说明: 英仙流星从何而来? 它们的前世是含冰的砂砾微粒;更精确的说,英仙流星的前身是史威福特─塔托彗星[6]洒落在后方的碎片,这些流星体[7]在轨道上随着这颗彗星运行并逐渐扩散。 这部主题动画[8],呈现了整个流星体群在绕太阳[9]轨道上的演化。 当地球每年接近这个流星体群时,就会产生英仙流星雨[10]。 在动画中,以亮点显示的彗星碎片[11],基本上都太暗而难以侦测。 只有少部分的这些碎片会进入地球大气[12],受到加热,粉碎形成明亮的流星[13]。 今晚及后续数晚的夜空[14],将是英仙雨[15]及其他活跃流星雨[16]出没的好舞台,因为上弦月[17]在子夜前[18]就会西沉匿迹[19]。
