What is one of the first events in the explosion of the supernova?
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.
What is the name for a supernova cloud?
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.
How many times bigger is a supernova than a nuclear explosion?
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!!!

What is made after a supernova?
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!
Is a hydergen bomb explosion a supernova or a short lived star?
Compared to a supernova, a nuclear bomb would be like a puff of breath in a hurricane. Even a SMALL star is the equivalent of millions of hydrogen bombs PER SECOND, and a supernova is billions of times more powerful. However, a nuclear explosion IS like one grain of sand out of the center of a star; with a temperature of millions of degrees for a tiny fraction of a second.
Why is platinum so rare?
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.
How big does a supernova gets before it explodes?
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)
Why aren't there any greenstars?
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.
Where do supernovas explode?
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.
What are some of the unsolved mysteries of astronomy?
One of the biggest unsolved mysteries of astronomy is what happened before the Big Bang. The question of what events caused the gigantic explosion have not been explained. The matter that was always present could not remain in a stable condition and just explode all at once. One unsolved mystery of astronomy is the creation of a Type Ia Supernova.
What is the cataclysmic event called in which an exploding star produces all of the elements heavier than iron?
A supernova. It is an explosion that crushes the core of the star into a black hole or neutron star, and blasts all of the remaining mass of the star out into space. We know that our Sun is a 3rd generation star, because the Earth contains elements like iron, gold, lead, or uranium that can ONLY be produced in a supernova. And us? We're star-stuff; the iron atoms in our blood and the calcium atoms in our bones has already been through at least ONE supernova explosion.
