The Department of Atmospheric Science at Creighton University has been actively looking for a little-understood phenomenon in the upper atmosphere. Referred to as "Red Sprites" and "Blue Jets", these events are characterized by the emission of reddish/orange and blue light coming from the top of thunderstorm clouds into the ionosphere. Believed to be somewhat similar to the Aurora Borealis, these lights in the sky are caused by the near visible emission of high energy electrons and other ions moving through the stratosphere/mesosphere.

Here's what a Red Sprite looks like!
