5月31日，在这张从太空拍摄的地球边缘的8度宽视野中，记录了数十条平行的流星条纹。这张照片是由绕轨道运行的“阳王一号”太空望远镜拍摄的5分钟系列观测照片之一。它是在世界时03:43被捕捉到的，接近Tau大力神流星雨的高峰期。正如预测的那样，今年的流星雨很活跃，因为地球扫过了73P/Schwassmann-Wachmann 3号彗星解体后相对密集的碎片流，但没有明亮的流星。阳王一号图像中几乎所有的Tau大力神流星都太微弱了，地面仪器无法探测到。但在那天，在晴朗的天空下，耐心的地面观测者仍然欣赏到了令人难忘的Tau大力神号。

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.
