當 #極光 出現，居住於南北極圈的人會看見夜空有不斷變化的美麗光芒。很多人以為極光的形成與地球以外的太空無關，其實極光的成因與太陽黑子有很大的關係。 在我們介紹極光的成因之前，不如讓我們先對太陽作一點較深入的了解。大家都知道，太陽是一個十分熱的火球。它的表面溫度大約是六千度。每時每刻，太陽表面都會將大量粒子往外太空射出去。這就是天文學家經常提到的太陽風。 太陽黑子 在太陽表面，我們經常可觀察到一些黑色的東西，其實這些就是太陽黑子了。太陽黑子的溫度較太陽表面的平均溫度為低，大約是四至五千度。黑子也是磁場較強的地區，它附近經常會發生猛烈爆炸。這些爆炸會把很多高能帶電粒子從太陽表面發射到外太空去。其中一部份帶電粒子會隨著太陽風來到地球。 太陽表面的爆炸 我們知道，帶電粒子的運動是極容易受磁場所影響的。這些從太陽來的帶電粒子當然也不例外，它們會受地球磁場牽引，於南北兩極與地球大氣層的空氣粒子碰撞。大氣層的空氣粒子受碰撞後會發光，極光就這樣形成了。 轉載: http://www.phy.cuhk.edu.hk/…/dir_aurora/articles_aurora.html An aurora (plural: #auroras or aurorae),[a] sometimes referred to as polar lights, northern lights (aurora borealis) […]

“極光”(the Aurora) #歐若拉，北歐神話中掌管極光的女神，在北歐的冬季，有幸見到 #北極光 的人，也是上天眷顧的幸運兒，晴朗的夜空親歷北極光絢麗綻放，是一生一次妙不可言的浪漫體驗關於極光（Aurora）有各種各樣浪漫的傳說，中世紀早期，不少人相信極光是騎馬奔馳越過天空的勇士；在北極地區，因紐特人認為，#極光 是神靈在為最近死去的人照亮歸天之路；更有人相信對著極光揮手就會被它們帶走。不得不說，這些傳說帶來的神秘感讓極光更是有了些看頭。 "Aurora" #Aurora, the goddess of Aurora.
