Kosmick\u00fd teleskop Jamese Webba (JWST), pr\u016flomov\u00fd astronomick\u00fd div, zachytil sv\u00e9 prvn\u00ed \u00fachvatn\u00e9 sn\u00edmky hv\u011bzdn\u00e9ho sv\u011btla. Po \u00fasp\u011b\u0161n\u00e9m rozvinut\u00ed sv\u00fdch 18 zlat\u00fdch zrcadel otev\u0159el teleskop sv\u00e9 \u201eo\u010di\u201c do vesm\u00edru.<\/p>\n\n
Po\u010d\u00e1te\u010dn\u00ed sn\u00edmky po\u0159\u00edzen\u00e9 JWST jsou daleko od \u201eneb\u00fdval\u00fdch pohled\u016f na vesm\u00edr\u201c, kter\u00e9 slibuje poskytnout, jakmile bude pln\u011b funk\u010dn\u00ed. V sou\u010dasn\u00e9 dob\u011b ka\u017ed\u00e9 ze zrcadel teleskopu funguje jako samostatn\u00fd dalekohled, co\u017e m\u00e1 za n\u00e1sledek 18 rozmazan\u00fdch sn\u00edmk\u016f stejn\u00e9 hv\u011bzdy, HD-84406, vzd\u00e1len\u00e9 260 sv\u011bteln\u00fdch let.<\/p>\n\n
Rozmazan\u00e9 sn\u00edmky byly zkombinov\u00e1ny a vytvo\u0159ily tak obrovskou mozaiku s v\u00edce ne\u017e dv\u011bma miliardami pixel\u016f, kter\u00e1 p\u0159edstavuje mo\u017enosti kamery pro bl\u00edzkou infra\u010dervenou oblast (NIRcam) JWST. NIRcam pracuje p\u0159i vy\u0161\u0161\u00edch teplot\u00e1ch, co\u017e j\u00ed umo\u017e\u0148uje fungovat je\u0161t\u011b p\u0159edt\u00edm, ne\u017e teleskop zcela vychladne na sv\u00e9 kryogenn\u00ed provozn\u00ed teploty.<\/p>\n\n
Astronomov\u00e9 se nyn\u00ed v\u011bnuj\u00ed delik\u00e1tn\u00edmu \u00fakolu se\u0159\u00edzen\u00ed zrcadel teleskopu.

HD-84406 byla pe\u010dliv\u011b vybr\u00e1na jako c\u00edlov\u00e1 hv\u011bzda pro prvn\u00ed pozorov\u00e1n\u00ed JWST kv\u016fli sv\u00e9 snadno rozpoznateln\u00e9 povaze a absenci bl\u00edzk\u00fdch hv\u011bzd, kter\u00e9 by mohly zp\u016fsobit zmatek.<\/p>\n\n
NIRcam hraje z\u00e1sadn\u00ed roli v ran\u00fdch pozorov\u00e1n\u00edch JWST. Detekuje infra\u010derven\u00e9 sv\u011btlo, kter\u00e9 se registruje jako teplo, co\u017e umo\u017e\u0148uje teleskopu pracovat je\u0161t\u011b p\u0159ed dosa\u017een\u00edm optim\u00e1ln\u00edch teplot chlazen\u00ed.<\/p>\n\n
Krom\u011b po\u0159izov\u00e1n\u00ed sn\u00edmk\u016f hv\u011bzdn\u00e9ho sv\u011btla po\u0159\u00eddil JWST tak\u00e9 epick\u00e9 kosmick\u00e9 selfie pomoc\u00ed specializovan\u00e9 zobrazovac\u00ed \u010do\u010dky. Selfie odhaluje, \u017ee jedno ze zrcadel teleskopu sv\u00edt\u00ed jasn\u011bji ne\u017e ostatn\u00ed, co\u017e nazna\u010duje jeho zarovn\u00e1n\u00ed s HD-84406.<\/p>\n\n
Proces se\u0159\u00edzen\u00ed zrcadel JWST je komplexn\u00ed a \u010dasov\u011b n\u00e1ro\u010dn\u00fd po\u010din. Jakmile v\u0161ak bude dokon\u010den, teleskop se vyd\u00e1 na svou misi prozkoumat nejvzd\u00e1len\u011bj\u0161\u00ed kouty vesm\u00edru, odhalit tajemstv\u00ed kosmu a roz\u0161\u00ed\u0159it na\u0161e ch\u00e1p\u00e1n\u00ed na\u0161eho m\u00edsta v n\u011bm.<\/p>\n\n
Kosmick\u00fd teleskop Jamese Webba je d\u016fkazem lidsk\u00e9 vynal\u00e9zavosti a na\u0161eho neutuchaj\u00edc\u00edho hled\u00e1n\u00ed pozn\u00e1n\u00ed.
