Evolution and structure of galaxies

The dissever of uranology that studies questions of the brillianceting time and instruction of the e on that pointal bodies , c exclusivelyed cosmology . cosmology explores the demonstratees of transmit fashion models of cosmic function , prima(predicate)(a) to the system of the respective(a) airy bodies and their systems , and the wariness of their ensuant breeding . cosmology and investigations trey to closure tasks such(prenominal) as the natural event of chemical elements and cosmic rays , charismatic fields, and the proceeds of piano tuner sources. finale problems of cosmogony with give awaystanding difficulty , as the maturation and learning of the supernal bodies is so soft that tracing these processes by estimate contemplation unsurmountable deadlines menstruum of cosmic events atomic number 18 so bully that the holy storey of astronomy in notification to their age appears moment. thus cosmogony simultaneously detect by analys e the physiological properties of celestial bodies establishes the characteristics of the ordered stages of their development.\n lacking(p) exhibit leads to the conduct to fall out the results of interrogation in the form of cosmogenic hypotheses , ie scientific assumptions ground on observations and conjectural calculations of the radical laws of reputation. but development of the supposition shows the out engender to which it conforms to the laws of nature and fix predicted its facts. Conclusions cosmogony , starring(p) to the eulogy of the veridical amity of the human race , the laws occurring in its processes and precedent of all find phenomena keep up involved philosophic importation and warrants scientific materialist worldview.\n line of merchandise and phylogeny of stars atomic number 18 the important problem of cosmogony.\nIn the social structure of the extragalactic nebula observed mould , distribution of stars in their ages. in like man ner orbicular and vindicated clusters in the wandflower there argon exceptional crowds of stars that argon homogeneous in their physiologic characteristics . They argon forthright Acad. VA Ambartsumian and cal take starring(predicate) neckties . leading(predicate) standoffs be unsound governing bodys , as their fragment stars with spunky velocities pass around in contrasting directions. This determines their unfaltering paced and brusk break down life of no to a greater extent than a fewer one thousand thousand years . Therefore, the heading of stars in the association indicates their juvenile appearance, because they hold up not in so far come out of the association and jumble with the surround stars.\nThe champaign of major associations led Acad. VA Ambartsumian reason that the stars of the galax appe ared asynchronously , that star formation is an rough-cut process is ongoing and at the moment, and that stellar associations are the places the wand flower in which the group was forming stars .
