A mushroom cloud is a distinctive mushroom-shaped flammagenitus cloud of debris, smoke, and usually condensed water vapour resulting from a large explosion. The effect is most commonly associated with a nuclear explosion , but any sufficiently energetic detonation or deflagration will produce a similar effect.
A transient condensation cloud, also called a Wilson cloud, is observable surrounding large explosions in humid air. When a nuclear weapon or high explosive is detonated in sufficiently humid air, the "negative phase" of the shock wave causes a rarefaction of the air surrounding the explosion but not of the air contained within it.
Background radiation is largely homogeneous and isotropic. A slight detectable anisotropy is present which correlates to galaxy filaments and voids [ 2 ] [ 3 ] . The discovery (by chance in 1965) of the cosmic background radiation suggests that the early universe was dominated by a radiation field, a field of extremely high temperature and ...
The cumulonimbus flammagenitus cloud (CbFg), also known as the pyrocumulonimbus cloud, is a type of cumulonimbus cloud that forms above a source of heat, such as a wildfire, nuclear explosion, or volcanic eruption, [5] and may sometimes even extinguish the fire that formed it. [6] It is the most extreme manifestation of a flammagenitus cloud.
Flammagenitus cloud above the 2014 Oregon Gulch Fire in Oregon and California, 2014. Aircraft is an F-15C Eagle. Flammagenitus is often grayish to brown in color because of the ash and smoke associated with the fire. It also tends to expand because the ash involved in the cloud's formation increases the amount of condensation nuclei.
The explosion of Tsar Bomba, according to the classification of nuclear explosions, was an ultra-high-power low-air nuclear explosion. [citation needed] The mushroom cloud of Tsar Bomba seen from a distance of 161 km (100 mi). The crown of the cloud is 65 km (40 mi) high at the time of the picture.

Two other effects which occurred between reionization and our observations of the cosmic microwave background, and which appear to cause anisotropies, are the Sunyaev–Zeldovich effect, where a cloud of high-energy electrons scatters the radiation, transferring some of its energy to the CMB photons, and the Sachs–Wolfe effect, which causes ...
