Vedeck\u00e1 odmena za odhalenie planet\u00e1rnej dru\u017einy Alpha Centauri by mohla by\u0165 obrovsk\u00e1.

Tento relat\u00edvne lacn\u00fd teleskop s n\u00e1zvom Toliman si zabezpe\u010dil financovanie vo v\u00fd\u0161ke viac ako 500 000 dol\u00e1rov od austr\u00e1lskej vl\u00e1dy na pokra\u010dovanie v\u00fdvoja, ozn\u00e1mil t\u00edm 16. novembra.

Mal\u00fd teleskop ve\u013ekosti \u0161katule od top\u00e1nok je navrhnut\u00fd s konkr\u00e9tnym cie\u013eom: h\u013eada\u0165 plan\u00e9ty v syst\u00e9me Alpha Centauri, konkr\u00e9tne ak\u00fako\u013evek v jeho ob\u00fdvate\u013enej z\u00f3ne, v oblasti ohriatej hviezdami, v ktorej by mohla tekut\u00e1 voda pretrv\u00e1va\u0165 na skalnatom povrchu sveta.

V roku 2012 si vedci mysleli, \u017ee na\u0161li plan\u00e9tu obiehaj\u00facu okolo Alpha Centauri B, nazvan\u00fa Alpha Centauri Bb, ale v roku 2015 in\u00ed v\u00fdskumn\u00edci zdanlivo vyl\u00fa\u010dili existenciu plan\u00e9ty. Vy\u0161etrovanie Proximy Centauri sa uk\u00e1zalo by\u0165 plodnej\u0161ie <\/em>a odhalilo svet pravdepodobne ve\u013ekosti Zeme naz\u00fdvan\u00fd Proxima b, zatia\u013e \u010do \u010fal\u0161ia plan\u00e9ta \u2013 Proxima c \u2013 bola tie\u017e nazna\u010den\u00e1. <\/p>\n
Toliman, starovek\u00e9 arabsk\u00e9 meno pre Alpha Centauri, ktor\u00e9 v\u0161ak znamen\u00e1 aj Telescope for Orbital Locus Interferometric Monitoring of our Astronomical Neighborhood, je navrhnut\u00fd na lov plan\u00e9t okolo Alpha Centauri A a B. \u010casti teleskopu s\u00fa \u201eu\u017e na z\u00e1klade zmluvy\u201c pre v\u00fdstavbu, hovor\u00ed Tuthill, zatia\u013e \u010do predchodca misie na testovanie technol\u00f3gie s n\u00e1zvom Toliboy bol vypusten\u00fd za\u010diatkom tohto roka na satelite CUAVA-1k Medzin\u00e1rodnej vesm\u00edrnej stanici. <\/p>\n
Na univerzite v Sydney prebieha laborat\u00f3rne testovanie a simula\u010dn\u00e9 pr\u00e1ce na technol\u00f3gi\u00e1ch pre Tolimana, hovor\u00ed Tuthill, pri\u010dom t\u00edm teraz pracuje na plnohodnotnom prototype. Hoci niektor\u00e9 aspekty misie e\u0161te nie s\u00fa vyrie\u0161en\u00e9, ako napr\u00edklad let rakety do vesm\u00edru a jej stanica na obe\u017enej dr\u00e1he Zeme, samotn\u00e1 technol\u00f3gia je z ve\u013ekej \u010dasti pripraven\u00e1 na spustenie. <\/p>\n
\u201eKomponenty tohto teleskopu s\u00fa dos\u0165 vyspel\u00e9,\u201c hovor\u00ed Guyon, ktor\u00fd je tie\u017e predsedom projektu Breakthrough Watch v r\u00e1mci Milner’s Breakthrough Initiatives, ktor\u00e9ho cie\u013eom je n\u00e1js\u0165 plan\u00e9ty okolo Alpha Centauri a \u010fal\u0161\u00edch bl\u00edzkych hviezd. <\/p>\n
