What if you could stand at the top of a volcano and peer out across the universe? If the timing is right, you might see an amazing panorama like the one featured here. In this case, the volcano is the Hawaii’s Mauna Kea, and the time was a clear night last summer In the foreground of this south-facing panorama lies a rugged landscape dotted with rocks and hardy plants. Slightly above and further out, a white blanket of clouds spreads horizontally to the horizon, seemingly dividing heaven and Earth. City lights illuminate the clouds and sky on the far left, while orange lava in the volcanic caldera of Kilauea lights up the clouds just left of center. The summit of an even more distant Hawaiian volcano, Mauna Loa, is visible in dark silhouette near the central horizon. Green airglow is visible above the clouds, caused by air molecules excited by the Sun during the day. The Moon is the bright orb on the right. A diffuse band of light-colored zodiacal light extends up from the far right. Most distant, the dramatic central band of our Milky Way Galaxy appears to rise vertically from Mauna Loa. The person who witnessed and captured this breathtaking panorama stands before you in the image center. Follow APOD on: Facebook, Google Plus, or Twitter

想像一下，如果你能站在一座火山的頂端，俯瞰宇宙的壯麗景色。若時機恰當，你或許能看到一幅令人驚嘆的全景，如下圖所示。這裡的火山是夏威夷的瑪納基亞（Mauna Kea），時間是一個清晰的夏夜。
前景中，南面全景展現出一片崎嶇的地形，散布著岩石和堅韌的植物。稍微高出一點，遠處的雲層如白色的毯子，水平地延伸至地平線，似乎將天空與大地分開。在最左邊，城市的燈光照亮雲層和天空，而橙色的熔岩在基拉韋亞火山（Kilauea）的火山口中，正中央偏左的位置，照亮了雲層。更遠的地方，另一座夏威夷火山瑪納羅亞（Mauna Loa）的山頂在中央地平線上隱約可見，呈現黑色的輪廓。
在雲層上方，綠色的空氣發光可見，這是由於白天陽光激發空氣分子所致。右邊的明亮圓形物體是月亮，而在最右邊，模糊的淺色帶狀光線是黃道光。最遠處，我們的銀河系中央帶在瑪納羅亞的上方顯示出驚人的垂直姿態。捕捉這幅驚人全景的人，正站在圖像的中央。
