英仙座流星雨将于八月中旬在美国达到高峰

摘要

英仙座流星雨将在8月12日晚至8月13日凌晨达到高峰,在美国的无光污染地区每小时可见多达100颗流星。

一年一度的英仙座流星雨预计将在8月12日晚至8月13日凌晨达到高峰,为美国各地的观星爱好者提供每小时多达100颗流星的观测机会,尤其是在光污染较少的地区。

英仙座流星雨的可见期为7月中旬至8月底,但今年的高峰预计将于当地时间8月12日晚上11点左右开始,持续至黎明。流星雨的形成是由于地球穿过斯威夫特-塔特尔彗星遗留的碎片,这些碎片在大气层中燃烧,形成明亮的流星划过天空。这些流星通常大小如沙粒,极少落地。

该现象在北半球最易观测,但中南纬度地区也能看到。观测者建议选择远离人工光源的开阔地带以获得最佳视野。根据美国宇航局(NASA)的介绍,流星似乎从英仙座星座辐射出来,英仙座可以通过先找到仙后座星座来定位。无需望远镜或双筒望远镜,但建议让眼睛适应黑暗约30分钟。

英仙座流星雨是每年八月的固定天文事件,专家指出,2028年该流星雨有望增强,成为更为壮观的流星风暴。
