O planet\u0103<\/a> extrem\u0103, aflat\u0103 la 280 de ani-lumin\u0103 de P\u0103m\u00e2nt, pune sub semnul \u00eentreb\u0103rii unele dintre cele mai solide teorii ale astronomiei moderne.<\/p>\n

Descoperit\u0103 ini\u021bial \u00een 2021 de telescopul spa\u021bial TESS al NASA \u0219i analizat\u0103 ulterior cu ajutorul Telescopului Spa\u021bial James Webb, planeta TOI-561 b continu\u0103 s\u0103 uimeasc\u0103 comunitatea \u0219tiin\u021bific\u0103.<\/p>\n

Cercet\u0103torii o descriu drept o \u201ebil\u0103 de lav\u0103 umed\u0103\u201d, un termen care surprinde natura sa paradoxal\u0103: o lume dominat\u0103 de oceane de roc\u0103 topit\u0103, dar care, \u00een mod nea\u0219teptat, reu\u0219e\u0219te s\u0103 \u00ee\u0219i p\u0103streze o atmosfer\u0103 dens\u0103.<\/p>\n

O planet\u0103 care contrazice toate ipotezele<\/strong><\/h2>\n

TOI-561 b este un a\u0219a-numit \u201esuper-P\u0103m\u00e2nt\u201d, o planet\u0103 st\u00e2ncoas\u0103, mai mare dec\u00e2t Terra.<\/p>\n

La suprafa\u021b\u0103, temperaturile ating aproximativ 1.800 de grade Celsius, suficient pentru a men\u021bine roci \u00een stare lichid\u0103.<\/p>\n

\u00cen mod tradi\u021bional, oamenii de \u0219tiin\u021b\u0103 au considerat c\u0103 astfel de condi\u021bii extreme ar face imposibil\u0103 existen\u021ba unei atmosfere stabile.<\/p>\n

Observa\u021biile recente contrazic \u00eens\u0103 aceast\u0103 ipotez\u0103.<\/p>\n

Datele colectate de Telescopul James Webb indic\u0103 prezen\u021ba unei atmosfere relativ groase, care con\u021bine vapori de ap\u0103, oxigen \u0219i dioxid de carbon.<\/p>\n

\u201eAm fi crezut, pe baza cuno\u0219tin\u021belor noastre actuale, c\u0103 o planet\u0103 at\u00e2t de mic\u0103 \u0219i fierbinte nu ar putea s\u0103-\u0219i men\u021bin\u0103 atmosfera mult timp. Cu toate acestea, observa\u021biile arat\u0103 contrariul\u201d, a explicat cercet\u0103toarea Nicole Wallak.<\/p>\n

Echilibrul dintre lav\u0103 \u0219i atmosfer\u0103<\/strong><\/h2>\n

Explica\u021bia posibil\u0103 pentru acest fenomen neobi\u0219nuit ar putea sta \u00een interac\u021biunea dintre suprafa\u021ba planetei \u0219i atmosfera sa.<\/p>\n

Potrivit cercet\u0103torilor, exist\u0103 un echilibru dinamic \u00eentre oceanul de magm\u0103 \u0219i gazele atmosferice.<\/p>\n

Pe m\u0103sur\u0103 ce gazele sunt eliberate din interiorul planetei, lava le reabsoarbe, cre\u00e2nd un ciclu continuu care stabilizeaz\u0103 atmosfera.<\/p>\n

Acest mecanism ar putea explica modul \u00een care TOI-561 b reu\u0219e\u0219te s\u0103 \u00ee\u0219i p\u0103streze \u00eenveli\u0219ul gazos \u00een condi\u021bii extreme.<\/p>\n

Un an dureaz\u0103 mai pu\u021bin de 11 ore<\/strong><\/h2>\n

Planeta orbiteaz\u0103 extrem de aproape de steaua sa, la doar un sfert din distan\u021ba la care Mercur se afl\u0103 fa\u021b\u0103 de Soare.<\/p>\n

Din acest motiv, un an pe TOI-561 b dureaz\u0103 mai pu\u021bin de 11 ore.<\/p>\n

Aceast\u0103 apropiere determin\u0103 \u0219i un alt fenomen spectaculos: planeta este blocat\u0103 gravita\u021bional, astfel \u00eenc\u00e2t o parte a sa este permanent expus\u0103 luminii stelei, \u00een timp ce cealalt\u0103 r\u0103m\u00e2ne \u00een \u00eentuneric.<\/p>\n

Cu toate acestea, atmosfera pare s\u0103 distribuie c\u0103ldura suficient de eficient \u00eenc\u00e2t partea nocturn\u0103 s\u0103 nu fie complet \u00eenghe\u021bat\u0103.<\/p>\n

O relicv\u0103 din universul timpuriu<\/strong><\/h2>\n

TOI-561 b se afl\u0103 la aproximativ 560 de ani-lumin\u0103 de P\u0103m\u00e2nt \u0219i orbiteaz\u0103 o stea veche de circa 10 miliarde de ani \u2014 de dou\u0103 ori mai veche dec\u00e2t Soarele nostru.<\/p>\n

Aceast\u0103 caracteristic\u0103 sugereaz\u0103 c\u0103 planeta s-a format \u00eentr-o etap\u0103 timpurie a universului.<\/p>\n

Descoperirea sa ofer\u0103 indicii valoroase despre modul \u00een care s-au format primele planete st\u00e2ncoase \u0219i ridic\u0103 \u00eentreb\u0103ri fundamentale despre evolu\u021bia sistemelor planetare.<\/p>\n

O provocare pentru \u0219tiin\u021b\u0103<\/strong><\/h2>\n

Existen\u021ba acestei lumi extreme oblig\u0103 cercet\u0103torii s\u0103 reg\u00e2ndeasc\u0103 teoriile despre atmosferele planetare \u0219i limitele supravie\u021buirii acestora.<\/p>\n

TOI-561 b nu este doar o curiozitate cosmic\u0103, ci un exemplu clar c\u0103 universul este mai complex \u0219i mai surprinz\u0103tor dec\u00e2t pot explica pe deplin modelele actuale.<\/p>\n","protected":false},"excerpt":{"rendered":"
