Space 101

Astronomy in simple words

Since the dawn of civilization, humanity has looked up and gazed into the unknown, seeking answers to fundamental questions: Why is the sky blue? Why do stars twinkle? Where do asteroids come from? What is a black hole? When did galaxies form? What is dark matter and dark energy? How did it all begin? And how will it all end?

If you have questions, this book has answers. And if it does not have an answer, it will take you to the frontier of our ignorance, to the edge of what we know.

Our journey begins close to home, in the solar system and our neighboring planets. Then we will venture into deep space exploring stars and alien worlds. We will continue with a tour of our galaxy and take off to other galaxies and far beyond. We will learn about the Universe as a whole, taking a deep look into its mysteries. By the end, you will understand how we learned it all.

Why Space 101? This is not a university book, and you do not need a degree to understand it. It is for anyone who is curious about Astronomy and is eager to learn more. So, think of Space 101 as a starting point – a basic guide to help you understand the wonders of Astronomy.
