Why is the Aurora Borealis above Greenland green?
Green is the commonest color in the Aurora Borealis as green is produced when charged particles from the sun collide with atoms of oxygen at a high level. The Aurora over Greenland would sometimes show colors of blue and red, though probably not as often.
What is the usual color of aurora borealis?
The usual color of aurora borealis, also known as the Northern Lights, is green. This is caused by charged particles from the sun interacting with the Earth's atmosphere. However, depending on the altitude and the type of gas particles involved, aurora borealis can also appear as red, pink, purple, blue, or yellow.
Are the Aurora Borealis on Earth caused by sunspots?
Yes, the auroras begin as sunspots, or solar flares. Charged particles stream out from the sun and collide with atoms of oxygen and nitrogen in the earth's ionosphere. The oxygen and nitrogen give out green, blue and red light, the same way a neon tube works.
Why do we see specific colors in the Aurora borealis?
The specific colors in the Aurora Borealis are primarily due to the interaction between charged particles from the solar wind and the Earth's atmosphere. When these particles collide with gases like oxygen and nitrogen at high altitudes, they excite these atoms, causing them to release energy in the form of light. Oxygen typically produces green and red hues, while nitrogen can create purples and blues, resulting in the stunning color display we observe in the auroras. The variations in color also depend on factors like altitude and the type of gas involved in the collisions.
Does Aurora borealis emit light?
Yes it does, solarly charged electrons from the sun fall towards Earth at over one million miles per hour, it takes the electrons roughly 40 hours to reach Earth. When they fall towards the magnetic poles the charged electrons collide with nitrogen and oxygen atoms in the gaseous atmosphere, the knock an atom's electron off course and when it returns to the correct orbit the atom releases a photon. Photons are light particles, so yes the aurora borealis does emit light.

When did Aurora Borealis exist?
The aurora borealis is located in the arctic. They are so bright that people think that it is brighter than the sun. The colours of these lights can be green, yellow, reed, orange, violet and blue. The aurora started when the earth begun more than 60 million years ago just before the dinosaurs started.
Is the Aurora Borealis caused by humans or nature?
An Aurora Australis or an Aurora Borealis occurs when streams of particles from the sun's solar winds hit the earth's atmosphere at an angle (as can only happen at the poles). These particles interact with the edges of the earth's magnetic field and when they collide with the gases in the ionosphere, the particles glow creating curtains of blue, green and magenta. An aurora is sometimes accompanied by a crackling sound.

What are some of the colors you can find in the Aurora Borealis?
Any color on the light spectrum. This is violet, blue, red,orange, yellow, and green, with violet being the lest common, and green the most common

Are the Auroras the same?
The Northern Aurora (Borealis) is much the same as the Southern Aurora (Australis), except they are at different ends of the earth. Each time an aurora lights up it is different, as it depends on the numbers of charged particles and how and at what level they collide with the atoms of oxygen and nitrogen in the earth's ionosphere. They may show great wavy swirls of green, like gigantic strands of seaweed, or a great red glow, like bushfires over the horizon.
