Seguramente te ha pasado: vas manejando o caminando, levantas la vista y el cielo te regala un espect\u00e1culo de colores que parece sacado de una pel\u00edcula. Pero, \u00bfqui\u00e9n decide cu\u00e1ndo toca azul y cu\u00e1ndo toca un naranja intenso? Aunque parezca una obra de arte, la respuesta est\u00e1 en una batalla cient\u00edfica que ocurre a kil\u00f3metros sobre nuestras cabezas.<\/p>\n\n\n\n

El secreto est\u00e1 en la luz<\/h3>\n\n\n\n

Todo comienza con la luz del sol. Aunque la vemos blanca, en realidad es un \u00abc\u00f3ctel\u00bb de todos los colores del arco\u00edris. Cuando esta luz choca con la atm\u00f3sfera de la Tierra, las mol\u00e9culas de aire act\u00faan como peque\u00f1os obst\u00e1culos que dispersan los colores.<\/p>\n\n\n\n

\u00bfPor qu\u00e9 azul?<\/strong> Durante el d\u00eda, el sol est\u00e1 sobre nosotros y la luz azul (que viaja en ondas cortas) choca y se esparce por todo el cielo. Por eso, al mirar hacia arriba, vemos esa c\u00fapula azulada.<\/p>\n\n\n\n

El drama del atardecer:<\/strong> Cuando el sol se oculta, la luz tiene que atravesar mucha m\u00e1s atm\u00f3sfera para llegar a tus ojos. En ese largo camino, el azul se \u00abpierde\u00bb y solo los tonos rojos y naranjas (que tienen ondas m\u00e1s largas y fuertes) logran cruzar, pintando el horizonte de fuego.<\/p>\n\n\n\n

El factor ‘extra’: Polvo y Humedad<\/h3>\n\n\n\n

\u00bfHas notado que en zonas como la nuestra, cerca de la costa, los atardeceres son m\u00e1s rosados o p\u00farpuras? Esto se debe a que las part\u00edculas de sal, humedad y polvo en el aire funcionan como cristales extra que refractan la luz de formas \u00fanicas, regal\u00e1ndonos postales inolvidables.<\/p>\n\n\n\n

\"\"
La interacci\u00f3n entre los rayos solares y las part\u00edculas suspendidas en la atm\u00f3sfera determina la intensidad de los colores que percibimos cada d\u00eda.<\/figcaption><\/figure>\n\n\n\n

Entender la ciencia detr\u00e1s del cielo no le quita la magia, al contrario, nos hace apreciar lo perfecto que es nuestro planeta. La pr\u00f3xima vez que veas un cielo espectacular, recuerda que est\u00e1s presenciando un fen\u00f3meno f\u00edsico que ocurre en tiempo real solo para tus ojos.<\/p>\n","protected":false},"excerpt":{"rendered":"
