Whakarāpopototia te tuhinga:  E kii ana nga kaiputaiao kua kitea e ratou e 50 nga tupuni e mau ana pea i nga iwi mohio o waho. I kitea ēnei aorangi e tuku ana i ngā taumata <unk>nui whakaharahara<unk> o te radiation - tērā pea e tohu ana i te <unk>te aroaro o tētahi iwi tino matatau.<unk> I roto i ēnei aorangi, e ai ki ngā kairangahau, tērā pea kei te whakamahi tētahi iwi kē i te mana o ngā whetū - e tuku ana i te nui o te wera e kitea ana i roto i te tukanga. Kua kitea e ngā pūtaiao o Pennsylvania he tohu kāore pea tātou i te noho mokemoke. I kitea e rātau e 50 ngā aorangi e tuku ana i ngā taumata teitei o te radiation. Tērā pea nā te mea kei te whakamahi i te mana o ngā whetū ngā tāngata ke. Heoi, me rangahau anō kia whakapumautia ai tērā. E whakaaturia ana ko Arp 220, tētahi kaitono aorangi whakaari. I arahina te rangahau e Dr Jason Wright mai i te Center for Exoplanets and Habitable Worlds i te Whare Wānanga o Penn State i Pennsylvania. Ko te Heat Glimpsing from Alien Technologies Survey (G-Hat), i whakaputaina i roto i te Astrophysical Journal, he taipitopito me pehea te whakaaro o te roopu ka kite pea ratou i te waitohu infrared o te iwi he nui ake te ahu whakamua i a tatou. Ko tētahi tikanga kua whakaarohia hei whakamahi i te mana o tētahi whetū katoa, e mōhiotia ana ko te ao Dyson. I whakaarohia tuatahitia e te tohunga ahupūngao ariā a Freeman Dyson i te tau 1960, koinei pea te tini o ngā amiorangi e karapoti ana i tētahi whetū. Tērā pea he anga kati, he waka ā-ao rānei kua horahia ki te kohikohi i tōna pūngao - e mōhiotia ana ko te ngaru a Dyson. Mēnā kei te tīariari aua hanganga, ka tukuna mai e rātau he nui o ngā hihi pōkākā e kitea ana ki te Ao. Engari, kāore anō kia kitea he hanganga pēnei. Pūtake: All About Space magazine. "Ko te whakaaro kei muri i ta maatau rangahau, mena he tupuni katoa i nohoia e tetahi iwi whakatipu mokowhiti matatau, ko te kaha i hangaia e nga hangarau o taua iwi ka kitea i roto i nga roangaru o waenga-whero", e kii ana a Dr Wright. Ko te pūngao e whakamahia ana e taua iwi kia kitea ai, he nui rawa - ka taea pea te whakamahi i te mana o nga whetu o te tupuni. Engari i kī a Tākuta Wright e kī ana te pūngao pāmahana taketake ki a tātau me rere tēnei pūngao...
