Abstract

Supernovas were described and explained in this chapter. The types and subtypes of supernovas were noted. Supernovas cause a tremendous explosion at the moment they are created. The quantitative significance of supernovas was discussed. Supernovas produce particles and radiation, and create excessive temperatures. Supernovas were exemplified, and the concept of SNRs (supernova remnant) was introduced. It was observed that supernovas cause blast and shock waves, gamma ray fireballs and the vaporization of space objects. The concept of pair-instability supernovas was discussed. Pulsars are created by supernovas, it was suggested.
