Electrostatic discharge. Spark of static electricity (purple) passing between two spheres. Static electricity is the accumulation of excess electrical charge in a region or on a surface. When there is enough electrical charge present to overcome the poor conductivity of the air, or enough attraction from a conductor, the charge will travel across the air space in the form of this electrostatic discharge.
