V\u011bdci z Kalifornsk\u00e9 univerzity v Berkeley znovu zkoumaj\u00ed 100 z\u00e1hadn\u00fdch r\u00e1diov\u00fdch sign\u00e1l\u016f detekovan\u00fdch v hlubok\u00e9m vesm\u00edru a doufaj\u00ed, \u017ee kone\u010dn\u011b zjist\u00ed, zda n\u011bkter\u00fd z nich poskytuje d\u016fkazy o mimozemsk\u00e9m \u017eivot\u011b.

Hled\u00e1n\u00ed mimozemsk\u00e9 inteligence (SETI) bylo v\u017edy omezeno v\u00fdpo\u010detn\u00edm v\u00fdkonem. Anal\u00fdza obrovsk\u00fdch objem\u016f r\u00e1diov\u00fdch dat vy\u017eadovala schopnosti, kter\u00e9 byly d\u0159\u00edve dostupn\u00e9 pouze velk\u00fdm instituc\u00edm. V roce 1999 si v\u0161ak v\u011bdci uv\u011bdomili potenci\u00e1l vyu\u017eit\u00ed kolektivn\u00edho v\u00fdpo\u010detn\u00edho v\u00fdkonu osobn\u00edch po\u010d\u00edta\u010d\u016f. Tak se zrodil projekt SETI@home<\/strong>, kter\u00fd vyzval kohokoli ke sta\u017een\u00ed softwaru, kter\u00fd pasivn\u011b analyzoval data shrom\u00e1\u017ed\u011bn\u00e1 observato\u0159\u00ed Arecibo v Portoriku. <\/p>\n Toto nebyl jen teoretick\u00fd experiment; m\u011b\u0159\u00edtko bylo p\u016fsobiv\u00e9. B\u011bhem n\u011bkolika dn\u00ed se projektu z\u00fa\u010dastnilo v\u00edce ne\u017e 200 000 lid\u00ed a b\u011bhem jednoho roku bylo sta\u017eeno v\u00edce ne\u017e 2 miliony kopi\u00ed z v\u00edce ne\u017e 100 zem\u00ed. Kombinovan\u00fd v\u00fdpo\u010detn\u00ed v\u00fdkon t\u011bchto dom\u00e1c\u00edch po\u010d\u00edta\u010d\u016f umo\u017enil v\u00fdzkumn\u00edk\u016fm analyzovat data zp\u016fsoby, kter\u00e9 byly d\u0159\u00edve nemo\u017en\u00e9. Jak poznamenal Eric Korpela, jeden z astronom\u016f na projektu, d\u00edky tomu se jedn\u00e1 o \u201enejcitliv\u011bj\u0161\u00ed \u00fazkop\u00e1smov\u00e9 vyhled\u00e1v\u00e1n\u00ed ve velk\u00fdch oblastech oblohy<\/strong> \u201c. <\/p>\n Data nebyla jen o poslechu jasn\u00fdch mimozemsk\u00fdch zpr\u00e1v. Pohyb Zem\u011b kolem Slunce a mo\u017en\u00fd pohyb jak\u00e9koli vys\u00edlaj\u00edc\u00ed mimozemsk\u00e9 civilizace vytvo\u0159il Doppler\u016fv jev, posunuj\u00edc\u00ed frekvence v pr\u016fb\u011bhu \u010dasu. Aby to bylo mo\u017en\u00e9 vysv\u011btlit, v\u00fdzkumn\u00edci vyvinuli sofistikovan\u00e9 algoritmy pro anal\u00fdzu \u0161irok\u00e9ho rozsahu mo\u017en\u00fdch zm\u011bn frekvence. To vy\u017eadovalo enormn\u00ed v\u00fdpo\u010detn\u00ed v\u00fdkon \u2013 podle Davida Andersona, jednoho z po\u010d\u00edta\u010dov\u00fdch v\u011bdc\u016f projektu, zv\u00fd\u0161en\u00fd v\u00edce ne\u017e 10 000kr\u00e1t \u2013 ale distribuovan\u00e1 s\u00ed\u0165 po\u010d\u00edta\u010d\u016f to umo\u017enila. <\/p>\n Do dokon\u010den\u00ed SETI@home v roce 2020 t\u00fdm identifikoval p\u0159ibli\u017en\u011b 12 miliard zaj\u00edmav\u00fdch sign\u00e1l\u016f. Tyto sign\u00e1ly byly pomoc\u00ed superpo\u010d\u00edta\u010d\u016f z\u00fa\u017eeny na asi 2 miliony a pot\u00e9 d\u00e1le zp\u0159esn\u011bny odstran\u011bn\u00edm ru\u0161en\u00ed ze satelit\u016f, vys\u00edl\u00e1n\u00ed a dokonce i dom\u00e1c\u00edch spot\u0159ebi\u010d\u016f. Nakonec tento proces identifikoval p\u0159ibli\u017en\u011b 100 sign\u00e1l\u016f hodn\u00fdch dal\u0161\u00edho studia. <\/p>\n Od \u010dervence 2025 v\u011bdci pou\u017e\u00edvaj\u00ed \u010d\u00ednsk\u00fd radioteleskop FAST (Fight-Meter Aperture Radio Telescope) k op\u011btovn\u00e9mu zkoum\u00e1n\u00ed t\u011bchto oblast\u00ed vesm\u00edru.
