Siyazi ukuba indalo iphela yenziwe ngamawaka ezigidi zeenkwenkwezi ezidityaniswe ngamakroza. Enye yeenkwenkwezi ezaziwayo yi inkwenkwezi Vega. Yinkwenkwezi ebekwe kwikroza leLyre kwaye yinkwenkwezi yesihlanu eqaqambileyo kwisibhakabhaka sonke sasebusuku. Ukuba sikwinxalenye ye-hemisphere esemantla yesibhakabhaka, yeyesibini eqaqambileyo emva kuka-Arthur. Ime kuphela kumgama weminyaka engama-25 yokukhanya ukusuka kwiplanethi yethu kwaye yenye yeenkwenkwezi eziqaqambileyo kufutshane ne inkqubo yelanga.
Kule nqaku siza kukuxelela yonke into ofuna ukuyifumana malunga nenkwenkwezi yeVega kunye neempawu zayo.
Iimpawu eziphambili
UVega yinkwenkwezi ethathelwa ingqalelo njenge-zero ngombala kunye nobungakanani bokubonakalayo. Emva kokuthabatha amaxabiso kwiifilitha eziluhlaza kunye noluhlaza, isalathiso sombala we-BV ngu-zero. Ukusuka emhlabeni, u-zero ukwabubukhulu bayo obubonakalayo. Ngenxa yesantya sokujikeleza okuphezulu, ukongeza kumahluko obonakalayo kubushushu bomhlaba, ikwafumana ubunzima bokuthamba ngokungaqhelekanga, ukubhalisa iqondo lobushushu kumphezulu weikhweyitha nakwiipali. Enye yezibonda zeenkwenkwezi zikhomba eMhlabeni.
Olunye uphawu lwenkwenkwezi iVega yidiski enothuli ejikeleze inkwenkwezi. Iibhiliyoni zeminyaka eyadlulayo, ilanga ngelingqongwe ngale ndlela. Idiski yangoku yeVega inokuba yimvelaphi yeenkqubo zeplanethi ezizayo ezifanayo nezethu. Kungenzeka ukuba namhlanje uneplanethi enye yohlobo lweJovian okanye iNeptunian. Idiski yothuli ejikeleze iVega ibandakanya inkunkuma evela kungqubano oludlulileyo phakathi kweeasteroids. Banako ngokunjalo ibe zizinto ezincinci zeprotoplanetary ezizahlulahlula kwaye zenze izakhiwo ezifanayo nebhanti yethu yeKuiper.
I-Vega yinkwenkwezi eqaqambileyo kwikroza leLyra kwihlobo elisentla. Ngobusuku behlobo eMantla eIkhweyitha, inokubonakala kufutshane ne-zenith kumbindi womntla. Ukusuka kububanzi ukuya emazantsi, kunokubonwa kumantla enyakatho ebusika kwi-hemisphere esemazantsi. Ububanzi bungu-38,78 °. Inkwenkwezi yeVega inokubonwa kuphela kububanzi basentla kuma-51 ° S, ke iVega ayinakubonwa eAntarctica okanye kwelona zantsi lisemazantsi eMzantsi Merika. Kububanzi obungu-51 ° N, iVega iyaqhubeka ngaphezulu kwesibhakabhaka njengenkwenkwezi ejikelezayo.
Iintsomi ngeenkwenkwezi zeVega
Kwintsomi yamandulo yamaGrike, le nkwenkwezi yohadi lokulondolozwa kweembali okuyilwe nguHermes kwaye yanikwa uApollo ukumhlawulela ngobusela. U-Apollo wayinika u-Orpheus kwaye, Ekufeni kwakhe, uZeus waguqula ihadi yaba liqela. UVega umele isiphatho sohadi.
Kwintsomi yamaTshayina, kukho ibali lothando malunga noQi Xi, apho uNuu Lang (Altair) noonyana bakhe ababini (β no γ Aquila) bohlulwe kunina, uZhinu (Vega), ohlala ngasemlanjeni kwelinye icala . , indlela yobisi. Nangona kunjalo, unyaka nonyaka ngomhla weshumi elinesixhenxe wekhalenda yenyanga yaseTshayina, kuyakubakho ibhulorho, ke ngoko uNuu Lang noZhi Nu banokubuyela kunye ngexesha elinye.
Igama u-Wega (kamva uVega) livela kuguqulelo lwegama lesi-Arabhu elithi ,qi, elithetha "ukuwa" okanye "ukuhla."
Inkwenkwezi yeVega kunye nabangaphandle
Nangona oku kungatshintsha kungekudala. Iqela labaphandi lithembele kwiminyaka yokujonga imeko yenkwenkwezi. Ukuba ezi zinto zifunyanisiweyo zichanekile, ii-exoplanets ezinokubakho kwiVega kwindlela yayo ziya kuba zigqithile. Isondele kakhulu kwinkwenkwezi kangangokuba ithatha ngaphantsi kweentsuku ezimbini ezinesiqingatha zomhlaba ukugqiba isangqa esipheleleyo. Umzekelo, iMercury, iplanethi ekufutshane nelanga, Kuthatha iintsuku ezingama-88 ukugqiba umjikelo omnye. Ubushushu bakho buya kuba yinto egqithisileyo.
Ubushushu bomgangatho wayo ophakathi umalunga nama-2976 degrees. Le iya kuba yeyona exoplanet yesibini ishushu eyakha yabonwa. Uphando lunokunceda ekuqinisekiseni ukuba ngaba iVega yenkwenkwezi inokuba nezinye ii-exoplanets ezikufutshane. Emva kwayo yonke loo nto, njengoko abaphandi besitsho, sijongana nenkqubo enkulu kakhulu kunenkqubo yelanga. Ke ngoko, abanakugweba ukuba kukho ezinye iiplanethi ezijikeleze inkwenkwezi. Kule meko, owona mbuzo kukuba banako na ukuwafumanisa.
Exoplanets
Okwangoku, ngaphezulu kwe-4000 exoplanets sele ifunyenwe. Nangona kunjalo, kuwo onke amazwe angaphandle kwenkqubo yelanga, bambalwa kuphela abanomtsalane ngokwenyani. Zimbalwa kuphela ezifumaneka kwiinkwenkwezi eziqaqambileyo okanye ezikufutshane noMhlaba njengeVega. Ke ngoko, ukuba kukho iplanethi ejikeleze inkwenkwezi, inokufundwa ngokubanzi. Ukufunyanwa kwe-exoplanet ejikeleze iVega kuya kuba ziindaba ezilungileyo kakhulu, nokuba lihlabathi elingenakuhlala kude.
Abaphandi bafumene imiqondiso enokubonisa ubukho be-exoplanets. Inkwenkwezi iVega inokuba neJupiter eshushu. Ngamanye amagama, iplanethi enkulu, efana neJupiter, ijikeleza kufutshane kakhulu nenkwenkwezi yayo. Nangona kunjalo, ukusondela kwinkwenkwezi kunokuba iJupiter iselangeni, iya kuba yiplanethi eshushu kakhulu. Isenokuba yiNeptune eshushu. Le ndlela iyafana, kodwa ukusebenzisa iplanethi enobunzima obufanayo neNeptune, Jupiter. Ubuncinci, ngokutsho kwabaphandi, ukuba le exoplanet ikhona, iya kuba nobunzima obufanayo neNeptune.
Kwiingcamango kukho enye into egqithisileyo ekuthiwa yiplanethi enamatye. Oko kukuthi, siyazi ukuba iplanethi iJupiter inegesi. Kuyo nayiphi na imeko, nangona iplanethi yenkwenkwezi yakhe yayilikhosi, ikude ngaphandle kwendawo ekuhlalwa kuyo, ngenxa yoko asijonganga ne-exoplanet enomdla yokukhangela ubomi basemhlabeni. Ukusondela kakhulu kwinkwenkwezi iVega, Le exoplanet ifunda ngendlela yokuyinyusa ngokungathi ibhaluni. Inokuba njalo ke iqondo lobushushu kangangokuba nesinyithi sinokunyibilika emoyeni.
Ndiyathemba ukuba ngolu lwazi ungafunda ngakumbi malunga neenkwenkwezi iVega, iimpawu zayo kunye nokuyingqongileyo.
