Ubukho be-super-Earth obunokubakho bujikeleze inkwenkwezi ekufutshane nelanga lethu, ngokophando olutsha olupapashwe kule veki.
I-super-Earth enokwenzeka, iProxima c, yafunyanwa ijikeleza inkwenkwezi yeProxima Centauri, kuphela yiminyaka eyi-4.2 yokukhanya ukusuka kwiplanethi yethu kunye neyona ikufutshane. inkwenkwezi elangeni lethu, CNN ixelwe .
Kukufunyanwa kwesibini kweplanethi ejikeleza loo nkwenkwezi- uthungelwano luxele ukuba izazi ngeenkwenkwezi ngo-2016 zafumana iplanethi iProxima b, abathi yayinokuhlala.
Amagcisa acinga ngenkqubo yePlanethi yeProximas Ukunikezelwa kwegcisa kwePromixa Centauri. Iproxima yeyona nkwenkwezi ikufutshane kwiLanga. Ububomvu obumnyama, buncinci kuneLanga lethu kwaye amaxesha amaninzi aphelile. Apha siyibona ibonwa kunye nomhlaba onamatye ojikelezayo, osandula ukufunyanwa. | Ityala: MARK GARLICK / ISAYENSI IFOTO LIBRA / Getty Izithombe){kind=link}
Uphononongo, olupapashwe kwiphephancwadi Ukuqhubela phambili kwezeNzululwazi , yajonga ngaphezulu kweminyaka eli-17 yedatha yesantya esivela kwinkqubo yeenkwenkwezi emva kokuba befumene umqondiso phaya, ngokwe CNN . Inkwenkwezi yeProxima Centauri ikwanenkwenkwezi yokubini kwiAlpha Centauri kwikroza leCentaurus, kwaye ayinakubonwa ngeliso lenyama.
Ukuba iplanethi entsha ngokwenene 'inguMhlaba oMkhulu,' kuya kuthetha ukuba yayiyi-exoplanet enobunzima obuphezulu kunoMhlaba wethu kodwa iphantsi kuneeplanethi ezinje ngeUranus neNeptune, Iindaba zeendaba ixelwe .
'Ngolu hlobo lwenkwenkwezi silindele ukuba iinkqubo zeeplanethi ezinobunzima ziqheleke,' utshilo uMario Damasso, we-INAF Astrophysical Observatory yaseTurin, uxelele Iindaba zeendaba . 'Emva kokufunyanwa kwesijikelezi-langa iProxima b, oogxa bethu balandela uProxima eqokelela iinkcukacha ezithe kratya zonyaka omnye, ngeenjongo zokufumanisa iiplanethi ezongezelelweyo.'
Izazi ngeenkwenkwezi kuqala zigqibe kwelokuba zikhangele kule planethi intsha emva kokubona ukukhanya kumthombo ongaziwayo ngexesha lophando lwangaphambili, ngokuka Iindaba zeendaba . Bakholelwa ukuba iplanethi entsha enokubakho ijikeleza inkwenkwezi yayo rhoqo kwiminyaka emi-5.2.
UDamasso walumkisa, nangona kunjalo, ukuba umsebenzi wamagnetic ojikeleze iProxima Centauri unokwazisa imiqondiso enokulinganisa ezo zeplanethi. Esi sesinye sezizathu zokuba silumke kwibango lethu. ' Uthe uphando olulandelayo luyimfuneko.
Ngokweli phephancwadi, iProxima b ithathwa njengeyona ndawo ithembisayo kwizazinzulu ezifuna iimpawu zobomi ngaphandle kweSolar System ngenxa yokusondela emhlabeni kunye nangenxa yokuba 'ikummandla onokuhlala' kuwo inkwenkwezi.
