Exactly as the title implies, this collection of essays is a breezy overview of the major topics of astrophysics for a general audience. If you have watched Tyson's update of the science television series Cosmos, then a lot of this will be familiar territory. Tyson's fascinations with particle physics, astronomy, and the deep history of life on Earth are covered here. His almost evangelical love of science is on display as well. I highly recommend the chapter on dark matter which provides a very clear explanation of a very murky topic.
