Astrophysics for People in a Hurry is a book from 2017 written by Neil deGrasse Tyson. The book explains some of the "big" concepts in astrophysics and astronomy without the mathematical detail and equations that you would find in a textbook. If you have some background in any of the sciences, but specifically astronomy and physics, the book will be easier to understand. It is basically a book on theoretical astrophysics, explaining the theory behind things like the big bang, dark matter, and dark energy without the math. Tyson also explains how we have been detecting planets around other stars, and why any technologically advanced alien civilization would have a hard time finding Earth and determining that a technologically advanced civilization exists on it if they are using the same methods of planet detection we are.
The book is relatively short, around 200 pages, at least if you compare it to any college-level textbook. I found it to be a pretty quick and easy read, but to be fair, I have dozens of books on astronomy that I have been reading since I was a pre-teen, and I have a degree in electrical engineering, so the subject matter did not bog me down or go over my head. The book is rigorous enough that it may be hard to follow if you do not have at least a familiarity with astronomy. I do not think you need that level of education and experience with the subject in order to understand and enjoy the book, but it will definitely be an easier read for some people and harder for others.
