Astronomer Vera Rubin changed the way we think of the universe by showing that galaxies are mostly dark matter.
It was their first successful night determining how fast the galaxy's stars rotate around its center (what astronomers call the rotation curve).
The Andromeda Galaxy became the first of many galaxies with unexplainable rotation curves, which Rubin observed with Ford.
Inspired by Rubin, Caputo has spent most of her career trying to detect dark matter.
Rubin continued her research unveiling the presence of dark matter in during the remainder of her career.
