Iqela lamazwe ngamazwe lezazi ngeenkwenkwezi ezisafundayo kunye neengcali zeenkwenkwezi ziye zafumanisa iplanethi enesibhakabhaka esikhanyiswe ngamalanga amane - isiganeko sokuqala esaziwayo sento enjalo.
Iplanethi, ibekwe malunga ne-5,000 yeminyaka yokukhanya ukusuka eMhlabeni, iye yabizwa ngokuba yi-PH1 ngokuhlonipha i-Planet Hunters, inkqubo ekhokelwa yiYunivesithi yaseYale e-United States, efaka amavolontiya ukuba akhangele iimpawu zeeplanethi ezintsha.
I-PH1 ijikeleza ilanga ezimbini, kwaye ijikeleziswa ziinkwenkwezi ezimgama zesibini. Zintandathu kuphela iiplanethi ezaziwa ngokujikeleza iinkwenkwezi ezimbini, abaphandi bathi, akukho nanye kwezo ejikeleziswa zezinye iinkwenkwezi ezikude.
"Iiplanethi ezijikelezayo zizinto ezigqithiseleyo zokubunjwa kweplanethi," watsho u-Yale's Meg Schwamb, umbhali okhokelayo wephepha elinikezelwe ngoMvulo kwintlanganiso yonyaka yeCandelo leSayensi yePlanethi ye-American Astronomical Society e-Nevada.
"Ukufunyanwa kwezi nkqubo kusinyanzela ukuba sibuyele kwibhodi yokuzoba ukuze siqonde ukuba iiplanethi ezinjalo zinokuhlangana njani kwaye zivele kwezi meko zinzima." Izazinzulu zabemi base-US kunye nePlanethi Hunters abathathi-nxaxheba u-Kian Jek noRobert Gagliano babe ngabokuqala ukuchonga i-PH1. Uqwalaselo lwabo lwaqinisekiswa liqela labaphandi base-US nabaseBrithani abasebenza eHawaii.
I-PH1 sisigebenga serhasi esineradiyasi malunga ne-6.2 umphinda-phinde ngowoMhlaba, iwenza ube mkhulu kancinci kuneNeptune. Ijikeleza ipere yeenkwenkwezi ezisithwa yi-1.5 kunye ne-0.41 ukuphinda-phinda ubunzima beLanga malunga neentsuku ezili-138.
Ezinye iinkwenkwezi ezimbini zijikeleza inkqubo yeplanethi kumgama omalunga ne-1,000 umgama ophakathi koMhlaba neLanga.
Iwebhusayithi yePlanethunters.org yadalwa ngo-2010 ukukhuthaza izazi ngeenkwenkwezi ezisafundayo ukuba zichonge iiplanethi ezingaphandle kwesixokelelwano sethu selanga, kusetyenziswa idatha evela kwi-arhente yase-US ye-NASA's Kepler spacetelescope.
I-Kepler, eyasungulwa ngoMatshi ka-2009, yimishini yokuqala ye-NASA yokukhangela iiplanethi ezinjengoMhlaba ezijikeleza iinkwenkwezi ezifana neLanga lethu.
Ukufunyanwa kwe-PH1 yenziwe yafumaneka kwi-intanethi ngoMvulo kwindawo arxiv.org kwaye ithunyelwe kwi-Astrophysical Journal ukuze ipapashwe.
“Isandimangalisa indlela esinokubhaqa ngayo, singasathethi ke ngokuqokelela ulwazi oluninzi, malunga nesinye isijikelezi-langa esikumawakawaka eminyaka yokukhanya ngokufunda nje ukukhanya okuvela kumzali wayo,” utshilo uJek.
Kwiveki ephelileyo izazinzulu ziye zabika ngokufunyanwa “kweplanethi yedayimani” ephindwe kabini kubukhulu bomhlaba kunye nokujikeleza inkwenkwezi efana nelanga.
Ukuya kuthi ga kwisinye esithathwini sobunzima beplanethi kunye nobuninzi bomhlaba kukholelwa ukuba bunedayimane, nto leyo ethetha ukuba iiplanethi ezikude ezinamatye azinakuphinda kucingelwe ukuba zineempawu ezifanayo noMhlaba.
