Whakarāpopototia te tuhinga:  Mo nga whatu arorangi e mau ana ki te Ao, kei raro i te mata o Venus nga kapua matotoru i hangaia i te nuinga o te warowaihā. Hei toro atu ki tēnei arai, ka whakamahia e ngā pūtirotiro pēnei i te waka ā-ao o Magellan te pūtirotiro hei whakaatu i ngā āhuatanga whakaharahara o te aorangi, pēnei i ngā maunga, i ngā kōhao, i ngā puia. Engari ināianei, kua whakakotahihia e ngā kaitātai whetū te Green Bank Telescope me te pūkaha irirangi i te Arecibo Observatory hei hanga i ngā whakaahua tino taipitopito o te mata o te aorangi mai i te Ao. Ko te pikitia he matapae o nga raraunga radar o Venus i kohia i te tau 2012. He ngāwari te kitenga o ngā āhuatanga o te mata, pērā i ngā maunga me ngā pae. Ko te pae tapatapahi pango i te pokapū e tohu ana i ngā wāhi e tata ana ki te paenga ki te whiwhi i ngā raraunga whakaahua pai. Ko ngā tohu pūtirotiro mai i Arecibo i Puerto Rico i haere i roto i te hau o te Ao me te hau o Venus. I konei ka pa ki te mata, ka hoki mai ki te Telescope Green Bank i West Virginia i roto i te tukanga e mohiotia ana ko te radar bistatic. He mea nui tēnei āheinga ki te ako i te mata, ehara i te mea ko te āhua o tēnei wā anake, engari ki te aroturuki hoki i ngā huringa. Mā te whakataurite i ngā whakaahua i tangohia i ngā wā rerekē, e tūmanako ana ngā kaipūtaiao kia kitea i te mutunga ake nei he tohu o te mahi puia. E whakapono ana rātau ka taea hoki e ngā whakaahua pēnei te whakaatu i ētahi atu tukanga matawhenua hihiri e taea ai te whakarato i ngā tohu ki te hītori matawhenua o Venus me ngā āhuatanga o raro. Kua whakaatuhia e nga tohunga whetu Paniora he ariā hou mo te ahua 'Y' i runga i a Venus (ko te whakaahua kua tohua mai i te Pioneer Venus Orbiter i te 1979 e whakaatuhia ana). E kī ana rātau i hangaia e ngā hau e pana ana i tētahi 'ngaru' kapua ki runga i te aorangi. He tere ake te neke o ēnei hau i ngā taumata teitei ake, e waihanga ana i te āhua rerekē. 'He uaua ki te whakataurite i nga whakaahua radar ki te rapu tohu mo te huringa,' e kii ana a Bruce Campbell, he kairangahau matua i te Smithsonian's National Air and Space Museum i Washington,. Kei te haere tonu te mahi. I tēnei wā, ko te whakakotahi i ngā whakaahua mai i tēnei wā me tētahi wā mātakitaki o mua, he nui te mōhiohio e pā ana ki ētahi atu tukanga e whakarerekē ana i te mata o Venus.' Ko Venus he paku...
I tangohia e ngā tohunga whetū ngā whakaahua mā te Green Bank Telescope i West Virginia. I whakakotahitia e rātau tēnei ki te kaiwhakawhiwhi whatu i te Arecibo Observatory. Mā te whakataurite i ngā whakaahua, e tūmanako ana ngā kaipūtaiao kia kitea ngā tohu o te mahi puia. I te wiki kua hipa i whakakitea e ngā kaitātai whetū tētahi ariā hou mō tētahi āhua'Y'i runga i a Venus. E kī ana rātau i hangaia e ngā hau e pana ana i tētahi'ngaru' kapua ki runga i te aorangi.
