说明:这张来自地球的明信片呈现了厄尔布尔士山区中阿兰丹湖上空的春季夜空美景。在这幅拍摄于4月17日当地午夜之后的影像中,中央银河正在该地区的东南地平线上空升起。沿着我们银河系平面的恒星和星云发光迹线被反射在镜子般的湖面上。而与弥漫的银河星光混合在一起的最亮天体是木星。稍暗一点的土星就位于山脉上空的左下方。当春天给树木带来新叶,将银河中心带到北天夜晚时,摄影师发现青蛙开始鸣叫,听起来像是从平静水面传来的美妙旋律。

Milky Way in Northern Spring

Explanation: A postcard from planet Earth, this springtime night skyscape looks over Alandan lake in the Alborz mountains. Taken after local midnight on April 17, the central Milky Way is rising over the region’s southeast horizon. Its luminous track of stars and nebulae along the plane of our galaxy are reflected in the mirror-like lake. The brightest celestial beacon mingled with the diffuse galactic starlight is Jupiter. Slightly dimmer, Saturn is below and left just above the mountains. As spring brought leaves to the trees and the galactic center to the northern night the photographer found it also gave frogs their voices, heard like a melody across the calm water.
