4631
– eto spiral'naya galaktika v severnom sozvezdii
Gonchih Psov,
udalennaya ot nas vsego na 25 millionov svetovyh let.
Ona vidna s rebra i po razmeru pohozha na nash Mlechnyi Put'.
Nekotorym eta galaktika s ee iskazhennoi klinoobraznoi formoi
kazhetsya pohozhei na kosmicheskuyu seledku, a drugim – na kita,
i ee chasto nazyvayut galaktikoi Kit.
Malen'kaya i udivitel'no yarkaya ellipticheskaya galaktika
NGC 4627 – sputnik bol'shoi galaktiki – vidna pryamo nad
zheltovatym, bogatym pyl'yu yadrom NGC 4631.
Na snimke vidny takzhe nedavno
obnaruzhennye
slabye karlikovye galaktiki v galo NGC 4631.
Slabye protyazhennye detali vyshe i nizhe NGC 4631 yavlyayutsya prilivnymi potokami zvezd.
Zvezdnye potoki – eto ostatki karlikovoi galaktiki-sputnika, razrushennoi
povtoryayushimisya
sblizheniyami s galaktikoi Kit, kotorye nachalis' okolo 3.5 milliardov let
nazad.
Dazhe v blizkih galaktikah
prisutstvie prilivnyh zvezdnyh potokov predskazyvaetsya kosmologicheskimi modelyami formirovaniya
galaktik, vklyuchaya
formirovanie nashego Mlechnogo Puti.
