\"slne\u010dn\u00e1
\nV ned\u00e1vnej tla\u010dovej spr\u00e1ve univerzitn\u00fd astrofyzik Meredith MacGregor uviedol, \u017ee Proxima Centauri m\u00f4\u017ee by\u0165 mal\u00e1, slab\u00e1 hviezda. Nenechajte sa v\u0161ak zmias\u0165 jeho malou ve\u013ekos\u0165ou a jemn\u00fdm vy\u017earovan\u00edm. M\u00e1 najmenej dve plan\u00e9ty, Proxima Centauri a a Proxima Centauri b. Je to 20 bili\u00f3nov m\u00ed\u013e nad na\u0161im vlastn\u00fdm svetlom. Proxima Centauri je \u010derven\u00fd trpasl\u00edk, ktor\u00fd je asi osminou hmotnosti na\u0161ej vlastnej hviezdy a je vzdialen\u00fd \u0161tyri sveteln\u00e9 roky.<\/p>\n

MacGregor je docentom na Boulderovom centre astrofyziky a vesm\u00edrnej astron\u00f3mie University of Colorado Boulder Center a Katedre astrofyzik\u00e1lnych a planet\u00e1rnych vied (APS). Jej t\u00edm pou\u017eil s\u00fastavu deviatich po\u013en\u00fdch teleskopov a jednu orbit\u00e1lnu observat\u00f3rium na pozorovanie Proximy Centauri zhruba 40 hod\u00edn. Proxima Centauri po\u010das v\u00fdskumu vysunul mas\u00edvny oblak \u017eiarenia, \u010d\u00edm sa stal jedn\u00fdm z najv\u00e4\u010d\u0161\u00edch, ak\u00e9 boli kedy v Mlie\u010dnej dr\u00e1he pozorovan\u00e9.<\/p>\n

Hviezda pod\u013ea MacGregora pre\u0161la z ultrafialov\u00fdch vlnov\u00fdch d\u013a\u017eok z priemeru na<\/p>\n

14 000-kr\u00e1t jasnej\u0161ie v priebehu nieko\u013ek\u00fdch sek\u00fand.<\/p><\/blockquote>\n

MacGregor uviedol, \u017ee ak by \u017eivot existoval na plan\u00e9te najbli\u017e\u0161ej k Proxima Centauri, musel by sa trochu l\u00ed\u0161i\u0165 od \u017eivota na Zemi. V\u00fdskumn\u00edk dodal, \u017ee \u013eudsk\u00e1 bytos\u0165 to bude ma\u0165 \u0165a\u017ek\u00e9.<\/p>\n

Vedci sa u\u017e desa\u0165ro\u010dia pozeraj\u00fa na Proxima Centauri ako na mo\u017en\u00fd domov mimo na\u0161ej vlastnej slne\u010dnej s\u00fastavy. Proxima Centauri b, jedna z exoplan\u00e9t, je podobn\u00e1 Zemi a nach\u00e1dza sa v \u201eob\u00fdvate\u013enej oblasti\u201c s teplotami ved\u00facimi k tvorbe kvapalnej vody.<\/p>\n

\u201eVe\u013ea exoplan\u00e9t, ktor\u00e9 sme doposia\u013e na\u0161li, je okolo t\u00fdchto typov hviezd,\u201c vysvetlila. \u201eH\u00e1\u010dik je v tom, \u017ee s\u00fa ove\u013ea akt\u00edvnej\u0161\u00ed ako na\u0161e slnko. Svetlice vzplan\u00fa ove\u013ea \u010dastej\u0161ie a intenz\u00edvnej\u0161ie.\u201c<\/p>\n

MacGregor a jej t\u00edm v roku 2019 nasmerovali svoje astronomick\u00e9 pr\u00edstroje na Proxima Centauri na 40 hod\u00edn po\u010das nieko\u013ek\u00fdch mesiacov, aby zachytili tento neobvykl\u00fd jav. Pou\u017e\u00edvali Atacama Large Millimeter Array (ALMA), NASA Transiting Exoplanet Survey Satellite (TESS) a Hubbleov vesm\u00edrny teleskop. Piati z deviatich fotografov mali to \u0161\u0165astie, \u017ee zachytili ve\u013ekolep\u00fa erupciu a jej \u0161irok\u00e9 spektrum \u017eiarenia.<\/p>\n

MacGregor uviedol, \u017ee je to v\u00f4bec prv\u00fdkr\u00e1t, \u010do videli tento druh pokrytia hviezdnou erupciou viacn\u00e1sobnou vlnovou d\u013a\u017ekou.<\/p>\n

T\u00edm UK Boulder mohol pomocou tejto vrstvenej techniky zachyti\u0165 jednu z najpresnej\u0161\u00edch slne\u010dn\u00fdch erupci\u00ed, ak\u00e9 kedy boli v Mlie\u010dnej ceste vidie\u0165. 1. m\u00e1ja 2019 znamenal 7-sekundov\u00fd incident nov\u00fd m\u00ed\u013enik. Neprodukovalo ve\u013ek\u00e9 mno\u017estvo vidite\u013en\u00e9ho svetla, namiesto toho vy\u017earovalo ultrafialov\u00e9 a r\u00e1diov\u00e9 vlny, be\u017ene zn\u00e1me ako \u201emilimetrov\u00e9\u201c \u017eiarenie.<\/p>\n

100 – kr\u00e1t v\u00e4\u010d\u0161ia ako Slne\u010dn\u00e1<\/h2>\n

\u201eV minulosti sme nevedeli, \u017ee hviezdy m\u00f4\u017eu vzplan\u00fa\u0165 v milimetrovom rozsahu, tak\u017ee je to prv\u00fdkr\u00e1t, \u010do h\u013ead\u00e1me milimetrov\u00e9 svetlice,\u201c povedala. Svetlica viden\u00e1 na hviezde bola takmer 100 – kr\u00e1t v\u00e4\u010d\u0161ia ako ak\u00e1ko\u013evek erupcia pozorovan\u00e1 na zemskom slnku. Tento druh energie m\u00e1 schopnos\u0165 ni\u010di\u0165 atmosf\u00e9ru plan\u00e9ty a pokr\u00fdva\u0165 formy \u017eivota smrtiacim \u017eiaren\u00edm.<\/p>\n

MacGregor uviedol, \u017ee slne\u010dn\u00e9 plan\u00e9ty zasiahli plan\u00e9ty Proxima Centauri nie raz za storo\u010die, ale najmenej raz denne, ak nie mnohokr\u00e1t za de\u0148. Dodala, \u017ee takmer ur\u010dite by existovali e\u0161te bizarnej\u0161ie druhy vzplanut\u00ed, ktor\u00e9 by vysvet\u013eovali nov\u00e9 typy javov, o ktor\u00fdch predt\u00fdm neuva\u017eovali.<\/p>\n

Udalos\u0165 bola pozorovan\u00e1 1. m\u00e1ja 2019 a trvala iba 7 sek\u00fand. Aj ke\u010f nevytv\u00e1ral ve\u013ea vidite\u013en\u00e9ho svetla, generovala obrovsk\u00fd n\u00e1rast ultrafialov\u00e9ho aj r\u00e1diov\u00e9ho alebo \u201emilimetrov\u00e9ho\u201c \u017eiarenia. <\/p>\n

Ke\u010f Zem pl\u00e1va slne\u010dnou s\u00fastavou, vietor n\u00e1m nikdy nie je v chrbte; na ka\u017edom kroku zo slnka vych\u00e1dzaj\u00fa pr\u00fady hor\u00facich nabit\u00fdch \u010dast\u00edc naz\u00fdvan\u00fdch slne\u010dn\u00fd vietor, ktor\u00e9 nar\u00e1\u017eaj\u00fa na na\u0161u plan\u00e9tu r\u00fdchlos\u0165ou 1,6 mili\u00f3na km\/h.<\/p>\n

Na\u0161\u0165astie pre n\u00e1s, magnetick\u00fd \u0161t\u00edt Zeme odkl\u00e1\u0148a a demontuje najtvrd\u0161\u00ed z t\u00fdchto vetrov, \u010do umo\u017e\u0148uje prenikn\u00fa\u0165 do atmosf\u00e9ry plan\u00e9ty nie\u010do viac ako tepl\u00fd v\u00e1nok.
