La fel ca fiin\u021bele vii, stelele \u00eemb\u0103tr\u00e2nesc \u0219i mor. \u00cens\u0103 stelele masive nu se sting \u00een lini\u0219te. Dimpotriv\u0103, ele \u00ee\u0219i \u00eencheie existen\u021ba cu o explozie uria\u0219\u0103. Tot ce r\u0103m\u00e2ne dup\u0103 spectacolul str\u0103lucitor al unei explozii de supernov\u0103 este un \u00eenveli\u0219 fierbinte \u0219i str\u0103lucitor de gaz care p\u0103r\u0103se\u0219te locul mor\u021bii stelei cu vitez\u0103 mare.<\/p>\n<\/div>\n

Unul dintre cele mai frumoase exemple de r\u0103m\u0103\u0219i\u021be de supernov\u0103 este Nebuloasa Voalului, un inel slab vizibil format din resturi, situat \u00een constela\u021bia Lebedei. Imaginile realizate cu ajutorul Telescopului Spa\u021bial Hubble al NASA-ESA arat\u0103 cu un nivel remarcabil de detaliu r\u0103m\u0103\u0219i\u021bele sf\u0103r\u00e2mate ale unei stele gigantice. Tot ce a mai r\u0103mas sunt ni\u0219te f\u00e2\u0219ii de gaz asem\u0103n\u0103toare fumului.<\/p>\n

Imaginile realizate de telescopul Hubble arat\u0103 filamente de gaz \u00eentre\u021besute, asem\u0103n\u0103toare unor fr\u00e2nghii, \u00een trei segmente diferite ale Nebuloasei Voalului. Filamentele colorate sunt rezultatul energiei uria\u0219e eliberate atunci c\u00e2nd resturile expulzate cu vitez\u0103 mare \u00een urma exploziei se ciocnesc de mediul \u00eenconjur\u0103tor. Undele de \u0219oc, generate de gazul care se deplaseaz\u0103 cu o vitez\u0103 de 600.000 km pe or\u0103, \u00eenc\u0103lzesc gazul la milioane de grade.<\/p>\n

\u00cen imaginile telescopului Hubble se disting dou\u0103 caracteristici: filamente liniare, bine conturate, \u0219i nori \u00eentin\u0219i. Acest lucru se datoreaz\u0103 faptului c\u0103 le observ\u0103m din unghiuri diferite. Filamentele corespund unei perspective laterale a unui front de \u0219oc sub\u021bire, \u00een timp ce norii corespund unei perspective frontale. Culorile indic\u0103 lumina provenit\u0103 de la diferi\u021bi atomi excita\u021bi de undele de \u0219oc: albastrul indic\u0103 oxigenul, verdele indic\u0103 sulful, iar ro\u0219ul indic\u0103 hidrogenul.<\/p>\n

Explozia supernovei a avut loc cu 5.000 p\u00e2n\u0103 la 10.000 de ani \u00een urm\u0103, c\u00e2nd str\u0103mo\u0219ii no\u0219tri ar fi observat o cre\u0219tere brusc\u0103 a str\u0103lucirii stelei, p\u00e2n\u0103 c\u00e2nd aceasta a ajuns s\u0103 aib\u0103 aceea\u0219i str\u0103lucire ca semiluna.<\/p>","protected":false},"excerpt":{"rendered":"
