The Unknown Universe: A New Exploration of Time, Space, and Modern Cosmology by Stuart Clark

3.0

This is an interesting, brief history of the major events and figures in the fields of astronomy and astrophysics, but there's actually very little about what remains unknown; most of the same information is covered in Richard Holmes' Age of Wonder and the recent version of Cosmos on television with Neil DeGrasse Tyson, so if you're familiar with those there isn't much here to learn; only the last third of the book covers recent discoveries in more depth. (Conversely, if you're not familiar with those works, this is a great primer.)
