Astronomii care folosesc Telescopul Spa\u021bial James Webb (JWST)<\/a> <\/span>au descoperit o \u201ecre\u0219\u0103\u201d stelar\u0103 enigmatic\u0103 \u00een apropierea centrului C\u0103ii Lactee, scrie Daily Galaxy<\/a><\/span>.<\/p>\n

Descoperirea pune sub semnul \u00eentreb\u0103rii teoriile cunoscute privind eficien\u021ba form\u0103rii stelelor \u00een medii galactice extreme.<\/p>\n

O regiune de formare stelar\u0103 neobi\u0219nuit de eficient\u0103<\/h2>\n

Regiunea, cunoscut\u0103 sub numele de Sagittarius B2, se afl\u0103 la aproximativ 26.000 de ani-lumin\u0103 de P\u0103m\u00e2nt, aproape de centrul galaxiei.<\/p>\n

De\u0219i con\u021bine doar circa zece la sut\u0103 din gazul molecular din zon\u0103, produce aproape jum\u0103tate din stelele care se formeaz\u0103 acolo.<\/p>\n

Oamenii de \u0219tiin\u021b\u0103 spun c\u0103 un asemenea nivel de eficien\u021b\u0103 contrazice modelele actuale de formare a stelelor.<\/p>\n

Cu ajutorul instrumentelor \u00een infraro\u0219u ale lui Webb, cercet\u0103torii au observat nori den\u0219i de gaz \u0219i praf care str\u0103lucesc \u00een nuan\u021be intense de ro\u0219u \u0219i violet.<\/p>\n

Unele regiuni r\u0103m\u00e2n complet opace, suger\u00e2nd existen\u021ba unor protostele ad\u00e2nc \u00eengropate, ascunse privirii.<\/p>\n

Un mediu chimic bogat \u0219i extrem<\/h2>\n

Datele din infraro\u0219u mediu au scos la iveal\u0103 zone cu o complexitate chimic\u0103 excep\u021bional\u0103 \u00een interiorul norului.<\/p>\n

Aceste regiuni con\u021bin molecule rareori \u00eent\u00e2lnite \u00eempreun\u0103 \u00een alte p\u0103r\u021bi ale galaxiei.<\/p>\n

Cercet\u0103torii cred c\u0103 turbulen\u021bele, c\u00e2mpurile magnetice \u0219i diferen\u021bele de temperatur\u0103 ar putea accelera colapsul gravita\u021bional.<\/p>\n

Totu\u0219i, nicio teorie singular\u0103 nu explic\u0103 pe deplin productivitatea extraordinar\u0103 a regiunii.<\/p>\n

Radia\u021bia intens\u0103 \u0219i gravita\u021bia puternic\u0103 din centrul galactic complic\u0103 \u0219i mai mult modelarea acestui mediu.<\/p>\n

Implica\u021bii pentru evolu\u021bia galactic\u0103<\/h2>\n

Oamenii de \u0219tiin\u021b\u0103 de la NASA afirm\u0103 c\u0103 \u00een\u021belegerea regiunii Sagittarius B2 ar putea remodela teoriile despre evolu\u021bia galaxiilor.<\/p>\n

Dac\u0103 astfel de \u201efabrici\u201d stelare extrem de eficiente sunt comune \u00een apropierea nucleelor galactice, modelele actuale ar putea necesita revizuiri.<\/p>\n

Observa\u021biile \u00een infraro\u0219u stratificate ale telescopului spa\u021bial James Webb<\/a><\/span> permit cartografierea simultan\u0103 a temperaturii, densit\u0103\u021bii \u0219i compozi\u021biei chimice.<\/p>\n

Datele sugereaz\u0103 c\u0103 mai multe genera\u021bii de stele se pot forma simultan \u00een acela\u0219i nor.<\/p>\n

Studiile viitoare vor stabili dac\u0103 Sagittarius B2 este un caz izolat sau parte a unui tipar cosmic mai larg.<\/p>\n","protected":false},"excerpt":{"rendered":"
