Opis

Stellar evolution - the birth, development and death of stars - is central to our current understanding of astronomy. This area of astrophysics is often portrayed as being difficult and mathematical, but Mike Inglis brings it to life in a unique way, combining a step-by-step introduction with suggestions for making practical observations of stars at different stages in their evolution. Every amateur astronomer - regardless of their current level of knowledge - will find this book fascinating and informative.
