Phakathi kwezona ziganeko zinomtsalane nezimangalisayo zecosmic ezinokubonwa eMhlabeni, yishawari yemeteor. Isiganeko esimangalisa iliso lenyama, lizisa umboniso wokukhanya othakazelisayo. Ngaphandle kothandabuza, ngamava akhethekileyo ekufuneka kunikelwe ubungqina ngaxa lithile.
Kusenokubonakala ngathi ziziganeko ezenzeka zodwa kwaye ngokungalindelekanga. Ngokunjalo, kuqhelekile ukucinga ukuba, ukubona ishawa yemeteor, kufuneka ube nethamsanqa. Nangona kuyinyani ngokuyinxenye, kuyamangalisa ukwazi ukuba iishawari zeemeteor zixhaphake kakhulu kunokuba zibonakala. Ngaloo ndlela, kufuneka ulungele kwaye wazi ukuba baya kufika nini.
Unokuba nomdla kwinqaku lethu: Ngaba uyafuna ukwazi ukuba yayingubani umfazi wokuqala esithubeni?
Zonke iinkcukacha zeshawari yeenkwenkwezi, ezandleni zakho
Ngamafutshane, imvula yeenkwenkwezi okanye eyaziwa ngokuba yimeteor shower, ziziganeko zeenkwenkwezi ezinomdla ngokubanzi. Ngaphandle kokuba ithathwa njengento ehlala ifundwa, inodumo olukhulu phakathi kwabantu abaninzi. Ngenxa yoko, akufuneki ukuba ube yingcali ukuba ube ngumthandi wendawo kunye nayo yonke into equkayo.

Ukujikela kwimbono yezobugcisa, i-meteor shower yenziwa kwi-comets okanye i-meteors. Ukulandela indlela yokuqala okanye i-cometary, uchungechunge lwemiba ebalulekileyo kufuneka luqale luthathelwe ingqalelo.
IiComets, njengoko zijikeleza uMhlaba okanye ngaphakathi kweSolar System ngokubanzi, zisebenzisana nezinye izinto. Ezi zingumoya welanga kunye namandla ngokwawo akhutshwa yinkwenkwezi engumzali. Xa imozulu yasemajukujukwini ibetha umphezulu wecomet, ibangela ukukhululwa kwamasuntswana ecosmic kuyo.
La masuntswana, aqhele ukubizwa ngokuba yi "meteor swarms," kwakhona alandela i-orbit ye-comet enxulumene nomzimba wesibhakabhaka onjengoMhlaba. Ngexesha elithile, i-swarm ingena kwi-atmosphere, ivutha ngenxa yempembelelo yoqhagamshelwano kunye nokukhuhlana de ivelise imvula.
Kwimeko yesibini, kuxhomekeke kubungakanani, i-meteor okanye i-meteorite iyakwazi ukuvelisa imvula yeenkwenkwezi. Ekubeni zincinci njengevazi, iimitha zomoya ziyaqhekeka xa zidibana nomoya, ziqala ishawa ngolo hlobo. Nangona kunjalo, ubukhulu bayo abuyi kulinganisa kunye nemeko yangaphambili.
Ukuba zixhaphake kakhulu… Ke, iyakuba nini ishawa ye-meteor elandelayo ka-2020?
Njengoko kukhankanyiwe, ezi ziganeko zixhaphake kakhulu kunokuba zibonakala ngathi. Ke ngoko, ukuqonda ngakumbi malunga nabo, kufuneka uqale ujikeleze kwiindidi zeeshawari zemeteor.
Ngonyaka, ukuya kuthi ga kwi-7 iindidi zeziganeko ze-stellar zenzeka ukuba ukuthandana ngokupheleleyo noluntu. Nganye kuzo igubungela ixesha okanye ixesha elithile lonyaka, ukuze, nangawuphi na umzuzu, ibe nokubonwa. Kakade ke, ukuba nje amanyathelo afanelekileyo athatyathwa kule njongo.
IiQuadrantids ezintle
Kwisithuba esiphakathi kwe-1 kaJanuwari kunye ne-5th, imvula entle ye-Quadrantids iyenzeka. Oko kukuthi, yayiyi-2020 meteor shower eyavela kwinyanga yokuqala yonyaka.
Ngokukodwa, yimvula esebenzayo, eqaqambileyo kwaye engaguqukiyo ngelixa iqhubeka. Zibonakala ngokulula nakweyiphi na indawo, nje ukuba akukho ngcoliseko lokukhanya. Ngokwahlukileyo koko, zezona zilula kwaye kulula ukuzifumana.
Epreli kunye nokubuya kweeLyrids
Emva kokuba isiganeko seQuadrantid senzeka, kufuneka ulinde kude kube ngu-Epreli ukuze ubone ishawari yemeteor kwakhona. Ngokukodwa, phakathi kwe-16 kunye ne-26 ka-Epreli njengoko kunjalo, kulapho enye yezona mvula zinamandla. Baziwa ngokukodwa njenge "Lyrid Fireballs" ngenxa yokukhanya kwabo okukhulu.
Ukubonwa rhoqo kweePerseids
IiPerseids, Babizwa ngegama labo kwiqela leenkwenkwezi elidumileyo lasePerseus, yenye yezona mvula zide zemeteor ngo-2020. Ngapha koko, ixesha layo lexesha ligubungela iintsuku eziphakathi kwe-17 kaJulayi kunye ne-24 ka-Agasti. Ngokunjalo, zibonwa njengeenkwenkwezi ezidubulayo eziqhelekileyo, ngaphandle kokukhanya okuninzi, kodwa ngesantya esimangalisayo.
IiDraconids ezinamandla
Idityaniswe neqela leenkwenkwezi ze-Dragon, luhlobo lweshawari yemeteor eyenzeka ngo-Okthobha. Ke ngoko, igubungela iintsuku ukusuka nge-6 ukuya kwi-10 ka-Okthobha, kunye ne-boom ephezulu kubusuku obubini bokugqibela. Ngapha koko, intlantsi kunye nokukhanya kukhulu xa kuthelekiswa neePerseids, ngoko ke ziyabonakala nasekutshoneni kwelanga.
IiOrionids kunye nobukho bazo obude ebusuku
Ivela kwikroza le I-Orión, iiOrionids Kananjalo banenqanaba eliphezulu lomsebenzi. Ukuba yenye yezona zide kakhulu, iquka iintsuku ezisuka kwi-2 ngo-Oktobha ukuya kwi-20 kaNovemba ngokubanzi. Xa uthi krwaqu nje, yishawa ekhawulezayo, ayikhazimli kakhulu kodwa inomtsalane ngokufanayo.
I-Leonidas enemibala
Eyaziwa kakhulu ngokubonisa ukukhanya okubomvu okugqithisileyo kunye nomkhondo oluhlaza, kuvela iiLeonids. Zihamba ukusuka ngoNovemba 6 ukuya kwi-30 kaNovemba ngokukodwa, zihlobisa isibhakabhaka ngoluhlu lwazo lwemibala.
IiGeminids ezintsonkothileyo
Ukususela nge-7 kaDisemba ukuya kwi-17 kaDisemba, iiGeminids zenza ubukho bazo emhlabeni. Ngencopho yemvelaphi kufuphi neqela leenkwenkwezi zeGemini, yimvula ehlala ixesha elide, enamandla kwaye esebenzayo kakhulu. Nguye ojongene nokuhombisa umoya xa kufika uDisemba.
Kwenzeka njani ukujonga ishawa yemeteor namhlanje? Funda elona qhinga!

Inyathelo lokuqala lokujonga ishawari yemeteor namhlanje okanye namhlanje, kukwazi ngokuthe ngqo umhla osondelayo. Ngokufanayo, njengengcebiso, iimvula ze-meteor zibonakala ngakumbi ngexesha lasekuseni.
Isizathu silula, ngelo xesha, bafikelela kwindawo ephezulu yokungena eMhlabeni. Oko kukuthi, unxibelelwano lwabo oluphambili kunye ne-atmosfera luya kuba lukhulu kwaye luhlala ixesha elide, ngoko baya kubonakalisa ukukhanya okungaphezulu.
Emva koko, elinye inyathelo elibalulekileyo kukumka esixekweni, ukungena kwindawo apho ungcoliseko lokukhanya lungaphazamisi. Okulandelayo, ukwazi indawo yeminye yeenkwekhwezi, leyo ihambelanayo ikhona. Nangona kunjalo, ukujonga ishawa yemeteor namhlanje kunokwenzeka nangaphandle kokhokelo lwekroza, kuba zikhanya esibhakabhakeni.
