If readers haven’t already heard of Hélène Courtois and her marvelous contributions to astrophysics, this picture book biography illuminates her amazing life. This picture book, through mit Kids Press, starts at Courtois’ early years mapping her French countryside and onto her experiences being a woman in the sciences. Allie Summers writes a compelling tale of how she discovers Laniakea in 2013, a special supercluster of galaxies that includes our Milky Way.

This is a great contribution to any picture book biography section. The graphic design illustrations are bright and eye-catching and the writing is full of new science terms for kids to learn in tandem with Courtois’ life story. End papers include her Timeline, a Glossary of Galactic Terms, “Other Fiercely Intelligent Women in Astronomy,” and a guide to putting your telescope in the right location. Recommended for Ages 5-9.
