说明:尽管天气寒冷,但是有机会看到闪烁的北极光,这位天文观测者被哄到位于基威诺半岛西海岸的苏必利尔湖冻结的湖面上,我们将这幅夜空美景作为一个奖励送给他。在这幅拍摄于2月28日晚上10点至3月1日凌晨1点间的全景合成影像中,还可看到北半球冬末的夜空天象。在影像左侧,一道黯淡的黄道光带穿过火星和昴宿星团、从地平线上快速升起。遥远的星系M31和我们的银河系都在绿色的极光光弧上方闪耀。用来导航的北极星位于影像的中心上方,其右侧是北半球夜空中最易辨认的星群-北斗七星。陆地上的灯光包括了位于影像中心附近远处地平线上两个防浪堤的警示灯。

A Symphony in Northern Winter Skies

Explanation: Despite the cold, a chance to view the shimmering northern lights coaxed this skygazer onto the frozen surface of Lake Superior on the west coast of the Keweenaw Peninsula and offered this nocturnal crescendo as a reward. A northern late winter night sky also plays across the panoramic composition of images made between 10pm and 1am on the night of February 28/March 1. At left, a faint band of Zodiacal light rises sharply from the horizon crossing Mars and the Pleides star cluster. Both the distant galaxy M31 and our own Milky Way shine above the greenish auroral arc. Navigational north pole star Polaris is centered above and accompanied on the right by the northern night’s most recognizable asterism, the Big Dipper. Terrestrial lights include markers for two breakwaters on the the horizon near the center of the scene.
