Zelenyi luch nad Italiei
Avtory i prava: Danilo Pivato (Beyond the Moon)
Perevod: D.Yu.Cvetkov
Poyasnenie: Kak Solnce mozhet stat' zelenym? Bylo dokazano, chto kratkovremennyi zelenyi luch nad voshodyashim ili zahodyashim Solncem deistvitel'no voznikaet, hotya nablyudat' ego ochen' trudno. Prichina etogo yavleniya - otklonenie solnechnogo sveta v atmosfere, ili refrakciya. Kak slabaya prizma, zemnaya atmosfera razlagaet belyi solnechnyi svet na cveta, prichem krasnyi cvet prelomlyaetsya na men'shie, a zelenyi i sinii - na bol'shie ugly. Pri yasnom nebe zelenyi luch pryamo nad kraem Solnca mozhno inogda uvidet' na neskol'ko sekund, kogda Solnce blizko k dalekomu gorizontu. Vse zhe astrofotografu Danilo Pivato udalos' zapechatlet' zelenyi luch, snyav etot effektnyi fil'm s vershiny gory Autore (vysota 1850 metrov) v Italii. Interval mezhdu kadrami izmenyaetsya: v nachale on bol'she minuty, a kogda poyavlyaetsya zelenyi luch, on sostavlyaet primerno sekundu.
