Iqela leenkwenkwezi ezivela kwiprojekthi yesayensi efuna ubomi obungaphandle komhlaba, apho uStephen Hawking ongasekhoyo ebeyinxalenye, ufumanise ukuba bobuphi obona bungqina bunokubakho kude kube ngoku ngophawu lwangaphandle oluvela ngaphandle.
Ngokukodwa, abaphandi bafumene "umqondiso wonomathotholo othakazelisayo" ovela kwiProxima Centauri, inkqubo esondeleyo yelanga, nje iminyaka eyi-4.2 yokukhanya ukusuka eLangeni.
Umqondiso
Umqondiso omangalisayo kanomathotholo ovela koyena mmelwane wethu usondeleyo, uProxima Centauri, "uphandwa ngononophelo" liqela leenkwenkwezi kwiiprojekthi Ukuqhekeka Mamela.
Umqondiso, ovele ngokutshintsha nje okuncinci kwibhanti emxinwa yee-frequency ze-980 megahertz-ehambelana nommandla werediyo oqhele ukungabikho kuthumelo olusuka kwiisathelayithi kunye nezinto ezenziwa ngabantu okanye iziphekepheke-zabantu iteleskopu ngo-Epreli nango-Meyi 2019, ngokwengxelo epapashwe yi-Guardian.
Umqondiso, ngokutsho kwezazinzulu, uvela kwicala lenkwenkwezi iProxima Centauri, engummelwane wethu osondeleyo welanga emajukujukwini.
Okulandelayo b
I-Centauri B ibonakaliswe njengendawo eyomileyo (kodwa engenamanzi ngokupheleleyo) enamatye e-Super-Earth. Oku kubonakala yenye yeziphumo ezininzi ezinokubakho zeethiyori zangoku ngokubhekisele kuphuhliso lwe-exoplanet, ngelixa imbonakalo yokwenyani kunye nokwakheka kweplanethi kwaziwa ngandlela zimbi okwangoku. Iproxima Centauri b yeyona exoplanet ikufutshane kwiLanga kunye neyona ndawo ikufutshane enokuhlala abantu nayo. Ijikeleza iProxima Centauri, into ebomvu ebomvu enobushushu bomhlaba obungama-3040 K (ishushu ke kuneebhalbhu zokukhanya kwaye ngenxa yoko zimhlophe, njengoko kubonisiwe apha).

IProxima Centauri yiminyaka eli-4.2 ekhanyayo ukusuka eMhlabeni (phantse ama-40 ezigidi zeekhilomitha) kwaye ineeplanethi ezimbini eziqinisekisiweyo, isigebenga esifana neJupiter kunye nehlabathi elinamatye elifana noMhlaba elibizwa ngokuba yiProxima B “kwindawo ekuhlalwa kuyo”. Ulwelo olunamanzi lwalunokuhamba phezu komhlaba.
Nangona kunjalo, kuba iProxima Centauri yinto ebomvu ebomvu, indawo ekuhlalwa kuyo isondele kakhulu kwinkwenkwezi. Oku kuthetha ukuba iplanethi inokuba itshixiwe ngamaza kwaye ibonakaliswe kwimitha ebukhali, eyenza ukuba kungalindelekanga ukuba nayiphi na impucuko ibinokubakho, ubuncinci ngaphezulu.
Iplanethi yesithathu ngaphakathi kwenkqubo?
Umqondiso, ongakhange ubangelwe nakweyiphi na imithombo yomhlaba okanye eyenziwe ngabantu kufutshane noMhlaba, kunokwenzeka ukuba inenkcazo yendalo nangona kunjalo. Nangona kunjalo, izazi ngeenkwenkwezi zabaphambukeli ziye zamangaliswa ngumqondiso omangalisayo.
Yiyo ke loo nto, umqondiso kanomathotholo obhaqwe kuluhlu lwama-980 megahertz, ukongeza kutshintsho lobuninzi obufunyenwe yiteleskopu yePark, iyahambelana nokuhamba kweplanethi. Oku kuphakamisa ukuba ingangubungqina besijikelezi-langa sesithathu kwinkqubo, endaweni yeempawu zempucuko engaqhelekanga, into abaphandi abathi "ayinakulindeleka."
UPete Worden, umlawuli wamanyathelo okuqhekeka, uxelele i-Guardian ukuba imiqondiso kungenzeka ukuba iphazamisekile kwimithombo yomhlaba esingakwaziyo ukuyichaza. Nangona kunjalo, wathi kubalulekile ukulinda kwaye ubone ukuba yeyiphi na iprojekthi oosonzululwazi abagqibayo ngokujonga ngocoselelo umqondiso.
Wow!
Iqela lithi le yenye yezona zinto zinomdla kwirediyo ukusukela oko Wow! nto leyo eyakhokelela ekubeni abaninzi bacinge ukuba isuka kwimpucuko ekude yabangaphandle.
Wow! yayiyeyexesha elifutshane, irediyo ebhendi emxinwa yathathwa ngexesha lokukhangelwa kwenkqubo yezobukrelekrele (Seti), yi-Big Ear Radio Observatory e-Ohio ngo-1977.
Umqondiso ongaqhelekanga, owawuthiywa ngegama lesazi ngeenkwenkwezi uJerry Ehman wabhala wathi “Wow!” Kunye nedatha, kuye kwabangela ukonwaba okukhulu, nangona u-Ehman walumkisa ngokufumana "izigqibo ezininzi ukusuka kubude obuphakathi."
