Det var f\u00f8rste gang noen hadde sett den faste kjernen i hjertet av en komet.<\/p>\n<\/div>\n<p>Giottos m\u00e5l var Halleys komet, oppkalt etter den britiske astronomen Edmond Halley fra 1600-tallet. Han var den f\u00f8rste som inns\u00e5 at denne lyssterke kometen er en regelmessig gjest som vender tilbake til det indre solsystemet hvert 75.\u201376. \u00e5r. Dens neste bes\u00f8k p\u00e5 himmelen v\u00e5r er planlagt til 2061.<\/p>\n<p>Halleys komet er den mest kjente av de millioner av kometer som kretser rundt Solen. Selv n\u00e5r den befinner seg i m\u00f8rket i det ytre solsystemet, p\u00e5virker Halley fortsatt planeten v\u00e5r. Hver oktober passerer Jorden gjennom en str\u00f8m av fint st\u00f8v som kometen har etterlatt seg, noe som for\u00e5rsaker Orionidene-meteorsvermen. Halleys komet antas ogs\u00e5 \u00e5 v\u00e6re ansvarlig for Eta-Aquaridene, som finner sted hvert \u00e5r i mai. Disse meteorene, ofte kalt \u201cstjerneskudd\u201d, er lysende spor etter sm\u00e5, hurtigbevegende korn av kometrester som brenner opp i Jordens atmosf\u00e6re.<\/p>\n<figure class=\"wp-block-image size-natural\" data-width=\"400\" data-credit=\"ESA, image by AOES Medialab\" data-detail-url=\"https:\/\/www.esa.int\/ESA_Multimedia\/Images\/2011\/05\/Rosetta_orbiting_Comet_67P_Churyumov-Gerasimenko2\" 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\/2011\/05\/rosetta_orbiting_comet_67p_churyumov-gerasimenko2\/18245884-2-eng-GB\/Rosetta_orbiting_Comet_67P_Churyumov-Gerasimenko.jpg\" alt=\"Rosetta orbiting Comet 67P\/Churyumov-Gerasimenko\"><figcaption>Rosetta i bane rundt kometen 67P\/Churyumov-Gerasimenko<\/figcaption><\/figure>\n<p>Siden Giottos bemerkelsesverdige suksess har andre kometer blitt unders\u00f8kt av romfart\u00f8y.

Rosetta skal fly ved siden av kjernen og foreta en grundig unders\u00f8kelse av endringene som skjer n\u00e5r den varmes opp av solen. Den skal ogs\u00e5 slippe ut et lite romfart\u00f8y kalt Philae, som skal gjennomf\u00f8re den f\u00f8rste myke landingen p\u00e5 en komet!<\/p>","protected":false},"excerpt":{"rendered":"<p>On 13 March 1986, ESA\u2019s Giotto spacecraft sent back pictures of a black, potato-shaped object that was blasting bright jets of material into space.
