\n\n Explanation: \nWhat created this large mountain on asteroid Ceres?\n\nNo one is yet sure.\n\nAs if in anticipation of today being \nAsteroid \nDay on Earth, the robotic spacecraft \nDawn in orbit around Ceres took the best yet image of an unusually tall mountain on the Asteroid Belt's largest asteroid.\n\nVisible at the top of the \nfeatured image, the exceptional mountain rises about \nfive kilometers up from an area that otherwise appears pretty level.\n\nThe image was taken about two weeks ago from about 4,400 kilometers away. \n\nAlthough origin hypotheses for the mountain include volcanism, impacts, and plate tectonics, clear evidence backing any of these is currently lacking. \n\nAlso visible \nacross Ceres' surface are some enigmatic light areas: \nbright spots whose origin and composition that also \nremain an \nactive topic of investigation.\n\nEven though Dawn is expected to continue to orbit Ceres, officially dubbed a \ndwarf planet, for millions of years, the \nhydrazine fuel used to point \nDawn's communications \nantenna toward Earth is expected to run out sometime next year.\n\n\n

\n\n Explanation: \nHow do sunspots evolve?\n\nLarge dark \nsunspots -- and the active regions that contain them -- may last for weeks, but all during that time they are constantly changing.\n\nSuch variations were particularly apparent a few weeks ago as the active region \nAR 2339 \ncame around the limb of the Sun and was tracked for the next 12 days by NASA's \nSolar Dynamic Observatory. \n\nIn the \nfeatured time lapse video, \nsome sunspots drift apart, while others merge.\n\nAll the while, the dark central \numbral regions \nshift internally and their surrounding lighter penumbras shimmer and wave. \n\nThe surrounding \nSun \nappears to flicker as the carpet of yellow \ngranules come and go on the time scale of hours. \n\nIn general, sunspots \nare relatively cool regions where the local \nmagnetic field \npokes through the Sun's surface and inhibits heating.\n\nOver the past week, an even more active region -- \nAR 2371 -- has been crossing the Sun and releasing powerful flares that have resulted in \nimpressive auroras here on Earth.\n\n
