Galaxy Quenching

This week: the story of astrophysicist Charity Woodrum. Charity is an extragalactic astronomer who studies the life and death of galaxies, why some galaxies burn bright and others dim and sputter out. And in the midst of an unthinkable grief in her personal life, she discovers something in the sky – a new kind of light that would guide her path forward. Special thanks to Megan Stielstra, Jad Abumrad, Michael Woodrum, Gina Vivona, and Clair Reilly-Roe.
