Stars

stars are made of gas and plasma that come from a nova the nova causes a disk then gravity crushes the dust to make a star. Stars are extremely hot. The surface of the sun is 10,000 degrees Fahrenheit and 27,000,000 degrees in the core but some stars are even hotter. Are sun is a medium type star there are white dwarfs, black dwarfs, blue giants, red giants blue super-giants, red super-giants, and red and blue hyper-giants
an example of a hyper giant is VY Canis Majoris, its the biggest star ever discovered before. Are sun is made of hydrogen, and helium gasses. The bigger the star the faster it dies, and the most destructive. Are star is to small for a major death. some stars when they die cause supernovas. Supernovas are caused when a star starts running out of hydrogen when the stars out of hydrogen it starts fusing helium witch makes iron the iron kills the star, the iron attracts more and more helium, causing the star to collapse
then the collapsed core explodes into a supernova. or if the stars big enough it could collapse to the point were it bends gravity causing a black hole. If a supernova exploded 3 or 4 light years away earth would be toast . Most stars only have one star per solar system but they recently discovered many double star solar systems with one star orbiting the other stars are unique and they light up the universe.
