Poyasnenie: NGC 2903 yavlyaetsya spiral'noi galaktikoi, pohozhei na nash Mlechnyi Put'. Shodstvo sostoit v razmerah i nalichii central'noi peremychki. Sushestvennoe razlichie mezhdu galaktikami zaklyuchaetsya v nalichii zagadochnyh goryachih pyaten v yadre NGC 2903. Pri detal'nom analize privedennogo izobrazheniya i analogichnyh snimkov, poluchennyh na Kosmicheskom teleskope Habbl eti goryachie pyatna okazalis' molodymi sharovymi skopleniyami v otlichie ot staryh sharovyh skoplenii, nablyudaemyh v Galaktike. Dal'neishie issledovaniya pokazali, chto v nastoyashee vremya naibolee intensivnoe zvezdoobrazovanie proishodit v kol'cevoi okrestnosti yadra NGC 2903 shirinoi v 2000 svetovyh let. Astronomy predpolagayut, chto gravitaciya v central'noi peremychke uskoryaet zvezdoobrazovanie v kol'ce. NGC 2903 nahoditsya na rasstoyanii v 25 millionov svetovyh let i vidna v nebol'shoi teleskop v sozvezdii L'va.
