Kudala-dala kumnyele okude, kude lee, umngxuma omnyama omkhulu wakhupha umqondiso onamandla kanomathotholo, owahamba iminyaka eli-13 lamawaka ezigidi ukuya eMhlabeni. Le ayisiyo & apos; ayisiyonto yentsomi yesayensi- ziyinyani. Isebenzisa iTeleskopu eNkulu yaseYurophu (i-ESO & apos; s VLT) e-Chile, iqela labaphandi lifumanise ukuba yeyiphi na indalo kunye neepos;
Olu phawu lomzobi lubonisa ukuba i-quasar ekude P172 + 18 kunye neejets zayo zerediyo zinokujongeka njani. Olu phawu lomzobi lubonisa ukuba i-quasar ekude P172 + 18 kunye neejets zayo zerediyo zinokujongeka njani. Ukuza kuthi ga ngoku (ekuqaleni kowama-2021), le yeyona quasar ikude kakhulu ngeejethi zerediyo ezakha zafunyanwa kwaye yafundwa ngoncedo lweTeleskopu eNkulu kakhulu ye-ESO. Kukude kakhulu kangangokuba ukukhanya okukuyo kuye kwahamba malunga ne-13 yezigidigidi zeminyaka ukufikelela kuthi: sikubona njengokuba kwakunjalo xa i-Universe yayimalunga neminyaka engama-780 ezigidi ubudala. | Ityala: ESO / M. Umvavanyi
I-quasar yinto eqaqambe kakhulu yasezulwini efumaneka embindini we Umnyele Ixhaswe ngumngxunya omnyama osebenzayo, lowo utya imixholo ngeenxa zonke kuwo. (Uninzi lweminyele, kubandakanya eyethu iMilky Way, inemingxunya emnyama ezolileyo kumaziko abo.) Le quasar isandula ukufunyanwa, ebizwa ngokuba yi-P172 + 18, iyamangalisa: Umngxunya wayo omnyama ukhupha iintsalela zesidlo sazo ngohlobo lwamaza erediyo , okanye iijethi, nto leyo eyenze ukuba izazi ngeenkwenkwezi zibize 'unomathotholo omkhulu.' Ukuza kuthi ga ngoku, yi-10% kuphela yazo zonke ii-quasars ezaziwayo ezinomathotholo, kwaye i-P172 + 18 yeyona ikude kakhulu, kwi-13 yezigidigidi zeminyaka yokukhanya. Nangona thina & apos sifumene ii-quasars zide zaya kude, akukho namnye kubo onengxolo ephezulu.
Oososayensi bavuyiswa yile nto, njengoko umgama ukusuka eMhlabeni uthetha ubudala bayo-le quasar mhlawumbi yenzeke xa i-universe yayineminyaka engama-780 yezigidi ubudala ubudala. Ngokuthelekisa, indalo iphela iqikelelwa ukuba ineminyaka engama-13.8 yezigidi zeminyaka ikho namhlanje.
Ke, ngokufunda i-P172 + 18, izazinzulu zinakho ukufumana ukuqonda ngemvelaphi yayo, ke yonke into. 'Ndiyifumanisa inika umdla kakhulu ukufumanisa & iiapos; ezintsha & iiapos; imingxunya emnyama okokuqala, kunye nokubonelela ngesakhiwo esinye ukuqonda indawo yokuqala, apho sivela khona, kwaye ekugqibeleni thina, 'isazi ngeenkwenkwezi se-ESO uChiara Mazzucchelli, omnye wabaphandi abafumene ikhwaskari, utshilo ingxelo .
Yintoni ngakumbi, ukufumana i-P172 + 18 kuya kukhokelela ekufumaneni okufanayo kwee-quasar ezikude ngakumbi, ukubonelela ngolwazi olongezelelweyo kwizazi ngeenkwenkwezi ukuba zifunde. U-Eduardo Bañados, elinye ilungu leqela lophando, uthe, 'Oku kufunyanisiweyo kundenza ndibenethemba, kwaye ndiyakholelwa - kwaye ndinethemba - lokuba irekhodi lomgama liza kwaphulwa kungekudala.'
