Poyasnenie: Kak vyglyadyat polyarnye siyaniya iz kosmosa? S poverhnosti Zemli predstavlyaetsya, chto polyarnye siyaniya voznikayut nad oblakami. Chasto oni predstavlyayut soboi nezabyvaemoe zrelishe. Na vysote vozniknoveniya polyarnyh siyanii vrashaetsya po orbite Mezhdunarodnaya kosmicheskaya stanciya (MKS). Inogda ona proletaet nad nimi, a inogda neposredstvenno cherez nih. Potoki elektronov i protonov v polyarnyh siyaniyah dovol'no slabye i ne predstavlyayut opasnosti dlya MKS, tak zhe kak oblaka ne predstavlyayut opasnosti dlya samoletov. Don Pettit, rabotayushii v sostave MKS kosmonavtom-issledovatelem (oficer po nauke, Science Officer), poluchil snimok zelenogo polyarnogo siyaniya, obrabotannyi v cifrovom rezhime. D-r Petit rasskazyvaet, chto s orbity MKS polyarnye siyaniya vyglyadyat kak gigantskie zelenye koposhashiesya ameby. Na snimke viden krater Manikuagan (severnaya Kanada), obrazovavshiisya v rezul'tate stolknoveniya nebesnogo tela s poverhnost'yu Zemli.
