Explanation:
Scroll right to take in the view from the highest summit in the contiguous USA.The above 360-degree digitally stitched panorama, taken in mid-July, shows the view from 4,400-meter high Mt. Whitney in Sequoia National Park, California.In the foreground, angular boulders populate Mt. Whitney's summit while in the distance, just below the horizon, peaks from the Sierra Nevada mountain range are visible.Sky sights include light pollution emanating from Los Angeles andFresno, visible just above the horizon.Dark clouds, particularly evident on the image left well above the horizon, are the remnants of a recent thunderstorm near Death Valley.High above, the band of the Milky Way Galaxy arches across the image left.Bright airglow bands are visible all over the sky but are particularly prominent on the image right.The planet Jupiter appears as the brightest point on the image left.A discerning eye can also find a faint image of the far distant Andromeda galaxy, a satellite trail, and many constellations.Today marks the 100th anniversary of the completion of the historic stone shelter on Mt. Whitney, visible toward the image right. 今天的APOD大图实在太大，而且速度巨慢，我只给出链接，请大家自己去下载。

說明:
把視窗向右捲動，就可以觀賞美國這個地區最高峰的景觀。上面這幅數位嵌接的360度全景影像，今年7月攝於美國．加州美洲杉國家公園 (Sequoia National Park)惠特尼山 (Mt. Whitney)的4,400公尺頂峰。影像前景有惠特尼山頂峰無所不在的稜角石，在遠方的地平面之下，隱約可見到內華達山脈 (the Sierra Nevada)的群峰。地平面以上的天空景觀，有緊貼著地平面的洛杉磯和Fresno都市光害，影像左側地平面上方的烏雲，是不久之前死谷雷暴所留下的殘雲，更上空則可見到蜿蜒在影像左側的銀河系盤面。影像裡到處都可以見到帶狀的明亮大氣暉光，其中以影像右端的最為突出。影像左端最亮的天體是木星。眼晴敏銳的讀者還可以找到遙遠仙女座大星系的黯淡光暈、人造衛星流跡和眾多的星座。今天是惠特尼山頂緊急避難石屋啟用的一百週年，在影像右側可見到這座歷史性的建物。 ::070821_21.jpg::好美 27号的图，标题怎么写23号的？？ 5# 江涛
