Umfanekiso - iNASA
Izibane zaseMantla zezona zibalaseleyo kwindalo ebusika. Umboniso onokuthi amaKhanadi onwabele iiyure ezimbalwa emva kobusika kwaye loo nto I-NASA yathwebula umfanekiso kunye ne-night-night band » (DNB) yesixhobo sakho seVIIRS (I-Visual Infrared Imagin Radiometer Suite, okanye iRadiometer ye-Infrared Infrared eSpanish) yesathelayithi yeSuomi NPP.
I-DNB ifumanisa ukukhanya kokukhanya okufana ne-auroras, i-glare yomoya, i-gas flares, kunye nokukhanya kwenyanga. Ngelo thuba, wafumanisa aurora borealis "isaqhwithi" kumantla Canada.
Zenzeka njani iiurora?
Ii-auroras zizinto eziqhelekileyo ezibondeni, emantla nasezantsi. Xa zisenzeka kwipali esemazantsi, zaziwa njengeeurora zasemazantsi, kwaye xa zisenzeka kwipali esemantla, njengezibane ezisemantla. Zombini zenzeka xa umoya elanga ungqubana nomhlaba womazibuthe womhlaba. Ngokwenza njalo, amandla ayolulwa kwaye aqokelelwe ngaphakathi, de kube imigca yemagnethi yomhlaba iphinda idibane kwaye ngesiquphe iyikhuphe, iqhubela ii-elektronon ukuba zibuyele kwiplanethi.
Nje ukuba la masuntswana angqubane nenxalenye ephezulu yomoya ojikeleze umhlaba, oko sikubiza ngokuba yi-aurora kuveliswa, yiyo ke leyo ebangela ukuba isibhakabhaka seengingqi ezibandayo zibemibala.
Ividiyo yeeLight zaseNyakatho eCanada
Ngoku siyazi ukuba ziveliswa njani, masizonwabele. Singaba kude neepali, kodwa ubuncinci siza kuhlala sinazo iividiyo. Kwaye oku kuyamangalisa ngokwenene:
Abantu baseCanada babe, ngaphandle kwamathandabuzo, ukuqala kwelona xesha libandayo lonyaka weyona nto inemibala eqaqambileyo kwaye ayothusi, awucingi? Izibane zasemantla zitsala umdla omkhulu, kuba uyazi ukuba, ukuba unethamsanqa ukuzibona, eyona nto inokwenzeka kukuba baya kukumangalisa. Ukuhamba kwayo kunye nemibala yayo kubonakala ngathi ithathwe ephupheni, ethi, ngethamsanqa, ibe yinyani.
