 | 1972 | American astronomer Harlow Shapley dies. As a research student, Shapley worked under Henry Norris Russell at Princeton on the study of eclipsing binary stars. He later studied the distribution of globular star clusters and armed with that data determined the size and shape of our galaxy, and the direction to its center. He also discovered the Sculptor and Fornax dwarf galaxies. |
