北极光的传说（The legend of the aurora borealis）
极光（aurora）来源于拉丁文伊欧斯一词。传说伊欧斯是希腊神话中“黎明”的化身，是希腊神泰坦的女儿，是太阳神和月亮女神的妹妹。长久以来，人们都各自发展出自己的极光传说，爱斯基摩人认为“极光，是鬼神引导死者灵魂去天堂的火炬。原住民则视“极光为神灵现身，深信快速移动的极光会发出神灵在空中踏步的声音，将取走人的灵魂，留下厄运”。比如在芬兰语中，北极光则被称为“revontulet”，直译过来就是狐狸之火。古时的芬兰人相信，因为一只狐狸在白雪覆盖的山坡奔跑时，尾巴扫起晶莹闪烁的雪花一路伸展到天空中，从而形成了北极光。
• Aurora comes from the Latin Word——Ios.
•Legend has it that Ios is the embodiment of the 'dawn' in Greek mythology, the daughter of the Greek god Titan, the sister of Phoebus and moon goddess.
• The aurora borealis has been a mystery since the first time humans looked up at the sky and saw the aurora borealis.
For a long time, people have developed their own auroral legend. The eskimos believe that
the aurora is the torch of spirits that lead the dead to heaven. The aborigines saw the aurora as a deities, convinced that the rapid movement of the auroras would send out the spirits of the gods in the air, and would take away the soul, leaving bad luck. In Finnish, for example, the aurora borealis is called "revontulet", and the literal translation is the fire of the fox. Ancient finns believed that because a fox was running on a snow-covered hillside, the tail swept the glittering snowflakes all the way up to the sky, creating the aurora borealis.
I prefer to believe the aurora borealis is a symbol of happiness.
极光形成过程（Aurora formation process）
北极光（aurora borealis），是出现于星球北极的高磁纬地区上空的一种绚丽多彩的发光现象，由来自地球磁层或太阳的高能带电粒子流（太阳风）使高层大气分子或原子激发（或电离）而产生。北极附近的阿拉斯加（欧若拉）、北加拿大是观赏北极光的最佳地点。
The aurora borealis is a gorgeous glowing phenomenon over a high magnetic latitude regio
n in the Arctic of the planet, generated by high-energy charged particle flows (solar wind) from the Earth's magnetosphere or the sun that excite (or ionization) the upper atmosphere molecule or atom. Alaska and Northern Canada, near the North Pole, are the best places to watch the aurora borealis.
极光的形态（the auroral shapes and colors）
极光是一种大自然天文奇观，它没有固定的型态、颜也不尽相同，颜以绿、白、黄、蓝居多，偶尔也会呈现艳丽的红紫，曼妙多姿又神秘难测。
一般来说，极光的型态可分为弧状极光、带状极光、幕状极光、放射状极光等四种。在北部出现的称为北极光，在南部出现的则称为南极光。
Aurora is a natural astronomical wonders, it has no fixed form, color is not the same, color to green, white, yellow, blue, and occasionally will appear gorgeous red and purple, graceful and mysterious and unpredictable.
In general, the auroral form can be divided into arc-like Aurora, ribbon Aurora, episodic Aur
ora, radial Aurora and other four kinds.
The Northern Lights, which appear in the north, are called the Aurora Borealis in the south.
极光的发生只有在严寒的秋冬夜晚，高纬度的地区，才有机会目睹，因为漆黑寒冷的夜晚北极光最易出现，所以最佳时刻则是11月至次年2月晚上10点到凌晨2点，有些时候可持续1小时左右。
Auroras occur only in the frigid winter and autumn evenings, where the high latitudes have the opportunity to witness, because the aurora borealis is most likely to appear in the dark, cold night, so the best time is from November to the following February to 2 o'clock in the morning, and sometimes lasts about 1 hours.
最常出没在北磁纬度67°附近的环状带区域内。北半球以阿拉斯加、北加拿大、西伯利亚、格陵兰冰岛南端与挪威北海岸为主。值得一提的是：北极附近的阿拉斯加、北加拿大是观赏极光的最佳地点，阿拉斯加的费尔班(Fairbanks)更赢得“北极光首都”的美称，以其寒冷的冬季与夏季的长时间光照而闻名，一年之中有超过200天的极光现象，人们去那里是为欣赏它
那壮观景象并目睹每晚都会出现的极光奇观。如果有机会到阿拉斯加，一定要看看那迷人的北极光，捕捉那千变万化的超级“电光秀”，将彻底地爱上北极光！中国最北的漠河，也可以观测到北极光。
Most commonly found in the annular zone near the North magnetic latitude 67°. The northern hemisphere is dominated by Alaska, northern Canada, Siberia, the southern tip of Greenland Iceland and the northern coast of Norway. It is worth mentioning: Alaska and northern Canada are the best places to watch the aurora borealis, and Alaska's Ferban (Fairbanks) wins the name of the northern Aurora Capital, known for its cold winters and long summer light, and over 200 days of auroral phenomenon in the year, People go there to admire its spectacular spectacle and to witness the spectacle of the aurora that will appear every night. If there is a chance to Alaska, be sure to look at that fascinating Arctic light, capture the ever-changing super 'electro-optic show', will completely love the Northern Lights! Northern China's most northerly Mohe can also observe the aurora borealis.
