加拿大这两天可见到美丽极光！昨晚和今晚（3月17日和18日），如果夜间天气晴朗，包括安省大多伦多在内的加拿大大部分地区有很大机会可以在北部夜空中看到美丽的北极光！不过要找灯光少暗的地方观看。
Canadians across the country were given a chance to witness a spectacular show Tuesday night as the northern lights were visible in many provinces -- provided you could find somewhere dark enough to view them.
The phenomenon occurs when charged particles collide with gases in the upper atmosphere of the Earth to produce a colourful show.
Strong blast of plasma from sun smacks Earth, may pull northern lights show south

The northern version, which Canadians see, is called aurora borealis, while the one seen in the southern hemisphere is called aurora astralis.
Astronomy North, a society dedicated to raising awareness about the northern lights, issued an alert on Tuesday, highlighting the fact there was a perfect blend of factors to make the lights highly visible.
The lights are also expected to be viewable on Wednesday.
If you missed a glimpse of the lights, you can head here to check out video streams of aurora borealis in Yellowknife, otherwise check out a collection of images below.
