天空中那些红色的细丝是什么？它们是一种罕见的闪电形式，大约35年前才被证实：红色精灵。研究表明，在强烈的云层对地面的正面雷击之后，红色精灵可能会以100米高的电离空气球的形式开始，以10%的光速从80公里高的地方射下来。紧随其后的是一组向上条纹化的电离球。这张特色照片是上月底在捷克共和国北部摩拉维亚的杰谢尼基山脉拍摄的。到红色精灵的距离约为200公里。红色精灵只需要不到一秒的时间就会出现，当强大的雷暴从侧面可见时，红色精灵就会出现。世界语言的APOD：阿拉伯语、保加利亚语、加泰罗尼亚语、中文（北京）、中文（台湾）、克罗地亚语、捷克语、荷兰语、波斯语、法语、法语（加拿大）、德语、希伯来语、印度尼西亚语、日语、韩语、黑山语、波兰语、俄语、塞尔维亚语、斯洛文尼亚语、西班牙语、台湾语、土耳其语和乌克兰语

What are those red filaments in the sky? They are a rarely seen form of lightning confirmed only about 35 years ago: red sprites. Research has shown that following a powerful positive cloud-to-ground lightning strike, red sprites may start as 100-meter balls of ionized air that shoot down from about 80-km high at 10 percent the speed of light. They are quickly followed by a group of upward streaking ionized balls. The featured image was taken late last month from the Jeseniky Mountains in northern Moravia in the Czech Republic. The distance to the red sprites is about 200 kilometers. Red sprites take only a fraction of a second to occur and are best seen when powerful thunderstorms are visible from the side. APOD in world languages: Arabic, Bulgarian, Catalan, Chinese (Beijing), Chinese (Taiwan), Croatian, Czech, Dutch, Farsi, French, French (Canada), German, Hebrew, Indonesian, Japanese, Korean, Montenegrin, Polish, Russian, Serbian, Slovenian, Spanish, Taiwanese, Turkish, and Ukrainian
