The Life and Death of Supernovae

Everything in the world, including stars, is dead. A supernova occurs when a star "dies". Supernova is a star explosion. These explosions emit huge amounts of energy. And it is equivalent to some nuclear warheads, or 1 million tons TNT. Supernovae emit more energy. That is the energy of our son's life. Supernovae play a major role in the Milky Way as a major source of heavy elements in the universe. In the life of big stars, they create heavy elements in the core.

Such a huge star exhausted their nuclear fuel in just a few million years, then collapsed under their own gravitation, leading to a spectacular and explosive death called supernova. This explosive death of Antares will be very bright. It will be under the broad sun on the planet, and then you can see even a half year old light year! Because it poses a threat to us, the earth is safe enough from supernovae. The Star Wright system WR 104's Wolf Layette star which is 7,500 light years away from the light will become a supernova. Wolf stars can also generate high energy gamma beams that are strictly focused from their poles. This gamma ray burst (GRB) is the most energetic phenomenon known to any stellar object.

Near supernovae are supernovae that are close enough to the Earth to make a significant impact on the Earth 's sphere. Depending on the type and energy of the supernova, it may be 3000 light years apart. Gamma rays from supernovae chemically react in the upper atmosphere and convert molecular nitrogen to nitrogen oxides. Nitrogen oxide is sufficient to expose the surface to harmful ultraviolet solar radiation. This is thought to be the cause of the Ordovician - Diatomaceous earth extinction, which caused nearly 60% of the Earth's marine life to die. The theory of 1996 suggests that traces of past supernovae may be found on the earth in the form of metal isotopes of the rock formations. Concentration of iron 60 was later reported in deep ocean rocks of the Pacific Ocean. In 2009, the nitrate ion content of the Antarctic ice layer increased and was found simultaneously with the supernovae of 1006 and 1054.
