Inkqubo yokukhanya

Kwiminyaka emakhulu amawaka, yonke into yobuntu bomuntu ojonge phezulu ngobusuku obucacileyo wabona into efanayo: amawaka ee-inkwenkwezi nomlambo omdaka wendlela ye-milk. Yazibeka iikhalenda, ukuqhubela phambili, amadini kunye nesayensi. Kwixesha elinye lokuphila sifihle ngaphambili i-dome ekhanyayo yelanga elilahlekileyo. Inkqubo yokukhanya ikhona ukubuyisela le nto, kwaye le yingxaki enye yendalo enokuthi ilungiswe ngobusuku xa ugqiba ekulungiseni.

Ilanga lasemini ngamanani

Ngokutsho kwe-atlas yehlabathi yokukhanya kwesibhakabhaka esiyenziweyo, iepesenti ezingama-80 zabantu behlabathi, kunye ne iepesenti ezingama-99 zabantu eMelika naseYuropu, baphila phantsi kweendawo ezikhanyayo ezityheliweyo. Onye kwiintlanu abantu emhlabeni abakwazi ukuqhubeka nokubona iNkqubo yeMnyama ukusuka apho bahlala khona. Kwaye iqhubeka ikhula: amawaka ambalwa eesayensi zamazwe ngamazwe ezibala ii-stars zifumanisa ukuba isibhakabhaka sakusasa sikhanya ngomhlathi we 9.6% ngonyaka phakathi kuka-2011 no-2022, ephindaphindwe ukukhanya kwelanga kwiminyaka emihlanu.

Iinkcukacha

Ngokungafani negesi yeglasi eluhlaza, uthuli olukhanyayo alunakukhutshwa. Vala, khusela okanye ucofe ilanga kwaye ubumnyama bubuyela ngokukhawuleza. Iindlela zokulungisa zibiza phantsi, zifumaneka kuwo onke amashishini ezixhobo zekhompyutha kwaye zihlala zigcina imali kwi-umbane. Imimandla yonke, iziqithi kunye neendawo zokutyela ezijikeleze ihlabathi ziye zavela zibe yindawo eziqinisekisiweyo zezulu elimnyama ngokutshintsha ii-lights zabo.

Ukukhanya kokutshaya kukutywina kuphela okususwayo xa utshixa isixhobo.

Izinto eziluncedo

Ichaza uthuli olukhanyayo kunye nefuthe lalo ngolimi olucacileyo: bona uthini uthuli olukhanyayo.
Ibonisa indlela yokuyilungisa ngayo, ngemiyalelo esebenzayo yasekhaya, yeshishini kunye nedolophu: bona ukukhanya kwangaphandle ngokuzimeleyo.
Idibanisa izulu nokufunda. I-Ofisi inkqubo yokufunda ngeendawo iqala ngezulu ngasentla kwakho.
Inkxaso yemisebenzi yangaphakathi, ezinjengeemini ezimnyama zesibhakabhaka, ukubala kweenkwenkwezi kunye nonxibelelwano neekomiti, ezicwangciswe ngabacebisi ibhodi.

Imnyama kangakanani izulu lakho?

I Imaphu Yokutshatyalaliswa Kwelanga ngu Jurij Stare ibonisa ukukhanya kwelanga okuzenzekelayo naphi na kwihlabathi, ngokusekelwe kwi data yesatellite. Iprojekthi yesayensi yobuhlanga Iglobhu ngobusuku ivumela wonke umntu ukuba alinganise isibhakabhaka sakhe ngaphandle kokwenza ntoni na ngaphandle kwamazinyo akhe, kwaye idibanisa ubalo lwakho kwirekhodi lehlabathi.

IYuropu, iAfrika neMpuma-Mphakathi ngobusuku obubonakaliyo ukusuka kwindawo engaphandle kwelanga, ngeemitha zesixeko ezibophelelayo phantsi kolwandle kunye nemilambo. — IYuropu, iAfrika neMpuma-Mzantsi ngobusuku, zidityanisiwe kwidatha eqoqwe yiSatellite Suomi NPP ngoAprili noOkthobha 2012. Imifanekiso yesatellite njengele yizinto eziphambili zemaphu yokukhanya kokutshabalalisa: yonke indawo ekhanyayo ikhanya eyaphuma phezulu. Ityala: NASA I-Earth Observatory, ikhaya lasekhaya

Uncedo olufumanekayo

Bala iinkwenkwezi zakho. Yiba ngumdlali kwiGlobe ngobusuku amaxesha amaninzi ngonyaka; ukujonga kwakho kwenziwa ibe yidatha.
Lungisa iinkwenkwezi zakho kuqala: zikhusele, zibonise ezantsi, zifudumeze, zimnyama kwaye uzibeke kwixesha okanye kwisixhobo sokubona intshukumo.
Xelelane nabahlobo bakho. Iilanga ezikhanyayo zihlala zisebenza ngenxa yesiqhelo, hayi ngenxa yobungozi. Unxibelelwano olunomtsalane kunye nencwadi eneenkcukacha ngale phepha lisebenza rhoqo.
Writen to your council. Buza inkqubo yokukhanya enesikhuselo esipheleleyo, ubushushu bombala oshushu be-3000 K okanye ngaphantsi, ukuvala emva kwemini ephakathi, kunye nokhuseleko lwelanga elimnyama kwiindawo zokutyela.
Cinga iinkampani ukuba zivale izibonakaliso kunye neefestile zendawo yokupaka imoto emva kokuvala.
I-host a star party. Isixhobo sokujonga phezulu ngobusuku obumnyama sitshintsha ingqondo ngokukhawuleza kunanoma yiyiphi isalathisi. Qala enye nge ibhodi yonikezelo.
