上帝视角看武仙座τ流星雨！

On May 31 tens of parallel meteor streaks were recorded in this 8 degree wide field of view of planet Earth's limb from space. The image is one of a series of 5 minute long observations by the orbiting Yangwang-1 space telescope. It was captured at 03:43 UT, near the peak of the Tau Herculid meteor shower. As predicted, the meteor shower was an active one this year, caused as Earth swept through a relatively dense stream of debris from disintegrating Comet 73P/Schwassmann-Wachmann 3, but was lacking bright meteors. Nearly all of the Tau Herculid meteors in the Yangwang-1 image are too faint to be detected by groundbased instruments. But on that date patient earthbound skywatchers under clear skies still enjoyed a memorable showing of the Tau Herculids.

5月31日，在这张8度宽的地球边缘空间视野中，记录到数十条平行流星条纹。这幅图像是绕轨道运行的Yangwang一号太空望远镜进行的一系列5分钟长的观测中的一幅。这张照片拍摄于UT03时43分，靠近武仙座流星雨的顶峰。正如预测的那样，今年的流星雨是一场活跃的流星雨，是由于地球穿过73P/Schwassmann-Wachmann 3号彗星解体产生的相对密集的碎片流而引起的，但没有明亮的流星。在Yangwang一号卫星的图像中，几乎所有的武仙座流星都太微弱，无法被地面仪器探测到。但在那个天，在晴朗的天空下，耐心的地面观测者们仍然欣赏着令人难忘的武仙座流星雨表演。
