Explanation: What’s that small black dot moving across the Sun? Mercury. Possibly the clearest view of Mercury crossing in front of the Sun in 2016 May was from Earth orbit. The Solar Dynamics Observatory obtained an uninterrupted vista recording it not only in optical light but also in bands of ultraviolet light. Featured here is a composite movie of the crossing set to music. Although the event might prove successful scientifically for better determining components of Mercury’ ultra-thin atmosphere, the event surely proved successful culturally by involving people throughout the world in observing a rare astronomical phenomenon. Many spectacular images of this Mercury transit from around (and above) the globe were proudly displayed. The next transit of Mercury will take place in three weeks: on 2019 November 11.

说明：那个正在穿越太阳的小黑点是什么？那是水星。这可能是最清晰的一张水星凌日照片了，它摄于2016年5月。太阳动力学天文台对可见光波段和紫外光波段都进行了不间断的录制，之后通过导入音乐完成了这部水星凌日的视频。这次凌日过程让我们成功的对水星稀薄大气的成分进行了探测。然而更值得自豪的是这次水星凌日成功的吸引了全世界的人类参与到这次天象的观测中，所以这也是一次成功的天文文化活动。你可以通过搜索引擎找到（来自全球的）众多水星凌日的惊艳照片。水星下一次凌日是三个星期后的11月11日（2019年）
