Ngā Kitenga Hou o te Ao Tātai: Te Huaki i te Ao Whānui
Ko te whetūrangi tētahi o ngā pūtaiao tino whakamīharo, e hura ana i ngā mea ngaro o te ao whānui me ngā kitenga e miharo tonu ana ngā kaipūtaiao me te marea. Ko ētahi o ngā kitenga hou o tēnei mara, ehara i te mea kua whakarei ake i tō tātou māramatanga ki te ao whānui, engari kua werohia hoki ngā tauira tawhito. Ina koa, i ngā tau tata nei, he maha ngā kitenga whakamiharo kua huri i te huarahi e titiro ai tātou ki te rangi me te wāhi.
1. Te Pōka Pango M101: Te Matatau o te Karu Tirotiro o te Takahanga Horizon
Ka maumaharatia te tau 2019 hei tau i hopukina ai e tātou te whakaahua tuatahi o tētahi pōro pango, nā te Event Horizon Telescope (EHT). Ko tēnei whakaahua o te pōro pango nui rawa atu i waenganui o te tupuni M87 i tohu i tētahi whakatutukitanga whakamiharo i roto i te ao arorangi. Engari kāore i mutu i reira te ahunga whakamua. Nō nā tata nei, i hopukina e te EHT tētahi atu whakaahua o te pōro pango i roto i te tupuni M101, e whakaatu ana i ngā hanganga me ngā tauira taipitopito o ōna tukunga pūngao. He taahiraa nui tēnei ki te mārama ki te tukunga o te pūngao e ngā pōro pango me te pānga ki tō rātou taiao ao huri noa.
2. Ngā Aorangi-ā-Iho: Ngā Ao Hou i te Rohe Ora
Ko te kitenga o ngā aorangi ā-waho, arā, ngā aorangi e porowhita ana i ngā whetū i waho o tō tātou pūnaha rā, tētahi o ngā whanaketanga tino whakahihiri o te ao arorangi o ēnei rā. Nā ngā hangarau me ngā misioni hou pērā i te Kepler Space Telescope me te TESS (Transiting Exoplanet Survey Satellite) kua taea e ngā kaipūtaiao te kimi i ngā mano tini o ngā aorangi ā-waho o ngā rahi me ngā hanganga rerekē. Kei roto i ngā kitenga hou he maha ngā aorangi kei roto i te "rohe noho" o ō rātou whetū, kei reira ngā āhuatanga e āhei ai te wai wai, he mea e hiahiatia ana mō te ora e mōhiotia ana e tātou. Ko tētahi tauira nui ko te kitenga o te aorangi Proxima b e porowhita ana i a Proxima Centauri, te whetū tata rawa atu i muri i te Rā. He rite te taumaha o tēnei aorangi ki a Papatūānuku, ā, kei roto i te rohe noho, e waiho ana hei kaitono matua mō te rapu i te ora mai i waho o te whenua.
3. Ngā Ngaru Ā-Toi: Te Whakarongo ki te Āhua o te Ao Whānui
Ko ngā ngaru tōpana he ngaru i roto i te wā-ātea i puta mai i ngā huihuinga nui o te ao tūroa, pērā i te hanumitanga o te pū pango me te whetu niutron. Mai i te kitenga tuatahi a LIGO (te Laser Interferometer Gravitational-Wave Observatory) i te tau 2015, kua uru tātou ki tētahi wā hou o te arorangi e mōhiotia ana ko te arorangi ngaru tōpana. I te tau 2020, i kitea e LIGO me Virgo te hanumitanga nui rawa atu i waenga i ngā pū pango e rua, i puta ai ngā ngaru tōpana kaha, ā, i homai he māramatanga hou ki te whanaketanga o te ao tūroa. Mā te kitenga o ngā ngaru tōpana ka huaki he matapihi hou mō te tirotiro i ngā āhuatanga arorangi kāore e kitea e ngā karu tiro tikanga, pērā i ngā matua supernova me te hanganga whetu niutron.
4. Ngā Pahūtanga Reo Irirangi Tere (FRB): Ngā Mea Ngaro o te Ao Hōhonu
Ko ngā Pahūtanga Reo Irirangi Tere (FRB) he pupuhi poto engari kaha i roto i ngā ngaru reo irirangi e ahu mai ana i waho o tō tātou tupuni. Mai i tō rātou kitenga i te tau 2007, ko te takenga mai o ngā FRB he mea nui tonu. Heoi, ko ngā hangarau matatau pēnei i te Five-hundred-meter Aperture Spherical Radio Telescope (FAST) i Haina me te Canadian Hydrogen Intensity Mapping Experiment (CHIME) i Kanata kua whakatuwhera i ngā whai wāhitanga hou ki te rangahau i ēnei āhuatanga. Nō nā tata nei, i tautuhia e tētahi rōpū tohunga whetū ngā pūtake o ētahi FRB, ā, i kitea e ahu mai ana i ngā momo tupuni, mai i ngā tupuni pakupaku me te hanganga whetu kaha ki ngā tupuni nui, marino. Mā te rangahau anō i ngā FRB ka āwhina i a tātou ki te mārama ki ēnei āhuatanga tino nui o te ao, me te whakaatu anō hoki i ngā kōrero mō te reo i waenga i ngā whetu e horapa ana rātou.
5. Te Matū Pōuri me te Pūngao Pōuri: Te hura i ngā Mea Ngaro Nui o te Ao
Ko te matū pouri me te pūngao pouri ngā wāhanga nui rawa atu o te ao whānui, e 95% te nui me te pūngao katoa o te ao whānui. Heoi, kāore e kitea tika ana ēnei mea e rua, ā, kāore e taea te tirotiro tika. Kei te whakaratohia e ngā rangahau hou a te Dark Energy Survey (DES) me ngā kaupapa Wilkinson Microwave Anisotropy Probe (WMAP) he māramatanga hou mō te tohatoha me ngā āhuatanga o te matū pouri me te pūngao pouri. Hei tauira, kua whakamahia e te DES ngā tikanga arotahi ā-pūngao ngoikore hei mahere i te tohatoha o te matū pouri me te tino tika. I taua wā tonu, kei te whakapai tonu te tātari raraunga mai i te WMAP i ngā tawhā aorangi e whakahaere ana i te pūngao pouri, e āwhina ana i ngā kaipūtaiao ki te mārama ki tōna tūranga i roto i te tere haere o te horapa o te ao whānui.
6. Te Kitea o ngā Ngota Waro i runga i a Europa me Enceladus: Ngā Tohu o te Ora i runga i ngā Marama Hukapapa?
Ko tētahi o ngā whanaketanga tino whakahihiri i roto i te rapunga mō te ora i tua atu i te Ao ko te kitenga o ngā ngota waro i runga i ngā marama hukapapa o Hūpiter me Hātana, o Europa me Enceladus. E kī ana ngā raraunga mai i ngā misioni a Galileo me Cassini kei roto i ēnei aorangi ngā moana i raro i ō rātou mata hukapapa, ā, tera pea he āhuatanga pai mō te ora o ngā moroiti. Nō nā tata nei, kua whakakitea e te tātaritanga raraunga te aroaro o ngā matū waro me ngā ngota matatini pērā i te methane me te ethane i roto i ngā pupuhi wai me te hukapapa i tukuna mai i te mata o Enceladus. Ka ara ake tēnei i te tūponotanga kei te puta ngā tukanga koiora i roto i ngā moana o raro i te mata o ēnei marama, ka whakarato i te hihiri hou mō ngā misioni ā muri ake nei e aro ana ki te tūhura atu i a rātou.
Whakamutunga
Ko ia kitenga hou i roto i te ao whetū, ehara i te mea ka hohonu ake tō tātou māramatanga ki te ao tūroa, engari ka ara ake anō hoki ngā pātai hou ka roa pea te whakautu. Mai i ngā pōro pango ki ngā aorangi nohoia, mai i ngā ngaru ā-papa ki ngā Pakūnga Reo Irirangi Tere, ka huaki i ia kitenga he matapihi ki tētahi ao whānui ake, he ao uaua ake i tā tātou i whakaaro ai. Mā te hangarau e whanake tonu ana me te wairua tūhura e kore e memeha, ka mārama ake, ka nui ake te tumanako o te heke mai o te whetū. Ehara i te mea ko te mārama ki te wāhi kei reira tātou anake te tūhuratanga o ngā rangi, engari ko te rapu whakautu ki ngā pātai matua mō ngā takenga mai me te mutunga o te ao tūroa.
