Toddlers and preschoolers get a lovely lesson on space in this engaging board book. Through beautiful pages a mix of full-bleed photos and digital illustrations tots tour the solar system and even the Milky Way, zooming in on Earth, the Sun, moon, stars, and spacecraft. While the text is simple and age-appropriate, it clearly introduces scientific concepts: The sun warms Earth and gives it light. The concluding spread features six reader challenges that invite little ones to interact with its illustrations by touching the planets, clapping when they spot the sun, singing twinkle, twinkle at stars, and more. Kids will be starstruck.--Julia Smith Copyright 2019 Booklist
