2022下半年已至，你準(zhǔn)備好奮斗了嗎？

Stars trail through a clear morning sky in this postcard from a rotating planet. The timelapse image is constructed from consecutive exposures made over nearly three hours with a camera fixed to a tripod beside the Forbidden City in Beijing, China on June 24. Arcing above the eastern horizon after the series of exposures began, a waning crescent Moon left the brightest streak and watery reflection. On that date the planets of the Solar System were also lined up along the ecliptic and left their own trails before sunrise. Saturn was first to rise on that morning and the ringed planet’s trail starts close to the top right edge, almost out of the frame. Innermost planet Mercury rose only just before the Sun though. It left the shortest trail, visible against the twilight near the horizon at the far left. Uranus and Neptune are faint and hard to find, but mingled with the star trails the Solar System’s planet trails are all labeled in the scene.

在這張來自旋轉(zhuǎn)行星的夜景明信片里，恒星曳著跡線穿過清朗的早晨天空。這幅記錄于6月24日的縮時影像，建構(gòu)自放在中國北京紫禁城旁的一部用三腳架固定之相機(jī)，于將近3小時期間連續(xù)拍攝的多張照片。在開始記錄影像序列之后，一輪殘月在東方地平線上方，劃出了帶有水面倒影的那道最明亮的跡線弧。而在那天，沿著黃道排列的太陽系行星，也在日出前各自曳出跡線。當(dāng)天早晨最早起的是土星，這顆環(huán)系行星的跡線起始于右上角附近，幾乎超出視框。而只比太陽稍早升起的最內(nèi)圍行星─水星，留下左側(cè)地平線曙光里依稀可見的最短跡線。暗淡的天王星及海王星之跡線，則與恒星的跡線混雜在一起難以分辨。這幅影像中的太陽系行星跡線皆已加上標(biāo)記。
