Information about Supernova
A supernova is very beautiful and I am not talking about the super hero. A supernova happens where there is a change in the core of a star. A change can occur in two different ways, with both resulting in a supernova. 1. A dwarf star start stealing mass from it companion star, but later the dwarf star steals to much matter and the dwarf star colapses and explodes. 2. A star's life is about to end, and the star ran out of nuclear fuel. Some of the stars mass goes into the core, the core is so heavy that it colapses and explodes. ( The sun does not have enough mass to become a supernova when its life has ended.) [Picture below shows how a dwarf star steals mass from its companion]

After the star collapses the explosion sends out all kinds of rays, like gamma rays. It shows a a wonderful display of colors all mixed up together. There is a downside, during that blast a piece of the star went out somewhere, then a blackhole formed. A blackhole is a very big vacuum that can swallow up worlds, if you want to know more about blackholes go to this link below

The picture in the middle shows a blackhole that is going to devour a planet.i.ytimg.com/vi/VDL2jTbWU0U/maxresdefault.jpg
Information about Hypernova
A hypernova (sometimes called a collapsar) is the the much more powerful version of a supernova, it is more energetic. In a supernova, a star shears off its outer matter but leaves a new star at its centre, often a neutron star. In a hypernova, the force of the explosion tears the inner star apart too. Hypernovas occur in stars with a mass greater than 30 times that of our Sun. Like in a supernova, as the star runs out of fuel it can no longer support itself under its own gravity. It collapses and explodes, sending out matter in all directions. This releases more energy in seconds than our Sun will in its entire 10 billion-year lifetime. When there is a hypernova it creates a blackhole that has two energetic jets, and it is surounded by a accretion disc.imagine.gsfc.nasa.gov/news/20may99.html

Both of them are very beautiful but also very deadly, if there is a supernova or a hypernova close by it will rip apart Earth's Magnetic field. The Magnetic field is what keeps us alive, it protects us from the deadly rays of the sun.
