Alaska Light Show (阿拉斯加的极光)
Alaska is known for its dark cold winters and long daylight summers. People venture there for its beautiful scenery， majestic vistas and to witness its spectacular light show virtually every night of the year.“ Witnessing the northern lights is spectacular. It's awe inspiring because you can't really explain what they are and why they are there，” a visitor said.In ancient times， mythological gods were credited with this creation. But these mysterious lights get their powerful glow from the same awesome force that gives our planet life.The sun is the source of energy for everything on planet earth， all life， all weather， and all activity that we know. Explosions and solar storms on the suITce of the sun send charged particles known as solar winds hurtling towards earth. When they reach the earth's magnetic field the energy is transferred into visual light around the earth's Polar Regions. Realize the earth has magnetic field lines that loop out into space from the northern hemisphere to the southern hemisphere， arching away from the earth and it is those magnetic field lines that organize the solar storms that cause it to create auroras.While scientists know the cause of the aurora， exactly how it affects earth is still in question. Though infrared cameras have captured solar storms， the aurora remains a mystery.For creating the planet's greatest nighttime light show， the aurora makes our list at number one.From the spitting lava of Kilauea， to the raging rapids3 of the Colorado， the natural wonders of the world are dynamic4 proof of this spectacular planet we call Earth. But ultimately it's our curiosity of their existence that's the most wondrous thing of all. And that is our honor to bear witness to the planet's finest legacythe Ultimate5 Ten Natural Wonders.阿拉斯加以其夜长昼短的阴冷夏日与长日照的夏日而闻名。人们冒险离开这里不雅观赏它美好的景致、绚丽的风景，并亲眼看看一年中几乎每晚都会出现的极光奇不雅观。“目击北极光好像身临仙境，奇幻之至，既愉快又令人敬畏，因为你无法注释它们是何物，为何而来，”一位旅客说。
在现代，人们以为是传说中的仙人发明了这种气象。但理想上，这种秘密之光的强度亮光来自于异样付与地球以生命的令人敬畏的力量。
太阳是地球上万物的能量之源，包括我们晓得的全部生命、全部气候和全部的活动。太阳表面的爆炸和太阳风暴，把带电粒子（即所谓的太阳风）狠恶射向地球。当它们到达地球磁场之后，能量便在地球极圈地带转化成可视的光芒。要晓得，地球上的磁场线以环形在空间从北半球抛向南半球，呈拱形笼盖于地球上空，而恰是这些磁场线关于太阳风暴的感化组成了极光。
固然迷信家晓得了极光的成因，可是它毕竟若何影响地球照旧一个疑问。虽然红外线摄像性可以捕获到太阳风暴，而极光仍然是一种秘密之物。
因为发明了地球上最庞年夜的夜光之舞，极光在我们的名单上排名第一。
从基拉韦厄火山喷涌而出的岩浆，到科罗拉多滔滔的激流，这些世界天然奇不雅观活泼地证明了我们称之为“地球”的这个星球是多么奇特、美丽。但是最终而言，全部当中最出色的照旧我们对这些景不雅观的猎奇心。可以见证这个星球上最好的遗产——十年夜天然奇不雅观，确实是我们的幸运。
