Poyasnenie: Nekotorye spiral'nye galaktiki vidny pochti tochno sboku. Bol'shinstvo yarkih zvezd v spiral'nyh galaktikah obrashayutsya vokrug centra v diske, i esli smotret' sboku, etot disk mozhet vyglyadet' dovol'no tonkim. Nekotorye spiral'nye galaktiki vyglyadyat dazhe ton'she, chem NGC 3717, kotoraya vse-taki ne vidna tochno sboku. V spiral'nyh galaktikah formiruyutsya diski, potomu chto gaz, iz kotorogo oni formiruyutsya, ispytyvaet vnutrennie stolknoveniya i ostyvaet, padaya vnutr'. Po toi zhe prichine planety obrashayutsya v diskah. Eto izobrazhenie bylo polucheno kosmicheskim teleskopom im.Habbla, na nem viden okrashennyi v svetlye ottenki central'nyi baldzh, sostoyashii iz bolee staryh zvezd. Pered nim nahodyatsya temno-korichnevye volokna pyli. Razmer NGC 3717 – okolo 100 tysyach svetovyh let, ona nahoditsya na rasstoyanii v 60 millionov svetovyh let v sozvezdii Gidry.
