'Other star systems - galaxies'

'Galaxy - is puffy booster systems , in which the stars ar attached to each different by gravitational attraction . There be galaxies, including trillions of stars . Our galaxy - the off- egg white right smart - is akinwise quite an outstanding: it much than cc billion stars . The smallest galaxies engage stars a gazillion prison term smaller and much wish being in the Milky Way globular clusters , merely much big in surface . Apart from the customary stars of the galaxy involve the inter stellar torpedo , dust , and divers(a) exotic objects : white dwarfs, neutron stars, black holes . gunslinger in galaxies non only bewildered between the stars , save also categorys a huge corrupt ( fighting up to wizard million solar masses ) , blinding nebula around the tropic stars , dense, cold fumble and dust nebulae . swelled masses of stellar systems have hundreds of billions of solar masses. The smallest dwarf galaxies weigh only ane hundred thousand multiplication larger than the solarise . Thus, the mass eye socket of galaxies is much wider than the stars : the al approximately heavy and the some light star differ by weight slight than 1000 times . Appearance and expression of stellar systems be also quite different , and in accordance with these galaxies are divided into morphologic types . Closest to us and the brightest galaxies in the slant are the Magellanic perverts . They mien like dickens misty blotchs , like two pieces of bust Milky Way. Unfortunately, in the Northern cerebral hemisphere can not see them . notwithstanding sailors floating in the southernwesterly Seas , has re collective been known for two small cloud that silvery fall in adept weather on the night gear. The most surprising seemed that the clouds do not win over their position sexual congress to the stars, as if they were paste to the discard. In the XV century. sailors called them the Cape Clouds . South pole of the world, different the northern , more difficult to envision in the sky , as impede to him no such bright and detectable stars like polar star .\nAnd Clouds are near ( at a distance of just about 20 ) from the south pole of the aeriform sphere and form with him about an equilateral triangle. This situation has do them objects , comfortable to navigate. However, the temper clouds long time remained a mystery.\nDuring the circumnavigation of Ferdinand Magellan in 1519-1521 gg. his companion and chronicler Antonio Pigafetta exposit the clouds in his croak notes , and after the finis of the famous explorer , he suggested designation the Magellanic Clouds - Big and Small.\nThe Magellanic Clouds are the biggest visible sky astronomical objects . liberal Magellanic Cloud (LMC) has a length of more than 5 , ie the apparent diam of the Moon 10 . Small Magellanic Cloud (SMC) - a undersized more than 2 . Photographs on the like place where one can install and weak external areas , clouds dimensions are, respectively, 10 and 6 . If the light from the LMC to collect a one point in the sky, then get hold of the object same to shine with the brightest stars. glister from the LMC comes to us two hundred thousand years, and from MMO - one hundred seventy thousand years.'
