Nyanzvi dzenyeredzi dzakatipa ruzivo rwakadzama nezveramangwana renyika kuburikidza nekuwana kwakajeka kubva mubhuku resainzi. Pachivanhu, taifunga kuti kana nyeredzi yafa, yaitora zvese zviri munzira yayo, kunyanya mapuraneti ari pedyo. Zvisinei, WD 1856+534 system yakaratidza kuti Dzimwe nyika dzakaoma varume uye kuti kufa kwezuva ravo hakufaniri kuva mugumo wenzira yavo.
Zvinoitika kuti iyo James Webb Telescope Yakaisa pfungwa dzayo papuraneti yakakura seJupiter inotenderera nyeredzi yakasara, nyeredzi chena, iri kure isingafungidzike. Dai takabheja mamiriyoni mashoma emakore apfuura, hapana angadai akapa kana sendi kuti nyika ino irarame, izvo zvaifanira kunge zvakatoitika. yakapiswa panguva yekuwedzera yenyeredzi yayo muchikamu chayo chikuru chitsvuku. Pasinei nezvinobvira, ichiripo, ichitipa ruzivo rwakakosha nezvezvichaitika kunharaunda yedu yepasi rose kana Zuva rapera.
Munhu akapona munzvimbo yakarambidzwa iri kure nemakore echiedza mamiriyoni makumi masere
Exoplanet iri kutaurwa nezvayo, inozivikanwa seWD 1856 b, iri kure nemakiromita angangoita mamiriyoni makumi masere nemaviri echiedza kubva kwatiri uye yave nzvimbo inonyanya kutariswa nesainzi. Nekuda kwezvishandiso zveWebb Space Telescope zvine hungwaru, zvakaita seNIRSpec, vaongorori venyeredzi vakakwanisa kuita kuverenga zvakananga kemesitiri yayo yemhepo nyika payaifamba pamberi penyeredzi yayo. Chavakawana yaive mhepo yakakora, ine makore uye kuvapo kwakajeka kwemethane, chimwe chinhu chinoyeuchidza zvishoma nezvekugadzirwa kweTitan, mwedzi wakakurumbira weSaturn.
Iyi hofori yegesi chinhu chinoshamisa mupuzzle yemuchadenga, sezvo ine huremu hunosvika kanomwe kupfuura hweJupiter asi inotenderera nyeredzi yakakura sePasi. Nekuti nyeredzi iyi idiki uye yakakora, pasi rinovhara chiedza chePasi chinopfuura chikamu chidiki. hafu yechiedza chenyeredzi Pakufamba kwayo, masayendisiti akakwanisa kuona chiratidzo chayo chespectral zvakajeka zvisati zvamboonekwa. Uyezve, pasi rakaonekwa richidziya kupfuura zvaitarisirwa kana tichitarisa nzvimbo yaro yazvino, zvichiratidza kuti rakagamuchira simba rakawanda munguva yaro isina kugadzikana.
Chirahwe chekutama uye chitambi cheSpanish
Mubvunzo mukuru uri kubvunzwa nevaongorori pasi rose, kusanganisira mapoka eYunivhesiti yeSt Andrews neYunivhesiti yeMichigan, ndewekuti nyika yakasvika sei ikoko. Dzidziso iri kuwana simba guru haisi yekuti yakapona mumoto weguruva guru, asi kuti yaive kufamba kwesimba rinokwevera pasi kunoteveraNemamwe mashoko, pasi redu ringangodaro raiva mudenderedzwa rakachengeteka uye riri kure, asi simba redzimwe nyeredzi muhurongwa hwacho rakarisundira mukati apo nyeredzi yakanga yatova dhoo rechena.
Kubva munyika yedu, vesainzi vari kuteverawo kufambira mberi uku. Eva Villaver, mutevedzeri wemukuru we Canary Islands Institute of AstrophysicsAkataura kuti mhando idzi dzezvakawanikwa dzakakosha pakuvakazve nhoroondo yakazara yekushanduka-shanduka kwezvinhu hurongwa hwemapuranetiHazvisi kungotarisa kumashure kuti tione zvakaitika, asi kekutanga, tiri kushandisa masisitimu aya senzira mhando yemuchina wenguva kufanoona ramangwana renguva refu reSolar System yedu, chimwe chinhu chaive dzidziso chaiyo kusvika pari zvino.
Iri ndiro ramangwana rakamirira Jupiter here?
Pavanoona WD 1856 b, nyanzvi dzenyeredzi hadzigoni kurega kufunga nezvenharaunda yedu. Mumakore angangoita mabhiriyoni mashanu, Zuva richapera mafuta uye richakura, zvichida richifukidza Pasi. Jupiter, sezvo iri kure, inofanira kuramba iripo padanho iroro rekutanga, asi zvinoitika mushure maizvozvo zvaive zvakavanzika. Kuwanikwa uku kunosimbisa kuti a Kambani huru yegesi inogona kuchengetedza mamiriro ayo ekunze kunyangwe mushure mekunge nyeredzi yayo yadonha, zvichivhura musuwo wekuti Jupiter itangewo "hupenyu hwechipiri" yakakomberedza zvasara zveZuva.
Rufu rwenyeredzi haruchaonekwi semugumo chaiwo wehurongwa hwemapuraneti, asi senzvimbo inosuruvarisa zvishoma. Chokwadi chekuti WD 1856 b inoramba ichitenderera pamwe chete ne zvikamu zvisina gasi Mushure memabhiriyoni emakore, zvinoratidza kuti muchadenga mune nzira dzekuchengetedza dzatiri kutanga kunzwisisa. James Webb Space Telescope ine mimwe mitambo yekutarisa yakarongerwa kunatsiridza huremu hwepasi chaihwo uye kuona kana nyaya iyi iri kunze kwemutemo kana kuti kana nzvimbo yakazara nenyika idzi dzakasimba dzakamirira kuwanikwa.
Kuwanikwa uku kwakakosha nekuti kunosimbisa kuti mapuraneti anogona kupona kuparadzwa kwenyeredzi dzawo uye, chinonyanya kukosha, kuti tinokwanisa kuverenga mhepo dzawo kuti tinzwisise kuti vakazviita sei. Kunyangwe Nyika iri munzvimbo ine njodzi mune ramangwana, tichiziva kuti zvinhu zvakaita seJupiter zvine mikana chaiyo yekupona Inopa maonero akapfuma kwazvo pamusoro pe kugara uye kuramba uchiita yemapuraneti nekufamba kwenguva.
