Obu busuku buhle ukubabona buya kuba ngomso, ubusuku bomhla we-12 ukuya kowe-13. Yazi, incopho ngomso! Yimbonakalo ebonakalayo ukubona indlela abahlakazeka ngayo emoyeni, umgama oyi-100km kude.
Siza kukuxelela ezona ngcebiso zibalaseleyo zokuba uzibone, kwanokuba kutheni le nto isenzeka. Uninzi lunokuba sele lufuna ukuba nethamsanqa kwaye lenze umnqweno xa luyibona. Nangona kungcolisekile ukukhanya okukhoyo, kwabanye kunokuba nethamsanqa ukubona ezinye. Masingakulibali Esibhakabhakeni esicacileyo, ngaphandle kwamafu okanye ungcoliseko lokukhanya, ngokuhlwanje unokubonwa ngamandla.
Okokuqala. Zivela phi iinkwenkwezi?
I-Comet Swift Tuttle. Zivela phi iiPerseids
Umzimba wasezulwini abavela kuwo yiComet Swift Tuttle. Ukusuka kwintsalela yomsila we-comet. Igama layo livela kuDewis Swift noHorace Parnell Tuttle, ababengabafumanisi ngoJulayi 19, 1862. Ngobubanzi beekhilomitha ezingama-26 kunye nomjikelezo ojikeleze iLanga leminyaka eli-135. Ixesha lokugqibela "lokuvunyelwa" ukuba libonwe ngo-1992, okukhokelela kwi-THZ, okanye inqanaba lomsebenzi weyure, wama-300.
Ukusukela ngoko, umsebenzi uye wehla kwaye uzinzile ngokwesiqhelo, i-THZ ye-100. Kufuneka kuqatshelwe ukuba ngo-2009 bekukho indlela eya emfuleni wenkunkuma enabantu abaninzi, eyanika i-THZ ye-173. Iimeteor zinesantya esiphezulu, njengoko zihamba nge-59km / s. Ixesha lalo lomsebenzi lide kakhulu, ke ngoko, nangona incopho ikweli xesha, kunokwenzeka ukuba ubone ezinye phakathi kukaJulayi 16 no-Agasti 24.
Igama elisemthethweni yiPerseids, kuba ziphuma kwikroza lePerseus. Kodwa Baziwa njenge "iinyembezi zikaSan Lorenzo". Kungenxa yokuba Nge-10 ka-Agasti ngumhla wale ngcwele. KwiXesha lamaXesha Aphakathi kunye noRenaissance babehlala besenzeka nge-apogee ephezulu kumhla wokukhunjulwa kweSan Lorenzo, kwaye ukusukela ngoko bayaziwa ngeli gama. Nangona kunjalo, le nto yaqala ukubhalwa ngo-AD 36
Ungazijonga njani kakuhle?
Abantu abanezithuthi banako hamba uye kwiindawo ezingenalungcoliseko lukhanyayo. Kwaye ugcine ukhumbula ukuba, ukunyuka kweentaba, kwangaxeshanye, kwenza isibhakabhaka sicace ngakumbi. Kwaye kungcono ukuyikhusela imozulu, hleze siye nje kwindawo apho kulindeleke amafu.
Kubantu abangenazithuthi kwaye esixekweni, izindululo ziyafana okanye ziyafana kodwa zisebenza esixekweni. Kwiindawo eziphakamileyo, kwaye ngaphezulu kwako konke ukuphepha ukubhencwa kukukhanya okanye ujikelezwe zizakhiwo ezisithintela ukuba singaboni ngokupheleleyo isibhakabhaka. Nangona kunjalo, banokubonakala, kodwa uninzi lwabo alunakuqatshelwa.
Ungajonga phi?
Umbuzo ophindaphindwayo malunga nokuba sijonga esibhakabhakeni kangakanani na sikhangela ngokubonakalayo ukuthwebula "ukukhanya" kwemeteor shower. Ewe ewe, kodwa ndijonga phi ... naphi na? Apha phaya? Phi?
Ukujonga kufuneka kubhekiswe kwiqela lePerseus, kuba kubonakala ngathi kulapho bavela khona. Oko kukuthi, ukuba siyajonga Iidigri ezingama-25 emaNtla, okanye uMazantsi mpuma ePerseusKuya kuba lula kakhulu ukubona iimeteor ezikhawulezayo.
Nangona "kulula" ukubafumana ngamehlo, sinokuhlala sinamava ngobusuku obunamandla. Sebenzisa i-binoculars, okanye usebenzise ikhampasi kunye nemephu yasezulwini ukuze wazi ukuba siqondisa amehlo ethu kakuhle. Nje ukuba inqaku lifumaneke, ayothusi into yokuba sikhe sayifumana ixesha elithile, ihlala isenzeka. Ke eyona nto intle kukuba uphumle esitulweni okanye kwindawo yokulala, ibhatyi encinci, kunye nento yokutya nokusela ukuchitha ixesha ngendlela emnandi.
Yibani nobusuku bomlingo nonke!
