Poyasnenie: Krasochnaya faza planetarnoi tumannosti dovol'no bystrotechna v zhizni solncepodobnoi zvezdy. Mozhno skazat', chto po kosmicheskim merkam zvezda i morgnut'-to ne uspevaet, kak ee vneshnie sloi sbrasyvayutsya, formiruya rasshiryayushuyusya emissionnuyu tumannost'. Tumannost' sohranyaetsya vsego lish' okolo 10 tysyach let. Sravnite eto s 10 milliardami let, skol'ko zhivet takaya zvezda. Planetarnye tumannosti horosho znakomy ne tol'ko professional'nym astronomam, no i lyubitelyam. Tem ne menee oni vse eshe tayat v sebe nekotorye syurprizy. Naprimer, v prekrasnoi tumannosti NGC 6826, izvestnoi takzhe pod nazvaniem Migayushii Glaz, s dvuh storon vidny zagadochnye krasnye LETChIKI (fliers). Oni horosho zametny na snimke, poluchennom kosmicheskim teleskopom im. Habbla. Esli oni tozhe udalyayutsya ot central'noi zvezdy, to pochemu zhe golovnaya udarnaya volna raspolozhena u nih ne s toi storony!?
