This is a nice book if you like looking at photos.
It is organised in terms of distance from the earth, there are some photos of objects in our solar system, some of these are a bit pixellated since the objects are very small and distant. From there out it's stars, nebulae and galaxies all the way.
It's not a deeply scientific book, it doesn't aim to be, and anyone who needs real science should look elsewhere. It's much more a pretty pictures for artists type of book, and as such sometimes a bright or spectacular image seems to have been chosen ahead of a sharp one, though many of the images are sharp.
It's not huge, but it is not outrageously small for a picture book.
There are a lot of photos in it, I sort of expect they are all on the web somewhere, or very similar ones are, but it's nice to have them collected together.
