Planet Parade over Sydney Opera House

Explanation: The world is waking up to a picturesque planet parade. Just before dawn, the eastern skies over much of planet Earth are decorated by a notable line of familiar planets. In much of Earth’s northern hemisphere, this line of planets appears most nearly horizontal, but in much of Earth’s southern hemisphere, the line appears more nearly vertical. Pictured over the Sydney Opera House in southern Australia, the planet line was captured nearly vertical about five days ago. From top to bottom, the morning planets are Saturn, Mars, Venus, and Jupiter. As April ends, the angular distance between Venus and Jupiter will gradually pass below a degree as they switch places. Then, as May ends, Jupiter will pass near Mars as those two planets switch places. In June, the parade will briefly expand to include Mercury.

说明: 全世界正为美丽如画的行星游行而早起。在黎明前,地球大部分地区的东方天空有行星连珠为饰。在地球北半球的大部分地区,这条行星连珠几乎水平分布,然而在地球南半球的大部分地区,这道连珠却接近垂直。举例来说,在上面这幅5天前摄于澳洲南部的影像里,行星连珠几乎垂直悬挂在悉尼歌剧院的上空。从上到下,这些出现在清晨的行星,分别有土星、火星、金星和木星。在4月底时,金星和木星之间的角间距,会随着它们交换位置而逐渐降到1度以下。在5月底时,木星会通过火星附近,然后二者交换位置。在6月,水星将短暂加入这场行星聚会。
