EXPLORING THE UNIVERSE

A Complete Guide to the Cosmos

by Isabel Thomas ; illustrated by Sara Gillingham

Pub Date: Nov. 12th, 2025
ISBN: 9781837290635
Publisher: Phaidon

An illustrated guide that explores the science of “what we know about the universe beyond Earth’s surface, and how we know it” from the creators of Exploring the Elements (2020) and Full of Life (2022).

The book opens with an introduction that encourages readers to explore its contents however they wish rather than feeling constrained to read in order from beginning to end. Science writer Thomas divides the information into six sections: “Earth,” “Near-Earth Space, “Our Solar System,” “Stars,” “Galaxies,” and “The Universe.” Readers can tighten their Kuiper Belt and head through the Oort cloud to explore the thoughtfully laid-out topics, each covering a two-page spread. The clear writing is dense with information. Factoids about subjects such as tardigrades and exploding meteors will reel in younger readers, while information about topics like the cosmic web and measuring gravitational waves speak to a more sophisticated audience. The stylized font used for many headers can be difficult to decipher. Timelines, key facts, and text boxes accompany the entries, with succinct explanations arranged in colorful squares. Catchy subheadings (“Are We There Yet?,” “What Is It Made Of?”) and Gillingham’s generous use of color and gradient shading against black backgrounds keep the look lively and the information flow organized. The plentiful illustrations use saturated colors and crisply rendered geometric forms to support concepts, present diagrams, and portray space scientists from around the world.

Brightly presented and packed with facts.
