One of our girls loves planets, space and astronauts.  A family member gave her the “Space: The Ultimate Guide To The Universe” book a few years ago and it has been a huge hit!  It has been carried all over the house and gone on several road trips with us.  The book has pictures and information about space travel, astronomy, universe, solar system, stars and galaxies as well as posters of the universe and glow in the dark stars.  It has a lot of information packed in the variety of descriptions and colorful pictures.  The recommended age for the book is for 8 and up but if you have a child that loves space, astronauts, and planets then I would recommend it for them even at a younger age.  You’ll have to read it to a younger child but if they enjoy space as much as Karlie does then it will be a hit, not to mention educational!
