A ball filled with powder or other combustibles, intended to be thrown among enemies, and to injure by explosion; also, to set fire to their works and light them up, so that movements may be seen.
A large mass of fire caused by a large explosion, as of inflammable liquids or a nuclear device. The larger fireballs, as of nuclear explosions, rise seemingly intact into the air and may reach high altitudes while still glowing.
The highly luminous cloud of vaporized fission and activation products, device constituents, and surrounding support material created by a nuclear detonation.
The luminous sphere of hot gases which form a few millionths of a second after a nuclear explosion. It is the result of the absorption by the surrounding medium of the thermal X-rays emitted by the extremely hot (several tens of million degrees) weapon residues. The exterior of the fireball in air is initially sharply defined by the luminous shock front and later by the limits of the hot gases themselves.
hot gases that form a luminous sphere after a nuclear explosion
the luminous center of a nuclear explosion
a green weapon and penetrates all armor and shields
sphere of superheated, burning gas that forms immediately after a nuclear weapon is detonated.
