What are the Northern Lights?

He Aurora borealis have fascinated humans for centuries. The incredible natural light show has been associated with many legends and tales over the years, but the phenomenon is actually caused by the interaction between charged particles from the sun, the Earth's magnetic field, and atmospheric gases.

Aurora borealis

He Aurora borealis They appear when tiny electrically charged particles from solar winds collide and excite gas atoms in the Earth's atmosphere. The atoms emit the colored light we call Aurora borealis.

Auroras are mainly observed near the Earth's poles, where the magnetic field is not as good at deflecting charged particles from the solar winds.

What is an aurora?

A dawn It is a natural display of colored light.

Where do auroras occur?

Auroras occur mainly near the Earth's poles. In the northern hemisphere, the northern lights are called Northern LightsIn the southern hemisphere, the northern lights are called aurora austral.

Where can you see the Northern Lights?

The Northern Lights can usually be seen in northern Canada, Alaska, Greenland, Scandinavia and Russia.

Where can you see the Northern Lights?

He southern lights They are more difficult to see as they occur mainly over Antarctica.

Why do the northern lights have colors?

The colours of the aurora borealis depend on the gas particles involved in the collision with the solar wind particles. The red and green colours are from excited oxygen atoms, and pink and blue are from nitrogen atoms.
