根据NASA的说法,英仙座流星雨被认为是一年中最壮观的流星雨,这要归功于它的“非常快和明亮的流星”,多伦多居民将能够在本周晚些时候的流星雨高峰期一睹这一现象。
每年从7月中旬到8月底,北半球都能看到英仙座流星雨,但预计今年8月11日和12日的晚上会达到顶峰。
Time to wish upon a star. The annual Perseid meteor shower will peak on August 12. The best time to look is in the pre-dawn hours, but midnight to dawn any morning the week before or after should produce a few meteors, including the occasional “fireball.” https://t.co/HTlEpYJJqp pic.twitter.com/ZZgC2aj9vC

根据美国宇航局的说法,“英仙座流星雨在穿越地球大气层时,经常会在身后留下长时间的光和颜色的‘尾迹’。”
英仙座流星雨是最多的阵雨之一(每小时可以看到50-100颗流星),并且出现在温暖的夏夜天气中,使天文观测者可以很容易地看到它们。
加拿大航天局表示,任何对周二晚上的流星雨感兴趣的人都应该在月落到黎明之间抬头仰望天空,以尽可能多地看到流星。
Next few mornings … Perseids peaking ☄️
In 2020, the peak morning of the Perseid meteor shower is most likely August 12, under a waning crescent moon. The mornings of August 11 and 13 are worth trying, too. Read more: https://t.co/MRkjaJMZFR 👓
