light, so a single asterisk (and orbiting planets) in the Milky Way can distort the star behind it in the light. brabantia food warmer Two stars must be located exactly in the same line as seen from Earth, so that the foreground star and planet aihettama change brabantia food warmer in brightness is noticeable. The probability that two stars happens to be located in this way is therefore very small. Fortunately, the Milky Way galaxy has no shortage of stars, so the solution is to detect the very many different stars and hope for the best. Thus, astronomers have discovered more of a million stars every night for six years. All in all, caused by the planet's Gravitational lensing phenomena was observed brabantia food warmer in all of three pieces. The amount may not sound like much, but in fact it is surprisingly a lot considering how rare the phenomenon is. Gravitaatiolinssimenetelmä method is relatively sensitive to the mass of the planet and its orbit determination. It can be used to detect planets with a mass of from five to ten mass of the Earth until the mass of Jupiter, and which are located 0.5-10 AU (1 AU = the average distance from the Sun, Earth) from the host star. Previous studies have shown that the masses of planets around stars are distributed according to a power law decreasing brabantia food warmer the heavier planets come. In other words, topping Ground massaisten, brabantia food warmer the number of planets in our galaxy is larger than the planets, such as Jupiter's heavy. Utilizing this information, the researchers were able to estimate the number of different massaisten planets in the Milky Way based on new gravitaatiolinssihavaintoihin exoplanets. We do not, of course, is no reason to doubt that those findings were somehow special quality, but it is a random sample of stars in the Milky Way, so on the basis of observations made of the number of planets in the generalization is quite valid. What's the result, then, strictly speaking, is it? Researchers brabantia food warmer estimate brabantia food warmer that on average around each star is 1.6 (+ 0.72 / -0.89) planet. This does not mean that around each star would be a planet. After all, our solar system eight planets already. But to start
