Supernova
Supernova is the biggest explosion of a star in a galaxy that marks the end of the star's history. Each blast of supernova is the extremely bright, super-powerful explosion of a star. Stars that experience supernova will look very bright. The brightness can reach hundreds of millions of times the star's original light. A few weeks before a star experiences a supernova, the star will release energy that equivalent with the sun's energy released during it's lifetime. This explosion of supernova collapses most star material with a speed of 30.000 km/s (10% the speed of light) and releases shock waves that can destroy the interstellar medium. Supernova can caused by the "last hurrah" of a dying massive star or when two stars orbit one another and of those star is an Earth-sized white dwarf. Because of that causes factor, supernova divided into two types. 1. Supernova Type 1 This type of supernova can happen if a star at least five times the mas
