The unique colors of light produced by a gas are called its “spectrum”. The auroral lights’ colors are determined by the spectra of gases in the Earth’s atmosphere, and the height at which the most collisions take place. Incoming particles tend to collide with different gases at different heights.
What elements give off colors in an Aurora?
Oxygen gives off the fluorescent green and yellow colour of the aurora (most common) when hit by electrons in the solar system. Nitrogen causes blue or red colours and sometimes pink, while neon turns them orange.
What causes the red color in an Aurora?
Reds appear in the Aurora when solar particles react with Oxygen at higher altitudes, generally above 150 miles. At this height the Oxygen is less concentrated and is “excited” at a higher frequency or wavelength than the denser Oxygen lower down making reds visible.
What is the rarest aurora borealis color?
It’s extremely rare to have an aurora without green. Green is the color people usually have in mind when they think of aurora. Above ~250km of altitude, the entities are extremely isolated and scares. The general density of the atmosphere is so low that particles rarely bump into each other anymore.
Can auroras be white?
Auroras get their colors from specific elements in Earth’s upper atmosphere. Green auroras, for instance, come from atomic oxygen; blue is associated with molecular nitrogen. No element produces white.
What causes the green color in Northern Lights?
The most common colour seen in the Northern Lights is green. When the solar wind hits millions of oxygen atoms in the Earth’s atmosphere at the same time, it excites the oxygen atoms for a time and then they decay back to their original state, when they emit the green hue we can see from the ground.
Can the Northern Lights be different colors?
The Aurora Borealis is most often seen in a striking green color, but it also occasionally shows off its many colors ranging from red to pink, blue to purple, dark to light. The reason that the aurora is seen in so many colors is that our atmosphere is made up of many different compounds like Oxygen and Nitrogen.
What is a green aurora?
Light green auras may feel a desire to embark on a meaningful or healing journey, Hira says, adding, “They are seeking to heal themselves first before they go out into the world to use their healing powers on others.” They make also place importance on their well-being, with Hira noting they can be drawn to read
What is white aurora?

Why don’t we see auroras on the moon?
Since the moon has no magnetic field and only a very thin atmosphere, there are no aurorae on the moon. Mars is a bit different. It does have an atmosphere, but does not have a magnetic field, however a type of aurora has been observed on Mars.
Can Northern Lights be pink?
On rare occasions, sunlight will hit the top part of the auroral rays to create a faint blue color. On very rare occasions (once every 10 years or so) the aurora can be a deep blood red color from top to bottom. Pink hues may also be seen in the lower area of the aurora.
How many colors are in the Northern Lights?
Known colors for Northern Lights are Green, Pink, Red and Green mixture, Pure Red, Yellow, Pure Blue, Orange and White. Human eye also detects green more readily than other colours.
Is pink aurora rare?
Cameras are designed to see colors much the way our eyes do, so the aurora looks pink in pictures as well. Pink aurorae aren’t unknown, but it is rare to see the color this strongly with no almost no other coloring at all.
Can you see the Northern Lights with your naked eyes?
Auroras appear to the naked eye as a very faint, white glow in the night sky to the magnetic north. Many auroras are totally invisible to the naked eye or can only be seen by looking at them indirectly, i.e. out of the corner of your eye. It is extremely rare to see them in colour with the naked eye.
Are red auroras rare?
Great red auroras are rare because they require a perfect mix of heavenly conditions. “To get a pure red aurora, you need two things from the sun,” Deehr said.
What country has the best view of the Northern Lights?

- Swedish Lapland.
- Reykjavik, Iceland.
- Yukon, Canada.
- Rovaniemi, Finnish Lapland.
- Ilulissat, Greenland.
Are there southern lights?
In the Southern Hemisphere, it’s the aurora australis, or southern lights. The name is different and it turns out that the view from each pole can be different too.
What causes the Northern Lights to dance?
Scientists have known for years that these undulating auroras are caused by a storm of charged particles high above Earth. And although a sight to behold, the forces triggering these lights can endanger satellites and air travelers near the poles.
Is the aurora borealis always green?
Green is the most common color observed but the Northern Lights can also appear white-gray. And a cloudy night if you’ve never seen them before, you might not even be entirely sure of what you’re looking at.
How do I know my aura color?
