Muhimmancin Nancy Grace Roman Space Telescope

An shirya ƙaddamar da na'urar hangen nesa ta sararin samaniya ta Nancy Grace (wanda aka fi sani da na'urar hangen nesa ta Roman) zuwa sararin samaniya a ranar 30 ga Agusta, 2026. Za a sanya shi a cikin kuma yana aiki daga zagaye mai kusurwa huɗu a kusa da wurin Lagrange na biyu na Rana-Duniya (L2) a kusa da na'urar hangen nesa ta sararin samaniya ta James Webb (JWST) a nisan kilomita miliyan 1.5 daga Duniya. An keɓe shi don nazarin abubuwa masu duhu, makamashin duhu, da kuma duniyoyin waje, na'urar hangen nesa ta Roman za ta gudanar da manyan bincike na taurari sama da biliyan ɗaya da tarin taurari waɗanda ke zana taswirar rarrabawa da juyin halittar abu da kuma auna tarihin faɗaɗa duniya. Wannan zai ba da ra'ayi game da tasirin abubuwa masu duhu da makamashin duhu akan siffofi da rarraba taurari da tarin taurari a cikin sararin samaniya. Zai lura da supernovae na Type Ia mai nisa, waɗanda ke aiki a matsayin alamun faɗaɗawar sararin samaniya don siffanta makamashin duhu. Ta amfani da na'urar microlensing, hoton kai tsaye, da transit, Roman zai kuma bincika da kuma nazarin exopplanets kuma ana sa ran zai bayyana sama da exopplanets 100,000 yayin da suke wucewa ta taurarin masu masaukin baki. Roman zai ɗauki manyan hotuna kuma zai ba da babban hoto, yayin da James Webb Telescope ke yin manyan abubuwan lura da ke gani a baya tare da ƙuduri mafi girma. Tare za su iya zama babban taimako a nazarin ilmin taurari.

Sararin gani da ido

Lyman Spitzer ne ya gabatar da ra'ayin na'urar hangen nesa mai amfani da sararin samaniya a shekarar 1946. An yi tunanin cewa abubuwan da na'urar hangen nesa da ke cikin sararin samaniya ta yi ba za su kasance ba tare da wani karkacewa da yanayin duniya mai cike da rudani ya haifar ba. Haka kuma, zai yiwu na'urar hangen nesa ta sararin samaniya ta kalli hasken UV, X-ray, da raƙuman infrared waɗanda ƙwayoyin iska ke sha a sararin samaniya. Tashar hangen nesa ta Astronomical Observatory 2 (OAO-2), wacce aka fi sani da Stargazer, ita ce na'urar hangen nesa ta farko da ta yi nasara a sararin samaniya wadda ta yi abubuwan lura a cikin kewayon UV. An harba ta a shekarar 1968 kuma ta ci gaba da aiki har zuwa 1973. 

Taswirar Hubble Space Telescope wataƙila ita ce na'urar hangen nesa mafi shahara a sararin samaniya. Babban na'urar hangen nesa ce kuma an ƙaddamar da ita a shekarar 1990. Tana da nisan kilomita 540 sama da Duniya a cikin ƙaramin zagayen Duniya, na'urar hangen nesa ta Hubble ta kasance tana aiki tsawon shekaru 35 da suka gabata. Binciken da ta yi a cikin zurfin fili ya nuna dubban taurarin da ba a san su ba a da. Hakanan ya ba da gudummawa wajen ƙididdige shekarun da suka dace da kuma saurin faɗaɗa sararin samaniya kuma ana ɗaukarta a matsayin babban ci gaba a cikin binciken sararin samaniya bisa ga sararin samaniya. 

Taswirar sararin samaniya ta James Webb (JWST) wani muhimmin suna ne. An ƙaddamar da ita a ranar 25 ga Disamba, 2021, JWST ita ce babbar na'urar hangen nesa mafi ƙarfi a sararin samaniya zuwa yanzu. Ba kamar Hubble wanda ke da na'urar hangen nesa a cikin sararin samaniyar ƙasa, JWST wani na'urar hangen nesa ce ta infrared da ke a wurin Lagrange na biyu (L2), kimanin kilomita miliyan 1.5 daga Duniya. An keɓe ta don nazarin sararin samaniya na farko, JWST an tsara ta ne don duba baya sama da shekaru biliyan 13.5 don lura da taurarin farko da aka kafa bayan Big Bang. A cikin shekaru biyar na ƙarshe na aiki, JWST ta kawo sauyi a fannin ilmin taurari, musamman nazarin sararin samaniya na farko.

Nancy Grace Roman Space Telescope

An shirya ƙaddamar da na'urar hangen nesa ta sararin samaniya ta Nancy Grace Roman, ko kuma kawai ta Roman Telescope, an sanya mata suna bayan Nancy Grace Roman, wacce ita ce babbar mai nazarin taurari ta farko a NASA da aka yaba da ita wajen jagorantar aikin Hubble Space Telescope. Ba kamar Hubble wanda ke cikin ƙasan sararin samaniyar Duniya ba, za a sanya Roman a cikin kuma yana aiki daga wani zagaye mai kama da halo a kusa da wurin Lagrange na biyu na Rana-Duniya (L2) a maƙwabtan JWST a nisan kilomita miliyan 1.5 daga Duniya.  

Na'urar hangen nesa ta Romawa za ta kai tsawon mita 12.7 da faɗin mita 4.4 idan aka yi amfani da ita gaba ɗaya. Za a iya kwatanta ƙudurinta da ƙarfinta da Hubble's saboda girmanta iri ɗaya (watau, diamita mita 2.4). 

Duk da haka, Roman zai sami filin gani sau 100 fiye da kyamarar sa mai girman megapixel 300 mai kusa da infrared mai suna Wide Field Instrument (WFI), wacce za ta samar da faifan hoton fili da kuma spectroscopy mai faɗi. Faifan kallon fili mai girman hoto da saurin bincike mai sauri zai ba wa Roman Telescope damar yin manyan bincike na taurari sama da biliyan ɗaya da tarin taurari masu taswirar rarrabawa da juyin halittar abu da kuma auna tarihin faɗaɗa duniya. Wannan zai ba da ra'ayi game da tasirin duhu da kuzarin duhu akan siffofi da rarraba taurari da tarin taurari a cikin sararin samaniya. 

Na'urar hangen nesa ta Roman za ta kuma lura da wani abu mai kama da na'urar hangen nesa ta Type Ia supernovae, wanda ke aiki a matsayin alamun faɗaɗawar sararin samaniya don siffanta makamashin duhu. A bayyane yake cewa, Na'urar hangen nesa ta Wide Field Instrument (WFI) za ta taka muhimmiyar rawa a cikin nazarin abubuwa masu duhu da makamashin duhu ta hanyar Na'urar hangen nesa ta Roman. Saboda babban rawar da Na'urar hangen nesa ta Wide Field Infrared ...  

Roman zai bincika kuma ya yi nazarin sararin samaniya. Zai yi amfani da microlensing, hoton kai tsaye, da transit don wannan. Ana sa ran lura da Roman zai bayyana sama da taurari 100,000 yayin da suke wucewa ta taurarin masu masaukin baki. Kayan aikin Coronagraph da ke cikin na'urar hangen nesa ta Roman zai toshe hasken taurari mai ƙarfi kuma ya ɗauki hotunan taurarin da tarkace a kewaye da su. 

Ta haka ne Roman zai ba da gudummawa ga nazarin abubuwan duhu, makamashin duhu, da kuma duniyoyin waje. 

Na'urar hangen nesa ta Roman da na'urar hangen nesa ta James Webb 

Na'urorin hangen nesa na sararin samaniya na Nancy Roman da James Webb za su yi aiki a lokaci guda. Dukansu za su yi nazarin sararin samaniya a cikin hasken infrared, duk da haka, sun bambanta a cikin ikon ɗaukar hoto amma suna iya haɗa juna a cikin nazarin abubuwan da suka faru na ilmin taurari. 

Duk da cewa Wide Field Instrument (WFI) yana bawa Roman damar ɗaukar manyan hotuna (fiye da girman Webb sau 50) da kuma samar da babban hoto, James Webb Telescope yana yin manyan abubuwan lura da ke gani a baya tare da ƙuduri mafi girma. Wannan saboda madubin Webb na farko ya fi girma (mita 6.5) idan aka kwatanta da na Roman (mita 2.4). 

Babban ra'ayin Roman da kuma manyan abubuwan da Webb ya lura tare za su iya taimakawa sosai a nazarin ilmin taurari. 

Na'urar hangen nesa ta Roman za ta yi aiki na tsawon shekaru biyar, sannan kuma ta yi aiki na tsawon shekaru biyar.
