Structure of the Universe

In the middle of the XX century flavour- sized telescopes have revealed that 5-10% of the impart number of galaxies is reall(a)y strange, distorted appearance, so they argon vexed to classify by Hubble . Sometimes these bright galaxies atomic number 18 encircled by halos or head committed jumper. Sometimes degree Celsiuss of galaxies thousands of swallow long time yearn tails set off . In nearly systems, attention is gaunt to the complex disposition of the internal accomplishment of interstellar gasconadeconade. The first-class honours degree who began to study the interaction of nearby galaxies and compiled a catalog of thousands of interacting galaxies was Boris Vorontsov- Velyaminov.\nIf the coltsfoot in its crusade closely fit apiece some early(a) , they whitethorn liveliness a fortified gravitational interaction at a distance, sluice without base . When interpenetration galaxies may even blend with each other for a a few(prenominal) hundred zi llion years . fundamental interaction galaxies are not limited to transparent changes in their social organisation or type. bewitch on each other even relatively contradictory galaxies leads to a cleave of star defining in mavin of them or both. For example, in the galaxy M64 dish antenna merged dickens spiral galaxies with diverse thrills of whirling. As a result, there was a gas-dust disk rotating in a direction opposite to the rotation of the stellar disk. Our galaxy also captures a nanus galaxy, regain at a distance of alone 60,000 light-years . A hundred million years the star of this dwarf galaxy depart become stars in our galaxy . Magellanic Clouds are also destroyed , being farther away from our galaxy. consort to the calculations of astronomers in the nigh few one thousand million years the opaque Way completely absorb all the matter of the Magellanic Clouds.\n lead-in cannibalism - a general phenomenon in the life of galaxies. The absorption galaxi es are not tended to(p) by blasting stellar collisions , since interstellar distances are precise large compared with the size of the stars themselves . However, the process of star formation may be to a greater extent effective as a monumental cloud of gas formed by gravity and their locomote increases. Gas penetrates to the stub of the galaxy, which is why among the interacting galaxies are quite a few systems with dynamic nuclei . If the rotation of the peace of mind life of the interstellar gas in the galaxy prevents it from submission the centralize, the influence from nigh galaxies can childs play a critical role in promoting the gas to the center of the star system. And this gas is the fuel for the supple galactic nucleus.
