Sinokubona iminyele embalwa ekude esibhakabhakeni ebusuku ngamehlo ethu, kodwa enye ekunzima ukuyibona, ngelishwa, yeyethu. IMilky Way ngumbono owoyikekayo kubusuku obumnyama, kodwa ngenxa yabantu kunye nokukhanya kwethu okungekuko, phantse akukho mntu eMntla Melika ufumana ubumnyama obaneleyo bokubona kwakhona.
Oko kuhambelana neatlasi entsha yongcoliseko lokukhanya okwenziweyo kwihlabathi liphela ipapashwe ngo Ukuqhubela phambili kwezeNzululwazi . Iitshathi zibandakanya ukubonisa ukuba kubalulekile wonke umntu kwisiqingatha sempuma ye-United States unenqanaba elibonakalayo longcoliseko lokukhanya , Ngesiqingatha esentshona sibonelela isibhakabhaka esikhanyayo ubukhulu becala de ufike kwizixeko zonxweme olusentshona. (Inqaku lokonwaba: Kumnyama ngokwaneleyo ukubona iMilky Way eMontanauk, NY ngexesha elingaphandle, apho ndayibonisa khona umntu owayekade ekholelwa ukuba yonke imifanekiso yayo yayiyinyani.)
Nangona kunjalo, ukuphoswa nguloo mbono — njengowesithathu kubemi behlabathi xa bebonke — awugubungeli konke ukungcoliswa kokukhanya okusehlabathini. Iatlasi ithi ama-99% aseMelika kunye nabemi baseYurophu bahlala phantsi kwesibhakabhaka esingcolileyo kancinci. Ezinye iindawo, njengeSingapore, ziqaqambile kangangokuba amehlo abantu awahambelani kakuhle nombono wasebusuku. Ungcoliseko lokukhanya alunabungozi ngokwenene ngaphandle kokuthintela umbono wethu wezendalo, kodwa luya kunyuka kuphela njengoko umhlaba uya usiba ninzi.
UCheryl Ann Bishop, uMlawuli wezoNxibelelwano we-International Dark-Sky Association uxelele ungcoliseko-mbuso, uxelele i-NPR, Inyaniso yokuba sihlamba iplanethi yethu ekukhanyeni okungeyonyani ebusuku yinto entsha, kwaye ngokuyintloko ifana nolingo lomntu siqala nje ukuqonda ubungakanani be-. Wongeze ukuba iindidi ezahlukeneyo zeebhalbhu kunye nezibane ezikhanyayo zichaphazela ukukhanya okubaleka esibhakabhakeni, ngezibane ze-LED ezinobume bendalo ngelishwa ngomnye waboni abaphambili.
Izinto ziye zanda ngakumbi ukususela ekuqaleni I-Atlas yeHlabathi yokukhanya kwesibhakabhaka ebusuku yenziwe, kwaye abanakulunga kwixesha elizayo. Okwangoku, iMilky Way ngumbono onqabileyo, kodwa abanye baqinisekile ukuba bayalandela-okanye sele benayo, kuxhomekeke kwindawo ohlala kuyo. Yonke le nto uyithethayo: Xa kukho into ecocekileyo ukuyijonga esibhakabhakeni ebonakalayo apho uhlala khona, phumela phandle uyixabise.
