Geoff Chester – Navy Observatory PAO
In this episode:
We meet Geoff Chester, the Public Affairs Officer (PAO) for the United States Naval Observatory in Washington, D.C., a position he has held since 1997. Prior to joining the Observatory Geoff worked for the Smithsonian Institution's Albert Einstein Planetarium in positions that ranged from Special Effects Technician to Staff Astronomer.
Chester shares with us the history and work done by the Naval Observatory in Washington, D.C., as well explaining to listeners how and why we keep time and what a clock really is. This information is used along with physics to determine where a celestial object is located and provides us a map of the stars.
