Od zah\u00e1jen\u00ed provozu v roce 1996 se kosmick\u00e1 lo\u010f SOHO, spole\u010dn\u00fd projekt ESA a NASA, nep\u0159etr\u017eit\u011b soust\u0159ed\u00ed na pozorov\u00e1n\u00ed obrovsk\u00e9ho, \u017ehnouc\u00edho Slunce. Jeden z jej\u00edch p\u0159\u00edstroj\u016f, naz\u00fdvan\u00fd LASCO, slou\u017e\u00ed k pozorov\u00e1n\u00ed vn\u011bj\u0161\u00ed atmosf\u00e9ry Slunce (korony). Kamera LASCO s ostr\u00fdm zrakem v\u0161ak prok\u00e1zala tak\u00e9 \u00fa\u017easnou schopnost nach\u00e1zet mal\u00e9 kousky \u0161pinav\u00e9ho ledu, kter\u00fdm \u0159\u00edk\u00e1me komety. Do z\u00e1\u0159\u00ed 2010 objevila sonda SOHO v\u00edce ne\u017e 1 900 komet, co\u017e je v\u00edce ne\u017e v\u0161ichni ostatn\u00ed objevitel\u00e9 komet dohromady. To nen\u00ed \u0161patn\u00fd v\u00fdsledek pro kosmickou sondu, kter\u00e1 byla navr\u017eena ke studiu na\u0161\u00ed nejbli\u017e\u0161\u00ed hv\u011bzdy.<\/p>\n<\/div>\n

Komety jsou kusy ledu a prachu \u2013 \u2018zbytky\u2019 z doby vzniku planet p\u0159ed 4,5 miliardami let. V\u0161echny komety ob\u00edhaj\u00ed kolem Slunce a mnoho z nich jsou komety typu \u201esungrazers\u201c, kter\u00e9 prol\u00e9t\u00e1vaj\u00ed velmi bl\u00edzko jeho \u017ehav\u00e9ho povrchu. N\u011bkter\u00e9 z komet ob\u00edhaj\u00edc\u00edch kolem Slunce se na sn\u00edmc\u00edch sondy SOHO jev\u00ed jako drobn\u00e9 te\u010dky nebo pruhy \u2013 ne v\u0161echny v\u0161ak tento ohniv\u00fd pr\u016flet p\u0159e\u017eij\u00ed. Mnoh\u00e9 z nich se vypa\u0159\u00ed nebo se z\u0159\u00edt\u00ed p\u0159\u00edmo do hv\u011bzdy.<\/p>\n

P\u0159ibli\u017en\u011b 85% objev\u016f sondy SOHO tvo\u0159\u00ed \u00falomky kdysi mohutn\u00e9 komety, kter\u00e1 se rozpadla p\u0159i smrteln\u00e9m p\u00e1du kolem Slunce, pravd\u011bpodobn\u011b p\u0159ed mnoha stalet\u00edmi.<\/p>\n

Pokud jde o pozorov\u00e1n\u00ed komet, m\u00e1 SOHO oproti v\u0161em ostatn\u00edm jednu velkou v\u00fdhodu: svou polohu mezi Sluncem a Zem\u00ed. D\u00edky tomu, \u017ee LASCO blokuje osl\u0148uj\u00edc\u00ed z\u00e1\u0159i Slunce, m\u016f\u017ee pozorovat oblasti, kter\u00e9 by jinak byly viditeln\u00e9 pouze b\u011bhem \u00fapln\u00e9ho slune\u010dn\u00edho zatm\u011bn\u00ed.<\/p>\n

Samoz\u0159ejm\u011b, \u017ee samotn\u00e1 sonda LASCO tyto detekce neprov\u00e1d\u00ed.
