Galaxy Mapper: The Luminous Discoveries of Astrophysicist Hélène Courtois


Overview

Introducing our luminous address in the universe—and the determined woman scientist who mapped it with her team. Growing up in a small French village, Hélène Courtois had big questions about the world around her. Avidly, she observed the trails, roads, and water pathways traversing planet Earth; but her mind always wandered higher, toward the night sky. What would a map of “out there,” beyond the moon, look like? The question traveled with her to university, where curious Hélène—often the only woman in her science classes—learned to map the compositions of galaxies. Numbers swam with the stars in her brain, and after years of wonder and experimentation, Hélène and her team make a dazzling discovery—a supercluster of galaxies they name Laniakea, home to our very own Milky Way. With fascinating back matter, illustrations that shine on the page, and a lyrical text written in consultation with astrophysicist Hélène Courtois—who continues to illuminate our view of the cosmic landscape—this portrait of a contemporary female scientist will light up young minds and inspire future sky gazers and galaxy mappers to look up and dream large.

Reviews

In this appealing childhood-to-adulthood biography of Hélène Courtois, readers experience the wonders of the natural world and the cosmos. —School Library Journal Summers retraces Courtois' career and brings her ongoing tally of cosmic discoveries up to date in specific (but nontechnical) language. James poses her, often against swirling clouds of stars, looking casual, confident, and eagerly engaged, whether working alone or with students and colleagues. —Booklist James has exuberantly illustrated Courtois’ life by juxtaposing traditional classroom scenes and spot art of scientists at work, with vast night skies filled with twinkling stars and radiant blue and purple galaxies brushed with a golden glow. Sure to motivate readers to reach for the stars. —Kirkus Reviews
