A fascinating look into time and space. I'm not entirely sure how up-to-date this is, since the foreword speaks about "newer findings" that have been added, but then the foreword is from 1996.

A Brief History of Time is definitely a good way to start, if you're new to the topic of astrophysics. If you have read several more recent publications, you'll most likely have heard about all the information Hawking gives here.
