I-Perseid, eyaziwa nangokuthi "Izinyembezi zika-Saint Lawrence," iwumbukwane wasezulwini othakazelisayo owenziwa minyaka yonke ngo-August. Lena ishawa ye-meteor ekhanyisa isibhakabhaka ebusuku ngemibane ekhazimulayo, edlulayo. Izinkulungwane zabantu zizobuka lolu hlelo ngalobu busuku buka-August. Kuningi ilukuluku lamaPerseids ukuthi ubungazi.
Kulesi sihloko sizokutshela mayelana ne-curiosities eyinhloko yama-Perseids ukuze ube nombono uma kuziwa ekuhambeni ukuwabona.
Yini
Lawa ma-meteor empeleni ayizinhlayiya ezincane zothuli namatshe ezashiywa yi-Comet Swift-Tuttle emzileni wayo ozungeza iLanga. Uma uMhlaba udlula kulelifu lezinhlayiyana, ezinye zazo zingena emkhathini wethu ngesivinini esikhulu futhi zishise ngenxa yokungqubuzana komoya. Yile nqubo evuthayo edala imizila yokukhanya emangalisayo esibhakabhakeni, esivame ukuyibiza ngokuthi "izinkanyezi ezidubulayo."
Inani eliphakeme lomsebenzi we-Perseids livame ukwenzeka maphakathi no-Agasti, ngokuvamile cishe zi-11 kuya ku-13 kuleyo nyanga. Ngaleso sikhathi, inani lama-meteor abonakalayo ngehora lingashaqisa, lifinyelele emashumini noma ngisho nangaphezulu ezindaweni ezinesibhakabhaka esimnyama, esicacile. Kodwa-ke, ama-Perseid abonakala amasonto ambalwa ngaphambi nangemva kokuphakama kwawo, ngakho-ke unethuba elihle lokuwabona ngisho noma ungakwazi ukuwabona endaweni ephakeme kakhulu.
Ukuze ujabulele lo mbukiso wasezulwini, kungcono ukubalekela izibani zedolobha futhi uthole indawo enesibhakabhaka esimnyama nesicacile. Akukho mishini ekhethekile edingekayo; vele ulale ubheke phezulu esibhakabhakeni. Nakuba ama-Perseids eyisenzakalo esidume kakhulu sohlobo lwayo, izihlambi ezimbalwa ze-meteor zenzeka ngempela unyaka wonke, ngasinye sihlotshaniswa nenkanyezi enomsila ehlukile.
Izithakazelo zamaPerseids
Kungani zibizwa ngokuthi "izinyembezi zikaSanta Lawrence"?
E-Spain, le meteor shower yaziwa nangokuthi Izinyembezi zaseSan Lorenzo. Incazelo ilula: U-Agasti 10 yi-Fiesta de San Lorenzo, ehambisana nosuku olungcono kakhulu lokubuka lesi sigameko sasezulwini. Kodwa kungani ukhuluma ngezinyembezi zakhe?
USan Lorenzo washiswa ephila ngo-Agasti 10, 258 futhi, njengoba indaba iqhubeka, akazange amemeze noma azame ukubaleka. Izinyembezi zakhe zaziwukuphela kwezimpawu zobuhlungu, sasizibona kanjalo esibhakabhakeni ngalobo busuku basehlobo. Ezinye izindaba zithi i-meteor imele inhlansi yomlilo lapho abulawelwa khona ukholo.
Wayengubani uPerseus?
Abizwa ngokuthi amaPerseid ngoba kubonakala sengathi avela emlaza wePerseus. Kodwa uyazi ukuthi ngubani leli qhawe lezinganekwane zamaGreki?
UPerseus wayeyindodana kankulunkulu uZeus kanye noDanae ofayo. Phakathi kwezenzo zakhe eziningi, udume ngokubulala iMedusa, i-gorgon enamandla akhethekile: bonke abantu, izilwane noma izinto ambuke emehlweni aphenduke amatshe. Le nganekwane ivela izikhathi eziningi kwezobuciko. Isibonelo, ePrado sinemifanekiso yemabula emhlophe ethi "Medusa" yombhali ongaziwa. Siphinde sathola ukuthi le ndaba ingasetshenziswa njengokugqugquzela imidwebo eyahlukene.
Enye yezindaba zakhe ezikhumbuleka kakhulu yilena ayidlala no-Andromeda, oboshwe ngamaketango emadwaleni olwandle. U-Poseidon wathumela u-Ceto, isilwane sasemanzini, ukuba simbulale, kodwa uPerseus wakwazi ukumnqoba ngokumfaka ikhanda likaMedusa. Ngale ndlela, wasindisa owesifazane osemusha owayezoshada naye kamuva.
Ingakanani ishawa ye-meteor?
I-Perseid Meteor Shower ibukeka njengebhola lomlilo elikhulukazi elinqamula esibhakabhakeni, kodwa akunjalo. Izinhlayiya ezibangela imvula ye-meteor zilingana nohlamvu lwerayisi. Izigigaba esizibonayo kungenxa yejubane ezingena ngalo emkhathini woMhlaba ngesivinini esingaphezu kuka-200.000 XNUMX km/h.. Esibalweni esinzima, isivinini singamakhilomitha angama-60 ngomzuzwana. Njengoba bedlula emkhathini, bayabhidlika bese kuvela ukukhanya ebesikulindile ngabomvu.
Kuyingozi?
Ngobuchwepheshe, ama-meteor shower kufanele abizwe ngokuthi ama-meteor shower ngoba esikubonayo akuzona izinkanyezi zangempela. Ukuze uphendule lo mbuzo, kufanele kucatshangelwe ukuthi amanye ama-meteor ayakwazi ukudlula emkhathini futhi afinyelele ebusweni bomhlaba (abe ama-meteorite) ngaphandle kokubola okuphelele. Kodwa-ke, endabeni yamaPerseids, ama- meteor abangela ukuba ahlakazeke ngebanga elingamakhilomitha angaba ngu-100, futhi njengoba sishilo ngaphambili, awamakhulu kakhulu, ngakho-ke kunzima kuwo ukusinda ongqimbeni lwethu lokuzivikela.
Okunye okuthakazelisayo kwamaPerseid amancane
Nakuba izithakazelo zama-perseids abaluleke kakhulu sezivele zishiwo, sizobona ezinye zezinto ezingabalulekile kangako:
- Umsebenzi wenyanga yonke: Nakuba ukuphakama komsebenzi kuyisikhathi lapho kubhekwa khona ama-meteor amaningi ngehora, ama-Perseids angabonakala cishe inyanga, kusukela phakathi noJulayi kuya ekupheleni kuka-August. Njengoba sisondela esiqongweni, inani lama-meteor liyakhula kancane kancane.
- Imicimbi okufanele ibukwe njengeqembu: Ama-Perseid ayizaba ezinhle zokuhlangana nabangane, umndeni, noma ngisho nabantu ongabazi abanentshisekelo efanayo kwisayensi yezinkanyezi. Izindawo eziningi zokubuka izinto, amakilabhu ezinkanyezi, namapaki emvelo ahlela imicimbi ekhethekile ukuze abuke amaPerseid. Kuyithuba eliyingqayizivele lokujabulela umbukiso nokufunda okwengeziwe ngesibhakabhaka esigcwele izinkanyezi.
- Izinganekwane nezinsumansumane: Kuwo wonke umlando, izihlambi ze-meteor ezifana ne-Perseids ziye zaphefumulela ezihlukahlukene zezinganekwane kanye nezinganekwane emasikweni ahlukene. Kusukela ekuchazeni okuyinganekwane kuya kubabikezeli bezenzakalo, lezi zimangaliso zasemkhathini ziye zashiya uphawu lwazo emcabangweni womuntu.
- kungenzeka izimoto: Nakuba ama-Perseid meteor amaningi emancane futhi asha aphelele emkhathini, ngezinye izikhathi kungase kwenzeke i-bolide, okuyi-meteor egqamile futhi ebabazekayo. Lezi zenzakalo zijabulisa kakhulu ukufakaza futhi zingashiya umbono ohlala njalo.
Ngithemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana nezinye zezinto ezinhle kakhulu ze-Perseids.
