A small, attractive book, intended for young readers and language learners.  There are just a few sentences on each two-page spread, in large font, presented in both English and Spanish, accompanied by full-page photos or diagrams.  The information up-to-date, in line with our current understanding of space (Pluto is listed along with Ceres and Eris as dwarf planets, rather than with the other planets).  It is a useful tool for beginning readers as well as for introductory science, though the information provided is very basic.
