Getting to Know Various Space Telescopes
Mulengalenga—malire omaliza—malo aakulu omwe akupitirizabe kudabwitsa anthu ndi zinsinsi ndi zodabwitsa zake. Kumvetsetsa kwathu chilengedwe chopanda malire ichi kwakulitsidwa kwambiri ndi ma telescope a mumlengalenga, omwe asintha kwambiri zakuthambo. Zipangizo zamakono izi, zomwe zimazungulira pamwamba pa zosokoneza zomwe zimachitika chifukwa cha mlengalenga wa Dziko Lapansi, zimatipatsa kumveka bwino komanso kuzama m'mawonedwe awo. Nayi kuwunika kwakuya kwa ma telescope ena otchuka kwambiri a mumlengalenga omwe akulitsa madera athu.
The Hubble Space Telescope
Palibe kukambirana za ma telesikopu amlengalenga komwe kungakhale kokwanira popanda kutchula Hubble Space Telescope (HST) yolemekezeka. Yoyambitsidwa mu 1990 ndi NASA, Hubble imazungulira pafupifupi makilomita 547 pamwamba pa Dziko Lapansi. Ngakhale kuti inali ndi zovuta zaukadaulo poyamba, telesikopu yakhala imodzi mwa zida zasayansi zopindulitsa kwambiri zomwe zidapangidwapo.
Pokhala ndi galasi loyambirira la mamita 2.4 ndi zida zosiyanasiyana zasayansi, Hubble imachita bwino kwambiri pojambula zithunzi zapamwamba kwambiri mu mafunde owoneka, a ultraviolet, komanso afupi ndi infrared. Zomwe zapezeka zakhala zazikulu kwambiri, kuyambira kapangidwe kake ka milalang'amba mpaka kuzindikira mapulaneti akunja. Zithunzi za Hubble Deep Field, zomwe zikuwonetsa milalang'amba zikwizikwi mu chimango chimodzi, zasintha kumvetsetsa kwathu kukula ndi zaka za chilengedwe chonse.
Hubble nthawi zonse imatumiza zithunzi ndi deta yodabwitsa yomwe imalimbikitsa mapulojekiti ambiri ofufuza, kutithandiza kuphunzira zinthu monga mabowo akuda, ma nebulae, ndi kuchuluka kwa kukula kwa chilengedwe chonse. Cholowa chake mosakayikira chidzakhudza ntchito zamtsogolo zakuthambo.
The James Webb Space Telescope
Kampani ya James Webb Space Telescope (JWST) yomwe ikukonzekera kulowa m'malo mwa Hubble, ndi pulojekiti yayikulu yokonzekera kupititsa patsogolo malire a kuyang'ana mlengalenga. Yotchedwa dzina la James E. Webb, woyang'anira NASA yemwe adachita gawo lofunika kwambiri mu ntchito za Apollo, JWST ndi mgwirizano wa NASA, European Space Agency (ESA), ndi Canadian Space Agency (CSA).
JWST, yomwe idakonzedwa kuti iyambe kugwiritsidwa ntchito mu Disembala 2021, ili ndi galasi loyambira la mamita 6.5, lalikulu kwambiri kuposa la Hubble, zomwe zimapangitsa kuti likhale ndi mphamvu zambiri zosonkhanitsa kuwala. Lapangidwa kuti liziwona mu infrared spectrum, zomwe zimathandiza kuti lizitha kuwona mitambo ya fumbi la cosmic ndikujambula zithunzi kuchokera ku chilengedwe choyambirira. Asayansi akuyembekeza kuti JWST ithandiza kuvumbulutsa zinsinsi zokhudza kupangidwa kwa nyenyezi ndi milalang'amba, kupititsa patsogolo kumvetsetsa kwathu kwa mapulaneti, komanso mwina kupeza zizindikiro zokhudza chiyambi cha moyo.
Kapangidwe katsopano ka JWST kakuphatikizapo chishango cha dzuwa chofanana ndi bwalo la tenisi kuti chiteteze zida zake ku kuwala kwa dzuwa, kuonetsetsa kuti kutentha kuli bwino. Telesikopu iyi idzayikidwa pamalo achiwiri a Lagrange (L2), pafupifupi makilomita 1.5 miliyoni kuchokera ku Dziko Lapansi, zomwe zimathandiza kuti iwonetse bwino chilengedwe chonse.
The Chandra X-ray Observatory
Ngakhale kuti Hubble amaona kuwala kooneka, Chandra X-ray Observatory imayang'ana kwambiri pa ma X-ray, zomwe zimapatsa chithunzithunzi china cha chilengedwe. Chandra, yomwe idayambitsidwa mu 1999, imagwira ntchito mozungulira kwambiri, kufika mtunda wa makilomita 139,000 kuchokera ku Dziko Lapansi. Malo owonera awa amalola kuti ipewe kusokonezedwa ndi mlengalenga wa dziko lapansi womwe umajambula ma X-ray.
Dzina lake lochokera kwa Subrahmanyan Chandrasekhar, yemwe adapambana mphoto ya Nobel, limapangitsa kuti Chandra igwire ntchito yotulutsa mpweya wa X-ray kuchokera kumadera otentha a chilengedwe chonse, monga zotsalira za nyenyezi zomwe zaphulika, magulu a milalang'amba, ndi zinthu zomwe zikuzungulira mabowo akuda. Kupeza kwake kwakhala kofunikira kwambiri pomvetsetsa njira zamagetsi zomwe zimapanga chilengedwe.
Mwachitsanzo, Chandra wapereka chidziwitso cha mtundu wa zinthu zakuda mwa kuphunzira za kugundana pakati pa magulu a milalang'amba ndipo wathandiza kuthetsa chinsinsi cha zinthu zomwe zikusowa m'chilengedwe chonse. Malo owonera zinthu awa akupitirizabe kuwonjezera ma telesikopu ena, kuwonetsa chithunzi chokwanira cha mphamvu zomwe zikuchitika m'chilengedwe chathu.
The Spitzer Space Telescope
Spitzer Space Telescope, yomwe idakhazikitsidwa mu 2003, ndi katswiri wodziwa bwino za infrared, zomwe zimathandiza kuti ione kupitirira mawonekedwe owoneka omwe amabisika ndi fumbi la chilengedwe. Dzina lake lochokera kwa Lyman Spitzer, yemwe ndi wolimbikitsa kwambiri ma telescope amlengalenga, Spitzer yapereka kumvetsetsa bwino madera ozizira komanso afumbi amlengalenga.
Mphamvu zake za infrared zinathandiza akatswiri a zakuthambo kuphunzira zinthu monga kupangika kwa nyenyezi, kapangidwe ka milalang'amba, ndi mlengalenga wa ma exoplanets. Spitzer adathandiza kwambiri kupeza dongosolo la TRAPPIST-1, nyenyezi yapafupi yomwe ili ndi ma exoplanets asanu ndi awiri akuluakulu a Dziko Lapansi, atatu mwa iwo ali m'dera lokhalamo anthu.
Ngakhale Spitzer inasiya kugwira ntchito mu 2020 itatha choziziritsira chomwe chimagwiritsidwa ntchito pazida zake zodziwika bwino, zopereka zake zimapitilirabe kudzera m'zosungiramo zambiri zamtengo wapatali.
The Kepler Space Telescope
Podzipereka kupeza mapulaneti ofanana ndi Dziko Lapansi, Kepler Space Telescope, yomwe idakhazikitsidwa mu 2009, yasintha kwambiri pakupeza mapulaneti. Pogwiritsa ntchito njira yoyendera, Kepler adayang'anira kuwala kwa nyenyezi zoposa 150,000, kuzindikira kutsika pang'ono komwe kumachitika chifukwa cha mapulaneti omwe amadutsa patsogolo pawo.
Zomwe Kepler anapeza zakhala zatsopano kwambiri. Zatsimikizira mapulaneti opitilira 2,600, zomwe zakulitsa kwambiri chidziwitso chathu cha kusiyanasiyana kwa machitidwe a mapulaneti ndi kufalikira kwawo. Kepler wasonyeza kuti mapulaneti akuluakulu a Dziko Lapansi ndi ofala m'malo okhala nyenyezi zawo, zomwe zikusonyeza kuti chilengedwe chonse chikhoza kukhala ndi maiko okhalamo.
Ngakhale ntchito yake yayikulu itatha mu 2013 chifukwa cha mavuto a makina, Kepler adapitiliza kugwira ntchito mu ntchito ya K2, kupititsa patsogolo kusaka kwathu mapulaneti akunja ndikuphunzira zochitika zosiyanasiyana zakuthambo mpaka pomwe idasiya kugwira ntchito mu 2018.
The Fermi Gamma-ray Space Telescope
Chida cha Fermi Gamma-ray Space Telescope, chomwe chidayambitsidwa mu 2008, chomwe chidatchedwa dzina la katswiri wa sayansi ya zamoyo Enrico Fermi, chimayang'ana kwambiri zochitika zamphamvu kwambiri m'chilengedwe chonse. Mwa kuwona kuwala kwa gamma, Fermi amapereka chidziwitso pa zochitika monga supernovae, nyenyezi za neutron, ndi kuphulika kwa gamma-ray.
Zinthu zodziwika bwino zomwe zapezeka zikuphatikizapo kuzindikira thovu la gamma-ray lomwe limachokera pakati pa Milky Way, lomwe limaganiziridwa kuti linachokera ku zochitika zakale zamphamvu pakati pa mlalang'amba wathu. Zomwe Fermi adawona zakhala zofunikira kwambiri pophunzira kuwala kwamphamvu kwambiri kwa chilengedwe komanso kupititsa patsogolo kumvetsetsa kwathu za zinthu zakuda.
Conclusion
Ma telesikopu a mumlengalenga mosakayikira asintha kwambiri kumvetsetsa kwathu za chilengedwe. Kuyambira pazithunzi zodabwitsa za Hubble mpaka zomwe Kepler adapeza ku exoplanet komanso zopereka zomwe JWST idayembekezera, zida izi zakulitsa chidziwitso chathu ndikutsegula njira zatsopano zofufuzira. Pamene ukadaulo ukupita patsogolo, ma telesikopu a mumlengalenga amtsogolo adzapitiriza kuulula zinsinsi za chilengedwe chonse, kulimbikitsa anthu kuti afike kutali ndi nyenyezi ndikuyankha mafunso osatha okhudza komwe tidachokera komanso malo athu mu chilengedwe.
