Es una hermosa cortina de luz ondulante que aparece en el cielo algunas noches. Es una visi\u00f3n maravillosa e inolvidable para aquellos que tienen la suerte de contemplarla. Pero, \u00bfque provoca su aparici\u00f3n?<\/p>\n<\/div>\n<p>It all starts with our closest star, the Sun. The Sun is incredibly energetic and is constantly making what we call the solar wind &#8212; a stream of tiny particles. These fly out into space and are deflected by the magnetic field that surrounds planet Earth.<\/p>\n<p>Normalmente todo acaba ah\u00ed... pero algunas veces, el Sol produce unas erupciones enormes, conocidas como llamaradas solares, que hacen que ese viento sea todav\u00eda m\u00e1s fuerte. Cuando esto ocurre, las part\u00edculas tienen tanta energ\u00eda que no se limitan a volar hacia el campo magn\u00e9tico terrestre, sino que \u00a1chocan contra \u00e9l!<\/p>\n<p>Cuando lo hacen, siguen la direcci\u00f3n del campo magn\u00e9tico que se forma entre los polos norte y sur. En su recorrido, las part\u00edculas pueden chocar contra los gases de nuestra atm\u00f3sfera y, entonces, se libera un mont\u00f3n de energ\u00eda en forma de luz. Las part\u00edculas de viento solar que colisionan con ox\u00edgeno producen un maravilloso color verde. El nitr\u00f3geno crea fant\u00e1sticos tonos de azul y p\u00farpura. As\u00ed se forma la aurora.<\/p>\n<p>Aunque este espect\u00e1culo de luz es formidable, el viento solar produce otros efectos que pueden causar problemas. La alta energ\u00eda de las part\u00edculas puede da\u00f1ar los sat\u00e9lites que orbitan alrededor de la Tierra y poner en peligro la seguridad de los astronautas. Incluso pueden provocar apagones en nuestro planeta.<\/p>\n<p><b>Dato curioso:<\/b> The aurora is named after the Roman goddess of dawn.<\/p>\n<nav class=\"related\" aria-label=\"Relacionado\">\n<h2 class=\"related__heading\">Relacionado<\/h2>\n<div class=\"grid related__grid\">\n<div class=\"grid-item\">\n<article class=\"card focuson agency\"><a class=\"card__link\" href=\"\/es\/polarlys\/\"><\/p>\n<figure class=\"thumbnail\"><span class=\"dimmer\"><\/span><\/figure>\n<header class=\"entry\">\n<h3 class=\"heading\">dan\u00e9s<\/h3>\n<\/header>\n<p><\/a><\/article>\n<\/div>\n<div class=\"grid-item\">\n<article class=\"card focuson agency\"><a class=\"card__link\" href=\"\/es\/aurora_of_het_poollicht\/\"><\/p>\n<figure class=\"thumbnail\"><span class=\"dimmer\"><\/span><\/figure>\n<header class=\"entry\">\n<h3 class=\"heading\">holand\u00e9s<\/h3>\n<\/header>\n<p><\/a><\/article>\n<\/div>\n<div class=\"grid-item\">\n<article class=\"card focuson agency\"><a class=\"card__link\" href=\"\/es\/les_aurores\/\"><\/p>\n<figure class=\"thumbnail\"><span class=\"dimmer\"><\/span><\/figure>\n<header class=\"entry\">\n<h3 class=\"heading\">Franc\u00e9s<\/h3>\n<\/header>\n<p><\/a><\/article>\n<\/div>\n<div class=\"grid-item\">\n<article class=\"card focuson agency\"><a class=\"card__link\" href=\"\/es\/das_nordlicht\/\"><\/p>\n<figure class=\"thumbnail\"><span class=\"dimmer\"><\/span><\/figure>\n<header class=\"entry\">\n<h3 class=\"heading\">Alem\u00e1n<\/h3>\n<\/header>\n<p><\/a><\/article>\n<\/div>\n<div class=\"grid-item\">\n<article class=\"card focuson agency\"><a class=\"card__link\" href=\"\/es\/l_aurora\/\"><\/p>\n<figure class=\"thumbnail\"><span class=\"dimmer\"><\/span><\/figure>\n<header class=\"entry\">\n<h3 class=\"heading\">Italiano<\/h3>\n<\/header>\n<p><\/a><\/article>\n<\/div>\n<div class=\"grid-item\">\n<article class=\"card focuson agency\"><a class=\"card__link\" href=\"\/es\/polarlyset\/\"><\/p>\n<figure class=\"thumbnail\"><span class=\"dimmer\"><\/span><\/figure>\n<header class=\"entry\">\n<h3 class=\"heading\">noruego<\/h3>\n<\/header>\n<p><\/a><\/article>\n<\/div>\n<div class=\"grid-item\">\n<article class=\"card focuson agency\"><a class=\"card__link\" href=\"\/es\/zorza_polarna\/\"><\/p>\n<figure class=\"thumbnail\"><span class=\"dimmer\"><\/span><\/figure>\n<header class=\"entry\">\n<h3 class=\"heading\">Polaco<\/h3>\n<\/header>\n<p><\/a><\/article>\n<\/div>\n<div class=\"grid-item\">\n<article class=\"card focuson agency\"><a class=\"card__link\" href=\"\/es\/la_aurora\/\"><\/p>\n<figure class=\"thumbnail\"><span class=\"dimmer\"><\/span><\/figure>\n<header class=\"entry\">\n<h3 class=\"heading\">Espa\u00f1ol<\/h3>\n<\/header>\n<p><\/a><\/article>\n<\/div>\n<div class=\"grid-item\">\n<article class=\"card focuson agency\"><a class=\"card__link\" href=\"\/es\/auroran_norrskenet\/\"><\/p>\n<figure class=\"thumbnail\"><span class=\"dimmer\"><\/span><\/figure>\n<header class=\"entry\">\n<h3 class=\"heading\">Sueco<\/h3>\n<\/header>\n<p><\/a><\/article>\n<\/div>\n<\/div>\n<\/nav>","protected":false},"excerpt":{"rendered":"<p>Have you ever seen the aurora?
