I-Spaceship Earth: Ichashaza lothuli endaweni yonke.

I-Pale Blue Dot igama elilodwa Izithombe Zomhlaba, ezithathwe umkhumbi-mkhathi iVoyager 1 ebangeni elingamakhilomitha ayizigidi eziyizinkulungwane ezingu-6,4, okuyibanga elikhulu kunawo wonke okwake kwathathwa kuwo isithombe soMhlaba.

Lesi sithombe sathathwa ngoFebhuwari 14, 1990 njengengxenye yochungechunge lwezithombe ezingama-60 ezibonisa sonke isimiso sonozungezilanga esinamaplanethi ayisithupha abonakalayo.

Ngokusikisela kwesazi sezinkanyezi uCarl Sagan Ngemva kokuphothula izinjongo eziyinhloko zemishini, i-Voyager 1 yazukiswa ngamadigri angu-180 futhi yathwebula uchungechunge lwezithombe ze-telephoto ezingu-39 ezibanzi nezingu-21.

Ngesikhathi kuthathwa lesi sithombe, umkhumbi-mkhathi wawuqhele ngamakhilomitha ayizigidi eziyizinkulungwane ezingu-6 kuya kwezingu-7 ukusuka eLangeni nama-degree angu-32 ngaphezu kwe-ecliptic, ngakho wawubheka isimiso sonozungezilanga uphezulu.

Umhlaba uthwetshulwe ngekhamera ye-telephoto kusetshenziswa izihlungi zombala oluhlaza okwesibhakabhaka, oluhlaza okotshani kanye no-violet. Imisebe edlula esithombeni yenzeka njengokukhanya kwelanga kusakazeka kukhamera optic, njengoba yayingaklanyelwe ukuba iqondiswe elangeni ngokuqondile. Umhlaba uthatha kuphela u-12% wephikseli eyodwa.

Lesi sithombe sigqugquzele uSagan ukuthi abhale incwadi yakhe ethi “Blue Dot in Space. Umkhathi wethu wasekhaya". Ososayensi bavotele lesi sithombe ngesinye sezithombe eziyishumi ezihamba phambili kwisayensi yasemkhathini ngo-2001.

Ukudubula kwelanga okune-engeli ebanzi kuthathwe ngesihlungi esimnyama kakhulu kanye nesikhathi sokuchayeka esifushane kakhulu (5/1000th wesekhondi) ukuze kugwenywe ukuchayeka ngokweqile.

Ngesikhathi sokurekhoda, ilanga laliyi-1/40 kuphela ububanzi obubonakalayo njengoba bubonakala eMhlabeni. Nokho, isakhanya izikhathi eziyizigidi ezingu-8 kunenkanyezi egqame kakhulu, uSirius.

Ingozi yomuntu emkhathini Umhlaba - Umhlaba uyingcosana yothuli endaweni yonke

Umqondo we-Anthropocene ubeka abantu enkabeni yomlando womhlaba. Ingxoxo yenhlalo nemikhakha eyahlukene mayelana nalokhu ikhule kakhulu muva nje; kusibonisa ngokucacile amehloukuthi wonke umuntu ohlala emhlabeni uthatha umthwalo wemfanelo weplanethi. Ku-geological stratification okwamanje kukhona ngisho nenkulumo-mpikiswano mayelana nokufaka inkathi entsha ye-geological ebizwa ngokuthi i-Anthropocene ku-nomenclature esemthethweni yama-stratigraphers.
