Explanation: The early morning planet parade continues. Visible the world over, the planets Jupiter, Venus, Mars and Saturn have been lining up in the pre-dawn sky since mid-April. In the featured image taken last month, these planets were captured over the Step Pyramid of Djoser, a UNESCO World Heritage Site. Located in the Saqqara necropolis of Egypt, the pyramid was constructed in the 27th century BC and is one of the oldest pyramids known. The two-image composite includes a foreground image taken during evening blue hour, and a background image captured from the same location the following morning. The morning planet line-up is slowly changing. At the end of last month, planets Jupiter and Venus switched places, while at the end of this month, Jupiter and Mars will switch after passing within one-degree of each other. Of course, this picturesque planetary angular alignment is a coincidence, as all of these worlds continue to orbit the Sun as they have for billions of years, well before even the ancient Pyramid of Djoser was built.

说明: 清晨的行星游行仍在持续。自4月中旬以来，全球皆可见到木星、金星、火星和土星，在黎明前的天空中呈排列成行。这幅摄于上个月的主题影像，呈现这些行星排列在左塞尔的阶梯金字塔（联合国教科文组织世界遗产之一）上空的景象。这座位于埃及的萨卡拉墓地之金字塔，建于公元前27世纪，是现知最古老的金字塔之一。这幅由2张照片合成的影像，包含了摄于傍晚蓝色时分的前景照片，以及第二天早上从同一位置拍摄的背景照片。清晨行星排列的方式正缓缓改变。在上月底，行星木星和金星互换了位置，而本月底，木星和火星将在靠近到1度以下后互换位置。当然这幅在视觉上如画的行星排列，只是一种巧合，因为有如远在左塞尔古金字塔建造之前的过去数十亿年一样，这些行星都将继续绕太阳运行。
