The Aurura Borealis and Australis?

Question

Are they formed basically the same way a Cathode Ray Televison operates ? If So would it be possible to beam a giant TV into the sky using the earths Magnetic Field ?

Answer 1

Clost but no gold ring. The ozone layer is created when the solar wind collides with the earth's magnetic field. The beta particle is attracted to the north pole and make it negative. The alfa particles attracted to the south pole . These high speed particle beams become as a particle beam that blows a hole in the ozone layer. The one at the south pole is more pronounced because the mass of an alfa particle is much greater than the beta particle. This applies a huge battery across the earth that holds the O3 ions in place to protect us.

Answer 2

The Earth's magnetic field is only a distraction. The reason the Aurora occurs near the poles is that those magnetic field lines are open to electrons from the Sun, given the complex shape of the Earth's magnetic field. If you just want to write on the sky, a scanning beam of high-energy particles would actually make a better picture most other places on Earth.

The high-energy particles would have to be coming down from above. A high-energy beam from below would not deposit its energy in the correct layer of the atmosphere to stimulate an Aurora.

Answer 3

'Kinda' is the answer. They're formed as particles from the Solar Wind slide along the Earths magnetic lines of force and colide with various gasses in the ionosphere. But that glow is more like the glow in a neon light than the glow caused by electrons striking a phosphor coating on the face of a CRT.

Wow, talk about pollution! It wouldn't work. First of all, there's no way for us to send a beam of electrons through the atmosphere and secondly when you watch a CRT TV, you're looking at a layer or phosphorescent material. The atmosphere is more diffuse and dynamic so you wouldn't get a solid stable picture.
