Supernova

A supernova is a huge stellar explosion which releases quick bursts of radiation that often briefly outshines a whole entire galaxy and has more power than the whole entire Sun could emit. This was first discovered 185 AD by chinese observers in China.The plural is ' supernoave'. During the explosion the matter inside gets blasted outside and the remains of the star is formed into a nuetron star. It only happens to stars 10 times the mass of the sun, though.

Supernovas emit radiation and their explosions give an indication to scientists and astronomers that the universe may still be expanding.

This is another pic of 1572 supernova. Huams can't live on supernovae because of high temperatures, no water, poisonous gases, etc.

The supernova after the stellar explosion then fades away for the next month or so. The speed of the explosion is quite remarkalbe as it is one tenth of the speed of light. It then drives a shockwave which picks up dust and gas along the way, which is called " supernova remnant." An example is shown below in the picture.



Several kinds of supernovae existand and they may be triggered in one of two ways that is through the way of turning off or pushing on and making more production of energy because of nuclear fusion.

Scientists are still working out why the nuclear fusion plays such a crictial part in a supernova life.

Not only the previous reasons why people cannot live on supernovae, but a supernovae is an explosion. You cannot possibly live **on an explosion!** This can be compared to the elimination of human life on a nuclear bomb area.
