Can orange be a color of northern lights?

Answer 1

Three colors generally.

The main color is green, then blue and finally red. It depends on what gas is involved and how high in the ionosphere the reaction takes place.

• Oxygen gives off green light usually, or sometimes browny-red.
• Nitrogen gives off blue or red.
• If the collisions take place high up then oxygen gives off red. Lower down oxygen gives green and nitrogen shines blue and red. Lower down still oxygen is quiet and nitrogen still gives off blue and red.

Pink,Green,Yellow,Orange and a violet colour

Answer 2

Charged particles from the sun come to the magnetic poles of the earth and, high up in the ionosphere, they collide with atoms of oxygen and nitrogen.

• Oxygen gives off green light usually, or sometimes browny-red.
• Nitrogen gives off blue or red.
• If the collisions take place high up then oxygen gives off red. Lower down oxygen gives green and nitrogen shines blue and red. Lower down still oxygen is quiet and nitrogen still gives off blue and red.

Answer 3

Stars have different colors because of differences in temperature (and composition). Below is a table (from user Myra Birgitte):

• Blue > 30,000 Kelvin
• Blue to blue white 10,000 -> 30,000 Kelvin
• White 7,500 -> 10,000 Kelvin
• Yellowish White 6,000 -> 7,500 Kelvin
• Yellow 5,200 -> 6,000 Kelvin
• Orange 3,700 -> 5,200 Kelvin
• Red 1,000 < 3,700 Kelvin
• Brown < 1,000 Kelvin
• Black 0 Kelvin

Answer 4

There are many different shapes, but often great swirling streams of green and blue rather like seaweed moving. Other times it is a steady glow without much movement.

The main colors are green, then blue, and more rarely red.

Answer 6

Nitrogen and oxygen, by far the two most prevalent elements in the atmosphere, are responsible for most if not all of the aurora.

Oxygen can be either green or red depending on the amount of energy absorbed.

Nitrogen can be either red or blue. The red line comes from it returning from an excited state to a ground state, and the blue comes from ionized nitrogen regaining an electron.

You'll notice that covers the three primary additive colors, so just about any color is possible from various mixtures of these thing happening. The most common, though, is green.

Answer 7

This is called the aurora borealis. Auroras occur when charged particles outside the Earth's atmosphere collide with atoms in the upper atmosphere. The result: a glowing display of curtains, arcs, and bands in the sky. The phenomenon is called aurora borealis or northern lights in the Northern Hemisphere and aurora australis or southern lights in the Southern Hemisphere.

Answer 8

The color you perceive a star as having is based on three or four factors.

1. The actual color of the star, which is driven by its size and age. As you would expect, a blue supergiant is blue and a red giant is red.

2. The red shift of the star based on its distance and motion away from us. This is what you're talking about, but I think it's a relatively minor issue.

3. The effect of atmosphere on the starlight.

4. Maybe some illusions added by your eyes and brain.

Now the question is "Why do stars TWINKLE different colors." That has nothing to do with the first two items. It has everything to do with air movement -- the atmosphere.

Answer 9

Three colors generally are in the Aurora Borealis and the Aurora Australis.

The main color is green, then blue and finally red. It depends on what gas is involved and how high in the ionosphere the reaction takes place.

• Oxygen gives off green light usually, or sometimes browny-red.
• Nitrogen gives off blue or red.
• If the collisions take place high up then oxygen gives off red. Lower down oxygen gives green and nitrogen shines blue and red. Lower down still oxygen is quiet and nitrogen still gives off blue and red.

Answer 10

In a neon or florescent light fixture, the glow in the tube is caused by running an electrical current through a near-vacuum with some trace elements. The type of trace elements determines the color of the light.

An aurora happens when a solar electromagnetic storm causes electrical currents to flicker through the near-vacuum high in the atmosphere, just like a neon light.
