O imagine realizat\u0103 de Telescopul Spa\u021bial Hubble dezv\u0103luie o regiune vast\u0103 \u00een care stelele se formeaz\u0103 activ, mult dincolo de galaxia noastr\u0103, scrie SciTechDaily<\/a><\/span>.<\/p>\n

Observa\u021bia se concentreaz\u0103 asupra N159, un nor dens de hidrogen rece situat la aproximativ 160.000 de ani-lumin\u0103 de P\u0103m\u00e2nt, oferind astronomilor o perspectiv\u0103 extrem de detaliat\u0103 asupra na\u0219terii stelelor.<\/p>\n

O regiune masiv\u0103 de formare stelar\u0103 \u00een apropierea C\u0103ii Lactee<\/h2>\n

N159 se afl\u0103 \u00een Marele Nor al lui Magellan (Large Magellanic Cloud), o galaxie pitic\u0103 aflat\u0103 \u00een vecin\u0103tatea C\u0103ii Lactee.<\/p>\n

Datorit\u0103 acestei proximit\u0103\u021bi, oamenii de \u0219tiin\u021b\u0103 pot studia mai u\u0219or procesele de formare stelar\u0103, comparativ cu galaxiile mai \u00eendep\u0103rtate.<\/p>\n

\u00centregul complex N159 se \u00eentinde pe mai mult de 150 de ani-lumin\u0103, de\u0219i imaginea surprins\u0103 de Hubble prezint\u0103 doar o parte din acesta.<\/p>\n

Dimensiunile uria\u0219e explic\u0103 modul \u00een care astfel de regiuni pot produce genera\u021bii \u00eentregi de stele pe parcursul a milioane de ani.<\/p>\n

Cum iau na\u0219tere stelele din gazul rece<\/h2>\n

\u00cen interiorul norului, temperaturile scad drastic, iar gravita\u021bia comprim\u0103 lent gazul de hidrogen \u00een aglomer\u0103ri tot mai dense.<\/p>\n

Pe m\u0103sur\u0103 ce aceste nuclee se contract\u0103, fuziunea nuclear\u0103 se aprinde, marc\u00e2nd na\u0219terea unor stele noi, \u00eenc\u0103 \u00eenv\u0103luite \u00een materialul care le-a creat.<\/p>\n

Cele mai masive stele tinere emit radia\u021bii intense, care activeaz\u0103 gazul de hidrogen din jur, f\u0103c\u00e2ndu-l s\u0103 str\u0103luceasc\u0103 \u00een ro\u0219u.<\/p>\n

Sensibilitatea telescopului Hubble la aceast\u0103 lungime de und\u0103 le permite astronomilor s\u0103 identifice zonele cu cea mai intens\u0103 activitate de formare stelar\u0103.<\/p>\n

V\u00e2nturile stelare creeaz\u0103 bule cosmice uria\u0219e<\/h2>\n

Unele stele nou-n\u0103scute par \u00eenconjurate de un gaz luminos, \u00een timp ce altele se afl\u0103 \u00een cavit\u0103\u021bi mari \u0219i goale, asem\u0103n\u0103toare unor bule.<\/p>\n

Aceste structuri apar \u00een urma unui proces numit \u201efeedback stelar\u201d, alimentat de radia\u021bii puternice \u0219i v\u00e2nturi stelare rapide.<\/p>\n

\u00cen timp, acest feedback remodeleaz\u0103 norul, cur\u0103\u021b\u00e2nd gazul din anumite zone \u0219i put\u00e2nd declan\u0219a formarea de noi stele \u00een altele.<\/p>\n","protected":false},"excerpt":{"rendered":"
