I roto i te ono piriona tau mai i tenei wa, ka tukituki to tatou tupuni kainga Milky Way (MW) me te tupuni Andromeda (M 31) e tata ana, ka hanumi tetahi ki tetahi ka puta he tupuni elliptical hou. Koinei te maaramatanga o naianei mo te heke mai o to tatou tupuni kainga Milky Way. Heoi, ma te whakamahi i nga raraunga mai i nga tirohanga hou a nga karu mokowhiti a Gaia me Hubble, kua kitea e nga kairangahau ko te tukinga Milky Way-Andromeda he iti rawa te kore e taea. Ko nga tupuni e rua karekau pea e hanumi, a ko te tupono "kare he Milky Way–Andromeda hanumi" he tata ki te 50 %.
Ka ahatia ki te Ao, ki te Ra me to tatou tupuni kainga a muri ake nei? E kore ratou e mau tonu ake ake. Ka noho nohoia te whenua mo etahi atu 4 piriona tau ki te kore e whakangaromia i mua e te tangata, i nga aitua taiao ranei penei i te pakanga karihi, te huringa o te rangi, te paheketanga o te asteroid, te pahūtanga nui o te puia, me etahi atu. Ko te kaha ake o te pehanga na te tiango o te matua ka puta te whakakotahitanga karihi o nga mea taumaha i roto i te matua. Ko te mutunga mai, ka piki ake te mahana o te Ra, ka toro atu te paparanga o waho o te hau o te ra ki waho o te mokowhiti, ka kapi i nga aorangi tata tae atu ki a Papa. Ka haere tonu tenei wahanga nui whero mo te kotahi piriona tau. I te mutunga, ka hinga te Ra ki te papaka ma.
Mo to tatou tupuni kainga Milky Way (MW), ko te maaramatanga o naianei ko te kunenga mai o te Roopu Rohe (LG) kei roto neke atu i te 80 nga tupuni tae atu ki nga tupuni torino nui e rua Milky Way (MW) me te Andromeda galaxy (M 31) ka peia e te hihiri o te Milky Way me te punaha tupuni Andromeda. I roto i te wha piriona tau mai i tenei wa, ko te tupuni tata o Andromeda kei te 2.5 miriona tau marama te tawhiti ka tukituki ki to tatou tupuni kainga i te 250,000 mph. E whakaponohia ana kua timata pea te mahi, a kei te tutuki tonu nga tupuni e rua. Ka roa te tukinga mo te 2 piriona tau, ka mutu ka hanumi nga tupuni e rua i roto i te ono piriona tau mai i naianei ka puta he tupuni elliptical hou. Ka ora te punaha solar me te Ao i te whakakotahitanga engari ka whai taunga hou ki te waahi.
Te ahua nei he whakaaro i waenganui i nga tohunga mo te tukinga me te whakakotahitanga o Milky Way me nga tupuni Andromeda e tata ana ki te Roopu Rohe. E whakaponohia ana ka hanumi te tokorua nei ki a raua ano a muri ake nei ka puta he tupuni whakakotahi. Heoi ano, ko te rangahau hou e kii ana kaore pea te tukinga e kore e taea.
Ma te whakamahi i nga raraunga mai i nga tirohanga hou a nga karu mokowhiti a Gaia me Hubble, i tirotirohia e nga kairangahau ka pehea te tipu o te Roopu Rohe i roto i nga tau 10 piriona e whai ake nei. I kitea e ratou ko etahi atu tupuni nui e rua i roto i te Roopu Rohe ara ko M33 me te Kapua Magellani Nui e awe nui ana i te omiowao Milky Way–Andromeda. I tua atu, ko te amionga o te Kapua Magellani Nui e rere tika ana ki te amionga Milky Way–Andromeda ka iti ake te tukinga me te hanumi o Milky Way me Andromeda. I kitea e nga kairangahau ko te tukinga Milky Way-Andromeda he iti rawa te kore e taea. Ko nga tupuni e rua karekau pea e hanumi, a ko te tupono "kare he Milky Way–Andromeda hanumi" he tata ki te 50 %.

 and the neighbouring Andromeda galaxy (M 31) will collide and merge with each other giving rise to a new combined elliptical galaxy. This is the current understanding about future of our home galaxy Milky Way. However, using data from the latest observations by the Gaia and Hubble space telescopes, researchers have found that Milky Way-Andromeda collision is far less inevitable. The two galaxies may not necessarily merge and the probability of “no Milky Way–Andromeda merger” scenario is close to 50 %.){kind=link}
