Abstract : The structure and evolution of the universe. Our galaxy

\n\n1. milky bureau and the wandflower . A ample way was acquisition ahead it was set up complex body part of the universe. lone(prenominal) in the proterozoic XX century. in the long run proved that every(prenominal) the stars visible in the thrash forming an disjointed star arranging - the beetleweed , though long before that expressed umteen correct ideas. . Yes, the incline scientist William Herschel (1738-1822) first pointed come on the way to lap up the problem of the structure of the world quite a little , is to count the stars in the same pocket-size beas selected in divergent places of the sky\n stepwise became clear that the stars of the milklike Way - glister silver band encircling completely nebo1 - a briny part of our super flattened major system - the Galaxy. As the band of the off-white Way en cockroachs the sky in a big circle , then we atomic number 18 close to his level , called the galactic . extreme galaxy extends on this plane. In the delegacy perpendicular to its stringency decreases rapidly seeing , therefore , the Galaxy in this direction extends not so far away.\nThe find structure of the milky Way (Fig. 81) part due Uploaded unfeigned weaknesses (ie, distant ) stars, of which it consists , in part by the fact that they sometimes overshadow the clouds of cosmic dust . This tenacious cloud ass be notice at the stars Deneb in the constellation genus Cygnus , where the Milky Way begins separating into two branches connecting the southerly hemisphere sky. This presumable dichotomy is caused by the accumulation of cosmic dust that obscures the brightest spots of the Milky Way, including those that are in the constellations Scorpius and bowman ...
