1. Cosmic Explosions: Seeds of Life Poonam Chandra Royal Military College of Canada

2.  Universe is 14 billion years old.  Our sun is 5 billion years.  Universe is 14 billion years old.  Our sun is 5 billion years. Supernovae and Gamma ray bursts Explosions lasting fraction of a second to few seconds. Supernovae and Gamma ray bursts Explosions lasting fraction of a second to few seconds.

3. SN & GRB: Most powerful explosions Energy is 10 29 times more than an atmospheric nuclear bomb explosion. One supernova can shine brighter than the whole galaxy consisting of 200 billion stars. As much energy in 1 month as Sun will emit in 5 billion years. Gamma ray bursts are 100 times more powerful than even supernovae.
