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.
