Explanation: The reddened shadow of planet Earth plays across the lunar disk in this telescopic image taken on May 26 near Sydney, New South Wales, Australia. On that crisp, clear autumn night a Perigee Full Moon slid through the northern edge of the shadow’s dark central umbra. Short for a lunar eclipse, its total phase lasted only about 14 minutes. The Earth’s shadow was not completely dark though. Instead it was suffused with a faint red light from all the planet’s sunsets and sunrises seen from the perspective of an eclipsed Moon, the reddened sunlight scattered by Earth’s atmosphere. The HDR composite of 6 exposures also shows the wide range of brightness variations within Earth’s umbral shadow against a faint background of stars.

说明: 这幅5月26日摄于澳洲新威尔斯悉尼附近的望远镜影像，记录地球红化影子落在月盘上所带来的景观。在这个清朗的秋夜，一轮近地点满月滑进地球黝黑本影的北缘附近。以月食的标准来说，这次的全食阶段只持续了短短的14分钟。不过，地球的暗影并非完全黝黑。从食月的方位看过来，地球的影子里，充斥着被地球日落及日出地区的大气红化及散射之阳光。这幅由6张照片合成的高动态范围影像，呈现了在暗淡背景恒星衬托下的地球本影，其实有很大范围的亮度变化。
