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 ...
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.
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 .
Explosion of unserviceable ammunition and other military items The explosion of the Castle Bravo nuclear bomb. An explosion is a rapid expansion in volume of a given amount of matter associated with an extreme outward release of energy , usually with the generation of high temperatures and release of high-pressure gases .
Massive star explosions happen about three times per century in our galaxy. Others likely happened on the other side of the galaxy. Oak Ridge lab, UT scientists seek to better understand how ...
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 ...
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.
