    The superbubble Henize 70, also known as N70 or DEM301, in the Large Magellanic Cloud [1]. In astronomy a superbubble or supershell is a cavity which is hundreds of light years across and is populated with hot (10 6 K) gas atoms, less dense than the surrounding interstellar medium, blown against that medium and carved out by multiple supernovae and stellar winds.

  7. Mushroom cloud - Wikipedia

    en.wikipedia.org/wiki/Mushroom_cloud

    A detonation significantly below ground level or deep below the water (for instance, a nuclear depth charge) does not produce a mushroom cloud, as the explosion causes the vaporization of a huge amount of earth or water, creating a bubble which then collapses in on itself; in the case of a less deep underground explosion, this produces a ...

  8. Implosion (mechanical process) - Wikipedia

    en.wikipedia.org/wiki/Implosion_(mechanical_process)

    In an implosion-type nuclear weapon design, a sphere of plutonium, uranium, or other fissile material is imploded by a spherical arrangement of explosive charges. This decreases the material's volume and thus increases its density by a factor of two to three, causing it to reach critical mass and create a nuclear explosion.
