Nws zoo li koj tau pom lub peev xwm zoo kawg nkaus ntawm James Webb Space Telescope (JWST) los ntawm tam sim no. Qhov kev tshawb fawb thiab kev txawj ntse no txhais tau hais tias ntau npaum li cas rau tib neeg li nws ua rau cov zej zog scientific. Kev txiav txim los ntawm cov neeg tham txog lub tsom iav raj, nws yog qhov tseeb rau kuv tias qhov no yog ib qho ntawm cov sijhawm tshawb fawb uas hla haiv neeg, chav kawm, ciam teb thiab kab lis kev cai marinades. Kuv yog ib tug kws tshawb fawb txog huab cua thiab huab cua tab sis siv ib feem tseem ceeb ntawm kuv txoj hauj lwm ntawm NASA's Goddard Space Flight Center. Lub sijhawm ntawd, kuv tau nrog cov kws tshaj lij cuam tshuam nrog Hubble Space Telescope thiab JWST. Ntau tus neeg tau tham txog qhov txaus ntshai "duab" los ntawm JWST. Technically, lawv yog cov duab. Cia kuv piav.

Honestly, nyob rau hauv lub tswvyim loj ntawm tej yam, kuv yeej tsis muaj teeb meem dab tsi koj hu lawv. Nws yog ib qho tseem ceeb tshaj uas peb txaus siab rau lub ntsiab lus ntawm qhov kev xav ntawm kev tshawb fawb no. Kuv tweeted ua ntej lub limtiam tias cov khoom los ntawm JWST tsis yog hais txog cov duab zoo nkauj xwb, thiab txhawb cov kws tshawb fawb los muab "yog li cas" thaum lawv qhia lawv. Los ntawm kev ua li ntawd, peb tawm tsam qhov kev xav nqaim tawm qhov ntawd uas nug, "Vim li cas peb siv tag nrho cov nyiaj no los thaij duab zoo nkauj ntawm qhov chaw?" Kuv yav dhau los Forbes daim qhia tias vim li cas JWST tseem ceeb rau peb txhua tus.
Raws li tus kws qhia ntawv nrog rau lub platform pej xeem, kuv feem ntau sim qhia cov ntaub ntawv uas koj yuav tsis xav txog. Piv txwv li, cov neeg feem coob muaj kev nkag siab tsis zoo txog qhov "feem pua tej zaum los nag txhais tau tias" (piav qhia no) lossis xav tias xob laim yog ib yam (Nws tsis yog). Raws li kuv tau qhia rau ib tug phooj ywg tsis ntev los no hais tias NASA hais txog qhov koj pom li cov duab thaum nws tshaj tawm txog "cov duab." Kuv kuj pom tau hais tias ib lub sij hawm uas qhia tau zoo tau tsa nws lub taub hau.
Pichalab.com luam tawm xyoo 2022 sau ntawv txoj cai, “Dab tsi yog qhov txawv ntawm daim duab, duab, thiab duab? Raws li tsab ntawv sau, "Hauv cov lus yooj yim, qhov sib txawv ntawm daim duab (luv rau daim duab) thiab daim duab yog tias nws yog lub koob yees duab nws yog daim duab. Ib daim duab ntawm qhov tod tes tuaj yeem yog daim duab ib yam nkaus tab sis kuj yog ib qho duab lossis duab. " Lub sij hawm duab, raws li kev sau ntawv, muaj lub ntsiab lus dav dua. Cov ntawv sau hais mus ntxiv, "Ib qho duab yog qhov pom ntawm qhov muag lossis qhov pom ntawm ib qho khoom, zoo li yog tsim los ntawm kev xav los ntawm daim iav, refraction los ntawm lub lens, los yog qhov kev pom ntawm luminous rays los ntawm qhov me me aperture thiab lawv txais tos ntawm ib qho chaw. ” Los ntawm txoj kev, ib daim duab khaws tseg ntawm koj lub computer yog cov duab.

Khoos phis tawj.com txhais cov duab raws li, "Txhua yam khoom pom uas tau hloov kho lossis hloov kho los ntawm lub khoos phis tawj lossis ib qho khoom xav tau tsim siv lub computer." Ethan Siegel masterfully piav, hauv a Xav Loj sau ntawv, cov duab ua tom qab thawj cov duab tso tawm lub lim tiam no los ntawm NASA. Txhawm rau ua raws li nws cov lus piav qhia ntawm JWST, nws yog ib qho tseem ceeb kom nkag siab tias cov duab ua rau lub koob yees duab qhov chaw no yog cov hauv paus hauv paus hauv electromagnetic spectrum. Raws li NASA website"Electromagnetic zog taug kev nyob rau hauv nthwv dej thiab spans ib tug dav spectrum ntawm lub xov tooj cua ntev heev mus rau luv luv gamma rays." Peb pom nrog peb ob lub qhov muag siv qhov pom (optical) ib feem ntawm qhov electromagnetic spectrum. " Lub Hubble Space Telescope ua haujlwm feem ntau hauv qhov chaw kho qhov muag thiab ultraviolet ntawm lub spectrum whereas JWST siv qhov infrared ntawm lub spectrum. NASA JWST website piav qhia tias thaj av infrared yog qhov muaj txiaj ntsig vim tias, "Tshwj xeeb, cov khoom nyob deb ntau dua yog redshifted ntau dua, thiab lawv lub teeb raug thawb los ntawm UV thiab kho qhov muag mus rau qhov ze-infrared .... kev soj ntsuam ntawm cov khoom nyob deb (zoo li thawj galaxies tsim hauv Lub Ntiaj Teb, piv txwv li) xav tau lub koob yees duab infrared. " Lub ntsiab lus tseem ceeb ntawm no yog tias JWST yog qhov sib ntxiv rau Hubble es tsis yog "hloov pauv," raws li NASA niaj hnub nco ntsoov peb.
Txawm nyob hauv kuv thaj tsam ntawm huab cua, peb siv cov duab satellite uas siv cov khoom siv hluav taws xob los saib xyuas cua daj cua dub, cua daj cua dub, thiab lwm yam huab cua tshwm sim. Peb ib txwm hais txog cov khoom no ua cov duab ib yam nkaus, txawm tias kuv tau hnov cov neeg xa mus rau lawv li duab.
Raws li peb tuaj yeem pom ntawm cov duab no, peb lub qhov muag tsuas pom tau ib feem me me ntawm electromagnetic … [+]
