A Type II supernova results from the rapid collapse and violent explosion of a massive red supergiant star.
A star must have an initial mass of roughly at least 8 times (and no more than 40-50 times) the mass of the Sun for this type of explosion.
The star produces a massive core of iron by a series of nuclear fusion reactions.
Iron cannot be used to produce more energy and the core collapses under gravity. The energy released in this gravitational collapse is the cause of the explosion.
Also there is the presence of hydrogen in the composition of the spectrum. Finally, this type of supernova is seen only in the spiral arms of galaxies and in H II galaxies, but not in elliptical galaxies.
supernovae are classified by the lines in their spectra (which indicate which elements are present). type I supernovae have no hydrogen lines, having been caused by the explosion of a star with no hydrogen envelope. type II supernovae have hydrogen lines, indicating that the exploding progenitor star had retained a significant amount of its hydrogen before its supernova. type I supernovae are further classified based on the presence of silicon lines, which are present in type Ia supernovae but not types Ib and Ic.
Supernovae are classified as Type I or Type II depending upon the shape of their radioactive decay of the unstable heavy elements produced in the explosion.
Shocks from supernovae are abrupt changes in pressure and temperature caused by the explosion of a massive star. These shocks create powerful waves that propagate through the surrounding interstellar medium and can trigger the formation of new stars and influence the dynamics of gas and dust in galaxies. They also contribute to enriching the interstellar medium with heavy elements synthesized in the supernova explosion.
Type 2 supernovae occur in massive stars when the iron core reaches a critical mass because fusion of iron absorbs energy rather than releasing it. This causes a buildup of inert iron in the core, leading to a collapse due to lack of outward pressure to counteract gravity. The collapse triggers a powerful explosion, resulting in a Type 2 supernova.

All the germanium in the universe was made in supernovae explosions.
Supernovae are massive explosions that occur when a star uses up its gas and explodes so they will only occur once a star has died.
Yes given enough time

Explosions in space are often referred to as supernovae or space bursts. These phenomena can occur when stars reach the end of their life cycle and explode in a burst of energy, releasing shock waves and radiation into space.
Type 1a supernovae occur in binary star systems where one star is a white dwarf that accumulates material from its companion until it reaches a critical mass, causing a thermonuclear explosion. Type 2 supernovae happen when a massive star runs out of fuel and collapses under its own gravity, leading to a powerful explosion. The key difference is the mechanism of the explosion: type 1a is caused by thermonuclear reactions, while type 2 is due to gravitational collapse.
Virtually any atom of element more massive than oxygen(including carbon and many more elements your body consists of) was created in supernovae explosions.
"explode as supernovae". These are called Type II supernovae and sometimes a neutron star is formed, not a black hole.
Gamma rays are produced by high-energy processes such as nuclear reactions, supernovae explosions, or particle interactions. These processes release immense amounts of energy, causing some of it to be emitted in the form of gamma rays, which are the most energetic type of electromagnetic radiation.
