A twilight phenomenon (seen from the Louisiana-24 Long Range Tracking Telescope site in northern Santa Barbara county) lights up the night sky over Vandenberg Air Force Base following the launch of a Minuteman III missile September 19, 2002 (Official USAF Photo by Dennis Fisher, 30th Communications Squadron) The twilight phenomenon caused by freezing unspent fuel from a Minotaur I launch at ...
A gas explosion is the ignition of a mixture of air and flammable gas, typically from a gas leak. [1] In household accidents, the principal explosive gases are those used for heating or cooking purposes such as natural gas , methane , propane , butane .
Among the largest known explosions in the universe are supernovae, which occur after the end of life of some types of stars. Solar flares are an example of common, much less energetic, explosions on the Sun, and presumably on most other stars as well. The energy source for solar flare activity comes from the tangling of magnetic field lines ...
Carbide lighting was inexpensive, but was prone to gas leaks and explosions. Early models of the automobile, car, motorbike and bicycle used carbide lamps as headlamps. Acetylene gas, derived from carbide, enabled early automobiles to drive safely at night. Thick concave mirrors combined with magnifying lenses projected the acetylene flame light.
The massive explosion at the Sandman Signature Hotel in downtown Fort Worth, suspected as a gas leak, may be part of a worsening trend across the US. Gas leak explosions are happening more often ...
Nitrogen glow Oxygen glow Electrical discharge in air Particle beam from a cyclotron. Ionized-air glow is the luminescent emission of characteristic blue–purple–violet light, often of a color called electric blue, by air subjected to an energy flux either directly or indirectly from solar radiation.
Their light curves are generally very broad and extended, occasionally also extremely luminous and referred to as a superluminous supernova. These light curves are produced by the highly efficient conversion of kinetic energy of the ejecta into electromagnetic radiation by interaction with the dense shell of material.
Argon flash, also known as argon bomb, argon flash bomb, argon candle, and argon light source, is a single-use source of very short and extremely bright flashes of light. The light is generated by a shock wave in argon or, less commonly, another noble gas. The shock wave is usually produced by an explosion. Argon flash devices are almost ...
