20080709 APOD：月光下的行星和火焰
影像提供及版权：Dmitrii Zagorodnov
说明：7月5日，迷离的行星，明亮的恒星，以及一轮新月优美地出现在日落后的西方天空中。沿着太阳系的黄道盘面排列，这三个天体形成了这张影像中引人注目的风景，与月球排列在一起的是土星（左上），然后是火星，最后是轩辕十四－狮子座α星。当然地球本身位于影像前景中，这就是加利福尼亚州、圣芭芭拉城市灯光的美景。而影像右侧的黑烟弥漫在城市的上空，这是由仍在燃烧中的森林大火造成。在星期四晚上，能看到土星与火星靠得很紧，形成了合，在天空中相互间距离仅仅3/4度。
Planets and Fire by Moonlight

Explanation: On July 5th, wandering planets, bright stars, and a young crescent Moon graced western skies after sunset. Arrayed along the solar system's ecliptic plane, the three celestial beacons forming this skyscape's eye-catching line-up with the Moon are Saturn (upper left), then Mars, and finally Regulus, alpha star of the constellation Leo. Of course planet Earth itself lies in the foreground, a scene dominated by the city lights of Santa Barbara, California. The smoky haze hanging over the city is from threatening wild fires still burning along the hill at the right. On Thursday evening, Saturn and Mars can be seen in a much closer pairing or conjunction, separated by only about 3/4 degree on the sky. |
