Lo ngumfanekiso-nangona kusenokwenzeka ukuba ayingowombala owaziyo ukuba uvula zonke iziqendu ze ICosmos: I-Spacetime Odyssey - ye-Helix Nebula, i-nebula yesijikelezi-langa esaziwayo ekufuphi kwi-constellation ye-Aquarius kwaye ijongeka njengeLiso elikhulu likaThixo kwii-engile ezithile. Owu, kananjalo? Inokukunceda ukwenza amanzi kwindalo iphela. Kuyabonakala ukuba olo luhlobo lwento enokuthi yenziwe ngamafu asemajukujukwini afayo ngamanye amaxesha.
Ngokophando lwakutsha nje olukhokelwe yiIYunivesithi yaseLeiden eNetherlandsImitha yelanga ekhoyo kwiiplanethi ze-nebulae ezigqitha kumaqondo obushushu ayi-100 000 ngokukaCelsius kunokuba negalelo ekwenziweniI-OH +, imolekyuli ehlawuliswe ngokuqinisekileyo eyenziwe ngeoksijini kunye nehydrogen eyimfuneko ekwakhiweni kweH2O.
Isifundo, esasikho Kutshanje kupapashwe kwi I-Astronomy kunye Astrophysics kwaye ungqinwe ngu hlukanisa isifundo esithile sikaHelix-nebula kwakule jenali , ikwacebisa ukuba iHelix Nebula yenye yezo OH + zivelisa i-nebulae yeeplanethi, kuba iyatshisa kwi-120,000 degrees Celsius.
Inkwenkwezi emhlophe eswelekileyo emhlophe embindini we-nebula ivelisa uthuli kunye negesi, kubandakanya icarbon monoxide. Izazi ngeenkwenkwezi zikholelwa ekubeni xa icarbon monoxide ibethwa yimitha yelanga, iphulukana nemolekyuli yeoksijini – ethi ke yona ikhululeke ukubopha ngeemolekyuli zehydrogen nazo ezifumaneka eluthulini, isifundo sesibiniIZiko leMfundo yezeNzululwazi yaseMadridamanqaku.
Sicinga ukuba umkhondo obalulekileyo ubukho bezixineneyo zerhasi nothuli, ezikhanyiswa yimitha ye-UV kunye ne-X-ray ekhutshwa yinkwenkwezi eshushu esembindini, utshilo u-Isabel Aleman weYunivesithi yaseLeiden kwingxelo evela Uqwalaselo lwe-ESA Hershel Space . Le radiation ene-eneji ephezulu inxibelelana neziqhushumbo ukubangela ukusabela kweekhemikhali okukhokelela ekwakheni iimolekyuli.
I-GIF engezantsi ibonise ubungakanani kunye nokuqina kwemveliso ye-OH + kwi-nebula:
Izazinzulu zezi zifundo zombini zivakalelwa kukuba olu lwazi lutsha linyathelo lokuqala elifanelekileyo lokuqonda ukuba iinkwenkwezi ezifa njengeHelix nebula zinokuba negalelo njani ekwakhiweni kwamanzi kwindalo iphela. Nangona kunjalo, abakacaphuli baphakamise ukuba zeziphi iimeko eziyimfuneko kolu lwakhiwo. Ngaba sicebisa ukuba sihlale phantsi i-nebulae kwaye sibenze babukele into ebuhlungu kakhulu, njenge Ibali lezinto zokudlala 3 okanye loo ndawo eneArtax in Ibali lokuThengisa ? Oko kuyakukwenzela i-H20, ngokuqinisekileyo.
