One of the most amazing sites to see are the Polar Auroras which occur between the Sun and the Earth’s magnetic fields. Before scientific studies began which wasn‘t until the mid-1800s, people watched the auroras but worried about the danger that they may possess.
While learning about the Auroras, it is important to understand that there is a giant magnetic field surrounding the Earth. The Earth’s core is made up of metals which acts like a magnet. This creates a magnetic field known as the magnetosphere that extends deep into space. Because of this field, it affects nearby objects.
The Earth’s magnetic field varies in strength but the poles of the Earth are the strongest. In empty space, the Earth’s magnetic field does not exist. Although, the sun has a magnetic field too. Atomic particles are always boiling off the Sun and mo
When these particles make contact with the gas, the burst of color, which is higher than any of the highest jet planes fly, extend from 40 miles above the Earth to 600 miles above the Earth. There are some stories of the Aurora reaching down through the clouds or to the tops of the mountains but this is just an illusion or another phenomenon besides an aurora. Another belief about the auroras is that they create some sound. Although any noise generated by the aurora would take a long time to travel all the way down to Earth besides the air where the Aurora occurs is much too thin to carry sound.
rticles collide with nitrogen and oxygen gases. Nitrogen atoms give off blue light and Oxygen atoms give off green and red light. Although there are other gases in the ionosphere which give off some color, it is difficult for our eyes to see them.
