Whakarāpopototia te tuhinga:  Kua kitea e ngā kairangahau te mea ngaro o te kāhua tae 'ngaro' o Mercury. E kī ana rātau, nā te puehu pūmau o te waro mai i ngā whetū e haere ana i mua, i pōuri pōuri ai a Mercury i roto i ngā piriona tau. Ka whakaoti i te mea ngaro o te tae rerekē o Mercury - nāna i pōhēhē ngā pūtaiao. E kī ana rātou, nā te puehu pūmau o te waro mai i ngā whetū e haere ana, i āta whakakikoruatia a Mercury ki te kākahu pōuri 'ngaro' i roto i ngā piriona tau. Ko te puehu o te komete e 25 ōrau te taumaha o te waro, nō reira ka pā tonu a Mercury ki te pupuhi waro mai i ēnei komete pakaru. Mā te whakamahi i tētahi tauira o te tukinga pānga me tētahi tātaitanga mōhiotia o te rere o te micrometeorite i Mercury, ka whakaarohia e ngā kairangahau i muri i te piriona o nga tau o te whakaeke, ko te mata o Mercury me waiho i hea i te 3 ki te 6 ōrau waro. 'Kua roa te whakapae kei reira tetahi kaihoko pouri ngaro e whai waahi ana ki te whakaata iti o Mercury,' e kii ana a Megan Bruck Syal, he kairangahau postdoctoral i te Lawrence Livermore National Laboratory nana i mahi tenei rangahau i a ia e ako ana i te Whare Wananga o Brown. 'Ko tētahi mea kāore i whakaarohia ko te nui o ngā rauemi i ahu mai i ngā kōmiti e tukuna ana ki runga i a Mercury.' I te toharite, he pōuri rawa a Mercury i tōna hoa tata, te Marama. E mōhiotia ana ko ngā tinana kore hau e pōurihia ana e ngā pānga micrometeorite me te whakaeke o te hau rā, he tukanga e waihanga ana i tētahi paparanga angiangi o ngā nanoparticles rino pōuri i runga i te mata. Engari ko ngā raraunga ā-arorangi mai i a Mercury e tohu ana he iti rawa te rino nanophase i runga i tōna mata, ehara i te mea nui ki te whakamārama i tōna āhua pōuri. I te whakatata atu o ngā whetū ki te taha o Mercury e tata ana ki te rā, ka tīmata pinepine rātau ki te wehewehe. Ko te puehu o te komete e 25 ōrau te taumaha o te waro, nō reira ka pā tonu a Mercury ki te pupuhi waro mai i ēnei komete pakaru. Mā te whakamahi i tētahi tauira o te tukunga pānga me tētahi tātaitanga mōhiotia o te rere o te micrometeorite ki Mercury, i taea e Bruck Syal te whakatau tata i te auau o te pānga o te rauemi cometary ki Mercury, te nui o te waro ka...
Ko te puehu o te waro mai i ngā whetū e haere ana kua pōuri ake a Mercury. Ko te mata o Mercury kei waenganui i te 3 ki te 6 ōrau te waro. Kua hoatu e te aorangi he ahua pango tata.
