Ahoj, mlad\u00ed pr\u016fzkumn\u00edci! Jste p\u0159ipraveni na dal\u0161\u00ed vzru\u0161uj\u00edc\u00ed cestu vesm\u00edrem? Spole\u010dn\u011b s Paxim odhal\u00edte tajemstv\u00ed vesm\u00edru. Od vzd\u00e1len\u00fdch planet p\u0159es z\u00e1\u0159\u00edc\u00ed hv\u011bzdy a\u017e po v\u00ed\u0159\u00edc\u00ed galaxie \u2013 je tu tolik v\u011bc\u00ed k objevov\u00e1n\u00ed!<\/b><\/p>\n

P\u0159i ka\u017ed\u00e9m dobrodru\u017estv\u00ed se dozv\u00edme, jak\u00e9 \u00fa\u017easn\u00e9 v\u011bci se ve vesm\u00edru d\u011bj\u00ed, jak ESA zkoum\u00e1 m\u00edsta za hranicemi Zem\u011b a pro\u010d je vesm\u00edr tak neuv\u011b\u0159iteln\u00fdm m\u00edstem. Tak se p\u0159ipravte, zapojte svou fantazii a vydejte se s n\u00e1mi na \u00fa\u017easnou misi, p\u0159i kter\u00e9 spole\u010dn\u011b prozkoum\u00e1me z\u00e1zraky vesm\u00edru!<\/b><\/p>\n

V z\u00e1\u0159\u00ed 2023, vysoko nad planetou Zem\u00ed, vzn\u00e1\u0161ej\u00edc\u00ed se v nekone\u010dn\u00e9 temnot\u011b vesm\u00edru, se dalekohled Euclid Evropsk\u00e9 kosmick\u00e9 agentury probudil. Jeho velkolep\u00e1 mise k prozkoum\u00e1n\u00ed tajemn\u00e9ho vesm\u00edru pr\u00e1v\u011b za\u010dala!<\/p>\n

\u201cNem\u016f\u017eu se do\u010dkat, a\u017e za\u010dnu p\u00e1trat po kosmick\u00fdch tajemstv\u00edch!\u201d zvolal Euclid nad\u0161en\u011b. Ne\u017e se v\u0161ak mohl pustit do pr\u00e1ce, museli v\u011bdci na Zemi zkontrolovat, zda v\u0161echny Euclidovy speci\u00e1ln\u00ed vesm\u00edrn\u00e9 o\u010di funguj\u00ed spr\u00e1vn\u011b.<\/p>\n

Euclid nebyl na t\u00e9to misi s\u00e1m. Hned po jeho boku byl Paxi, ofici\u00e1ln\u00ed mimozemsk\u00fd pr\u016fzkumn\u00edk ESA z dalek\u00e9 planety, kter\u00fd miloval v\u0161echno, co se t\u00fdkalo vesm\u00edru. \u201cTo je tak vzru\u0161uj\u00edc\u00ed, Euclide! Jsem zv\u011bdav\u00fd, jak\u00e1 tajemstv\u00ed odhal\u00edme jako prvn\u00ed!\u201d \u0159ekl Paxi a jeho ant\u00e9ny se v o\u010dek\u00e1v\u00e1n\u00ed zachv\u011bly.<\/p>\n

Kdy\u017e Euclid testoval sv\u016fj zrak, zahl\u00e9dl n\u011bco podivn\u00e9ho pobl\u00ed\u017e galaxie zvan\u00e9 NGC 6505. \u201cHmm\u2026 co to je?\u201d zamyslel se. P\u0159\u00edmo uprost\u0159ed galaxie Euclid zahl\u00e9dl z\u00e1\u0159\u00edc\u00ed prstenec sv\u011btla! Ve vesm\u00edru v\u0161ak neplula \u017e\u00e1dn\u00e1 ob\u0159\u00ed hv\u011bzda ve tvaru obru\u010de\u2026 tak odkud se to vzalo?<\/p>\n

Zp\u00e1tky na Zemi se v\u011bdec jm\u00e9nem Bruno zad\u00edval na fotografii, kterou mu poslal Euclid, a v\u0161iml si toho sam\u00e9ho podivn\u00e9ho prstence. \u201cCo by to mohlo b\u00fdt?\u201d zamyslel se a po\u0161kr\u00e1bal se na hlav\u011b.<\/p>\n

Najednou se vedle Euclida a Paxiho objevil z\u00e1\u0159iv\u00fd, kouzeln\u00fd v\u00edr sv\u011btla. Z hv\u011bzdn\u00e9ho prachu vystoupil profesor Einstein se sv\u00fdmi b\u00edl\u00fdmi, na\u010dechran\u00fdmi vlasy a jisk\u0159iv\u00fdma o\u010dima.<\/p>\n

\u201cNo, no, no!\u201d \u0159ekl Einstein s \u0161irok\u00fdm \u00fasm\u011bvem na tv\u00e1\u0159i. \u201cVypad\u00e1 to, \u017ee jsi na\u0161el n\u011bco opravdu v\u00fdjime\u010dn\u00e9ho, Euclide! To je Einstein\u016fv prsten; je pojmenovan\u00fd po mn\u011b!\u201d<\/p>\n

\u201cPrsten? Ale odkud se tu vzal?\u201d zeptal se Paxi. Euclid p\u0159ibl\u00ed\u017eil obraz sv\u00fdmi v\u00fdkonn\u00fdmi vesm\u00edrn\u00fdmi o\u010dima a chystal se to prozkoumat.<\/p>\n

\u201cAch! Vysv\u011btl\u00edm v\u00e1m to,\u201d \u0159ekl Einstein a posunul si kulat\u00e9 br\u00fdle. \u201cD\u00edvali jste se n\u011bkdy do kalu\u017ee a v\u0161imli jste si, jak se obloha nebo stromy zdaj\u00ed b\u00fdt vln\u00edc\u00ed se a pok\u0159iven\u00e9? To se d\u011bje proto, \u017ee voda oh\u00fdb\u00e1 sv\u011btlo. No, ve vesm\u00edru, gravitace<\/a> \u201dUm\u00ed to sam\u00e9 \u2013 taky oh\u00fdb\u00e1 sv\u011btlo!\u201c<\/p>\n

Euclid vydechl: \u201cTak\u017ee\u2026 ten prstenec vlastn\u011b nen\u00ed prstenec? Je to sv\u011btlo p\u0159ich\u00e1zej\u00edc\u00ed ze vzd\u00e1len\u00e9ho objektu, kter\u00e9 bylo zkresleno a prot\u00e1hnuto velkou galaxi\u00ed v pop\u0159ed\u00ed?\u201d<\/p>\n

\u201cP\u0159esn\u011b tak!\u201d zvolal Einstein. \u201cA objekt, kter\u00fd vys\u00edl\u00e1 sv\u011btlo, je jin\u00e1 galaxie, vzd\u00e1len\u00e1 mnoho miliard kilometr\u016f. P\u0159edstav si, \u017ee se tv\u016fj kamar\u00e1d Paxi schov\u00e1v\u00e1 za obrovskou akv\u00e1riovou sklen\u011bnou n\u00e1dobou. Nem\u016f\u017ee\u0161 ho vid\u011bt p\u0159\u00edmo, ale sklo oh\u00fdb\u00e1 sv\u011btlo, tak\u017ee se jeho obli\u010dej po okraj\u00edch protahuje do legra\u010dn\u00edho tvaru! P\u0159esn\u011b to se d\u011bje ve vesm\u00edru! Gravitace t\u00e9 velk\u00e9 galaxie oh\u00fdb\u00e1 a protahuje sv\u011btlo ze skryt\u00e9 galaxie a deformuje ho do z\u00e1\u0159\u00edc\u00edho kruhu. \u0158\u00edk\u00e1me tomu gravita\u010dn\u00ed \u010do\u010dka, ale vypad\u00e1 to jako kouzelnick\u00fd trik!\u201d<\/p>\n

\u00a0\u201cP\u00e1ni! Tak\u017ee galaxie funguje jako obrovsk\u00e1 kosmick\u00e1 lupa? To je neuv\u011b\u0159iteln\u00e9!\u201d rozz\u00e1\u0159il se Paxi.<\/p>\n

Bruno, kter\u00fd st\u00e1le komunikoval s Euclidem a poslouchal ze Zem\u011b, vysko\u010dil na nohy. \u201cEuclide, objevil jsi jeden z nejjasn\u011bj\u0161\u00edch Einsteinov\u00fdch prstenc\u016f, jak\u00e9 kdy byly spat\u0159eny! Tyhle jevy jsou velmi vz\u00e1cn\u00e9 a t\u011b\u017eko pozorovateln\u00e9. Jak \u0159ekl Paxi, m\u016f\u017eeme je pou\u017e\u00edt jako kosmick\u00e1 zv\u011bt\u0161ovac\u00ed skla k v\u00fdzkumu vzd\u00e1len\u00fdch galaxi\u00ed a dokonce i k pozn\u00e1v\u00e1n\u00ed temn\u00e9 hmoty, t\u00e9 z\u00e1hadn\u00e9 l\u00e1tky, kter\u00e1 vypl\u0148uje n\u00e1\u0161 vesm\u00edr!\u201d<\/p>\n

Euclid se py\u0161n\u011b usm\u00e1l. \u201cA to je teprve za\u010d\u00e1tek! Pokus\u00edm se naj\u00edt je\u0161t\u011b tis\u00edce dal\u0161\u00edch!\u201d<\/p>\n

Einstein, nad\u0161en\u00fd t\u00edmto objevem dalekohledu, odpov\u011bd\u011bl: \u201cVesm\u00edr je pln\u00fd tajemstv\u00ed, Euclide. Pokra\u010duj v hled\u00e1n\u00ed, jsem si jist\u00fd, \u017ee je ti souzeno zapsat se do d\u011bjin!\u201d<\/p>\n

S t\u011bmito slovy se velk\u00fd v\u011bdec vytratil ve v\u00edru hv\u011bzdn\u00e9ho prachu. Paxi a Euclid se na sebe pod\u00edvali a jejich radost z\u00e1\u0159ila stejn\u011b jasn\u011b jako hv\u011bzdy kolem nich.<\/p>\n

\u201cPoj\u010fme d\u00e1l objevovat, Euklide! Kdo v\u00ed, jak\u00e9 dal\u0161\u00ed z\u00e1zraky je\u0161t\u011b najdeme?\u201d \u0159ekl Paxi a vzn\u00e1\u0161el se vedle dalekohledu.<\/p>\n

Euclid souhlasil. Ten state\u010dn\u00fd mal\u00fd dalekohled teprve za\u010d\u00ednal a spolu s Paxim se u\u017e nemohl do\u010dkat, a\u017e odhal\u00ed dal\u0161\u00ed tajemstv\u00ed vesm\u00edru!<\/p>\n

Paxi se brzy vr\u00e1t\u00ed s dal\u0161\u00edmi vzru\u0161uj\u00edc\u00edmi objevy, nov\u00fdmi ot\u00e1zkami k prozkoum\u00e1n\u00ed a \u00fa\u017easn\u00fdmi m\u00edsty, kter\u00e1 stoj\u00ed za to nav\u0161t\u00edvit. Do t\u00e9 doby se d\u00edvejte nahoru na hv\u011bzdy, z\u016fsta\u0148te zv\u011bdav\u00ed a nikdy nep\u0159est\u00e1vejte objevovat!<\/b><\/p>\n

Uvid\u00edme se brzy p\u0159i na\u0161\u00ed dal\u0161\u00ed misi \u2013 \u010dek\u00e1 na n\u00e1s cel\u00fd vesm\u00edr!<\/b><\/p>","protected":false},"excerpt":{"rendered":"
