Various graphs compare details like the temperatures on the planets or how many light-years across neighboring galaxies are. VERDICT These titles may duplicate current holdings, but the series covers current knowledge and efforts that are planned for the future. Libraries looking to update or add depth to their collections will want to consider."
"Explore Earth's "local group" of galaxies with this title in the Deep Space Discovery series (6 titles). The book alternates between general information about galaxies and specific details about the Milky Way and several other nearby galaxies. Although the information is basic, the galactic scale is mesmerizing. The images, many from NASA telescopes, help inspire readers with an even greater sense of wonder. The material, though presented simply, is dramatic enough to interest readers of a variety of ages, including adults. The publisher suggests that it is for grades four through six, but the length and simplicity of the text suggest that it is at least as well suited to proficient readers in younger grades. Readers with any interest at all in space will find much enjoyment—and much to learn—here."
