金牛座流星雨:地球遇到恩克彗星的残留物,每年都会打来金牛座流星雨。由于残留物不是很密集的,所以金牛座流星数通常比较低,大约5颗每小时。但金牛流星群的特别之处是,他们往往是火流星。11月9日业余天文学家托马斯·阿什克拉夫特在新墨西哥东部拍下了一颗金牛座火流星爆炸的场面:点击以下图片可看视频“这个火流星亮度和满月差不多!” 说,阿什克拉夫特。崩解的火流星电离了空气,产生了无线电波。“视频中的声音是我记录的一些遥远的发射器在61.250兆赫和67.250兆赫的回声,”他解释说。 昨天晚上,11月9-10日,美国国家航空航天局的网络全天空火球相机抓拍到了10个金牛流星群,它们分别出现在美国南部。这些流星体的轨道都在以下图中,它们位于太阳系内,黄颜色的线便是它们的轨道: 在该图中,地球的位置是由一个红色图标表示的。昨晚的火流星并不是唯一的金牛流星群,换句话说昨晚残留物不是唯一一个撞击地球的。红色,橙色和绿色的轨道相对应的是随机的碎片,它们并不是恩克彗星的碎片流。 流星专家预报员预计11月12日的夜晚,周围的金牛座的火流星的数量将达到高峰。

原文: TAURID METEOR SHOWER: Earth is passing through a stream of gravelly debris from Comet Encke, source of the annual Taurid meteor shower. Because the debris stream is not very congested, Taurid meteor rates are usually low, around 5 per hour. The special thing about Taurids is that they tend to be fireballs. Amateur astronomer Thomas Ashcraft photographed this Taurid exploding over eastern New Mexico on Nov. 9th: "It was brighter than the full moon and its brightness penetrated the eyelids of sleepers!" says Ashcraft. The disintegrating meteoroid ionized a column of air that acted as a mirror for radio waves. "The soundtrack of the video is the echo of some distant transmitters I recorded at 61.250 MHz and 67.250 MHz," he explains. Last night, Nov. 9-10, NASA's network of all-sky fireball cameras recorded 10 Taurids streaking across the southern United States. The orbits of those meteoroids are color-coded yellow in this diagram of the inner solar system: In the diagram, the location of Earth is denoted by a red splat. Taurids weren't the only meteoroids hitting our planet last night. Red, orange and green orbits correspond to random debris not associated with Comet Encke's debris stream. Forecasters expect the Taurid fireball shower to peak on the nights around Nov. 12th. Monitor the realtime meteor gallery for the latest sightings.
