Amazing footage of the Northern Lights

A BBC film crew has captured spectacular footage of the Northern Lights.

The Northern Lights - also called the Aurora Borealis - are a colourful light show that occurs naturally in the sky in the northern hemisphere.

The light show occurs because of storms that take place on the surface of the sun - but they aren't like the storms on Earth.

These storms send out radiation, called the solar wind, that lights up the sky when it collides with Earth's magnetic field at the poles.

Scientists in Alaska near the North Pole hope to learn more about these storms.

They're taking measurements of the winds in the Earth's atmosphere during the light displays, so they can get a better understanding of how the solar winds affect them.

It's important for the scientists to find out more about the storms because they can interfere with satellites, power grids and communication systems.
