Maar de laatste jaren heeft het SOHO-ruimtevaartuig van ESA en NASA laten zien dat er veel meer van die 'vieze sneeuwballen' zijn dan je zou denken\u2026<\/p>\n<\/div>\n<p>SOHO is eigenlijk gemaakt om de zon te bestuderen en niet om op zoek te gaan naar kometen. Met \u00e9\u00e9n van zijn instrumenten, LASCO, bestudeert de sonde de buitenste atmosfeer van de zon (de corona). Dankzij dit instrument is SOHO ook uitgegroeid tot de allergrootste kometenjager ooit.<\/p>\n<p>LASCO bestudeert de zwakke corona door het felle zonlicht af te schermen. Toevallig kan LASCO daardoor ook kleine kometen ontdekken die dicht langs de zon scheren. De meeste van die zonscheerders schieten langs de zon op minder dan achthonderdduizend kilometer. Dat is zo dichtbij, dat ze verdampen of in de vlammenzee van de zon neerstorten.<\/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>SOHO-ruimtevaartuig<\/figcaption><\/figure>\n<p>V\u00f3\u00f3r de lancering van SOHO, in december 1995, hadden ruimtesondes nog maar zestien zonscheerders ontdekt.
