Gulu lapadziko lonse la akatswiri odziwa zakuthambo komanso akatswiri a zakuthambo apeza dziko lomwe thambo lake limaunikira ndi dzuwa linai - chochitika choyamba chodziwika cha zochitika zoterezi.
Dzikoli, lomwe lili pafupifupi zaka 5,000 za kuwala kuchokera ku Dziko Lapansi, latchedwa PH1 polemekeza Planet Hunters, pulogalamu yotsogoleredwa ndi Yale University ku United States, yomwe imapempha anthu odzipereka kuti ayang'ane zizindikiro za mapulaneti atsopano.
PH1 imayenda madzuwa awiri, ndipo imazunguliranso ndi nyenyezi ziwiri zakutali. Ofufuza amati mapulaneti 6 okha ndi amene amadziwika kuti amazungulira nyenyezi ziwiri, ndipo palibe ngakhale limodzi mwa mapulaneti amenewa amene amazunguliridwa ndi nyenyezi zina zakutali.
"Mapulaneti ozungulira ndizomwe zimapangidwira kwambiri," atero a Meg Schwamb, wolemba wamkulu wa pepala loperekedwa Lolemba pamsonkhano wapachaka wa Division for Planetary Sciences of the American Astronomical Society ku Nevada.
"Kupezeka kwa machitidwewa kukutikakamiza kuti tibwererenso ku gulu lojambulira kuti timvetsetse momwe mapulaneti otere angasonkhanitsire ndikusinthika m'malo ovutawa." Asayansi nzika zaku US ndi ochita nawo Planet Hunters Kian Jek ndi Robert Gagliano anali oyamba kuzindikira PH1. Zomwe adawonazo zidatsimikiziridwa ndi gulu la ofufuza aku US ndi Britain omwe amagwira ntchito ku Hawaii.
PH1 ndi chimphona cha gasi chokhala ndi utali wozungulira pafupifupi nthawi 6.2 kuposa Earth, ndikupangitsa kuti ikhale yayikulupo pang'ono kuposa Neptune. Imazungulira nyenyezi ziwiri zomwe zimadutsa 1.5 ndi 0.41 kuchulukitsa kwa Dzuwa pafupifupi masiku 138 aliwonse.
Nyenyezi zina ziwirizi zikuzungulira mapulaneti pa mtunda womwe ndi pafupifupi nthawi 1,000 mtunda wapakati pa Dziko ndi Dzuwa.
Webusaiti ya Planethunters.org idapangidwa mchaka cha 2010 kuti ilimbikitse akatswiri a zakuthambo kuti azindikire mapulaneti omwe ali kunja kwa dzuŵa lathu, pogwiritsa ntchito deta yochokera ku bungwe la zakuthambo la US NASA's Kepler space telescope.
Kepler, yomwe idakhazikitsidwa mu Marichi 2009, ndi ntchito yoyamba ya NASA kufunafuna mapulaneti onga Earth ozungulira nyenyezi ngati Dzuwa lathu.
Kupezeka kwa PH1 kudapezeka pa intaneti Lolemba patsamba la arxiv.org ndipo kwatumizidwa ku Astrophysical Journal kuti ifalitsidwe.
"Zikupitilirabe kundidabwitsa momwe tingadziwire, osasiya kutolera zambiri, za pulaneti lina lomwe lili kutali ndi zaka masauzande a kuwala kokha mwa kuphunzira kuwala kochokera kwa kholo lake," adatero Jek.
Mlungu watha asayansi ananena kuti anapeza “planeti la diamondi” kuwirikiza kawiri kukula kwa dziko lapansi ndi kuzungulira nyenyezi yonga dzuwa.
Kufikira gawo limodzi mwa magawo atatu a unyinji wa dziko lapansi ndi mbali yake yayikulu imakhulupirira kuti ili ndi diamondi, kutanthauza kuti mapulaneti amiyala akutali sangathenso kuganiziridwa kuti ali ndi mawonekedwe ofanana ndi Dziko lapansi.
