Explanation: If you watch long enough, a comet will appear. Before then, you will see our Solar System from inside the orbit of Mercury as recorded by NASA‘s Parker Solar Probe looping around the Sun. The video captures coronal streamers into the solar wind, a small Coronal Mass Ejection, and planets including, in order of appearance, Mercury, Venus, Saturn, Earth, Mars, and Jupiter. Between the emergence of Earth and Mars, Comet Tsuchinshan-ATLAS appears with a distinctive tail. The continuous fleeting streaks are high energy particles from the Sun impacting Parker’s sideways looking camera. The featured time-lapse video was taken last year during Encounter 21, Parker’s 21st close approach to the Sun. Studying data and images from Parker are delivering a better understanding of the dynamic Sun’s effects on Earth’s space weather as well as humanity’s power grids, spacecraft, and space-faring astronauts.

说明: 如果你看得够久，迟早会出现彗星。在那之前，你会见到美国国家航空航天局的帕克太阳探测器在绕行太阳时，从水星轨道之内所拍摄的太阳系景观。这部影片记录了日冕流束向外伸展成为慢速太阳风、一例小型的日冕物质抛射，及先后出现的行星，依序分别有：水星、金星、土星、地球、火星和木星。在地球与火星之间的影片里，可以看到曳着明显彗尾的紫金山–阿特拉斯彗星。而画面中不断闪烁的短暂光痕，则是来自太阳的高能粒子轰击帕克号的侧视相机所造成的。这部主题缩时影片，是在去年于第21次近距离接近太阳时拍摄的。研究 帕克探测器的数据和影像，有助科学家深入了解太阳动态如何影响地球的太空天气，以及对人类的电力系统、航天器和宇航员可能的影响。
