\nAstronomii au descoperit o structur\u0103 misterioas\u0103, denumit\u0103 \u201etunel interstelar\u201d, \u00een vecin\u0103tatea sistemului nostru solar, parte dintr-o regiune anormal de fierbinte \u015fi de joas\u0103 densitate a galaxiei numit\u0103 \u201eBula Local\u0103 Fierbinte\u201d (LHB).<\/p>\n
\nAceasta ar putea conecta Sistemul Solar cu alte regiuni de densitate sc\u0103zut\u0103, indic\u00e2nd posibile leg\u0103turi \u00eentre \u201ebule fierbin\u0163i\u201d din galaxie.<\/p>\n
\nUtiliz\u00e2nd telescopul eROSITA, echipa condus\u0103 de astrofizicianul Michael Yeung de la Institutul Max Planck a realizat o hart\u0103 detaliat\u0103 a LHB. Ei au constatat c\u0103 bula are o form\u0103 asimetric\u0103, cu o expansiune mai pronun\u0163at\u0103 perpendicular pe planul galactic, fiind consistent\u0103 cu teoria c\u0103 structura a fost creat\u0103 de explozii de supernove care au avut loc \u00een zon\u0103 acum circa 14 milioane de ani.<\/p>\n
\nDe\u015fi bula are o temperatur\u0103 extrem de ridicat\u0103 de aproximativ un milion de grade Kelvin, acest lucru nu afecteaz\u0103 semnificativ materia din interiorul ei, densitatea fiind foarte sc\u0103zut\u0103. Totodat\u0103, structura emite radia\u0163ii X, permi\u0163\u00e2nd cartografierea acesteia.<\/p>\n
\nTunelul descoperit, orientat c\u0103tre constela\u0163ia Centaurus, ar putea conecta bula cu alte regiuni similare, incluz\u00e2nd nebuloasa Gum \u015fi mai multe nori moleculari.<\/p>\n
\nDescoperirea sus\u0163ine ipoteza c\u0103 galaxia ar putea avea o re\u0163ea de \u201ebule fierbin\u0163i\u201d interconectate, idee propus\u0103 \u00een 1974, dar pentru care dovezile au fost limitate.<\/p>\n","protected":false},"excerpt":{"rendered":"
