Poyasnenie: Na snimke pokazan ostatok sverhnovoi, kotoryi nazyvaetsya Petlya Lebedya. Snimok poluchen v noyabre 1997 goda s pomosh'yu planetarnoi kamery-2 s shirokim polem na bortu kosmicheskogo teleskopa "Habbl". My vidim s rebra nebol'shuyu oblast' ogromnoi udarnoi volny, dvizhusheisya (na snimke) vverh so skorost'yu 170 km/s. Ee svechenie obuslovleno izlucheniem vozbuzhdennyh atomov vodorodnogo gaza. Eto zamechatel'noe izobrazhenie - ne tol'ko ocherednaya krasivaya kartinka. S ego pomosh'yu astronomy poluchili vazhnye nauchnye rezul'taty. V 1999 godu ono bylo ispol'zovano dlya utochneniya rasstoyaniya do etogo klassicheskogo ostatka sverhnovoi i ego vozrasta (v storonu umen'sheniya). Teper' schitaetsya, chto Petlya v Lebede nahoditsya na rasstoyanii vsego lish' 1 440 svetovyh let ot nas i obrazovalas' 5-10 tysyach let nazad.
