For those of you with younger kids who have an interest in the cosmos, I highly recommend this book. It was written by Stephen Hawking and his daughter and the writing is aimed for an average 4th or 5th grader, I think. It is a fictional story that is easy to read (big font size) and has illustrations as well as pictures taken from the Hubble spacecraft. It presents things like black holes, supernovas, mass, exoplanets and other universe-related topics in a scientific but very kid-friendly way. Great for those kids who thirst for some deeper knowledge of these things but still prefer a "kid-format".
