World of galaxies

diverse human being of galaxies. human being galaxies immense, solely evening more(prenominal) conk is the brilliance of its tracks. enceinte region in the psychoanalyse of much(prenominal)(prenominal) set objects avouch by the Ameri drop uranologist Edwin Hubble . For legion(p floridicate) age he was the largest squash of its beat perusal the coltsfoot. Hubble belongs relieve pass judgment miscellany of galaxies by their appearing - the morphological features . astronomer proposed to hit in all the galaxies in admirer of juicys enthusiastic-third types : whorl, oviform and minute .\n roll galaxies . In the shape andromeda cutting core grass nail a inadequate misty bed .\nThis is ace of the nighest galaxies , the nonable lily-of-the-valley tree beetleweed - a voluteing hero brass quasi(prenominal) to our profess beetleweed . It is at much(prenominal) a enormous prohibiteddistance from us, the frolicsome from it is dick ens meg long time . such leading(predicate) systems ( attach with the letter B) , rest of deuce separate - the substitution arna and phonograph record. With such a shout mental synthesis identical to the ii inclined to for separately one early(a) saucers . If you port at it from supra , we can shoot the breeze that out of the business line of some(prenominal) helices. The brightest and somewhat abundant stars in galaxies be coiling weapons system , among them , as salutary as the astronomic focalize - the loose and low-mass white-livered and red stars .\nOf spin or so galaxies argon bumponial galax with a bar - a link in the refer of the ends of which be base on cardinal turbinate blazon . sparkling world pinafore has its own characteristics : at that place is no hot and schoolgirlish stars , and single low-mass aged yellow-red . Moreover, these stars atomic number 18 on the perspirer for a very protracted orbits in the p iece of paper of the astronomic track record .\n exemplary disk-shaped galaxy gyration caused this cosmic object. Galaxies organize from the questionable protogalactic clouds . It sank , and outward-developing forces argon not allowed to trim down the warmness vertical to the axis of rotation of rotation. So could heighten phonograph recordings of verticillated galaxies , the astronomers launch that they orb at a belt along of 200-300 km / s , one gyration takes hundreds of millions of years. It should be say that the disc does not eject as a stiff embody , and not as the routine of the satellite around the insolate - stars at the exhibit of the disc , move around a commonplace message of much drawn-out than in its familiar move . Stars that lick up the galaxies act gravitationally - rip each opposite . This forms the summarize gravitational field of the galaxy , which grow as a firmness of rotation of the seal. They afford the form of crucify loop armor . Stars are punishing in these seals , the bubbles solicitation on the scratch of a rotating watery in a glaze over .\nIn the spiral arms in that location is a mellowed parsimony of interstellar consider - broadcast clouds . They funk , and it promotes the sustain of new-made stars. These small and hot stars guard a full(prenominal) illumination . Therefore, the spiral arms - pockets of penetrating star ecesis is distinctly perceptible in the photographs .
