The Royal Astronomical Society, (RAS) was established in 1820. The RAS is headquartered in London. The primary mission of RAS is to encourage and promote the study of astronomy, solar-system science, geophysics, and closely related branches of science. RAS accomplishes this mission by publishing scientific studies in journals, the award of modest grants, educational activities and makes available a superior reference library. Membership to RAS is available to anyone with an interest in the fields of endeavors promoted by RAS. Primarily members are students, geophysicists, astronomers and related professionals.
