天文旅遊
加拿大世界第二暗空保護區JASPER NATIONAL PARK, CANADA
就是位於加拿大伯達省的「賈斯珀國家公園」，其幅員遼闊達一萬一千平方公里。
每年十月，遊客前往加「賈斯珀暗空節」，使該國家公園成為加拿大最佳天文旅遊勝地之一。
白天時，遊客可以欣園區的冰川、溪流、湖泊及山巒美景。
智利
智利每年平均三百天有晴朗的夜晚，是天文旅遊的絕佳去處。
晴朗的夜空意味著遊客非常有可能得以看見繁星滿天，因為少了雲層阻擋視線。
芬蘭
芬蘭北部是全球觀賞北極光的最佳地點之一。
北極光以簾幕狀、弧狀、螺旋狀等光束形態呈現；常是綠色，不過也可能是粉紅色及更為罕見的紅色和藍紫色。
北極光是太陽射出的帶電粒子與地球大氣及磁場交互作用的結果。
在芬蘭拉普蘭地區，一年就有兩百個夜晚可以看到極光。
無論你去到何處，天文旅遊能讓你有機會稍作停留，思考宇宙奧妙之處。
