Isingeniso: Ukufuna Iplanethi Enezinja Eziklinayo
Umkhathi uyindawo enkulu futhi engaqondakali, futhi ukufuna ukuphila kwamanye amazwe sekuyisikhathi eside kuyithonya ekuhloleni indawo yonke. Nakuba ososayensi abaningi begxile ekufuneni ukuphila okuhlakaniphile, abanye banesithakazelo sokuthola ngisho nezinhlobo eziyisisekelo zokuphila ngale koMhlaba. Isici esisodwa esinelukuluku salokhu kusesha ithuba lokuthola iplanethi enezinja ezinswininizayo.
Nakuba lokhu kungase kubonakale kuwumgomo oyinqaba wezazi zezinkanyezi nezazi zezinkanyezi, ukuba khona kweplanethi enjalo kungaba nomthelela omkhulu ekuqondeni kwethu indawo yonke kanye nokwenzeka kokuphila ngale kweplanethi yethu. Lesi sihloko sizohlola izici ezihlukahlukene ezihilelekile ekufuneni umhlaba onjalo, okuhlanganisa ukusesha ama-exoplanets angahlalwa, ukuzingelwa kwezilwane zangaphandle nezici zazo, kanye nezimo zemvelo ezidingekayo ukuze kuthuthukiswe impilo.
Ukuhlola Amathuba Okuphila Ngalé Komhlaba
Ukufuna ukuphila ngale koMhlaba kube yinto egxile kakhulu ocwaningweni lwesayensi amashumi eminyaka. Lesi sifiso sigqugquzelwe ukutholakala kwama-exoplanet, amaplanethi angaphandle kwesimiso sethu sonozungezilanga, angase akwazi ukusekela ukuphila. Ososayensi bahlonze izinkulungwane zama-exoplanets, amaningi awo atholakala "endaweni enokuhlalwa kuyo" yenkanyezi yabo, lapho izinga lokushisa lilungile ngokwanele ukusekela amanzi awuketshezi, isithako esiyinhloko sokuphila njengoba siwazi.
Nokho, ukufuna ukuphila ngale koMhlaba akugcini nje ngokuthola amaplanethi endaweni okuhlalwa kuyo. Ososayensi nabo banentshisekelo yokubheka izimpawu zokuphila kwamanye amazwe, njengokuba khona kwamagesi asemoyeni angase akhiqizwe izinto eziphilayo. Ukutholakala kwamagesi anjalo, aziwa ngokuthi ama-biosignatures, kungaba inkomba enamandla yokuba khona kokuphila eplanethini ethile. Ngaphezu kwalokho, ososayensi banesithakazelo ekutholeni ukuphila ezindaweni ezimbi kakhulu, njengokujula ngaphansi kweplanethi noma enyangeni ezungeza umdondoshiya wegesi.
