Supernovae

By: Sidra

A Supernova is a stellar explosion of a massive star. The explosion will take weeks, or even months before it gradually fades away out of vision. A supernova occurs when a star cannot stand the force of its own gravity. A gravitational collapse happens and surrounding hot gasses are reduced. The remaining particles are greatly condensed, and sometimes become black holes or neutron stars. Sometimes a black hole swallows up the explosion before it can be seen at all. When a supernova can be seen, its brightness may even be of 10 billion suns. In some cases, mass flows into the core by the the continued making of iron from nuclear fusion. Once the core has gained so much mass, it cannot withstand its own weight, and the core folds.

For some stars, becoming a supernova represents its last stage. However, sometimes the supernova slowly evolves a black hole or a neutron star. The star becomes so massive, it explodes into a supernova. Then, the supernova may become a black hole or a neutron star. A neutron star is a type of remnant that may be a result from a gravitational collapse of a massive star. Again, a supernova also can become a black hole, which is a region of space in which there is so much gravity, that nothing may escape from its pull.

A supernova can become either one of these, as a result of the collapse of a massive star. In a galexy like the Milky Way, a supernova normally occurs only once every fifty years. It is almost impossible to see a supernova through the naked human eye. However a supernova seems quite different through a telescope. It explosion is very, very bright.

Supernovae remnants as well as the explosions are also very colorful. Many supernovae during the explosion are red and orange, because the star is exploding. However the remnant colors vary. They can be of any color on behalf of the explosion. They can be many different colors such as green, bright orange, yellow, red, white, silver, blue, and even a hue of pink.

Supernovae are a mysterious topic still; even now scientists and astronomers are hunting endlessly to learn more about supernovae. And these exploding stars are still confusing objects of our universe.
