Total yelanga Ukusithwa kwelanga yinyanga kuya kubonwa kwilizwekazi laseMntla Melika ngoMvulo we-8th Epreli 2024. Ukuqala eMexico, iza kunqumla eUnited States ukusuka eTexas ukuya eMaine, iphele kunxweme lweAtlantiki yaseKhanada.
E-USA, ngelixa inxenye yelanga Ukusithwa kwelanga yinyanga kuya kwenzeka kulo lonke ilizwe, iyonke yelanga Ukusithwa kwelanga yinyanga kuya kuqala ngo-1:27 pm CDT e-Eagle Pass, eTexas, inqumle ngokunqamlezileyo kwilizwe liphela kwaye iphele malunga ne-3:33 pm EDT eLee, eMaine.
Indlela epheleleyo iya kuba malunga neekhilomitha ezili-115 ububanzi igubungela ummandla ohlala abantu abangaphezu kwezigidi ezingama-30.
Total yelanga Ukusithwa kwelanga yinyanga kwenzeka xa iNyanga isiza phakathi koMhlaba kunye neLanga lisitha iLanga ngokupheleleyo ukuba lingabonwa eMhlabeni. Sisiganeko esibalulekileyo seenkwenkwezi kwizazinzulu kunye nabaphandi ngezizathu ezininzi.
I-Corona, eyona ndawo ingaphandle ye-atmosfera yeLanga, inokubonwa eMhlabeni kuphela ngexesha lilonke yelanga Umnyama yiloo nto iziganeko zinika abaphandi ithuba lokufunda. Ngokungafaniyo nefotosphere, umaleko weLanga obushushu bawo bumalunga ne-6000 K, i-atmosphere engaphandle i-corona iba shushu ukuya kutsho kwizigidi zeedegrees Kelvin. Umjelo wamasuntswana atshajelwe ngombane uphuma kwicorona ukuya isithuba kuwo onke amacala (ebizwa yelanga umoya) kunye nokuhlamba konke maplanethi kwi yelanga inkqubo kuquka noMhlaba. Ibeka isoyikiso kuhlobo lobomi kunye nobuchwepheshe bombane obusekelwe kuluntu lwanamhlanje olubandakanya iisathelayithi, oosomajukujuku, ukuhamba ngenqanawa, unxibelelwano, ukuhamba ngomoya, iigridi zamandla ombane. Imagnethi yomhlaba ikhusela kwizinto ezingenayo yelanga moya ngokubaphambukisa. Ngokugqithisileyo yelanga Iziganeko ezifana nokukhutshelwa kweplasma etshajiweyo ngombane kwicorona kudala ukuphazamiseka kumoya welanga. Kungoko kufuneka kufundwe ngecorona, umoya welanga neziphazamiso kwiimeko zayo.
Ukusithwa kwelanga yinyanga ngokupheleleyo kunika ithuba lokuvavanya iithiyori zenzululwazi ngokunjalo. Omnye umzekelo weklasikhi kuqwalaselo lwelensi yomxhuzulane (oko kukuthi, ukugoba kwe Nkwenkwezi ukukhanya ngenxa yomxhuzulane wezinto ezinkulu zasesibhakabhakeni) ngexesha lokusithwa kwelanga yinyanga kwe-1919 ngaphezulu kwenkulungwane eyadlulayo nto leyo yaqinisekisa ubudlelwane obuqhelekileyo buka-Einstein.
Isibhakabhaka sitshintshile ngokukhawuleza ngenxa yokuthengiswa kwe-Low Earth IiOrbits (LEO). Kukho malunga ne-10,000 yesathelayithi kwi ukuhamba ngoku, ngaba oku kusithwa kwelanga yinyanga kutyhila isibhakabhaka esizele ziisathelayithi? Uphononongo lwakutsha nje lokulinganisa lucebisa ukuba ukukhanya kwesibhakabhaka okuphezulu ngexesha elipheleleyo kuya kwenza ezona satellite ziqaqambileyo zingabonakali kwiliso elingenanto kodwa ukukhazimla okuvela kwizinto ezenziweyo ngaphakathi. ukuhamba isengabonakala.
