The more we learn, the more mysteries the universe holds.

Space. Humans have been fascinated by its mysteries since ancient times. From mythological stories to cutting-edge cosmology, it is filled with the history and thought of humanity. And our humble daily lives are merely fragments of this romantic universe - Earth, the solar system, galaxies, the Big Bang, the evolution of life, and the habitable zone, a space essay that talks freely about things that are usually outside of our thoughts.

[Comments from the Editor]

Everyone is attracted to the beauty of the stars and planets shining in the clear night sky, but while reading this book, I thought to myself that if human beings were not interested in that beauty more than anything else, science may not have progressed as much as it has. Please enjoy this book as you forget about your small everyday life and think about the vastness of the universe.
