Supernova explosions happen with the most massive of stars > 20 of our Suns.

The energy output of a supernova explosion is equivalent to the energy produced by the sun over its entire lifetime.
A supernova is the catastrophic death of a star, characterized by a massive output of energy.
A supernova can produce as much energy in a few seconds as our sun will in its entire lifetime.
Elements such as gold, silver, and uranium are typically remnants of a supernova explosion. These heavy elements are formed during the intense energy release of a supernova event.
The very large nucleus of the uranium atom is a kind of energy storage unit. The energy of that nucleus is the result of the nuclear synthesis reactions that take place in a supernova. In that sense, a supernova is the energy source of uranium.
A supernova can be massive but some aren't. Every supernova is a dieing star. Supernovae are exploding stars. They represent the very final stages of evolution for some stars. Supernovae, as celestial events, are huge releases of tremendous energy, as the star ceases to exist, with about 1020 times as much energy produced in the supernova explosion as our Sun releases every second.
A supernova is not a celestial body in itself, but rather an astronomical event where a star suddenly increases greatly in brightness due to an explosive burst of energy. It is the result of the death of a massive star.
In a hypothetical fight between Superman and a supernova, the supernova would likely win due to its immense energy release and destructive power. A supernova can outshine entire galaxies and release more energy in a few seconds than the Sun will emit over its entire lifetime. While Superman possesses incredible strength and speed, he is still a being of flesh and blood, making him vulnerable to the cataclysmic forces of a supernova. Thus, in terms of raw power, the supernova's cosmic explosion would be insurmountable.
Not sure what you mean. For a few days, a supernova shines as bright as an entire galaxy - that is, roughly as bright as 100 billion stars.
During a supernova explosion, high-energy processes, such as fusion and neutron capture, occur, leading to the creation of elements heavier than iron, including carbon. These processes involve enormous amounts of energy and pressure, causing lighter elements to fuse into heavier ones. This is how carbon is produced in supernova explosions.
A safe distance from a supernova explosion would be millions of light-years away. The energy and radiation emitted during a supernova event are extremely powerful and can have destructive effects on planets and other celestial bodies nearby.
