探索宇宙(Universe)!每天都会展示一张不同且迷人的宇宙图像或照片,并附上一段由专业天文学家(Astronomer)撰写的简短说明。

说明:这看起来像是从小王子的行星(Planet)上看到的景象。这张精选图像回顾了2024年的英仙流星雨(Perseid meteor shower),在投影中被波兰的比什恰迪山脉(Bieszczady Mountains)所环绕。天空中可见银河(Milky Way)的拱形,以及几片红色的星云(Nebula)和一百多颗指向辐射点的流星(Meteor)。英仙流星群(Perseids)在北半球(Northern hemisphere)的夏季很容易观测到,且非常受欢迎。(出于某种显而易见的原因,在冬季观测流星雨不太方便。)今年它们预计将呈现出比往常更加耀眼的景象,因为其极大期恰逢朔(New moon)。2026年的英仙流星雨将在今晚达到峰值,每小时流星数量可达50-100颗,届时地球(Earth)的轨道将穿过彗星(Comet)Swift-Tuttle留下的碎片。通常情况下,观测流星的最佳时间是在午夜到黎明前。你不需要双筒望远镜就能看到流星,但一把躺椅和一个黑暗的观测地点会有所帮助。
Explanation: It looks like a view from the Little Prince's planet. The featured image is a throwback to the 2024 Perseid meteor shower, surrounded in this projection by the Bieszczady Mountains in Poland. Visible in the sky is the arch of the Milky Way, along with several nebulas in red and over a hundred meteors pointing to the radiant. The Perseids are easily visible and quite popular in the Northern Hemisphere summer. (Watching meteor showers in the winter is less convenient for a good reason). This year they are expected to offer an even more dazzling spectacle than usual, because the peak coincides with a new moon. The 2026 Perseid meteor shower will peak tonight with as many as 50-100 meteors per hour, when the Earth's path crosses through debris left behind by Comet Swift-Tuttle. Typically, the best times for seeing the meteors are between midnight and pre-dawn. You won't need binoculars to see the meteors, but a lawn chair and a dark sky location help.
