mushroom cloud

Nuclear explosion's signature

A mushroom cloud is the distinctive pillar-and-cap formation produced by a massive explosion, especially a nuclear detonation.

The shape results from rapidly rising hot gases that spread outward when they hit cooler air above.

The term has become synonymous with nuclear warfare and its apocalyptic potential: The mushroom cloud rose over Hiroshima.
