Kwemakumi emakore, panzvimbo pekufunganya zvakanyanya kushingairira kuchengetedza nyika yatinogara mumamiriro akakwana, sainzi yakada tsvaga dzimwe nyika uko hupenyu hunogoneka, angave mapuraneti asina chinhu anogona kugarwa nevanhu (uye kushandisa), kana mapuraneti ane hupenyu hwekunze uye isu tinogona kukunda.
Muna 2009, NASA's Kepler space mission yakatanga nechinangwa chekupindura zvakanyanya Taura: "Ndeapi mapuraneti akafanana nepasi Pasi aripo mugirazi?" Mushure memakore masere ekutsvaga, isu tatova nemhinduro yekutanga.
Mapuraneti gumi matsva akawanikwa kutsvaga hupenyu
Iyo Kepler yakakosha nzvimbo mamishinari timu, mushure memakore masere ekushanda nesimba, yatotaridza izvo, zvenguva, izvo katarogu yakakura ye kugona mapuraneti matsva. Kunyanya, iyi runyorwa inoumbwa neiyo yakazara ye 219 zvakawanikwa, asi havazi vese vanoshanda kuti vagamuchire hupenyu.
Pazvinhu zvese izvi zvakawanikwa, gumi dzazvo dzine zvimiro zvakaenzana chaizvo nehukuru hwepasi redu, kuwedzera pakuva nenzira yakatenderera. Chii chimwe, inogona kuvapo nepo ivo vari mukati meinonzi "nzvimbo yekugara", ndiko kuti, ivo vari kure zvakakwana kubva kuzuva kuti vagadzire mvura munzvimbo ine mvura, yakakosha pahupenyu.
Mario Pérez, nhengo yeKepler mishoni yeNASA yeAstrophysics Division, ndiye aive nebasa rekuburitsa pachena. ruzivo urwu Nezuro chete kubva kuSilicon Valley. Nezviwanikwa izvi makumi maviri nezviviri, vatove Vadzidzi ve4.034 vakawanikwa. Pakati pavo vese, zvakatosimbiswa kuti 2.335 vari kunze kwenzvimbo yedu yezuva (ivo, saka, exoplanets), nepo vangangosvika makumi matatu vari padyo nepasi redu.

Sezvaunogona kufungidzira, iyo yekuisira satellite Kepler anoenderera mberi nekutenderera Zuva kuti riite basa raro rekutsvaga mapuraneti matsva anokwanisa kugashira hupenyu uye kuburitsa data nyowani neruzivo zvinotibvumidza kuti tinzwisise zvirinani zvakasikwa.
Kana vachitaura nezvekunze kwenyika zvakafanana nekunzwa mumwe munhu achiti ndaona denga naMwari, manyepo makuru maviri evanhu ?????
