Ka taƙaita labarin:  Abubuwa biyu masu ban mamaki, masu haske a farfajiyar duniyar dwarf Ceres na iya samun asali daban-daban, bisa ga sabbin hotunan infrared da NASA ta fitar. Hotunan, wanda aka kama ta hanyar binciken Dawn daga nisan mil 28,000 (45,000km), ya nuna cewa wasu wurare masu ban mamaki a kan duniyar dwarf suna da halaye daban-daban. An bayyana hotunan a matsayin wani ɓangare na taswirar launi na farko na Ceres, yana nuna bambance-bambance a cikin kayan farfajiyar, kuma yana bayyana matakai daban-daban da suka taimaka wajen siffanta shi. Gungura ƙasa don bidiyo. Ceres na iya zama kamar duniya ce mai ban tsoro, amma sabbin hotunan infrared sun nuna akwai abubuwa da yawa ga duniyar dwarf fiye da tunanin farko. Hotunan da aka ɗauka ta amfani da shuɗi (440 nanometers), kore (550 nanometers) da infrared (920 nanometers) an haɗa su don ƙirƙirar taswirar. 'Wannan dwarf duniya ba kawai wani inert dutse a ko'ina cikin tarihi. Yana aiki ne, da tsari da ke haifar da abubuwa dabam dabam a yankuna dabam dabam,' in ji Chris Russell na Jami'ar California, Los Angeles. Abubuwan 'baƙi' a farfajiyar, waɗanda aka kira fasali 1 da fasali 5, suna bayyana a cikin hotunan haske mai haske kamar walƙiya mai haske idan aka kwatanta da sauran farfajiyar Ceres. A cikin infrared, yankin 1 ya fi sanyi fiye da sauran farfajiyar, amma 5 yana cikin yankin da yake kama da yanayin zafi zuwa kewaye. A watan da ya gabata, masana kimiyya sun ce wannan ma'aurata masu haske masu ban mamaki za su iya zama 'volcanoes na ruwa', amma sun ce suna bukatar su duba da kyau don tabbatar da wannan. Federico Tosi, wanda ke aiki a Dawn's Visible and Infrared Spectrometer, ya gabatar da hotunan infrared na tabo biyu, yana auna kaddarorin su na zafi. 'Abin da muka gano shi ne cewa tabo mai haske lamba daya ya dace da tabo mai duhu a cikin hoton zafi,' in ji shi a wani taron manema labarai a yau. An kama su ta hanyar binciken Dawn daga nisan mil 28,000 (45,000km), hotunan sun bayyana cewa haske biyu masu haske a farfajiyar suna da kaddarorin zafi daban-daban.
Hotuna daga Dawn sun bayyana wuraren da ba a sani ba a farfajiyar, wanda aka kira fasalin daya da fasalin biyar, a cikin infrared. Feature daya ne mai sanyaya fiye da sauran surface, amma bayar da shi ne a cikin wani yanki da cewa shi ne kama a zazzabi zuwa kewaye. Ka'idar da ke jagorantar tabo ita ce cewa kankara da ke rufe ta da ƙasa mai laushi tana fashewa saboda matsin lamba a cikin asteroid.
