An Experience of a Lifetime 追尋幸福極光!




The sun is a huge, fieryglobe of gas. Its power is not only limited to that gigantic globe, either. Occasionally, it sends out massive waves of chargedparticlesthat hit Earth at speeds upwards of a million kilometers an hour. These charged particles interact with our magnetic northern and southern poles, resulting in a breathtakinglight show that enthrallsall its viewers.



These light shows are known as auroras. Since Earth’s magnetic field is strongest at its poles, auroras appear most brightly near the North and South Pole. They are not seasonal because they occur at any time of the year. Some solar storms merely graze Earth and are only visible from the poles. A very large burst from the sun may, on the other hand, allow viewers in subtropical areas to witness one of nature’s most unusual displays of atmospheric cinema. The best viewing of auroras is in Alaska, northern Canada, Scandinavia, northern Russia, and the southernmost regions of Australia, South America, Africa, and Antarctica!



Auroras appear as slowly moving curtains, bands, spots of color, and a variety of other shapes that shift across the sky. They can also exhibit more than one color at a time. The colors, ranging from purple to green, depend on the altitude of oxygen and nitrogen penetrated by solar energy. The most common color on view is green, because it is at lower altitudes, and people can see green the easiest. Brownish-red auroras are created by higher-altitude, single-oxygen atoms. The rarest colors seen are pink, purple, and blue, which are the results of intense bursts of solar activity. Photographing all these colors of the breathtaking auroras is not difficult, but photos don’t do them justice. Viewing auroras is something that needs to be experienced in person.
