Polyarnoe siyanie i voshod Solnca
Avtory i prava: NASA, Mezhdunarodnaya kosmicheskaya stanciya, Riki Arnol'd
Perevod: D.Yu.Cvetkov
Poyasnenie: S Mezhdunarodnoi kosmicheskoi stancii (MKS) lyubovat'sya polyarnymi siyaniyami mozhno tol'ko do voshoda Solnca, posle etogo Zemlya stanovitsya slishkom yarkoi. Odnako MKS obrashaetsya vokrug Zemli bystro, i eto oznachaet, chto posle zakata do sleduyushego voshoda Solnca ostaetsya men'she 47 minut. Na etoi fotografii zelenoe polyarnoe siyanie vidno pod MKS i vverhu sprava na gorizonte, a rassvet priblizhaetsya s verhnego levogo ugla. Nablyudeniya polyarnyh siyanii iz kosmosa mogut gipnotizirovat', ih izmenyayushiesya formy mozhno sravnit' s ogromnoi zelenoi ameboi. Polyarnye siyaniya voznikayut, kogda elektrony i protony s vysokoi energiei, vybrasyvaemye Solncem, zahvatyvayutsya zemnym magnitnym polem i letyat k Zemle tak bystro, chto vyzyvayut svechenie atomov i molekul v atmosfere. Orbita MKS prohodit pochti na toi vysote, gde voznikayut polyarnye siyaniya. Stanciya mnogo raz proletaet cherez razrezhennye verhnie sloi polyarnyh siyanii, odnako eto nikak ne vredit astronavtam i ne izmenyaet formu polyarnogo siyaniya.
