Iintsalela zekometethi eyindumasi edumileyo yesixokelelwano selanga ziya kukhanyisa isibhakabhaka ebusuku ngo-Okthobha xa iOrionid meteor shawa ibona uthuli kunye nenkunkuma ibetha umoya ojikeleze umhlaba. Kubonakala naphina kwiplanethi phakathi kobusuku kunye nokusa kufutshane nekroza leOrion the Hunter, ubusuku obunqabileyo balo nyaka buza kuphazanyiswa kukukhanya kwenyanga okuqinileyo, kungoko kujongwa kakhulu ngolwesiBini okanye ngeLwesibini, Okthobha 16.
Inini i-Orionid meteor shower ngo-2018?
Ngokwesiqhelo, kufanelekile ukulinda i-meteor shower to peak ngaphambi kokuba uphume, kodwa lo nyaka we-Orionid meteor shower uza kujongwa kakuhle kwangoko. Nangona ubusuku bokuphakama bungeCawa, nge-Okthobha ye-21 nakwiiyure zokuqala zikaMvulo, i-Orionid meteor shower yaqala ngo-Okthobha wesi-2 kwaye ayipheli de kube ngu-Novemba. 7. Ke kutheni ubuthintele ubusuku obunqabileyo ngo-Okt. 21? Kukufutshane kakhulu nenyanga epheleleyo ngo-Okthobha u-24, okuthetha ukuba kuya kubakho ukungcola kokukhanya okuninzi kwendalo.
Nangona kunjalo, oko akuthethi ukuba awukwazi ukubona i-Orionid meteor shower kulo nyaka.
Uyibona njani ishawa yeOrionid meteor
Akukho zixhobo zikhethekileyo ziyafuneka, lixesha elifanelekileyo. (Ngapha koko, iteleskopu iya kuwanciphisa kakhulu amathuba akho okubona iinkwenkwezi zokudubula.) Obu busuku buphezulu bunokonakaliswa yinyanga epheleleyo, kodwa ngokucwangcisa ngononophelo, kuyenzeka ukuba ubone i-Orionid meteor shaft kubuninzi bobuqaqawuli bayo. Ukuba uphumela ngaphandle nje ezinzulwini zobusuku ngo-Okthobha u-16, malunga nexesha elifanayo iipesenti ezingama-50 ezikhanyisiweyo zekota yokuqala yenyanga, kuya kufuneka ube nesibhakabhaka esimnyama ngokwaneleyo ukonwabela ngeenxa zonke nge-15-20 yeenkwenkwezi zokudubula ngeyure phakathi kobusuku kunye nokuphuma kwelanga.
Liliphi elona xesha lilungileyo lokubona iinkwenkwezi zokudubula?
Iveki eqala ngo-Okthobha u-15, i-2018, lixesha elihle lokujonga iinkwenkwezi ngamathuba okudubula kweenkwenkwezi. Ukuze wandise amathuba akho, hlala kude nongcoliseko olunamandla lokukhanya, ezinje ngezibane zasesitalatweni, kwaye ulinde imizuzu engama-20 de amehlo akho aqhelane nobumnyama.

Iinkwenkwezi zokudubula ngokwazo zibangelwa ngamasuntswana amancinci abethwa ngumoya woMhlaba. Njengoko oko kusenzeka, amasuntswana ayatshisa kwaye avutha okwesibini ukwahlula. IHalley's Comet izakubuyela kwinkqubo yelanga ngonyaka we-2061.
Kuphi kwaye nini ukujonga iinkwenkwezi zokudubula
Ukusukela ukuba i-Orion ye-Orion iyakulindeleka emazantsi malunga ne-2 kusasa phakathi ku-Okthobha u-2018, loo nto iphantse ibe nini kwaye phi ukujonga iinkwenkwezi zokudubula ukusukela elo lixesha uMhlaba udibana nomsinga wentlabathi. Nangona kunjalo, leyo ingcebiso ngokubanzi kuba iinkwenkwezi zokudubula zinokuvela naphi na esibhakabhakeni ebusuku. Ngapha koko, ukuba uyababona kufutshane neOrion, kunokwenzeka ukuba batyhafe. Ke ukubukela ngaphambi kobusuku kulungile.
Zivela phi iiOrionids?

Kwimeko yokuhlanjwa kwe-meteor ye-Orionid, indawo ekhanyayo ngokucacileyo ikwi-constellation yeOrion, ethi inyuke empuma ngorhatya ngo-Okthobha. Nangona kunjalo, inqaku eliqaqambileyo alikho kufutshane neenkwenkwezi ezintathu ezenza i-Orion's Belt edumileyo, kodwa kufutshane nenkwenkwezi edumileyo iBetelgeuse ngasentla nje. Awungekhe uyiphose; lo mbala mkhulu weenkwenkwezi obomvu ungumnikelo.
