Soo koob maqaalka:  Labo dhibcood oo ifaya oo qarsoon oo ku yaalla asteroid Ceres ayaa noqon kara 'bulkaano biyo' ah, saynisyahannadu waxay sheegeen. Sawirro dhowaan laga soo qaaday dayax-gacmeedka Dawn ayaa muujinaya dhibcaha, oo loo yaqaano 'feature number 5', oo leh xaglo kala duwan marka uu asteroidku wareegayo. Iftiiminta iftiinka ayaa la arki karaa xitaa marka ay ku dhow yihiin cidhifka Ceres, taasoo soo jeedinaysa in ay tahay inay ka sarreeyaan dusha sare halkii ay ka ahaan lahaayeen hoose ee godka, sida horay loo rumeeyay. Hoos u rog fiidiyowga. Ceres waxay ku wareegeysaa fiidiyowgaan xawaaraha sare leh kaas oo ka kooban sawiro ay qaaday howlgalka NASA ee Dawn inta uu ku soo dhowaanayay meeraha dwarf. Iftiiminta iftiinka ayaa la arki karaa xitaa marka ay u dhow yihiin cidhifka Ceres, taasoo soo jeedinaysa in ay ku jiraan meel sare marka loo eego dusha sare ee dusha sare. 'Waxa la yaab leh waa in aad arki karto muuqaalka halka geeska uu weli ku jiro line of sight,' ayuu yiri Andreas Nathues, oo ah saynisyahan ku takhasusay cilmiga meerayaasha oo ka tirsan Max Planck Institute for Solar System Research ee Göttingen, Germany. Wuxuu xusay in marka waagu beryo ay calaamadahaasi aad u iftiimaan, laakiin ay yaraadaan marka ay mugdigu sii dhowaado. Sida laga soo xigtay Nature, tani waxay micnaheedu noqon kartaa in iftiinka qoraxdu uu door muhiim ah ka ciyaarayo sameynta qaababka, tusaale ahaan, kuleylinta barafka ee ka hooseeya dusha sare iyo sababo u noqoshada dusha sare. Seynisyahanada waxay ku andacoodeen in gudaha Ceres uu yahay dhagaxyo leh lakab biyo iyo baraf ah. Aragtida ugu horreysa ee hada la xiriirta dhibcaha shisheeyaha ayaa ah in barafka uu daboolay lakab khafiif ah oo ciid ah oo mararka qaar sameysma 'cryovolcanoes' oo waa weyn sababtoo ah cadaadiska gudaha ee asteroid. Ceres waxay sii wadaa inay jahwareerto aqoonyahanada cilmiga xiddigiska maadaama Dawn ay ku wareegeyso meeraha dwarf. Sawirkan waxaa qaaday dayax-gacmeedka Dawn oo laga leeyahay meeraha yar ee Ceres bishii Febraayo 19-keedii meel u jirta ku dhawaad 29,000 miles (46,000 km). Waxay muujineysaa in meesha ugu iftiinka badan Ceres ay leedahay mid ka mugdi badan, taas oo sida muuqata ku taal isla saxanka. Dawn waxay aragtay Ceres oo dhameystiraya hal wareeg oo buuxa, kaas oo qaatay qiyaastii sagaal saacadood. Sawiradani waxey muujinayaan dhamaan noocyada kala duwan ee qaababka burburka ee laga heli karo dusha sare ee Ceres: laga soo bilaabo qoto dheer, burburka fidsan ilaa...
Sawirada laga soo qaaday Dawn waxay muujinayaan dhibcaha, oo loo yaqaano 'feature number 5', oo ah xaglo kala duwan marka uu asteroidku wareegayo. Goobahaas waxaa la arki karaa marka ay ku dhow yihiin geesaha Ceres, taasoo muujineysa in ay ka sarreeyaan dusha sare. Aragtida ugu weyn ayaa ah in barafku uu daboolan yahay lakab khafiif ah oo ciid ah oo qarxi kara cadaadiska ku jira asteroid.
