The Aurora is a beautiful natural phenomenon caused by the excitation or ionization of molecules or atoms in the upper atmosphere by the Earth's magnetosphere or the solar wind, a high-energy charged particle flow from the sun. The Aurora is regarded as one of the most beautiful wonders in nature. There are many different types of Aurora, colorful, and in different shapes. Today, let's take a look at the scientific knowledge of the Aurora! Contents of this article 1. Is the Aurora during the polar day or polar night? 2. Where do the auroras appear? 3. Where do the auroras often appear? 4. Is the Aurora a light source? 1Are the Aurora Borealis during the polar day or polar night?Auroras can occur during both the polar day and the polar night. However, the sunlight during the polar day is too strong to be seen in the sun, so the beautiful auroras can usually only be seen at night. For example, the brightness of the discrete aurora at its brightest is enough to read books and newspapers at night, but it is not bright enough to be seen in the sun, so it can only be seen in the night sky. The aurora is a colorful plasma phenomenon caused by a stream of charged particles from the sun entering the Earth's magnetic field. The three conditions for the formation of auroras are: atmosphere, magnetic field, and high-energy charged particles. Auroras often appear in two ring-shaped areas near 67 degrees north and south latitude, and will appear brilliant and beautiful at night. 2Where do the Aurora appear?Auroras often appear in the sky near the Earth's North and South Poles. They usually appear at night as brilliant and beautiful lights. Auroras are a colorful plasma phenomenon caused by the flow of charged particles from the sun entering the Earth's magnetic field. Therefore, auroras often appear in the sky above areas with latitudes close to the geomagnetic poles and appear in the shape of bands, arcs, curtains, and radials. Auroras often appear in two ring-shaped areas near 67 degrees north and south latitude. For example, in Fairbanks, Alaska, auroras can appear at noon for more than 200 days a year. Iceland is located in the aurora belt and is a popular place to observe the aurora in the Northern Hemisphere. The Southern Lights can also be seen in high latitudes in South America, Australia, New Zealand and Antarctica. 3Where do the Auroras often appear?Auroras often appear over regions with higher latitudes on Earth, such as the skies above the North and South Poles. Auroras are a beautiful natural phenomenon caused by the excitation or ionization of molecules or atoms in the upper atmosphere by the Earth's magnetosphere or the sun's high-energy charged particle stream, the solar wind. There are three conditions for the production of auroras: the atmosphere, magnetic field and high-energy charged particles, and none of them can be missing. Iceland is also a popular place to observe the aurora in the Northern Hemisphere because the entire country is in the aurora belt. The aurora can also be seen in high-latitude Russia, Alaska, South America, Australia, New Zealand and Antarctica. The Aurora is regarded as one of the most beautiful wonders of nature. It comes in many different shapes, colors and styles. 4Is the Aurora a light source?Aurora is a light source. A light source refers to an object that can emit light and is emitting light. Aurora is a luminous phenomenon caused by the collision of charged particles from the sun with atoms in the atmosphere when entering the earth's magnetic field. It can emit colorful light and is a natural light source. Aurora occurs not only on Earth, but also on other planets in the solar system that have magnetic fields. The aurora appears in the sky above high magnetic latitudes. The generation of the aurora requires three conditions to be met, namely: atmosphere, magnetic field and high-energy charged particles, none of which can be missing. The aurora on Earth is a luminous phenomenon caused by the collision of charged particles from the sun with atoms in the atmosphere when they enter the Earth's magnetic field. It is a large-scale discharge process around the Earth. Auroras generally only appear in high-latitude areas at the North and South Poles, and are most likely to appear before the vernal and autumnal equinoxes. |
