主要是英仙流星群

探索宇宙（universe）！每天都会展示一张我们迷人宇宙的不同图像或照片，并附上一段由专业天文学家（astronomer）撰写的简短说明。

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

说明：这些图像记录于8月12日至13日夜间，由捷克一处天文台（astronomical observatory）的四台专用流星监测相机拍摄，经对齐和合成后形成了这张全夜全天视图。当晚，流星总数达到1,706颗。由于恰逢2026年英仙流星群（Perseids）的活动高峰，其中大多数是英仙流星群。它们数量众多，极易辨认。令人信服的是，英仙流星群的轨迹都追溯到右上方的同一个辐射点，该区域位于该年度流星雨同名的星座英仙座（Perseus）中。但通过寻找辐射点，也可以发现属于其他活跃度低得多的流星雨的流星。例如，可以看到穿过英仙流星群轨迹的流星来自一个辐射点位于天鹅座（Cygnus）的流星雨，即天鹅流星群（Cygnids）。反日点复合体（antihelion complex）是靠近宝瓶座（Aquarius）且在天空中与太阳相对的一般区域，也被识别为流星的一个弱源（weak source）。

Explanation: Recorded the night of August 12-13, images from four dedicated meteor-monitoring cameras at an astronomical observatory in Czechia were aligned and combined to create this all-night, all-sky view. On that night, the total count came to 1,706 meteors. And since that coincided with the peak activity of the 2026 Perseid Meteor Shower, most are perseids. Their overwhelming numbers make them easy to spot. Quite convincingly, perseid trails all trace back to a single radiant on the sky at the upper right, a region in the annual shower's eponymous constellation Perseus. But meteors belonging to other much less active showers can also revealed by finding their radiants too. For example, seen crossing the perseid trails are meteors from a shower whose radiant lies in Cygnus, known as Kappa Cygnids. The antihelion complex, a general region near Aquarius and opposite the Sun in the sky, is also identifiable as a weak source for meteors.
