Yini edingekayo ngokuyinhloko ukuze inkanyezi ibe a iplanethi okuhlalwa kuyo, ukuthi yizwe elinamanzi. Ngenxa yalesi sizathu kuthiwa isathelayithi yemvelo ye-Jupiter, e-Europa, ingahlala abantu njengoba kwatholakala ulwandle kuyo. Kuyathakazelisa ukucabanga ngamathuba okwenza umuntu abe sesimweni esifana nesethu. Njengoba kuphenywa, namanje akukatholakali ngesiqiniseko.

Nokho, isayensi ayikayeki ukufunda futhi ayikakhathali yikho. Ngakho-ke, phakathi kwemibuzo nophenyo bebelokhu befinyelela ezindaweni ezikude kakhulu. Mhlawumbe ku-Universe ephelele, yibo kuphela abagunyazwe ukuba babe nokuphila, singalabo abahlala ku- Iphasi Plan. Mhlawumbe amanye amaplanethi anomunye umsebenzi obalulekile endaweni yonke. Kuyoba yini? Asazi, kodwa basazama ukuthola okwengeziwe.
Phakathi kwalokhu ofuna ukukuqagela isayensi Imayelana nokwenzeka kokuphila kwamanye amaplanethi. Enye inketho iwukuhlonza izingxenye zamanye amaplanethi ezingenza kube lula ukuhlala kuwo. Kulokhu, kuyodingeka ukuthi kudluliselwe ukuphila okusemhlabeni kumaplanethi abhaliswe njenganokuhlalwa kuwo. Ngokusobala impilo yomuntu ibingeke ibekwe engcupheni ngokushesha, kodwa ibingacwaningwa ngokuningiliziwe.
Konke lokhu, okukhulunywe ngenhla, yilokho isayensi esekuphenye amashumi eminyaka namashumi eminyaka. Kangangoba izofika ithole ukuthi yini engaba iPlanethi Ephilayo EseMkhathini eyaziwayo kuze kube manje. Ngokwalesi sizathu, Uhambo oluya eCosmos kwenza kwenzeke lokho osekuphenywe kuze kube manje yi-NASA kanye nezazi zezinkanyezi ezimatasa ezifundweni eziqhubekayo eziphathelene nokuhlala kanye nokwenzeka kokuphila kwangaphandle komhlaba.
Ukuhlala kwe-exoplanet
Ku Uhlelo lomkhathi akubonakali ukuthi kungenzeka ukuphila nanoma iyiphi iplanethi okuhlalwa kuyo. Isikhathi esithile kwakusolwa iplanethi iMars. Abaningi bagomela ngokuzethemba ukuthi abafokazi futhi ikakhulukazi amaMartians akhona (njengoba kwakucatshangwa ukuthi uma kukhona ukuphila, ngokuqinisekile kwakuzovela kuMars). Nokho, ubuchwepheshe besayensi buye bafinyelela ukusondelana okukhulu neplanethi ebomvu, ngaphandle kokuthola imiphumela evumelana nalokhu kungabaza kwesayensi.
Ngisho noma kukhulunywa ngeplanethi engumakhelwane, i-NASA ayiboni impilo yamanje Mars. Ngakolunye uhlangothi, ihlola ukuthi kungenzeka yini ukuphila ezikhathini ezidlule. Kodwa namuhla awukwazi ukuhlala kuleyo ndawo, lapho kwakunamanzi kodwa manje asehwamukile nemithombo ayinalutho. Amanye amaplanethi eSolar System awanawo amanzi, kodwa eYurophu kuphela.
Europa Kuyisathelayithi yemvelo yeplanethi iJupiter, okungenzeka ukuthi inolwandle, ngaphansi kongqimba olukhulu lweqhwa. Kunenkolelo yokuthi uhlobo oluthile lokuphila lungaba khona kulolo lwandle. Kodwa-ke, lolu daba lusadingidwa futhi ososayensi basaqhubeka nokuphenya amanye amathuba. Enye yazo ukushiya iSolar System. Okusho ukuthi, emizimbeni yasezulwini ngaphandle kwalesi simiso, njengasesimweni sama-exoplanets noma amaplanethi angaphandle kwelanga.
Un i-exoplanet Kungaba ikhandidethi elingcono kakhulu kuze kube manje ukucinga ukuphila kwangaphandle noma indawo okuhlalwa kuyo enezimo ezifana neplanethi yethu. Le Planet Habitable cishe ingaba nezilwandle zamanzi awuketshezi, lezi kungaba inqwaba yamanzi amboze ngokuphelele indawo engaphezulu noma akwenza ngephesenti elingafika ku-90%. Bekungaba kuhle, nakuba bekungashiya indawo encane izakhamuzi ebezingase zime kuyo.
Izimo zeplanethi okuhlala kuzo
Uma sikhuluma iqiniso, ku-Viaje Al Cosmos sifuna ukucacisa ukuthi iqiniso liwukuthi amanzi amaningi akudingekile emhlabeni ukuze ukuphila kube khona kuwo. Kuncane kakhulu okuthatha amanzi amaningi ukumboza iplanethi yonke. Eqinisweni, emhlabeni wethu kukhona a 70% amanzi.
Lokhu kwenza Umhlaba ube yicala eliyingqayizivele. Lokhu siyakubona ngoba imbozwe ngamanzi angama-70%, futhi inomhlaba owanele ovumela ukuthuthukiswa kwempucuko. Ngakho, ukuba khona kwamanzi eMhlabeni kubalulekile ezinhlobonhlobo zezinto eziphilayo.
Leli cala elihlukile lichazwa ngoba umsebenzi wokwakheka komhlaba iqophe imigodi emikhulu lapho amanzi ahlala khona. Kodwa uma kwenzeka kwenye iplanethi enamatshe, kodwa enkulu futhi enesilinganiso samanzi afanayo noMhlaba, lokho kungasibekela ngokuphelele ingaphezulu. Lokhu kubangelwa wona kanye amandla adonsela phansi eplanethi enjalo, obekungavimbela ukwakheka kwenhlabathi enkulu ngokwanele ukuba isakaze amanzi futhi ishiye umhlabathi owomile.
Nokho, abacwaningi baye bathola kalula amanzi kumaplanethi angaphandle esimiso sethu sonozungezilanga. Inkinga ngalokhu ukuthi amanzi abawatholayo angaphezu kwendawo yokuhlala. Okusho ukuthi amanzi ayiqhwa, njengasendabeni yesathelayithi yase-Europa osekukhulunywe ngayo. Emaplanethini angaphakathi, kuye kwaba nzima kakhulu ukubona ukuthi akhona yini amanzi. Kwethenjwa ukuthi ngesibonakude sasemkhathini UJames Webb Kuzokwazi ukusungula izilinganiso zomkhathi weplanethi futhi ngaleyo ndlela wazi ukuthi inamanzi noma cha.
Ososayensi baphinde babonise ukuthi izindawo okuhlalwa kuzo zichazwa njengebanga elanele phakathi kweplanethi nenkanyezi yayo ukuze kugcinwe izinga lokushisa elisesilinganisweni elingagcina amanzi awuketshezi. Ulwazi esinalo kuze kube manje olokuhlanganiswa kwe i-kepler space telescope, obekuyisihluthulelo sokuthola imihlaba emisha.
amaplanethi endaweni okuhlalwa kuyo
Isibonakude i-Kepler siphinde sathola abantu abangaba ngu-50 beplanethi etholakala endaweni indawo okuhlalwa kuyo. Ukuba nento evumayo, usayizi oseduze noMhlaba. Ngokukhethekile ezingaphezu kuka-30 zazo eseziqinisekisiwe kakade. Lokhu okutholiwe kuze kube manje yikhona kuphela okuqukethe inani labantu lala maplanethi analogu aseduze nomhlaba, acishe alingane nosayizi nokuzungeza kwawo njengoMhlaba, njengoba kuboniswa ama-rovers.

Kuze kube manje ukuvama kwayo emthaleni kungaqondwa. Yilokhu okuzosiza ukwazisa ukuklama kwe ohambweni oluzayo I-NASA ukuya ngqo emfanekisweni womunye uMhlaba. Idatha engasiza i-NASA idizayine isibonakude sasemkhathini ngeminyaka yawo-2030. Isibonakude singaba sikhulu futhi sibe namandla anele ukuhlukanisa izithombe zamaplanethi azungeze ezinye izinkanyezi.
I-Gliese 832c: Iplanethi okuhlalwa kuyo
Ngemva kocwaningo olungaka, ulwazi lwakamuva mayelana nokuhlala kwamaplanethi ukuthi iplanethi ekwazi ukuhlala kuyo ingaba khona nje iminyaka engu-16 yokukhanya ukusuka eMhlabeni. Lo mzimba kuthiwa a super emhlabeni guy. Yiplanethi esesimisweni esifana kakhulu nesethu.
Ngaphezu kwalokho, futhi iqukethe iplanethi efana ne-Jupiter, okubonisa ukuthi uhlelo lungase luzinze futhi kungenzeka luphathe amanye amaplanethi anezimo ezifanele zokuphila.
Nokho, iplanethi okuhlalwa kuyo ifana kakhulu noMhlaba. Ngakolunye uhlangothi, ingaba khona ohlelweni lwezinkanyezi oluqhele ngebanga leminyaka engu-16 yokukhanya. Le planethi ye-extrasolar bheka 832c, efihlwe ohlelweni lwezinkanyezi olubizwa nge-Gliese 832. Okubalulekile, i-Gliese 832 iyinhlaza ebomvu futhi ingaphansi nje kwengxenye yesisindo neradius yeLanga lethu.
I-exoplanet etholakele iwuhlobo olubizwa ngokuthi i-super-Earth, ezungeza eduze kwenkanyezi i-dwarf ebomvu i-Gliese 832 nokuthi itholakala kumlaza weGrus ebangeni elingaba iminyaka engu-16 ukukhanya ukusuka eplanethini yethu enguMhlaba. Lokhu kungamakhilomitha alinganiselwa ku-151 billion.

Ukuba neplanethi enkulu ezingxenyeni ezingaphandle (iplanethi efana ne-Jupiter) kanye neplanethi okungenzeka inamatshe engxenyeni engaphakathi (njengoMhlaba), uhlelo lweplanethi ye-Gliese 832 lungacatshangwa njengenguqulo efanayo yeSistimu sethu Solar, Ngokuvumelana nalokho kuboniswe ngumbhali-ndawonye wocwaningo lwe Inyuvesi yaseNew Wales. I-Gliese 832c ingase ibe i-Habitable Planet yalolo hlelo lwenkanyezi.
