Umbono wegcisa lesithuba esitsha se-Horizons, yomhla ka-2015.Uvimba weMbali yeMbali / yeLifa leMifanekiso ngeGetty Images Uyakhumbula umfanekiso omfutshane osondeleyo wePluto okhanyise i-intanethi ngo-2015? Isiphekepheke esithatha lo mfanekiso, iphenyo ye-NASA ye-Horizons entsha, yenza nje enye into efumanekayo, ngeli xesha malunga nenyaniso enzulu yendalo iphela: ukuba kunokwenzeka ukuba kuninzi kakhulu iminyele esibhakabhakeni kunokuba besicinga ngaphambili, okuthetha ukuba lithuba lethu kwiiplanethi ezifana noMhlaba. kunye nobomi obungaphandle komhlaba, nabo buye bancipha.
Kudala izazinzulu zikholelwa ekubeni kukho iminyele engamawaka ezigidi ezibini kwindalo ebonakalayo, esekwe kwidatha evela kwiHubble Space Telescope. Kodwa idatha entsha ebuyiswe yi-New Horizons probe, eyayikumawaka ezigidi ezine ukusuka eMhlabeni xa kuthathwa umbono, iphakamisa ukuba umda ophezulu wenani leminyele iwela kumakhulu amawaka ezigidi, ngokwe ukufunda thaca kwiAmerican Astronomical Society kule veki.
Linani elibalulekileyo ekufuneka ulazi — mingaphi iminyele ekhoyo? Asikuboni ukukhanya kwiminyele engamawaka ezigidi ezibini, umbhali ophambili wesifundo, uMarc Postman we-Space Telescope Science Institute eBaltimore, Maryland, utshilo ingxelo .

Ukuze kuqikelelwe inani leminyele kwindalo iphela, izazinzulu ziqala ngokubala yonke into ebonakalayo kumhlaba onzulu weHubble kwaye ziphindaphindwe ngomhlaba opheleleyo wesibhakabhaka. Emva koko, ukuphendula ngeminyele ekude ethe tyaba kakhulu ukuba ingabonwa yiteleskopu, izazi ngeenkwenkwezi zifunda ngemvelaphi yokukhanya ebuthathaka abayiphosa emajukujukwini. Ukulinganisa oko kukhanya, iziphekepheke kufuneka zithunyelwe ngaphaya kwenkqubo yangaphakathi yelanga ukunqanda ungcoliseko lokukhanya olubangelwa lilanga elibonisa uthuli.
IiHorizons ezintsha yindawo yokuqala yophando eyakwaziyo ukulinganisa ukuqaqamba kwale cosmic optical yangasemva. Ukusuka ngaphandle kwenkqubo yelanga, iprosesa inokujonga isibhakabhaka esijikeleze kalishumi mnyama kunesibhakabhaka esimnyama esifikeleleka kuHubble.
Ezi ntlobo zemilinganiselo zinzima ngokugqithisileyo. Abantu abaninzi bazamile ukuyenza le nto ixesha elide. IiHorizons ezintsha zisibonelele ngendawo yokulinganisa ubungakanani bemvelaphi ye-cosmic ngcono kunaye nabani na okwazileyo ukuyenza, utshilo uTod Lauer weNOIRLab ye-NSF, omnye umbhali ophambili kolu phando. Thatha yonke iminyele ayibonayo uHubble, liphindaphinde elo nani, kwaye yile nto siyibonayo-kodwa akukho nto iyenye.
I-NASA iphehlelele i-New Horizons mission ngo-2006 ngeenjongo ezimbini eziphambili: ukufunda uPluto kunye neKuiper Belt. Iprojekhthi yabhabha ngempumelelo ngo-Pluto ngo-2015 kwaye yafota ifoto enezisombululo eziphezulu kwiplanethi yemithi okokuqala ngqa. NgoJanuwari 2019, yafumanisa into yeKuiper Belt ebizwa ngokuba yiArrokoth.
Isiphekepheke seNew Horizons ngoku singama-4.4 ezigidi zeebhiliyoni ukusuka eMhlabeni.
