James Webb Space Telescope (JWST) ka tino tohunga ki te arorangi infrared ki te ako moata ao. Ka rapua e ia nga tohu whatu/infrared mai i te timatanga whetu me nga tupuni i hanga i roto i te Te ao i muri tata mai i te Big Bang kia pai ake te mohio ki te hanganga me te whanaketanga o nga tupuni me te hanganga o whetu a te ao pūnaha. JWST ka ako ano te ao nga punaha me nga takenga mai o te oranga. Ko te tino tatari JWST kua whakaritea inaianei hei te 18 Hakihea 2021.
I te nuinga o te wa, ka arotahi tetahi i te karu karu ki tetahi whaainga hei mataki. Engari i etahi wa ka aro nui koe ki tetahi mea ka huri ke te huarahi o tetahi waahi ako. Te whakatau ki te arotahi He whakaheke wāhi Ko te telescope i runga i tetahi mea i nga mara kaore ano kia tirotirohia i te rangi tetahi o nga mea i puta ke te huarahi o te aorangi.
I roto i te maha o nga whakatutukitanga o He whakaheke mokowā Telescope (HST), ko nga whakaahua hohonu i tangohia i roto i nga ra 10 i te tau 1995 i hopukia e ia tata ki te 3000 nga ahua o nga tupuni i nga waahanga rereke o te kukuwhatanga whetu kua huri i te aorangi me te whakarereke i to maatau mohio ki te ao.
Ko enei whakaahua hohonu i hangaia e te marama i haere mai i nga waahi tawhiti o te ao mo nga piriona tau marama i roto i te whakawhānui ao a kua tae ki te whenua inaianei kia hopukina e te He whakaheke telescope i muri i te tuatahi i puta mai i te timatanga whetu me nga tupuni i hanga i muri tata mai i te Big Bang tata ki te 13 piriona tau ki muri. Na, i te mea ko nga whakaahua mara hohonu i tohu wawe whetu me nga tupuni pera i tera wa e hia piriona tau ki muri. He tino mahi whakamiharo tenei.
Engari, ko tenei tikanga mo te hopu i nga tohu mata o mua hei whakawhanake i te maarama moata ao Kaore pea he taputapu tikanga whai hua na te mea i kitea i te tau 1929 e Edwin He whakaheke e te ao kei te whakawhānui ake, kei te neke atu nga tupuni katoa i a raatau ano e kitea ana e te nekehanga whero o tupuniTe tuāwhiorangi ki nga roangaru teitei ake i te rohe infrared (IR). Engari ko te He whakaheke kua rite rawa te telescope ki te mataki i roto i te UV, te rohe kitea me te tata-infrared no reira te hiahia mo te infrared motuhake. mātakitaki in wāhi.
te James Webb Space Telescope (JWST) he riiwhi mo te He whakaheke wāhi telescope (HST) in the sense that the Hemi Webb Ko te whainga telescope ki te kawe whakamua i te He whakaheke tuku iho o te telescope i roto i te waahi o te ako moata ao. JWST ka mahi anake i roto i te arorangi infrared me te whai i nga whainga matua e wha:
Mo enei take, JWST me rereke mai He whakaheke telescope i roto i te hoahoa me te mahi. He karu whakaata whakaata i hangaia hei hopu i nga iraruraru tata-infrared mai i nga mara hohonu me te whakaata ahua origami nui e 100 nga wa kaha ake i te He whakaheke. I roto i te meka, JWST ko te nui rawa wāhi telescope tonu. Ki te pupuri i tona tairongo infrared kore i mua, JWST he whakamarumaru mai i te pokenga infrared mai i te ra na roto i te parepare 5-apa tino whai hua. I tua atu, hei awhina ki te pupuri i te iti rawa o te pāmahana whakahaere o te 50 Kelvin (-223° C, -370° F), ka whakanohohia a JWST ki roto pati huri noa i te ra i roto i te atarangi makariri o Papa i nga wa katoa e tata ana ki te pito tuarua o Lagrange (L2) o te punaha Whenua-Ra i te tawhiti tata ki te 1.5 miriona kiromita mai i te Papa.
Te whakanohonga o JWST tata ki tawhiti atu i te punaha Sun-Earth L2 pati tikanga, rereke He whakaheke telescope i whiwhi e rave rahi whakatikatika me te tiaki i roto i te wāhi, JWST ka noho noa i muri i te whakarewatanga na reira kaore he waahi o tetahi hapa. Ko tenei pea ka whakamarama he aha te whakarewatanga o JWST kua tata roa tonu.
Na, JWST kua whakaritea kia whakarewahia a te 18 Hakihea 2021.
I te 02 o Noema 2021, JWST kua tae marie atu ki tana waahi whakarewatanga i French Guiana, a kei te whakarite te roopu hangarau mo te hiki i te 18 o Hakihea.

 will specialise exclusively in infrared astronomy to study early universe. It will search for optical/infrared signals from the early stars and galaxies formed in the Universe soon after the Big Bang for a better understanding of the formation and evolution of galaxies and the formation of stars and planetary systems. JWST will also study planetary systems and the origins of life. The much-awaited JWST is now scheduled to be launched on 18 December 2021. ){kind=link}
