The Sky is Not the Limit, by astrophysicist Neil deGrasse Tyson.

The universe is awesome — bigger, older, hotter, colder, quieter, emptier and more violent than we can comprehend. Yet so few people take any interest in the cosmos. As Dr. Tyson puts it, so few of us ever “just look up.”

This book puts the universe in its proper place — the most thrilling and awe-inspiring subject of all time.
