The northern lights in time lapse

The northern lights, properly called the aurora borealis, are a natural light display in the sky caused by charged particles in the atmosphere being pulled around by the Earth’s magnetic field. When the particles collide and release energy, the lights appear.

This natural phenomenon is usually most apparent near the Earth’s poles (in the southern hemisphere it is called aurora australis, or “southern lights”) and especially near the equinoxes . Equinoxes are the time of year when the Earth’s axis tilts neither toward the sun (summer), nor away from it (winter). We think of the two annual equinoxes – the Vernal, or Spring Equinox, and the Autumnal, or Fall Equinox – as the beginnings of those seasons.

The auroras get their names from Aurora, the Roman goddess of the dawn. Various kinds of auroras can be seen all over the world and on other planets, too.

Norwegian landscape photographer Terje Sorgjerd spent a week in northern  Norway, near the Russian border, in 13 degree below zero weather, to make this magnificent time-lapse video of the aurora borealis. Other than time-lapse, there are no other special effects in this video – just an amazing light show provided by Mother Nature!
