Kan'on Podkova v antisumerechnyh luchah
Avtory i prava: Peggy Peterson
Poyasnenie: Chto za yavlenie nablyudaetsya v nebe nad gorizontom? Kartina na pervyi vzglyad kazhetsya neestestvennoi, no na samom dele eto vpolne obychnyi zahod Solnca pri udachnom raspolozhenii oblakov. Na risunke pokazany antisumerechnye luchi. Chtoby ponyat' ih proishozhdenie, predstav'te sebe obychnye sumerechnye luchi, kotorye poyavlyayutsya vsyakii raz, kogda solnechnyi svet rasseivaetsya oblakami. Hotya solnechnye luchi rasprostranyayutsya vdol' pryamyh linii, eti linii proektiruyutsya na nebesnuyu sferu v vide bol'shih krugov. Sledovatel'no, budet kazat'sya, chto sumerechnye luchi ot zahodyashego (ili voshodyashego) Solnca shodyatsya v protivopolozhnoi storone neba. V anti-solnechnoi tochke, na uglovom rasstoyanii 180 gradusov ot Solnca, oni nazyvayutsya antisumerechnymi luchami. Nablyudaya posle obeda zahod Solnca vozle kan'ona Podkova (shtat Yuta, SShA), fotograf uvidel eshe bolee vpechatlyayushee zrelishe v protivopolozhnom napravlenii nad samim kan'onom - antisumerechnye luchi.
