Aurora Lake Reflection Royalty Free Stock Photo When energetic particles from space collide with atoms and molecules in the atmosphere, they can cause the colorful glow that we call auroras. the colors of an aurora come from atoms and molecules being energized by colliding with energetic particles in the upper atmosphere. In the arctic they are called northern lights (aurora borealis); in the antarctic, the terms southern lights (aurora australis) are used. [2][3] auroras display dynamic patterns of radiant light that appear as curtains, rays, spirals or dynamic flickers covering the entire sky.
Aurora Reflection White 11oz Mug Iceland Photo Gallery The aurora borealis (northern lights) and aurora australis (southern lights) are the result of electrons colliding with the upper reaches of earth’s atmosphere. The uniform arc is the most stable form of aurora, sometimes persisting for hours without noticeable variation. however, in a great display, other forms appear, commonly undergoing dramatic variation. the lower edges of the arcs and folds are usually much more sharply defined than the upper parts. An aurora is a natural light display that shimmers in the sky. blue, red, yellow, green, and orange lights shift gently and change shape like softly blowing curtains. auroras are only visible at night, and usually only appear in lower polar regions. Find out what causes the northern lights and how you can see the aurora borealis.

Find out what causes the northern lights and how you can see the aurora borealis. How can i see the northern lights? we asked a nasa expert: episode 54. The aurora borealis and aurora australis are mirror images of each other. when the aurora becomes active in one hemisphere, it will become active in the other at the same time. A geomagnetic storm lies behind every inspiring aurora in our skies. the mystery behind these shimmering curtains of neon like light isn’t a mystery to scientists who study space weather. Images from spacecraft have given us the most spectacular view of aurorae. they show a continuous ring of aurora, or "auroral oval," around the polar cap, caused mostly by electrons leaking out along magnetic field lines from the plasma sheet of the earth's magnetic tail.
