Galaxy Mapper: The Luminous Discoveries of Astrophysicist H?l?ne Courtois

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, H?l?ne 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 H?l?ne–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, H?l?ne 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 H?l?ne 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.
