Sv\u016fj p\u0159\u00ednos ke studiu ned\u00e1vno p\u0159inesl i radioteleskop v Arecibo, kter\u00fd se nach\u00e1z\u00ed v Portoriku (1).<\/p>\n

Sign\u00e1ly, kter\u00e9 p\u0159ich\u00e1zej\u00ed v pravideln\u00fdch intervalech, mohou b\u00fdt um\u011bl\u00e9ho p\u016fvodu.<\/p>\n

Prvn\u00ed podivn\u00e9 impulsy byly zaznamen\u00e1ny 2.11.2012 na za\u0159\u00edzen\u00ed australsk\u00e9 observato\u0159e v Parkes (2). Je zaj\u00edmav\u00e9, \u017ee ka\u017ed\u00fd r\u00e1diov\u00fd impuls (a bylo jich celkem p\u011bt), trval jen n\u011bkolik tis\u00edcin sekundy a sign\u00e1ly nechytila jen jedna observato\u0159.<\/p>\n

P\u0159esto\u017ee se p\u0159edt\u00edm nikdy nic podobn\u00e9ho zachytit nepoda\u0159ilo, austral\u0161t\u00ed astronomov\u00e9 se domn\u00edvali, \u017ee radioteleskop zachytil sign\u00e1ly z objekt\u016f nach\u00e1zej\u00edc\u00edch se nedaleko od Zem\u011b, nebo i v\u016fbec na na\u0161\u00ed planet\u011b.<\/p>\n

Ale ned\u00e1vn\u00e9 studie tuto hypot\u00e9zu vyvr\u00e1tily.<\/p>\n

T\u00fdm v\u011bdc\u016f z cel\u00e9ho sv\u011bta, zjistil, \u017ee podobn\u00e1 ohniska r\u00e1diov\u00fdch puls\u016f se vyskytuj\u00ed p\u0159ibli\u017en\u011b jednou za 10 tis\u00edc let, p\u0159i\u010dem\u017e poka\u017ed\u00e9 p\u0159ich\u00e1z\u00ed z r\u016fzn\u00fdch m\u00edst… K tomuto z\u00e1v\u011bru pomohla dosp\u011bt pr\u00e1v\u011b observato\u0159 v Arecibo, kter\u00e1 je nejv\u011bt\u0161\u00edm a nejcitliv\u011bj\u0161\u00edm radioteleskopem na sv\u011bt\u011b \u2013 pr\u016fm\u011br jeho zrcadla je 305 metr\u016f.<\/p>\n

M\u011b\u0159en\u00ed takzvan\u00e9 disperze plazmy uk\u00e1zala, \u017ee s nejv\u011bt\u0161\u00ed pravd\u011bpodobnost\u00ed se zdroje z\u00e1blesk\u016f nach\u00e1z\u00ed n\u011bkde mimo Ml\u00e9\u010dnou dr\u00e1hu. A nemohou b\u00fdt spojeny s poruchami, vyvolan\u00fdmi pohybem mezihv\u011bzdn\u00fdch elektron\u016f.<\/p>\n

„Na\u0161e zji\u0161t\u011bn\u00ed jsou obzvl\u00e1\u0161t\u011b d\u016fle\u017eit\u00e9, proto\u017ee eliminuj\u00ed jak\u00e9koliv pochybnosti o tom, \u017ee tyto z\u00e1blesky jsou kosmick\u00e9ho p\u016fvodu,\u201c – \u0159ekla jedna \u00fa\u010dastnice v\u00fdzkumn\u00e9ho t\u00fdmu, Vicky Kaspi, profesorka astrofyziky na univerzit\u011b McGill v Montrealu (3). \u201eU t\u011bchto r\u00e1diov\u00fdch vln jsou v\u0161echny p\u0159\u00edznaky toho, \u017ee k nim do\u0161lo daleko za hranicemi na\u0161\u00ed galaxie.“<\/p>\n

Ale p\u0159\u00ed\u010dina vzniku sign\u00e1lu nen\u00ed zat\u00edm jasn\u00e1. Mezi roz\u0161\u00ed\u0159en\u00fdmi verzemi je \u2013 mizej\u00edc\u00ed \u010dern\u00e1 d\u00edra (4), splynut\u00ed neutronov\u00fdch hv\u011bzd (5), nebo \u017ee z\u00e1blesk poch\u00e1z\u00ed od magnetar\u016f – neutronov\u00fdch hv\u011bzd se siln\u00fdm magnetick\u00fdm polem … (6)<\/p>\n

P\u0159esn\u011bji ur\u010dit zdroj z\u00e1blesk\u016f by mohl jen siln\u011bj\u0161\u00ed teleskop. Ale takov\u00e9 za\u0159\u00edzen\u00ed je teprve ve v\u00fdvoji.<\/p>\n

Mohou m\u00edt tajemn\u00e9 r\u00e1diov\u00e9 pulsy um\u011bl\u00fd p\u016fvod? Zcela pop\u0159\u00edt to nen\u00ed mo\u017en\u00e9. Je l\u00e1kav\u00e9 si p\u0159edstavit, \u017ee n\u011bjak\u00e1 vysp\u011bl\u00e1 civilizace po tis\u00edce let zas\u00edl\u00e1 do hlubok\u00e9ho vesm\u00edru sign\u00e1ly v nad\u011bji, \u017ee dostane odpov\u011b\u010f, nebo alespo\u0148 chce na sebe upozornit…<\/p>\n
