De siste \u00e5rene har imidlertid romfart\u00f8yet SOHO, som drives av ESA og NASA, vist at disse \u201cskitne sn\u00f8ballene\u201d er langt vanligere enn noen kunne forestille seg.<\/p>\n<\/div>\n<p>SOHO ble utviklet for \u00e5 observere Solen, ikke for \u00e5 lete etter kometer. Et av instrumentene, kalt LASCO, brukes til \u00e5 observere Solens ytre atmosf\u00e6re (koronaen). Men takket v\u00e6re dette instrumentet har SOHO ogs\u00e5 blitt den st\u00f8rste kometjegeren i historien.<\/p>\n<p>LASCO studerer den svake koronaen ved \u00e5 blokkere det sterke lyset fra Solen. Tilfeldigvis gj\u00f8r dette ogs\u00e5 at LASCO kan oppdage sm\u00e5 kometer som passerer sv\u00e6rt n\u00e6r Solen. De fleste av disse isete inntrengerne suser forbi s\u00e5 n\u00e6r som 800 000 km fra Solens overflate \u2013 s\u00e5 n\u00e6r at de fordamper eller faller ned i dens gl\u00f8dende ovn.<\/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-romfart\u00f8yet<\/figcaption><\/figure>\n<p>F\u00f8r SOHO ble skutt opp i desember 1995, var det kun oppdaget 16 kometer som passerer tett forbi Solen ved hjelp av romfart\u00f8y. Per 6. juli 2005 hadde SOHO alene funnet ikke mindre enn 990. Dette betyr at SOHO har oppdaget nesten halvparten av alle kometer hvis baner er beregnet siden historien begynte. Det svimlende tallet forventes \u00e5 passere 1 000 denne sommeren og fortsette \u00e5 stige.<\/p>\n<p>Mange av disse oppdagelsene er gjort av amat\u00f8rer ved hjelp av SOHO-bilder p\u00e5 internett.
