Durante los \u00faltimos a\u00f1os la nave SOHO de ESA \/ NASA ha demostrado que estas \u201cbolas de nieve sucia\u201d son mucho m\u00e1s comunes de lo que nadie hab\u00eda imaginado.<\/p>\n<\/div>\n<p>SOHO se dise\u00f1\u00f3 para apuntar directamente al sol, no para buscar cometas. Pero uno de sus instrumentos, llamado LASCO, que se utiliza para observar la atm\u00f3sfera exterior del sol (llamada corona), tambi\u00e9n ha permitido que SOHO se convierta en el mayor buscador de cometas de la historia.<\/p>\n<p>LASCO permite estudiar la d\u00e9bil corona bloqueando la luz brillante del sol. Por suerte, esto tambi\u00e9n permite a LASCO detectar los peque\u00f1os cometas que pasan cerca del sol. La mayor\u00eda de estos intrusos helados se acercan a menos de 800.000 km del sol. Tan cerca, que se vaporizan o se precipitan sobre su abrasadora superficie.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"3055\" data-credit=\"ESA\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2000\/09\/SOHO_spacecraft2\" data-licence=\"ESA Standard Licence\" data-licence-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Terms_and_conditions_of_use_of_images_and_videos_available_on_the_esa_website\"><img decoding=\"async\" loading=\"lazy\" style=\"max-width:100%;height:auto\" src=\"https:\/\/www.esa.int\/var\/esa\/storage\/images\/esa_multimedia\/images\/2000\/09\/soho_spacecraft2\/17865750-3-eng-GB\/SOHO_spacecraft.jpg\" alt=\"SOHO spacecraft\"><figcaption>Nave espacial SOHO<\/figcaption><\/figure>\n<p>Antes de lanzar la nave SOHO, en diciembre de 1995, s\u00f3lo se hab\u00edan descubierto 16 de estos peque\u00f1os cometas en \u00f3rbitas cercanas al sol. El 6 de julio de 2005, la nave SOHO ya hab\u00eda descubierto 990. Esto significa que SOHO ha descubierto casi la mitad de todos los cometas cuyas \u00f3rbitas han podido ser calculadas desde el comienzo de la historia. Durante este verano se espera llegar a los 1.000, y no parece que el recuento vaya a detenerse aqu\u00ed.<\/p>\n<p>Muchos de estos descubrimientos se deben a aficionados que utilizaron las im\u00e1genes de SOHO en Internet.
