Green Aurora Over Lake Superior

Auroras are sparked by energetic particles from the sun interacting with the magnetic environment that surounds the earth. These particles come from Solar Flares caused by the earth's atmosphere. The resultant particles are electrons and protons, which, when they impact the oxygen particles in the atmosphere generate a green light.

The Gum Nebula

The Gum Nebula is named after it's discoverer: Mr. Gum. The red effect is caused from the gigantic cloud of Hydrogen Gas. It is supposivly over a million year old remenant of a supernova. It is rather faint though incredibly large, sprawling across the Vela and Puppis constellations. It is seen as a faint grey light to the naked eye.
