This phenomenon is called plasma spheres, based on the generation of very high voltage (10,000V) but with very little current (1 milliamp) to create static electricity which ionizes a gas, typically an inert gas like helium or neon. To find out more and even how to make one, check out the following website: http://www.amasci.com/tesla/plasplan.html.
