Bathola iplanethi entsha enezinga lokushisa elifana neloMhlaba

iplanethi efana neyethu

Ososayensi bathole iplanethi entsha elungele ukuhlala abantu, enamazinga okushisa afana neCaribbean. Isambulo sifana nohambo olungajwayelekile njengoba luphakathi kwezindawo eziseduze ongahlala kuzo.

Kulesi sihloko sizokutshela konke odinga ukukwazi mayelana ukutholakala kweplanethi entsha enezinga lokushisa elifana neloMhlaba.

Ukutholwa kweplanethi entsha enezinga lokushisa elifana neloMhlaba

Bathola iplanethi entsha enezinga lokushisa elifana neloMhlaba

Sikhona emkhathini omkhulukazi, egcwele izimfihlakalo ezingenakubalwa kanye nezindawo ezingahloliwe ezingaphezu kwamandla ethu. Esikhathini sethu samanje, sithembele kumathuluzi alinganiselwe esinawo ukuze sibheke futhi sakhe imibono eqanjiwe, ngaleyo ndlela sidale imibono yesayensi.

Kunesambulo sakamuva noma inkolelo-mbono eqinisekisa ukukhonjwa kwe iplanethi okuhlalwa kuyo. Lokhu kugomela kusekelwe ekubeni iplanethi iseduze nenkanyezi efana nelanga lethu kanye nomkhathi. Lezi zici azigcini nje ngokufaka isandla esimweni sezulu esilinganiselwe, kodwa futhi zithonya izimfanelo eziyingqayizivele zalo mzimba wasezulwini.

Kusukela ekuvikeleni ubuso beplanethi nezakhamuzi zayo emisebeni eyingozi nasezinsongweni zangaphandle kuya ekukhuthazeni indawo okungahlalwa kuyo, umkhathi udlala indima ebalulekile. Nakuba idatha eyengeziwe iyadingeka, kufanele kuqashelwe ukuthi ngisho nokusukela eminyakeni engu-40 yokukhanya, la maplanethi abonisa isithembiso esikhulu.

Sesha imingcele emisha

umhlaba neplanethi

Lapho befuna imingcele emisha futhi babaleke eMhlabeni ofayo, abantu bafuna amathuba okwanda. Kubalulekile ukukhumbula ukuthi singangena endaweni esingaziwa singakwazi ukubuya nganoma yisiphi isikhathi. Ngakho-ke, Ukuhlola umkhathi kuhlose ukuqinisekisa ukuphepha kosomkhathi, nakuba okwamanje inyanga isewukuphela kokunqoba.

Ngamakhono amanje ezobuchwepheshe, ukuqinisekisa ukubuya okuphephile kwabantu besuka kwenye iplanethi kuhlala kuwumsebenzi ongafinyeleleki. Nokho, kubalulekile ukuzilungiselela futhi ube nesiqondiso esicacile engqondweni uma umuntu efisa ukuthatha lolu hambo noma okungenani athathe izinyathelo zokuqala eziya kulo.

Ngokocwaningo lwakamuva olwenziwe ochwepheshe be-astrophysics e-Australia, I-Gliese 12 b ikhonjwe njengekhandidethi elihle kakhulu lokuphenya ikhono lamaplanethi alingana noMhlaba ezizungeza izinkanyezi ezibandayo ukuze zigcine umkhathi wazo. Lolu cwaningo luyisinyathelo esibalulekile sokuthuthukisa ulwazi lwethu mayelana nokuhlala kwamaplanethi ngaphakathi komthala wethu.

Kukhona ukungagwemeki okuthile kulolu hlelo, olwakhelwe ezisekelweni ezingalindelekile. Manje yisikhathi sokushintsha umbono wethu futhi sibone ngeso lengqondo indawo yonke njengeseyili enkulu, silindele indawo yamaplanethi okuhlalwa kuwo isintu.

Izici zale planethi

iplanethi efana nomhlaba

Ukucatshangelwa kwezinga lokushisa kubalulekile, hhayi kuphela ekuzivumelaniseni komuntu kodwa nasekutholeni izinsiza ezibalulekile. Ukutholakala kokudla emhlabeni wethu kuyisici esibalulekile esingenakushalazelwa.

Naphezu kokusondelana okuhlobene kwala maplanethi, Njengoba iqhele ngeminyaka engu-40 kuphela yokukhanya, ukuyifinyelela kuyodinga amashumi eminyaka ohambo noma ngisho namakhulu eminyaka ukuze kwenziwe ucwaningo oluqondile ngeplanethi.. Nokho, lokhu akusho ukuthi indawo yethu esiyifunayo ayinakufinyelelwa.

I-cosmos enwebekayo iyembuleka, ilungele ukuletha izambulo ezibalulekile futhi inikeza isiqondiso esengeziwe ekuphishekeleni kwethu ukuphila ngokungapheli. Namuhla, ososayensi bajabulile ngokuvela kwendawo yasezulwini enesithembiso njengendawo yokuhlala yesintu engaba khona.

Ukuba khona komkhathi osekela ukuphila noma amanzi akunakubonwa ngelensi yesibonakude. Ngakho-ke, kufanele sinwebe ukubonwa kwethu ukuze kuhlanganise nentuthuko ebalulekile ehlobene ngokungenakuphikwa.

Ukuhlolwa kokuqala, okwamanje okwenziwa ngosizo lwemininingwane eminingana ebalulekile, kubaluleke kakhulu. Kubalulekile ukuthi senze amalungiselelo okulindela inani elandayo lamaplanethi anokufana okuphawulekayo nowethu. Inqobo nje uma isibonakude sihlonza ukuba seduze kwenkanyezi futhi sihlangabezana nemibandela ethile yosayizi nokuqondanisa, amandla okuhlala ayasebenza.

Izimpawu zokuthi iplanethi ihlaleke

Ukuze iplanethi ithathwe njengokuhlala kuyo, kufanele ihlangabezane nochungechunge lwezici ezibalulekile ezivumela ukuthuthuka nokondleka kokuphila njengoba sikwazi:

  • Ukuba khona kwamanzi awuketshezi: Amanzi awuketshezi abalulekile kuzo zonke izinhlobo zokuphila ezaziwayo. Ukuba khona kwezilwandle, imifula noma amachibi kusiza ukuba khona kwezinqubo ezibalulekile ze-biochemical.
  • Izinga lokushisa elifanele: Izinga lokushisa elingaphezulu kweplanethi kufanele lihambisane nokuphila. Lokhu ngokuvamile kusho uhla lwamazinga okushisa lapho izinto eziphilayo zingaphila futhi zenze imisebenzi yazo ye-metabolic.
  • Isimo sezulu esimeme: Umkhathi owanele ubalulekile ukuze uvikele ukuphila emisebeni eyingozi futhi ugcine izinga lokushisa lizinzile. Umkhathi kumele uqukathe amagesi adingekayo empilweni, njengomoya-mpilo wezinto eziphilayo ze-aerobic kanye ne-carbon dioxide ye-photosynthesis ezitshalweni.
  • Ukwakheka kwamakhemikhali okufanelekile: Iplanethi kufanele ibe nezinhlobonhlobo zamakhemikhali abalulekile ekuphileni, njengekhabhoni, i-hydrogen, i-nitrogen, umoya-mpilo, i-phosphorus nesibabule. Lezi zakhi ziyizingqimba zokwakha zamangqamuzana ezinto eziphilayo njengamaprotheni, ama-nucleic acid, ama-lipids nama-carbohydrate.
  • Amandla anele: Ukutholakala komthombo wamandla kubalulekile. Umthombo oyinhloko wamandla ukukhanya kwelanga, okushayela i-photosynthesis nezinye izinqubo zezinto eziphilayo. Kodwa-ke, kungase kube neminye imithombo yamandla, njengamandla e-geothermal, angasekela izinhlobo zokuphila ezimweni ezimbi kakhulu.
  • Amandla adonsela phansi afanelekile: Amandla adonsela phansi eplanethi kumelwe abe anele ukuze alondoloze umkhathi kodwa angabi namandla kangangokuthi angachoboza izinto eziphilayo.
  • Ukuvikelwa kwemisebe: Insimu kazibuthe esebenzayo ingavikela iplanethi emisebeni ye-cosmic kanye nemimoya yelanga. Ukungabikho kwamandla kazibuthe kungaholela ekulahlekelweni komoya kanye nokuchayeka emazingeni abulalayo emisebe.
  • Ukuzinza ku-orbit: Ukuzinza emzileni weplanethi nokuzungeza kubalulekile ekugcineni isimo sezulu sizinzile. I-axial inclination eyanele kanye nokuzungezisa okungasheshi kakhulu noma okunensayo kusiza ukusabalalisa amandla elanga ngokulinganayo, ukugwema amazinga okushisa aphezulu.
  • Izinsiza zemvelo ezanele: Ukuba khona kwemithombo yemvelo, njengamaminerali nezinhlanganisela zamakhemikhali, kubalulekile ekuthuthukisweni kwanoma iyiphi impucuko yezobuchwepheshe engaba khona.

Ngithemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana nokutholakala kweplanethi entsha enezinga lokushisa elifana neloMhlaba.
