Why does the Northern Lights happen?

What causes the Northern Lights? The Northern Lights are actually the result of collisions between gaseous particles in the Earth's atmosphere with charged particles released from the sun's atmosphere. Variations in colour are due to the type of gas particles that are colliding.

What are the Northern Lights in simple terms?

The Northern Lights, Aurora Borealis, appear in a clear night sky as swirling rivers of greenish-blue light. They move and dance unpredictably; sometimes barely perceptible, then suddenly growing vivid. In simple terms, the auroras can be explained as an interaction of the solar wind and the Earth's magnetic field.

What are the Northern Lights and where can you see them?

The best places in the world are usually closer to the Arctic Circle, including Alaska, Canada, Iceland, Greenland, Norway, Sweden and Finland. But don't limit yourself: You can also spot the southern lights in the southern hemisphere. Still, the northern lights are the star of the show.

Why are the Northern Lights green?

The most common color 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 they decay back to their original state, when they emit the green hue we can see from the ground.

What is the rarest aurora color?

green

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 the human eye see the Northern Lights?

Yes. Most commonly the aurora seen will be green or whitish, but depending on the strength of the activity, pinks and reds are also visible to the naked eye. The sensitivity of a person's eyes will also be a factor.

Why do aurora borealis have different colors?

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.

Where in the US can you see the Northern Lights?
