Poyasnenie:
Kak poluchilos', chto spiral'naya galaktika ESO510-13 prinyala takuyu formu? Diski bol'shinstva spiral'nyh galaktik tonkie
i ploskie i, estestvenno, ne predstavlyayut soboi sploshnoe telo. Diski galaktik yavlyayutsya svobodnoi sistemoi milliardov zvezd i diffuznogo gaza, kotorye obrashayutsya nezavisimo
vokrug galakticheskogo centra pod deistviem gravitacionnogo prityazheniya. Schitaetsya, chto ploskii disk obrazuetsya v rezul'tate neuprugogo stolknoveniya
krupnyh gazovyh oblakov na nachal'noi stadii evolyucii galaktiki . Iskrivlennye
zhe diski vstrechayutsya dostatochno chasto vo Vselennoi. Astronomy podozrevayut, chto dazhe Mlechnyi Put' imeet
slegka iskrivlennyi disk . Prichina iskrivleniya diskov spiral'nyh galaktik zaklyuchaetsya v tom, chto galaktiki vzaimodeistvuyut
mezhdu soboi, a v nekotoryh sluchai dazhe slivayutsya. Na segodnyashnei
kartinke izobrazhena galaktika ESO510-13, kotoraya nahoditsya na rasstoyanii 150 millionov svetovyh let ot nas i v poperechnike sostavlyaet sto tysyach svetovyh let.
