How did the element of gold form in the universe?
Gold, and all the other elements heavier than carbon, were formed by nuclear fusion in the centers of stars during supernova explosions. When a very massive star explodes in a supernova, the core of the star is crushed into a black hole, and the rest of the star is blown away out into space. Billions of years later, the dust condenses in a new planetary nebula and becomes part of a planet.
Where are the heaviest nuclei of all formed?
Elements heavier than iron are formed through the fusion reaction in stars when a supernova occurs. The lighter elements up through iron are formed in "regular" stellar fusion, and this is what powers most stars throughout their lives. A lot of energy is created in the fusion reactions, and this is why stars "burn" the way they do. But after iron, fusion switches from exothermic to endothermic. That means energy must be put into the fusion reaction to create these heavier elements, and only when a super abundance of energy is available, like during the collapse of a star in a supernova, is there sufficient energy to drive those fusion reactions. All the trans-iron elements up through uranium are created in the supernova.
These stars are produced during a supernova event?
Either a neutron star or a black hole. Note: These are not really stars but stellar remnants.
Does a star change during its life cylcle?
Yes. The possible cycle is: protostar/brown dwarf main sequence star red giant supernova/super giant white dwarf/black hole black dwarf
How many pounds of thrust does the space shuttle produce during liftoff?
3 million pounds of thrust
Did supernova explosions that occur in a star cluster happen during the first 100 million years in the life of the universe?
yes
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.
What damage did the Statue of Liberty sustain during the Black Tom explosions?
The damage was about 1.98 million dollars after the explosion.
Why are cosmic rays produced?
The origin of cosmic rays, which are actually not electromagnetic radiation but rather particles, protons and atomic nuclei - continues to be mysterious, but they are believed to be created during supernova explosions, and also likely created by active galactic nuclei.
What is explosion an example of?
different reactions during explosions
When is magnesium formed in stars?
During supernova events.
Are there records of super nova that were seen in daytime?
Up until the invention of the telescope, nearly all supernova explosions would have been observed with the naked eye.Some, if not all would have been visible during the day in some form, because of the distances involved.I'm not aware of any records being kept specifically on daytime observations. but a full list of recorded supernova can be found in the related link.

Is supernova true?
Do you mean SuperNova as in the event of the sun expanding to burn up the inner planets after it has used the last of its available fuel? Yes it is true that science believes this will happen, but realistically we have no way of knowing how or when, exactly it will happen (I.E overnight or over the period of years) Dont worry though, its not scheduled to happen for about another 5 Billion years! Besides, OUR Sun will never go supernova; only stars much larger than our sun can do that. And we've already BEEN IN one; all of the heavy elements of our planet were produced during supernova explosions early in the universe's life.
How to manage and take precautions during nuclear explosions?
dance
How do volcanoes react during an eruption?
very big explosions
Where did all the elements come from?
Hydrogen, some helium and less lithium are the result of the big bang. All the other elements are made inside the cores of stars, except for elements heavier than iron. All elements heavier than iron are created during supernova explosions.
