Discovery of compact HII regions (1961).First unambiguous discovery of a radio recombination line (1965).The scientific discoveries which have, and are, taking place in Green Bank are too many to number. Byrd Green Bank Telescope, a fully steerable telescope which operate from 0.2 GHz through 116 GHz and is the premiere telescope operating across those wavelengths. Over the past 60 years a number of new telescopes have been built at the site, including the 100-m Robert C. An additional number of test instruments had also been built, including Little Big Horn, and calibration instrument built down the side of a hill. Over the course of the next 10 years a total of five telescopes were place on site, ranging in size from the 40ft to 300ft in diameter. Within one year the first telescope on site was completed, the 85 ft Tatel Telescope. On Octothe groundbreaking and dedication of the Green Bank site took place. Planning Document for the Establishment and Operation of a Radio Astronomy Observatory, 1. an observatory available to all qualified scientists is an obvious solution for the problem of inadequate research facilities. The cost of such equipment places it beyond the likely means of a single institution. If the United States is to keep abreast of developments in radio astronomy, our scientists must have at their disposal larger and more powerful research equipment than is now available to them… here are no instruments in this country comparable with the large steerable paraboloid under construction in England, nor with the large interferometer arrays available in Australia and England. The impetus for the National Radio Astronomy Observatory was described in AUI’s 1956 proposal, Plan for a Radio Astronomy Observatory: This would be not only the first national astronomy observatory, but also the first national laboratory open to all scientists from around the world. Saving Earth Britannica Presents Earth’s To-Do List for the 21st Century.In 1954 a meeting was held in Washington, DC to discuss the possibility of establishing a new national center for radio astronomy within the United States, and by 1956 Associated Universities, Inc (AUI) was contracted by the National Science Foundation to begin the construction of the new National Radio Astronomy Observatory in Green Bank West Virginia.100 Women Britannica celebrates the centennial of the Nineteenth Amendment, highlighting suffragists and history-making politicians.COVID-19 Portal While this global health crisis continues to evolve, it can be useful to look to past pandemics to better understand how to respond today.Student Portal Britannica is the ultimate student resource for key school subjects like history, government, literature, and more.This Time in History In these videos, find out what happened this month (or any month!) in history.#WTFact Videos In #WTFact Britannica shares some of the most bizarre facts we can find.Demystified Videos In Demystified, Britannica has all the answers to your burning questions.
