What created these bright spots on Ceres? The spots were first noted as the robotic Dawn spacecraft approached Ceres, the largest object in the asteroid belt, in February, with the expectation that the mystery would soon be solved in higher resolution images. However, even after Dawn arrived at Ceres in March, the riddle remained. Surprisingly, although images including the featured composite taken in the last month do resolve many details inside Occator crater, they do not resolve the mystery. Another recent clue is that a faint haze develops over the crater’s bright spots. Dawn is scheduled to continue to spiral down toward Ceres and scan the dwarf planet in several new ways that, it is hoped, will determine the chemical composition of the region and finally reveal the nature and history of the spots. In several years, after running out of power, Dawn will continue to orbit Ceres indefinitely, becoming an artificial satellite and an enduring monument to human exploration.

🌌 你知道在小行星帶中，最大的天體——矮行星瑪賽拉 (Ceres) 上的那些亮點是由什麼造成的嗎？最初，這些亮點在機器人探測器“黎明號” (Dawn) 於二月接近瑪賽拉時被發現。隨著黎明號於三月抵達瑪賽拉，大家都期待能很快解開這個謎團，然而，即便是高分辨率的圖像也未能揭示真相。
在最近的合成圖像中，雖然顯示了奧卡托隕石坑 (Occator crater) 內部的許多細節，但謎底依然未解。值得注意的是，隕石坑的亮點上出現了一層淡淡的霧氣。黎明號將繼續下降至瑪賽拉，並以不同的方法進行掃描，期望能確定該區域的化學成分，最終揭開亮點的本質和歷史。
數年後，當解決電力問題後，黎明號將繼續在瑪賽拉軌道上運行，成為一個人工衛星，象徵著人類探索的持久紀念。🚀✨
