It is the elements heavier than iron that are formed in a supernova. All the heavier elements up through uranium appear when a star of sufficient mass collapses in a supernova event. These heavier elements, sometimes referred to as the trans-iron elements, appear in the collapse of a massive star. In this catastrophic event, the iron and silicon (and any other lighter elements) in the star are super compressed. The already hot conditions are made even hotter, and the available energy is sufficient to drive the fusion reactions that create the trans-iron elements.
All the fusion reactions up through those that create iron are exothermic, and that means they release energy. The fusion reactions that create the trans-iron elements are endothermic, and that means energy has to be put into them. Only in the collapse of a star of sufficient mass is there enough energy to drive the fusion reactions that produce the trans-iron elements.

They are usually first formed in supernova explosions. These would be dispersed in space and might end up in a planetary system..The heavier, radioactive, nuclei would then form their daughter elements.
A supernova, or in the case of a smaller star, a nova.
yes, nothing can be overweight in the universe....... even super nova! when supernova becomes very very heavy then it explodes, hence the vacuum formed inside becomes the birth of black hole. Nikhil Swami nikhilswami1@gmail.com
When the Universe was created in the moment of the big bang, only simple molecules like helium and hydrogen were formed. These gasses later formed stars which created other elements up to iron, but no heavier.Heavier elements can not be formed by nuclear fusion in stars, and are not believed to be formed during the Big Bag. It is theorized that these elements can only be formed when massive stars explode at the end of their life cycle (in a supernova explosion).Therefore, the presence of gold itself means that a supernova exploded and formed the metals.
A star is made up of Hydrogen and Helium, (the Helium coming from the fusion of Hydrogen atoms). When a star goes super nova, it is so hot that it fuses together gases so rapidly that it creates all of the elements on the periodic table.
The Orion Nebula was not formed from a single supernova or nova event. It is a stellar nursery where new stars are currently being formed. The nebula is created by the glowing gas and dust illuminated by newly formed stars within it.
A supernova is when a massive star explodes. A neutron star is what can be formed after a supernova explosion. See related questions
Elements heavier than iron are formed in super-nova explosions.
super nova
Nuclear fusion stops and the star is no longer capable of transformming LIGHTER elements into HEAVIER. elements. At this point GRAVITY looses out and PRESSURE wins out thereby causing the supernova explosion. But bear in mind, there is a HUGE difference between an ordinary star going NOVA and a SUPERNOVA.

Supernova
Yes, they do. This is called a nova or supernova, depending on its mass. The supernova outshines every star you can see usually depending on the distance. If a star is big enough, the supernova can create a black hole in space. The crab nebula was formed by a supernovas about 1,000 years ago.
A nova or a supernova
A super nova isn't a person. A super-nova is a high mass star's explosion.
A supernova, or in the case of a smaller star, a nova.
When a star explodes, it releases an immense amount of energy, creating a supernova. This explosion can outshine an entire galaxy for a short period of time. Supernovae are crucial for the formation of heavy elements and can also cause the star to collapse and form a black hole or neutron star.
