Because electrons collide with gas particles most thickly around the poles, that's where you'll find the Alaska Aurora Borealis. The collisions of electrons with gas particles in our atmosphere give off energy, which forms the lights of the Northern Lights. These electrons are swept through the air by solar wind from the Sun.

The Colors of the Alaska Aurora Borealis
The lights of the Alaska Aurora Borealis often shine in a variety of dazzling and spectacular colors. Auroras can be yellow, orange, red, green, blue, you name it. The reason for this range of colors derives from what causes the Alaska Aurora Borealis. Auroras like the Northern Lights are formed when charger particles like electrons strike gas particles in our atmosphere.

p>Much like in neon lights, the color of the resulting light depends on what kind of gas is being struck. Some gas particles emit green light when struck by electrons, some emit red light, etc. This accounts for the astonishing variety of color to be found in the Alaska Aurora Borealis.

If you plan on seeing the Alaska Aurora Borealis, there are a variety of sources that can tell you when is the best time of year to go on a tour of the area. Local experts have a good sense of the best places and times to see the auroras, so it might be worth registering for a tour of the area. If you do decide to go see the Alaska Aurora Borealis, keep in mind that Alaska has many spectacular sights to offer, including some of the most stunning landscape and wildlife viewing around.
