I actually preferred this to the Earth book that I read beforehand. Though it started with what felt like a science lesson in light and instruments, I quite enjoyed the images and information that followed.

There was all sorts of examples surrounding both natural lights, such as lightning and forest fires, to man made lights ranging from cities to fishing boats. I found it especially interesting to see comparisons of the same place over different years highlighting how areas have developed and expanded, as well as examples of how natural disasters or even Wars have instead caused the amount of light in some areas to decrease.

There is however only so much info on lights you can absorb before you start going slightly mad and I did find myself speeding through the last few sections. I feel like this is something I would prefer to have watched a video of with narration, but I’m glad I checked it out nonetheless and big thanks to NASA for making these available for free. I look forward to reading some more spacey ones next.
