Works on creation of long-lived fireballs of the gas discharge origination have been carried out with a help of special designed gas discharge tubes, in which the condensed matter in a form of a specially prepared thread or powder material was deposited. Origination of long-lived luminescent spheres - fireballs has been detected. Some of them exploded during their lifetime. A nature of these objects is discussed. © 2012 by the American Institute of Aeronautics and Astronautics, Inc.
