Whakarāpopototia te tuhinga:  (CNN) Ko tātau anake i te ao nui? Tērā pea kei tētahi atu wāhi rānei te ora mohio? I te wiki kua hipa, i kōrero ngā kaipūtaiao o NASA i roto i ngā kupu tino pūmau i ngā kaupae ki te tūhura i te ora i ētahi atu wāhi i te ao nui i roto i te tekau tau, e rua rānei e whai ake nei. I tēnei tau ko te 20 tau o te kitenga o tētahi aorangi e karapoti ana i tētahi whetū pērā ki tō tātou rā, 51 Pegasi. Mai i taua wā, kua kitea e ngā rangahau i runga i te whenua me te amiorangi Kepler a NASA tata ki te 2,000 ngā "exoplanets" kua whakapumautia, ā, he mano anō ngā kaitono e tatari ana ki te whakapumautanga. He maha o ēnei pūnaha aorangi e tino rerekē ana i tō tātou pūnaha rā. Ko ētahi he aorangi nunui, pēnei i a Hupita, e huri ana i ō rātou whetū, e tata atu ana i a Mercury, te aorangi o roto rawa o tō tātou pūnaha rā. Engari he uaua ake te kimi i ngā aorangi toka iti iho pēnei i te Ao, engari he nui ake. I whanake te ora i runga i te Ao i roto i ona moana tata ki te piriona tau i muri i te hanganga o te aorangi. E tohu ana tērā i ngā aorangi toka me te wai wai i runga i o rātau mata, tērā pea i tipu ake ngā momo oranga taketake. Ko te ora e mōhiotia ana e tatou he mea hangai ki te waro, ā, me whai wai wai. E tautuhia ana e nga tohunga whetu te "rohe noho" huri noa i te whetu hei rohe e taea ai te wai wai te noho i runga i te mata o te aorangi. Ki te whakatata atu te whetū, ka kohua te wai hei korohū; ki te tawhiti ake, ka hukapapa te wai hei huka. I runga anō i ngā kitenga i kitea i tēnei wā, e whakaaro ana ngā tohunga whetū he 40 piriona pea ngā aorangi rite ki te Whenua, e nohoia ana i roto i to tatou Milky Way anake. Ko te tikanga, he rerekētanga kei waenganui i ngā rauropi pūtau kotahi -- i whakawhanakehia i te 3.8 piriona tau ki muri, ā, i noho tonu hei momo oranga tino matatau mō ētahi atu piriona tau rānei -- me ngā whāngote, i puta mai i te 200 miriona tau ki mua. Na ko te tangata, e 200,000 noa iho nei ona tau i ora ai. Ko te oranga mohio e taea ana te whakawhitiwhiti kōrero mā ngā ngaru irirangi me ētahi atu oranga mohio he iti iho i te 100 tau te pakeke i konei i runga i te Ao. Na ahakoa ko ngā aorangi e whakawhanake ana i ngā momo oranga ohie, he tekau mā rua pea, ko te tokomaha o ngā mea ora hei whakawhiti kōrero ki a rātou - ahakoa i whakaaro rātou i whanake hei tangata...
E kōrero ana ngā kaipūtaiao o NASA i ngā kaupae ki te kimi ora i ētahi atu wāhi i te ao nui i roto i ngā tau e rua tekau e whai ake nei. Meg Urry: Ko te ora i ētahi atu wāhi o te ao nui, tae atu ki ētahi atu wāhi i roto i to tatou ake aorangi Milky Way, he mea kore e taea te karo. Engari he iti noa iho te tūponotanga ka taea e tātou te kōrero ki taua oranga, e tuhituhi ana ia.
