Lightning strikes Kavala, Greece. The ancient Greek god Zeus was said to control lightning, but today we know lightning comes from a difference in electrical charge between clouds and the ground or among clouds.

Tall towers are frequent targets of lightning strikes, because there is less air to act as an insulator between the tower and a cloud.  In this case, it is the Hillbrow Telkom Tower in Johannesburg, South Africa.

Lightning arcs from the top of a cloud to the horizon off the coast of the Bahamas. Lightning that comes from the top of the cloud can be positive lightning, which is rare but can be significantly more powerful than more common negative lightning. It can also strike farther from the cloud, up to 10 miles (16 kilometers) away.
