The Portland Observatory is the only remaining historic maritime signal station in the United States. As an intact survivor from the Golden Age of Sail, the Observatory was added to the National Register of Historic Places in 1972, became a National Historic Landmark in 2006, and named a National Civil Engineering Landmark in 2006. The tower was saved and reopened in 2000. The City of Portland and concerned citizens collaborated with Greater Portland Landmarks to once again restore the Observatory. In 1984 Greater Portland Landmarks assumed management of the tower, opening it for regular tours. Then, ten years later, inspections revealed serious moisture damage and an infestation of powder-post beetles. Restorations were done and the tower opened to tourists in 1939. The Observatory fell into disrepair and was donated to the City of Portland. This signal tower communication greatly increased the efficiency of Portland Harbor and the Observatory remained a working marine signal tower run by the Moody family until 1923 when the invention of the two-way radio made it obsolete. Moody informed subscribing merchants by hoisting signal flags identifying their vessels. With his powerful telescope at the top of the tower, sea captain-turned-entrepreneur Moody could identify incoming vessels as far away as 30 miles. It was a commercial venture designed to give a competitive edge to ship owners who paid Moody a subscription fee of $5.00 a year to alert them when their ships were arriving.Īt the time, ships entering the harbor could not be seen from the docks of Portland until they rounded the point of land at Spring Point Ledge and were almost in the harbor. We cultivate excellence, deliver value, enhance education, and engage the public.In 1807 Captain Lemuel Moody (1768-1846), ordered construction of this octagonal, 86-foot high tower on Munjoy Hill to serve as a communication station for Portland’s bustling harbor. easier to make a large, near-perfect mirror than to make a large, near-perfect lens.
The National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 "to promote the progress of science to advance the national health, prosperity, and welfare to secure the national defense."ĪUI collaborates with the scientific community and research sponsors to plan, build, and operate cutting-edge facilities. Telescopes use mirrors and lenses to help us see faraway objects. The observatory is open to the public and MAS members at. NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media. The Onan Observatory houses more than a dozen telescopes on four observing platforms. Observing time on NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Operated under cooperative agreement by Associated Universities, Inc.įounded in 1956, the NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. Our product line includes wicker, aluminum, cast aluminum and resin. The National Radio Astronomy Observatory is a facility of the National Science Foundation Telescope Casual has been producing quality, outdoor patio furniture for over a century.
