Amathuluzi amasha kanye nokubhekwa okusha kwezinto zasemkhathini ezatholwa kudala kusivumela ukuthi sibone isithombe esicacile seNdawo Yonke esizungezile. Ngakho, eminyakeni emithathu edlule, i-spectrograph yegobolondo yaqala ukusebenza ngokunemba okumangalisayo kuze kube manje inqwaba ye-exoplanet eseduze kakhulu kithi ohlelweni lwe-Proxima Centauri. Ukunemba kwesilinganiso kwakungu-1/10 wesisindo soMhlaba, okungenzeka muva nje kubhekwe njengenganekwane yesayensi.
Ukuba khona kwe-exoplanet Proxima b kwamenyezelwa okokuqala ngo-2013. Ngo-2016, i-European Southern Observatory's (ESO) HARPS spectrograph yasiza ukunquma isisindo esilinganiselwe se-exoplanet, okwakungu-1,3 woMhlaba. Ukuhlolwa kabusha kwakamuva kwenkanyezi ebomvu ebomvu u-Proxima Centauri kusetshenziswa i-spectrograph yegobolondo le-ESPRESSO kubonise ukuthi isisindo se-Proxima b siseduze nesoMhlaba futhi singu-1,17 wesisindo seplanethi yethu.
Inkanyezi encane ebomvu u-Proxima Centauri itholakala eminyakeni engu-4,2 yokukhanya kusukela kusistimu yethu. Lokhu kuyinto elula kakhulu yokufunda, futhi kuhle kakhulu ukuthi i-exoplanet Proxima b, ezungeza le nkanyezi isikhathi esiyizinsuku eziyi-11,2, yaphenduka cishe iwele loMhlaba ngokwezimpawu zesisindo nosayizi. Lokhu kuvula ithuba lokucwaninga okwengeziwe nge-exoplanet, okuzoqhubeka ngosizo lwezinsimbi ezintsha.
Ikakhulukazi, i-European Southern Observatory eChile izothola i-High Resolution Echelle Spectrometer (HIRES) kanye ne-RISTRETTO spectrometer. Izinsimbi ezintsha zizokwenza kube nokwenzeka ukuqopha i-spectra ekhishwe yi-exoplanet ngokwayo. Lokhu kuzokwenza kube nokwenzeka ukufunda ngobukhona futhi, ngokunokwenzeka, ukwakheka komkhathi wayo. Iplanethi itholakala endaweni ebizwa ngokuthi indawo yokuhlala yenkanyezi yayo, okusivumela ukuba sibe nethemba lokuba khona kwamanzi awuketshezi endaweni yawo futhi, ngokunokwenzeka, nokuba khona kwempilo yebhayoloji.
Ngesikhathi esifanayo, kufanele kukhunjulwe ukuthi i-Proxima b iseduze izikhathi ezingu-20 kunkanyezi yayo kunokuba uMhlaba usondele eLangeni. Lokhu kusho ukuthi i-exoplanet ivezwe emisebeni ephindwe izikhathi ezingama-400 kunoMhlaba. Umkhathi ominyene kuphela ongavikela impilo yebhayoloji ebusweni be-exoplanet. Ososayensi banethemba lokuthola wonke lawa manuances ezifundweni ezizayo.
