Zametil ocherednuyu zakonomernost'.

Rukava.

Esli galaktika sostoit iz yavno vidimyh dvuh rukavov,
to eto rukava ot sliyaniya dvuh galaktik.

Galaktiki sblizhayutsya.

Dannaya galaktika samaya interesnaya iz vseh, u etoi galaktiki proizoshlo sliyanie dvuh
galaktik, chto povleklo za soboi rezkoe rassloenie zvezd, i u centra galaktiki zvezdy
nachali bystro samo-sblizhat'sya i rezko uvelichilas' temperatura v centre, i estestvenno
rezko snizilas' plotnost' efira, i zvezdy v centre ne mogut obespechit' nuzhnogo
davleniya vnutri sebya chtoby uderzhat' zvezdu efira ot togo chtoby chasticy Aleksandra,
ne nachali prevrashat'sya v chasticy efira. Pri vosstanovlenii chastic Aleksandra, k etim chasticam
prisoedinyaetsya energiya, i chastica uvelichivaet ob'em v milliard i bolee raz, i prevrashaetsya
v chasticu efira (chastica efira v milliard raz men'she chasticy (uslovnoi chasticy) vozduha),
pri etom process na nekotoroe vremya stanovitsya neobratimym. Pri blizko raspolozhennyh sosednih
zvezdah, rezko vosstanovivshiisya efir u sosednih zvezd delaet bokovoi rezkii gidravlicheskii udar pri etom
mozhet sdut' vneshnyuyu obolochku, i zvezda efira ostanetsya pozadi a obolochka iz materii sletit.
I pervonachal'noe vosstanovlenie efira nabiraet lavinoobraznyi vid, chto v rezul'tate tak daleko
davleniem efira razbrosaet zvezdy, chto bol'shinstvo zvezd nikogda ne soberutsya v odnu galaktiku,
oni pri ostyvanii sformiruyut mnogo nebol'shih galaktik na bol'shom udalenii drug ot druga.

Osnovnaya dostoprimechatel'nost' etoi galaktiki - eto samaya dinamichnaya chast' zhizni galaktiki.

To chto hotyat sdelat' katalog - to eto konechno gde-to logichno, no ne sovsem pravil'no, pravil'no u analogichnyh
galaktik vesti nepreryvnuyu videozapis' v teleskop.

No uchityvaya v kakom kamennom veke zhivem chto opredelyaetsya kolichestvom teleskopov v kosmose na million ,
etot vopros budet vryad-li kogda reshen v obozrimom budushem.
