Astrophysics For People In A Hurry - Neil DeGrasse Tyson

This was a pretty quick audiobook - at 4 hours, maybe one of the shortest I've listened to in awhile.

Tyson discusses the composition of the universe in micro and macro levels, from the molecular level, all the way to the expansion of the universe.  He talks about how scientists study these things, in mostly an informative way, but he opines a little about the scientific process and challenging the things we accept as true.  He cites great scientists like Newton, Einstein and Kepler, and talks about the spherical manner of most astrophysical phenomena, and the scale of the universe.  He talks about energy and the light spectrum, and the elements in the periodic table.

It's a good primer for astrophysics, complex enough to teach you something, yet simple enough to keep you engaged.
