It is not certain, but what is generally thought of as the first phase of a supernova event is gravitational collapse. The fusion reactions have exhausted fuel, and fusion is supplying less and less energy. This allow the immense gravity that has been trying to compress everything all along to begin to dominate the stellar dynamic.
A hypernova is a more powerful and larger explosion than a supernova. It occurs when a massive star collapses and releases an immense amount of energy, much greater than that of a supernova. Hypernovae are one of the most energetic events in the universe.
Nebula. Some nebulae are formed as the result of supernova explosions. The material thrown off from the supernova explosion is ionized by the supernova remnant. One of the best examples of this is the Crab Nebula, in Taurus. It is the result of a recorded supernova, SN 1054, in the year 1054 and at the centre of the nebula is a neutron star, created during the explosion.
The Vela Supernova is the remnant of a supernova explosion that occurred in the Vela constellation about 11,000 to 12,300 years ago. It is located about 800 light-years away from Earth and is one of the closest known supernova remnants to us.
The lowest energy release in a supernova is about 1.5E44 Joules, the highest energy release in a nuclear explosion (i.e. the Soviet Tsar Bomba of 1961) was about 2.17E17 joules (although significantly larger yields are possible, nobody has seen any reason to build one).This is 27 orders of magnitude between the smallest supernova and the largest nuclear explosion that was ever done!!!
One way a star might die is by going through a supernova explosion. This explosion can release massive amounts of energy and trigger the formation of a new star through the remnants left behind, such as in a supernova remnant.
After a Supernova explosion, a Black Hole is created. Thats right.... Stars make black holes! Here is the life cycle of stars! Not the real one, just... when it turns into a black hole. Gases in space> Bigger gasses in space> A pretty star> Still a normal star> Old dwarf star> SUPERNOVA EXPLOSION> Giant Black Hole! Tada!

A supernova explosion is one of the most explosive events in the universe. It occurs when a massive star reaches the end of its life cycle and collapses under its own gravity, releasing an immense amount of energy in the process. The explosion can outshine entire galaxies for a brief period.
Platinium is created within the massive explosion of a supernova. It is one of the last things to be produced when a giant star goes supernova, therefore not a lot of it can be produced in time before the star blasts itself apart.
A supernova *is* the explosion. A super nova is caused by one of a few stellar events: A) Sudden collapse of a star, which causes massive carbon fusion. B) The gradual accumulation of material by an already collapsed star until the mass is enough to compress the core of the star and start fusion of the element carbon (normal stars fuse hydrogen)
Anywhere there are massive stars. They are relatively rare events but many have been observed since records began. The first observed Supernova was in 185 in Centaurus and was almost as bright as the moon. Our closest candidate is IK Pegasi located at a distance of only 150 light years.
A star that shined green would be one that was fusing lighter elements into copper. This can happen - for a few seconds prior to the supernova explosion.
