Ubusuku obuhle kakhulu bokuzibona buzoba kusasa, ubusuku bango-12 kuya ku-13.Kodwa uma abanye abangenasineke bekwazi ukulinda noma bamane nje ngeke bakwazi kusasa, kulobubusuku bazokwazi nokubonana. Yazi, isiqongo kusasa! Umbukwane impela ukubona ukuthi zihlakazeka kanjani emkhathini, ibanga elingu-100km.
Sizokutshela amathiphu amahle kakhulu wokuzibona, nokuthi kungani lokhu kwenzeka. Abaningi kungenzeka ukuthi sebevele bafuna ukuba nenhlanhla futhi benze isifiso lapho besibona. Yize kungukungcola okuncane okukhona, kwabanye kungaba yinhlanhla ukubona okunye. Masingakhohlwa ini Esibhakabhakeni esicacile, ngaphandle kwamafu noma ukungcola okuncane, namhlanje kusihlwa kungatholwa ngamandla amakhulu.
Okokuqala nje. Zivelaphi izinkanyezi?
I-Comet Swift Tuttle. Avelaphi amaPerseid
Umzimba wasezulwini abavela kuwo yiComet Swift Tuttle. Kusuka ezinsaleleni zomsila we-comet. Igama layo lisuselwa kuDewis Swift noHorace Parnell Tuttle, ababengabatholi ngoJulayi 19, 1862. Ngobubanzi obungamakhilomitha angama-26 nomjikelezo ozungeze iLanga leminyaka eyi-135. Isikhathi sokugcina lapho 'savunyelwa' ukubonakala kwakungo-1992, okwaholela ku-THZ, noma izinga lomsebenzi wehora ngalinye, lama-300.
Kusukela lapho, umsebenzi ubuye wehla futhi wazimisa ngokujwayelekile, i-THZ ye-100. Kumele kuqashelwe ukuthi ngonyaka we-2009 kwakukhona ukudlula emfucumfucwini wemfucumfucu enabantu abaningi, eyanikeza i-THZ engu-173. Ama-meteor anejubane elikhulu, njengoba ehamba ku-59km / s. Isikhathi salo somsebenzi side kakhulu, ngakho-ke, yize isiqongo sikulesi sikhathi, Kungenzeka ukubona ezinye phakathi kukaJulayi 16 no-Agasti 24.
Igama elisemthethweni yiPerseids, ngoba ziphuma enkanyezini kaPerseus. Kepha baziwa kakhulu ngokuthi "izinyembezi zeSan Lorenzo". Lokho kungenxa yokuthi Agasti 10 usuku lwalo ngcwele. Enkathini Ephakathi Nesikhathi Sokuvuselelwa kabusha babehlala bevela nge-apogee ephezulu ngosuku uSan Lorenzo akhunjulwa ngalo, futhi kusukela lapho bayaziwa kakhulu ngaleli gama. Noma kunjalo, lo mkhuba wabhalwa okokuqala ku-AD 36
Ungababheka kanjani kahle?
Abantu abanezimoto bangakwazi hambisa ezindaweni ezingenakho ukungcola okukhulu kokukhanya. Futhi khumbula ukuthi, ukuqwala izintaba, ngasikhathi sinye, kwenza isibhakabhaka sicace bha. Futhi kungcono ukuvimbela isimo sezulu, hleze siye endaweni nje lapho kulindeleke khona amafu.
Kubantu abangenazo izimoto nasedolobheni, izincomo ziyafana noma zincane kodwa ziyasebenza edolobheni. Ezindaweni eziphakeme, futhi ngaphezu kwakho konke ukugwema ukuvezwa kakhulu ekukhanyeni noma ukuzungezwe yizakhiwo ezisivimbela ukuthi sibuke isibhakabhaka ngokugcwele. Noma kunjalo, ziyabonakala, kepha eziningi zazo zingabonakala.
Ukubheka kuphi?
Umbuzo ovela kaningi ekutheni sibheka kangakanani isibhakabhaka lapho sifuna ukubuka ngokukhanyayo "ukukhanya" kweshawa sezinkanyezi. Yebo yebo, kepha ngibheka kuphi ... Noma kuphi? Lapha lapho? Kuphi?
Ukubuka kufanele kubhekiswe ngakumlaza wePerseus, ngoba kubonakala sengathi kulapho abavela khona. Okusho ukuthi, uma sibheka ngamadigri angama-25 eNyakatho, noma eningizimu-ntshonalanga yePerseus, kuzoba lula kakhulu ukubona ngeso lengqondo ama-meteor asheshayo.
Yize "kulula" ukuzithola ngamehlo, kodwa singahlala sizwa ubusuku ngamandla. Sebenzisa izibonakude, noma sebenzisa ikhampasi kanye nemephu yasezulwini ukuze wazi ukuthi siqondisa amehlo ethu kahle. Lapho iphuzu selitholakele, akumangazi ukuthi okwesikhashana ukuthola eyodwa, kuvame ukwenzeka. Ngakho-ke into enhle kakhulu ukuphumula esihlalweni noma endaweni yokulala, ijazi elincane, nokuthile okudliwayo nokuphuzwayo ukuchitha isikhathi ngendlela emnandi.
Yeka ubusuku bemilingo eninabo nonke!
