Uvoln\u011bn\u00ed zdroje energie: Alfvenovy vlny<\/h3>\n

Nov\u00e1 studie publikovan\u00e1 v Nature Communications<\/em> identifikovala mechanismus, kter\u00fd poh\u00e1n\u00ed alespo\u0148 jeden typ pol\u00e1rn\u00ed z\u00e1\u0159e: pol\u00e1rn\u00ed oblouky<\/strong>. V\u011bdci zjistili, \u017ee tyto oblouky nejsou jen n\u00e1hodn\u00fdm vedlej\u0161\u00edm produktem slune\u010dn\u00ed aktivity; aktivn\u011b se \u017eiv\u00ed<\/em> n\u011b\u010d\u00edm, \u010demu se \u0159\u00edk\u00e1 Alfv\u00e9novy vlny<\/strong>. <\/p>\n

Tyto vlny jsou jedine\u010dn\u00e9 pro kosmickou plazmu \u2013 ionizovan\u00fd plyn, kter\u00fd tvo\u0159\u00ed v\u011bt\u0161inu vesm\u00edru \u2013 a \u0161\u00ed\u0159\u00ed se pod\u00e9l magnetick\u00fdch silo\u010dar Zem\u011b. NASA je popisuje jako jak\u00e9si \u201evesm\u00edrn\u00e9 baterie\u201c, kter\u00e9 urychluj\u00ed nabit\u00e9 \u010d\u00e1stice na vysokou rychlost.

Pr\u016flom nebyl pl\u00e1nov\u00e1n; vzniklo d\u00edky \u0161\u0165astn\u00e9 n\u00e1hod\u011b. V roce 2015 provedla simult\u00e1nn\u00ed m\u011b\u0159en\u00ed pol\u00e1rn\u00edho oblouku jak arm\u00e1da, tak kosmick\u00e9 lod\u011b NASA. Tato kombinovan\u00e1 perspektiva, po dlouh\u00e9 \u010dasov\u00e9 obdob\u00ed, kone\u010dn\u011b odhalila z\u00e1sadn\u00ed spojen\u00ed mezi Alfv\u00e9nov\u00fdmi vlnami a tvorbou oblouku.<\/strong> <\/p>\n

“Tato kombinovan\u00e1 pozorov\u00e1n\u00ed poskytla r\u016fzn\u00e9 perspektivy po dostate\u010dn\u011b dlouhou dobu, aby odhalila v\u00edce informac\u00ed o podm\u00ednk\u00e1ch ve vesm\u00edru, kter\u00e9 p\u0159isp\u011bly k vytvo\u0159en\u00ed oblouku,” vysv\u011btluje NASA. <\/p>\n<\/blockquote>\n
