What are those bright spots on asteroid Ceres? As the robotic spacecraft Dawn approaches the largest asteroid in the asteroid belt, the puzzle only deepens. Sharper new images taken last week and released yesterday indicate, as expected, that most of the surface of dwarf planet Ceres is dark and heavily cratered like our Moon and the planet Mercury. The new images do not clearly indicate, however, the nature of comparatively bright spots — although more of them are seen to exist. The enigmatic spots were first noticed on Texas-sized Ceres a few weeks ago during Dawn’s approach. The intriguing mystery might well be solved quickly as Dawn continues to advance toward Ceres, being on schedule to enter orbit on March 6. Poll: What do you think the light spots on Ceres are?

🌌🔭 在矗立於小行星帶中的矮行星 Ceres 上，那些明亮的斑點到底是什麼呢？隨著機器人太空船 Dawn 接近這個最大的矮行星，這個謎團只會愈加深奧。新的圖片顯示，Ceres 大部分表面呈現出像我們的月球和水星那樣的黑暗、滿布隕石坑的樣貌，然而這些比較明亮的斑點的性質仍然不明。最近的影像顯示，比較明亮的斑點數量增多但具體原因仍然未清楚。隨著 Dawn 繼續向 Ceres 靠近，預計將於 3 月 6 日進入軌道，這個謎題很可能會很快得到解答。
