Demographics of Antarctica
Antarctica has few permanent residents, and contains research stations and field camps that are staffed seasonally or year-round, and former whaling settlements. The largest station, McMurdo Station, has a summer population of about 1,000 people and a winter population of about 200. Approximately 29 nations, all signatory to the Antarctic Treaty, send personnel to perform seasonal (summer) or year-round research on the continent and in its surrounding oceans.
Bradley Observatory
The Bradley Observatory is an astronomical observatory owned and operated by Agnes Scott College. It is located in Decatur, Georgia, east of Atlanta, Georgia, (USA). The observatory's largest telescope, the Beck Telescope, is a vintage 30 inch (750 mm) Cassegrain reflector built in 1930. The telescope was owned and operated by an amateur astronomer, Mr. Gibson. He offered the telescope for sale, seeking to upgrade his own telescope. Agnes Scott purchased it in 1947 for about $15,000. For many years, the Beck telescope was the largest in the Southeast United States, until the Fernbank Observatory opened in 1972 with its telescope.
The observatory was built in order to house the Beck telescope and was dedicated in 1950. It also houses faculty offices and a planetarium. The observatory is a contributing structure within the National Register South Candler Street-Agnes Scott College Historic District. Dr. Chris DePree is the current director of the Bradley Observatory.
