Ukukhangela ubomi esithubeni ndithathe nje umtsi omkhulu ukuya phambili. Abaphandi abasebenza kuMhlaba oMtsha kwiProjekthi yeAlfa Centauri yeNgingqi (kufutshane), exhaswa ngemali ngusomashishini uYuri Milner kunye ne-apos; s Amanyathelo okuqhekeza, banokufumana iplanethi entsha kwindawo ekuhlalwa kuyo yenkwenkwezi ekufutshane neAlpha Centauri A, ebekwe kwiminyaka engama-4.37 yokukhanya ukusuka eMhlabeni. Ingxelo yabo yapapashwa kwi Unxibelelwano lweNdalo kule veki.
Kumfanekiso othathwe yinkwenkwezi nge-European Southern Observatory & apos; s (ESO) iTeleskopu enkulu kakhulu (VLT) eChile, iqela labona into eyahlukileyo eqaqambileyo. Bakrokrela ukuba isenokuba yiplanethi-leyo iphindaphindwe kane ukuya kwezihlanu ubukhulu kunoMhlaba, okanye ubukhulu beNeptune. I-apos ibekwe phakathi kweyunithi enye ukuya kwezimbini ze-astronomical (AU) ukusuka kwinkwenkwezi yayo (enye ye-AU ngumgama osuka eMhlabeni uye elangeni), ukubeka iplanethi kwindawo ekuhlalwa kuyo, apho amanzi anokukwazi ukwenza ukwenza ukuxhasa ubomi.
Eyona nto ibangela umdla kwizazinzulu kukuba iAlpha Centauri A yinkwenkwezi ebambekayo eneAlpha Centauri B - uninzi lwethiyori yokuba iiplanethi azinako ukwenza inkqubo enjalo yokubini. Nangona kunjalo, iplanethi kuphela ngumgqatswa weplanethi okwangoku, njengoko iqela lophando lifuna idatha ethe kratya ukuqinisekisa ubukho bayo.
'Simangalisiwe kukufumana umqondiso kwidatha yethu,' isifundo kunye nommeli-mbhali u-Kevin Wagner kwingxelo. Ngelixa ubhaqo luhlangabezana nazo zonke iindlela zokuba umhlaba ungabonakala njani, ezinye iinkcazo-ezinje ngothuli olujikeleza kwindawo ekuhlalwa kuyo okanye isixhobo nje semvelaphi esingaziwayo- kufuneka sisiwe ngaphandle.
Ukuba iya kuba yiplanethi, ngekhe kumangalise. Ngo-2016, oososayensi bafumanisa iplanethi enokuhlala kuyo ejikeleza inkwenkwezi yesithathu kwinkqubo yeAlpha Centauri, Proxima Centauri . (Le nkwenkwezi yenze nemixholo kunyaka ophelileyo xa izazi ngeenkwenkwezi zafumanisa ukuba uphawu lwerediyo engaqhelekanga ivela kwingingqi yayo.)

Into enomdla kukuba elona candelo linomdla loku kufumanisa ayisiyiyo umgqatswa weplanethi uqobo-ziiipos Njani izazinzulu ziyibonile. Ngaphambili, izazi ngeenkwenkwezi zazinokumisela kuphela ubukho be-exoplanets ngokubukela indlela yokuziphatha kweenkwenkwezi. Ukuba ziyadima ngexesha lokujonga, iiplanethi zinokudlula phambi kwazo; ukuba ziyaxengaxenga, kusenokwenzeka ngenxa yeplanethi ekufutshane kunye neapos;
Iqela elikufutshane kunye nokuqwalaselwa okutsha, nangona kunjalo, kuphawula okokuqala ukuba izazinzulu zikwazile ukwenza umfanekiso ngqo (Oko kukuthi, ngokuyintloko ifoto) indawo ekuhlalwa kuyo yenkwenkwezi ekufutshane, ivula ilizwe elitsha elinokubakho xa kusiza ekufuneni exoplanets.
'Nokuba le nto iyinyani yile, kum, phantse isekondari,' u-coauthor u-Olivier Guyon uxelelwe Inzululwazi yaseMelika . Kungenxa yokuba nokuba yeyiphi na indlela ebonisa ukuba sivula ngokucacileyo ixesha elitsha kwimbali ye-astronomy apho, ekugqibeleni, emva kweminyaka engaphezulu kwama-20 yokusebenza nzima, ekugqibeleni sinokwenza umfanekiso-ngqondweni wenye inkwenkwezi kunye neendawo zokuhlala. Le yi & apos; umdlalo kwi & apos; umzuzwana webala. '
Ke, nokuba lo mgqatswa weplanethi ujika abe sisuntswana lothuli okanye i-glitch yoomatshini, kusekho izinto ezininzi ezinokonwaba malunga-nokuba ubunesazi ngeenkwenkwezi.
