Let's Discover The Stars

This is a journey that takes the reader to the world of stars, a strange world. The stars have a life-cycle that lasts hundreds of millions of years. They are born from enormous cosmic clouds in different circumstances, resulting different stars, and each star has a different life-cycle and a different degree of brightness.
The stars colours range from yellow, red and brown. Star deaths are either quiet or loud, and this is what we will learn about in this journey.
