Electrostatic discharge is a sudden and momentary flow of electric current between two differently-charged objects when brought close together or when the dielectric between them breaks down, often cr
A portion of a static discharger on an aircraft. Note the two sharp 3/8" metal micropoints and the protective yellow plastic.
A network card inside an antistatic bag, a bag made of a partially conductive plastic that acts as a Faraday cage, shielding the card from ESD.
Electric discharge showing the ribbon-like plasma filaments from multiple discharges from a Tesla coil.
Lightning is a natural phenomenon consisting of electrostatic discharges occurring through the atmosphere between two electrically charged regions. One or both regions are within the atmosphere, with

…breaks down, often creating a visible spark associated with the static electricity between the objects. ESD can create spectacular electric sparks (lightning, with the accompanying sound of thunder, is an example of a large-scale ESD event), but also less dramatic forms, which may be neither seen nor heard…
Strokes of cloud-to-ground lightning strike the Mediterranean Sea off of Port-la-Nouvelle in southern France.
A bolt from the blue lightning strike which appears to initiate from a clear patch of sky, but the turbulent sky above the anvil cloud drives a bolt of plasma through the cloud directly to the ground. They are commonly referred to as positive flashes, despite the fact that they are usually negative in polarity.
