Ilanga lemini kunye nokukhanya kothuli
Yintoni le? Iifestile zendlela, iinqanawa, izindlu kunye nemifanekiso ebonisa ukuba ilanga likhanya, kwaye eli kukhanya lifihla iiplanethi ezimnyama. Eli sixhobo sibonisa iiplanethi ezibonakalayo kwincwadi yemifanekiso yeplanethi kwaye inani elikhulu liphela njengoko ilanga likhanya, ukusuka kwindawo emnyama kwelinye icala ukuya kwisixeko esiphakathi.
Indlela yokusetyenziswa kwayo: Khetha inkcazelo ethetha kakhulu njengelanga lakho, okanye rhuqa umgca wokudada wokukhanya. Rhuqa imboniselo yelanga ukujonga ngaphaya.
Imnyama kangakanani izulu lakho?
Khetha enye ethetha njengelanga apho uhlala khona. Umfanekiso ngamnye ubonisa iinkwenkwezi ze Orion onokuthi uzibone kulo mgangatho.
Indawo ye-star kunye nokukhanya kwe-Yale Bright Star Catalogue. Indawo yakho ayigcinwanga.
Zama oku
- Qala kwinqanaba 1 (indawo emnyama ngokuqinisekileyo) kwaye urhoxise ngesantya ukuya kwi 9.Isaziso: Kuzo zonke iinkwenkwezi ezimalunga ne9000 ezijikeleze isibhakabhaka, ziyi-400 kuphela ezihlala kwisixeko esiphakathi, kwaye yinxalenye yesibhakabhaka kuphela engaphezulu kwakho nangaliphi na ixesha.
- Choose Orion and compare levels 4 and 8.Isaziso: Umfanekiso owaziwayo uhlala, kodwa iinkwenkwezi ezimnyama ezizigcwalisayo, kunye nendlela yemilky ecaleni kwayo, ziphela.
- On the next clear night without a Moon, go outside away from direct lights and wait 20 minutes for your eyes to adjust.Isaziso: Fumana umfanekiso apha othelekiswayo nobona: oko kufutshane nomphakamo wakho we Bortle. Imifanekiso ibonisa indawo ye Orion; nayiphi na iqela eliqhelekileyo leenkwenkwezi lisebenza.
Iimbono ezimva kwayo
Yintoni ongayikwenza?
Ukutshatyalaliswa kwelanga kukuxhaphaza okulula ukusombulula: shiya umbane kwaye kuyaphela. Nciphisa iinkuni zangaphandle uze uzikhusele, sebenzisa ii-bulbs ezinomthunzi opholileyo, kwaye uvale iinkuni ezingafunekiyo ngumntu wonke.
Iindawo zembali yelanga kunye nokukhanya ukusuka kwi Yale Bright Star Catalogue (uguqulelo lwe 5). Amanqanaba ezulu kunye neentyatyambo ezibonakalayo ezimnyama ukusuka ku J. E. Bortle, "Introducing the Bortle Dark- Sky Scale", Sky & Telescope, February 2001. Uncedo lokukhanya: DarkSky International. Indawo yakho ayizucelwa okanye igcinwa.
Artificial light that shines where it is not needed, especially up into the sky. It makes the whole night sky glow and hides the stars.
Okuninzi kwincwadi eneenkcukacha →Isikali se 1 ukuya kwi 9 sokuba ikhanya kangakanani na ilanga lemini, epapashwe ngu-amateur astronomer uJohn E. Bortle ngo 2001. Umphakamo we 1 yilanga elimnyama kakhulu emhlabeni; umphakamo we 9 yindawo esembindini womzi.
Okuninzi kwincwadi eneenkcukacha →Isikali aba astronomi besebenzisayo sokukhanya. Amanani amakhulu kuthetha akhanyayo: iinkwenkwezi ezikhanyayo zijikeleze ubukhulu 0 okanye 1, kwaye ezimnyama ozibonayo ukusuka kwindawo emnyama ngokuqinisekileyo zimalunga nobukhulu 7 ukuya ku 8.
Okuninzi kwincwadi eneenkcukacha →Amehlo akho aqala ukuba nefuthe elincinci xa emnyama. Kuthatha imizuzu engama-20 ukuya kwengama-30, kwaye ukujonga iscreen esikhanyayo okanye isibane selanga kwenza ukuba kukhulule kakhulu.

Izixhobo kunye neengcebiso zisebenzisa iimodeli ezilula zokufunda kuphela. Akufanele zisetyenziswe ukuqhuba, ucwangciso lwemikhosi okanye nayiphi na intlawulo yokusebenza. Iziqinisekiso azihlawulwanga kwaye azigunyaziswanga. Funda uxanduva lokungasebenzisi imixholo yoqeqesho
