Star Trek: The Official Guide to Our Universe: The True Science Behind the Starship Voyages by Andrew Fazekas
My rating: 4 of 5 stars
Nice balance between science and fiction.
Fazekas does a great job interlacing material from the whole range of Trek history with a wealth of astronomy. Along the way he points out all the ways we have (or haven't) achieved Trek technology.
Even better, amid the wealth of beautiful astronomical images, there are many tutorials on how to discover the wonders of the stars, with careful instruction on how, when and where to look into the glories of the night sky.
