El ALMA teresikopu Ichakurumidza kuve chimwe chezvombo chakashuiwa zvakanyanya nevose vanoongorora nyeredzi pasi pano nekuda kwesimba uye kugona kwayo. Kutenda chaizvo kune mikana inopihwa neichi chishandiso, boka revazivi venyeredzi rakakwanisa kuona okisijeni panzvimbo iri kure kwazvo yakatorwa kusvika pari zvino neteresikopu, mukadzi wechidiki renyeredzi A2744_YD4.
Chimwe chezvinhu zvikuru zveiyi gwara riri kure nderekuti, kushamisika kwevaongorori, rine yakawanda stardust, chimwe chinhu chingave chiri mhedzisiro yekufa kwechizvarwa chekutanga uye chepakutanga chizvarwa chenyeredzi. Iri guruva, zvakare, rinonyanya kuverengerwa nezvinhu zvakaita sesiliconi, kabhoni nealuminium, zvinhu zviripo mune zvidimbu zvidiki zvehukuru hwechuru chemiriyoni imwe.
Nicolas Laporte nechikwata chake vakawana ionized oxygen mugirazi A2744_YD4.
Sezvatsanangurwa Nicholas Laporte, muongorori paYunivhesiti yeLondon uye mukuru wechikwata chaita izvi kuwanikwa:
A2744_YD4 haisiriyo chete gwara rekupedzisira kusvika zvino rakacherechedzwa neALMA, asi kuwanikwa kweguruva rakawandisa kunoratidza kuti gwara iri rakanga ratosvibiswa neyakanyanya supernovae. Iyo iri mune inozivikanwa galaxy iyo yakatanga apo zvakasikwa zvaingova zvina muzana muzana yeiri razvino zera.
Ichi chidzidzo chakagonesa kuona kubwinya kunobuda kweionized okisijeni, yakavatendera ona renyeredzi sezvazvaive apo iyo cosmos yaive isingabude mamirioni mazana matanhatu emakore, iyo nguva iyo nyeredzi dzekutanga uye mapoka enyeredzi zvaigadzirwa. Zvinoenderana nekufungidzira kwakaitwa mushure mezvidzidzo, zvinoita sekunge iro giraidhi raizove neguruva rakaenzana nemamirioni matanhatu zvakapetwa kuwanda kweZuva.
