南三角座流星雨和英仙座流星雨将点亮七月和八月的夜空
摘要
南三角座流星雨和英仙座流星雨将在北半球从七月开始可见，预计七月底和八月中旬达到观测高峰。观星者建议选择黑暗地点，并朝向相应的星座以获得最佳观赏体验。
今年夏天，北半球将迎来两场主要的流星雨——南三角座流星雨和英仙座流星雨。根据美国流星学会的资料，南三角座流星雨将于7月18日至8月12日期间出现，7月29日和30日达到高峰。观测者在黑暗的天空下朝南方望去，预计每小时可见15至20颗流星。该流星雨源自1986年发现的96P/Machholz彗星，这颗彗星在绕太阳运行时会留下碎片轨迹。 英仙座流星雨被认为是最壮观的年度流星雨之一，将于7月17日至8月23日可见，8月12日和13日达到高峰。然而，渐亏的盈凸月亮亮度可能会降低高峰期的能见度。最佳观测时间是在黎明前，当英仙座的辐射点位于天空最高处时。美国流星学会报告称，在乡村地区，观测者每小时可能看到50至75颗流星。英仙座流星雨由Swift-Tuttle彗星的碎片产生，该彗星于1862年由天文学家刘易斯·斯威夫特和霍勒斯·塔特尔发现。 为了获得最佳的流星雨观测体验，专家建议选择远离城市灯光的地点，给予眼睛15至20分钟适应黑暗，并朝向相关星座——南三角座流星雨朝南，英仙座流星雨朝东北方向的英仙座。携带毯子或椅子，并根据天气适当着装，也能提升观赏体验。
