Observatories still play a major role in deep space exploration

Though they are still grounded on earth, the observatories that stay looking at the sky are vital to exploring space and finding every nook and cranny in the universe. One of them, Carnegie Observatories does just that from its world famous Las Campanas Observatory in Chile. I recently got to speak with Dr. John Mulcahaey, who is director and chair of the observatories, about the work they all do.
