About Introduction To The Cosmos

Welcome to the companion website for the free book Introduction To The Cosmos!

I also intended this book to be for someone that’s interested in expanding their knowledge based on practical advice and someone that has a willingness to experiment.

This book is now completely Free! Just enter your email address for a link to download the book right away. Download the book free here!

This book is for someone that’s interested in astronomy at the beginner to intermediate level. You have an interest in the things you see in the sky at night but might not have a lot of background information and you want a place to start and have a good foundation to build upon.
