Pfupisa nyaya yacho:  Chiedza chiri mumifananidzo iyi inoshamisa chakafamba kure zvokuti chakatora makore 4.200 kuti chisvike pano. Asi, pasinei zvapo nokure, masayendisiti anoti mifananidzo yacho inoratidza, sezvisina kumboitika, masimba makuru anosunungurwa apo nyeredzi inoberekwa. Mifananidzo miviri yacho yakatorwa makore 18 akaparadzana, wokutanga wakatorwa neKarl G. Jansky Very Large Array muNew Mexico muna 1996 uye wechipiri neboka renyika dzakawanda ravazivi venyeredzi rinotungamirirwa neNational Autonomous University of Mexico (UNAM) gore rapera. Dzorera pasi kuti uone vhidhiyo. Vazivi venyeredzi vakashandisa teresikopu muNew Mexico kuti vatarire nyeredzi ichiumba mumakore masere. Kuenzanisa uku kunoratidza kuti kubuda kwezvinhu kubva munyeredzi kwave kuchiwedzera zvikuru sezvo kunenge kuchiumba. Mufananidzo wakaenzanisirwa wa1996 uri kuruboshwe, uye mumwewo wa2014 uri kurudyi. Nyeredzi yacho <unk> inozivikanwa seW75N(B) - VLA2 <unk> inopenya kakapetwa ka300 uye yakakura kakapetwa kasere kupfuura zuva redu, kunyange zvazvo yakafukidzwa negore dema reguruva romuchadenga. Asi chakanyanya kufadza vazivi venyeredzi kuchinja kwakaita chimiro chechiedza chepepuru chemhepo inopisa zvikuru ine magetsi iri kubudiswa nenyeredzi duku iyi. Kuchinja kunoshamisa uku, kunongoitika kamwe kamwe mudenga zvichienzaniswa nezera rechisiko chose, kuri kupa mufananidzo usingaenzaniswi wokukura kunoita "nyeredzi dzokutanga" kuti dzive nyeredzi dzakakura. Mifananidzo yacho, yakagadzirwa nemashoko anobva kumatepi eredhiyo 27 ari murenje reNew Mexico muU.S.A., inoratidza mhepo ine magetsi ichiwedzera kure nenyeredzi kutozosvikira yadzikiswa negore reguruva dema neritsvuku rinopoteredza. Mifananidzo iyi yenyeredzi yakatorwa neKarl G. Jansky Very Large Array muNew Mexico. Kuruboshwe kune nyeredzi yakaonekwa muna 1996, neguruva rayo rakaputirwa zvakasimba pariri, nepo pakazosvika muna 2014 mumufananidzo uri kurudyi, kubuda uku kwave kuchisundirwa kunze muchimiro chakatambanuka. Mufananidzo uyu unoratidza kukura kweW75N(B) -VLA-2. Kuruboshwe, mhepo inopisa inobva kunyeredzi duku inowedzera sechinhu chakatenderera, sezvinoonekwa muna 1996. Kurudyi, sezvinoonekwa muna 2014, mhepo inopisa yakaumbwa nokusangana neguruva, rakafanana nedonati...
Nyanzvi dzezvomuchadenga dzakashandisa teresikopu muNew Mexico kuti dzicherechedze kugadzirwa kwenyeredzi. Inonzi W75N(B) - VLA2 inopenya kakapetwa ka300 kupfuura zuva. Mifananidzo yakabva muna 1996 na2014 inoratidza kuti iri kutanga kuoneka sei. Inogona kupa nzwisiso isati yamboitwa mukuzvarwa kwenyeredzi huru.
