Iqembu lezazi zezinkanyezi ezivela kuphrojekthi yesayense ebheka impilo engaphandle komhlaba, okwakuyingxenye yalo ongasekho uStephen Hawking, lisanda kuthola ukuthi kungaba yini ubufakazi obedlula bonke kuze kube manje ngesiginali esivela kwamanye amazwe.
Ngokuqondile, abacwaningi bathole "isignali yomsakazo ethakazelisayo" evela ku-Proxima Centauri, isistimu esondelene kakhulu yelanga, nje iminyaka engu-4.2 yokukhanya kude ne-Sun.
Isiginali
Isignali yomsakazo engaqondakali evela kumakhelwane wethu osondelene kakhulu, uProxima Centauri, "iphenywa ngokucophelela" yithimba lezazi zezinkanyezi ezivela kuphrojekthi Ukuqhekeka Lalela.
Isiginali, ebivele ngokushintshashintsha okuncane kuphela ebhendini elincane lamafrikhthi angama-980 megahertz - ahambelana nesifunda somsakazo esivame ukungabi nokuhanjiswa okuvela kumasathelayithi nakumkhumbi-mkhathi wokufakelwa noma womuntu - besivele sitholwe ngumsakazo we-Australia Parkes isibonakude ngo-Ephreli nangoMeyi 2019, ngokusho kombiko oshicilelwe yiThe Guardian.
Isiginali, ngokusho kososayensi, yaqhamuka ngakuyo inkanyezi iProxima Centauri, okungumakhelwane wethu osondele kakhulu welanga emkhathini.
Okulandelayo b
I-Centauri B ikhonjiswe njenge-Super-Earth eyomile (kodwa hhayi engenamanzi ngokuphelele). Lokhu kubonakala kungenye yemiphumela eminingana yemibono ekhona maqondana nokwakhiwa kwale exoplanet, kuyilapho ukubukeka nokwakheka kweplanethi kungaziwa ngalutho ngalesi sikhathi. I-Proxima Centauri b iyisizinda esiseduze kakhulu seLanga futhi iyisizinda esiseduze kakhulu esingahlalwa futhi. Izungeza iProxima Centauri, into encane ebomvu enezinga lokushisa elingaphezulu kuka-3040 K (ngaleyo ndlela ishisa kakhulu kunama-light light ngakho-ke imhlophe, njengoba kuboniswe lapha).

I-Proxima Centauri ingama-light-years ayi-4.2 ukusuka eMhlabeni (cishe amakhilomitha angama-40 trillion) futhi inamaplanethi amabili aqinisekisiwe, igesi enkulu efana neJupiter kanye nomhlaba onamadwala obizwa ngeProxima B “endaweni ehlala abantu”, okuyindawo lapho amanzi angamanzi angageleza ebusweni beplanethi.
Kodwa-ke, njengoba iProxima Centauri ingumbala obomvu, indawo okuhlala kuyo isondele kakhulu enkanyezini. Lokhu kusho ukuthi iplanethi kungenzeka ikhiyelwe amagagasi futhi ivezwe yimisebe enamandla, okwenza kungabi namathuba ukuthi noma iyiphi impucuko ibingakheka, okungenani ngaphezulu.
Iplanethi yesithathu ngaphakathi kohlelo?
Isiginali, engabaliwe kunoma imuphi umhlaba noma imithombo eyenziwe ngabantu esondelene noMhlaba, kungenzeka ukuthi ibe nencazelo yemvelo noma kunjalo. Noma kunjalo, izazi zezinkanyezi zabazingeli bezinye izizwe ziye zamangazwa yisiginali engaqondakali.
Ngakho-ke, isignali yomsakazo etholwe ebangeni le-megahertz engu-980, ngaphezu kwezinguquko kumvamisa otholwe yisibonakude iParkes, iyahambisana nokuhamba kweplanethi. Lokhu kusikisela ukuthi kungaba wubufakazi beplanethi yesithathu ngaphakathi kohlelo, kunokuba kube yizimpawu zempucuko engaziwa, into abacwaningi abathi "ayinakwenzeka kakhulu."
UPete Worden, umqondisi weBreakthrough Initiatives, utshele iThe Guardian ukuthi lezi zimpawu kungenzeka ziphazamiseke emithonjeni yomhlaba esingakwazi ukuyichaza okwamanje. Kodwa-ke, uthe kubalulekile ukulinda ubone ukuthi ososayensi bephrojekthi baphetha ngokuhlolisisa lesi siginali.
Wow!
Leli thimba lithi lesi ngesinye sezimpawu zomsakazo ezijabulisa kakhulu kusukela lapho Wow! okwaholela abaningi ekucabangeni ukuthi kwavela empucukweni ekude yabokufika.
Wow! kwakuyisiginali yomsakazo ehlala isikhathi esifushane, nebhendi elincane eyathathwa ngesikhathi kuseshwa uhlelo lwangaphandle lwezobunhloli (i-Seti), yi-Big Ear Radio Observatory e-Ohio ngo-1977.
Isiginali engajwayelekile, eyaqanjwa ngegama lesazi sezinkanyezi uJerry Ehman ibhale ukuthi “Hawu!” Ngokuhambisana nedatha leyo, kwavusa isasasa elikhulu, yize u-Ehman axwayisa ngokuthola "iziphetho ezinkulu ngemininingwane yobude obuphakathi."
