An biographical picture book about a female astronomer who made huge discoveries about the mysteries of the night sky and changed the way we look at the universe.

Vera Rubin was one of the astronomers who discovered and named dark matter, the thing that keeps the universe hanging together. Throughout her career she was never taken seriously as a scientist because she was one of the only female astronomers at that time, but she didn’t let that stop her. She made groundbreaking and incredibly significant discoveries that scientists have only recently been able to really appreciate—and she changed the way that we look at the universe.
