Cabanga ukwazi ukuzinikezela ngokomsebenzi emhlabeni we i-astronomy, isayensi ethakazelisa kakhulu, njengoba kwenzekile kulo mcimbi, ingasinikeza ngendlela emangazayo yokwazi ukuthi kwenzekani ngaphandle kweplanethi yoMhlaba noma imane ikhombise ukuthi, kude nale planethi, izinto zingenzeka esingazange sizicabange nokukucabanga.
Lokhu yikho kanye okwenzekile eqenjini lezazi zezinkanyezi zaseJapan ezathi, ngenkathi zisebenzisa i- Isibonakude se-ALMA Kweminye imisebenzi nezifundo zesikhala, babekhethe ngqo ukubuka ukusebenza kwefu lamagesi anobuthi, babona ukuthi lokho abanakho phambi kwabo kwakungeyona into engaphansi kwalowo owabhapathizwa njenge imbobo yesibili ngobukhulu emnyama eMilky Way.
Ngenxa yomthamo we I-ALMA telescope ikwazile ukuthola lokho okuthiwa umgodi wesibili ngobukhulu omnyama eMilky Way
Qaphela ukuthi lo mgodi omkhulu omnyama ubungakatholakali kuze kube manje ngenxa ye- izindlela ezinomkhawulo lapho izazi zezinkanyezi zazibala khona. Ukuze uthole lo mgodi omnyama, noma ngabe mkhulu kangakanani, kuye kwadingeka ukuthi usebenzise okungekho ngaphansi kuka I-ALMA (Large Millimeter / submillimeter Array) isibonakude uhlelo yakhiwa ama-telescopes omsakazo angama-66 ebitholakala eSierra de Atacama (eChile).
Ngokwesitatimende esenziwe ngumkhulumeli waleli qembu lezazi zezinkanyezi zaseJapan, ngokusobala nangesikhathi sokuphenya babekwenza ifu lamagesi anobuthi, iqembu lososayensi laqaphela ukuthi ama-molecule asemafini ayehudulwa ngu- a amandla amakhulu adonsela phansi, okuthile okungachazwa kuphela ngokuba khona komgodi omnyama onendawo ezungezile ye- Amakhilomitha ayi-1.4 billion.
Akungabazeki, ucezu lolwazi olusinika okuningi okufanele sicabange ngakho njengoba imbobo emnyama yalezi zici, ngokusho kochwepheshe emkhakheni, kungaba kukhulu okuphindwe kayizinkulungwane eziyikhulu kuneLanga uqobo, iqiniso lokuthi, ngaphandle kokungabaza, lisisiza kancane ukuqonda ukuthi yiluphi uhlobo lomgodi omnyama esingahle sibhekane nawo, olungakatholakali kuze kube yizinsuku ezedlule, into esenza sicabange ngakho konke esingakwazi futhi uma kukhona ngaphezulu kwalezi zimbobo ezimnyama noma ezinye izinhlobo zezinto.
Bekungakakwazi ukuqinisekisa ukutholakala kwalo mgodi omnyama obabazekayo
Okwamanje, abacwaningi abaningi bazama ukubheka leli phuzu elithile esikhaleni ukuze babone ukuthi singaba yini phambi komgodi wesibili ngobukhulu owaziwa eMilky Way. Ngokuningiliziwe, sitshele ukuthi, ngokwamanye amaqembu abacwaningi, kubanjwe amagagasi omsakazo angakhombisa ukuthi kukhona imbobo emnyama maphakathi naleli fu elinobuthi nokuthi lokhu kungaba isisindo sokuqala esiphakathi esitholakala eMilky Way.
Sibhekene nokutholwa okusisondeza kancane kulolo lwazi olungeke lusisize siqonde ukuthi iMilky Way ingadalwa kanjani, hhayi ize, ososayensi banokusola ukuthi umgodi omnyama wakhiwa lapho ezinye izinkanyezi ziqhuma lapho 'ukufa'. Ngakolunye uhlangothi, kunososayensi abaningi ababheka ukuthi ukwakhiwa kwale mibobo emnyama emikhulu kwakhiwa lapho kuhlangana okuningi, ngaleyo ndlela kwakheka okukhudlwana noma, ngokusho kweminye imithombo, ngokuqongelela izinto ezivela engxenyeni yomthala ezungeze umgodi omnyama uqobo.
UTomoharu Oka yisazi sezinkanyezi esihola iqembu elithole ubukhona balo mgodi omnyama omkhulu
Ngokusho kwezitatimende ezenziwe okungekho ngaphansi kuka UTomoharu Oka, Isazi sezinkanyezi saseJapan esiphethe lolu cwaningo, ngokusobala lo mgodi omnyama obuzotholakala muva nje kungaba yiwo Umnyombo womthala omdala omfushane okwadliwa abantu ngesikhathi kwakhiwa iMilky Way izigidigidi zeminyaka eyedlule.
Ngokusho kukaTomoharu Oka, kubonakala esikhathini esizayo lo mgodi omnyama uzokhangwa yiSagittarius A, umgodi omnyama omkhulu kunayo yonke emthaleni wethu. Okwamanje lapho zombili izimbobo ezimnyama zihlangana, enkulu kakhulu futhi enkulu kakhulu izokwakhiwa. Okwamanje konke kuyizinkomba futhi, njengoba ososayensi beqinisekisa, akukaze kwenzeke ukuqinisekisa ukuthi okutholakele noma ukubaluleka kwangempela, yize lolu cwaningo luvule izindlela ezintsha zokuthola umsuka walezi zinto.
