Also know as the Aurora Borealis, these lights are best viewed in the cold dark winter months. The beautiful blaze of the Northern Lights, or Aurora Borealis, begins when energetic electrically charged particles accelerate along the magnetic field lines into the upper atmosphere, where they collide with gas atoms, causing the atoms to give off light. The air lights up rather like what happens in a fluorescent light tube. The aurora colors reflect gases, the most usual yellow-green color coming from oxygen. Red coloring is also due to oxygen with a contribution from nitrogen and violet is due to nitrogen. The charged particles originate from the sun, and it is the “weather” conditions on the sun that decide whether or not we will see the aurora. Low on the horizon a faint glow of greenish light which forms an arch, stretching lazily across the sky can be seen in the night. Additional bands of light form and drift overhead, slowly brightening to form giant curtains in the sky that slowly wave like a gentle breeze blowing. The bottom of the curtain brightens with a reddish tint and ripples faster. Blues and purples appear as the curtains pass directly overhead. Bright points of light swirl like a pinwheel. The entire sky seems to be full of color and motion. Then, after a few hours, the lights fade into a warm green glow. Polar Bears are up to 10 feet (3 m) long and weigh about 1,700 pounds (770 kg); males are bigger than females. Polar bears have a small head, powerful jaws, and a black nose and tongue. They have a strong sense of smell. Their tail is small and flat. They have wide front paws with slightly webbed toes that help them swim. Polar Bears have two types of fur. They have thick, woolly fur close to the skin that keeps them warm. They also have hollow guard hairs that stick up and protect the bears from getting wet. This print is treated with an ultra violent protective coating. It will be rolled and inserted into a mailing tube. I will also insert a sheet with information about this print. The print will be mailed first class by the U.S. Postal Service and insured. |
