The scientist who discovered that the universe was expanding is Edwin Hubble. In the early 20th century, Hubble made groundbreaking observations of distant galaxies and demonstrated that they were moving away from us, a phenomenon that led to the formulation of Hubble's Law. This law states that the recessional velocity of a galaxy is proportional to its distance from Earth, meaning that the farther away a galaxy is, the faster it is moving away. This discovery provided significant evidence for the idea that the universe is not static but is actually expanding. Hubble's findings laid the foundation for modern cosmology, which fundamentally changed our understanding of the universe's structure and evolution.

Therefore, the correct answer is:
**a) Hubble**
