"The AAVSO is an international non-profit organization of variable star observers whose mission is: to observe and analyze variable stars; to collect and archive observations for worldwide access; and to forge strong collaborations and mentoring between amateurs and professionals that promote both scientific research and education on variable sources."
"The American Astronomical Society (AAS), established 1899, is the major organization of professional astronomers in North America. The basic objective of the AAS is to promote the advancement of astronomy and closely related branches of science. The membership (~6,500) also includes physicists, mathematicians, geologists, engineers and others whose research interests lie within the broad spectrum of subjects now comprising contemporary astronomy."
A non-profit scientific organization established to inform, encourage, and support the research activities of both amateur and professional astronomers who are interested in the fascinating field of Meteor Astronomy.
"The Astronomical Society of the Pacific was founded in 1889 by a group of Northern California professional and amateur astronomers after joining together to view a rare total solar eclipse. The ASP's earliest purpose was to disseminate astronomical information - a mission which has flourished with astronomers' inexhaustible exploration of the universe. The ASP has become the largest general astronomy society in the world, with members from over 70 nations."
Formed in 1890, the British Astronomical Association has an international reputation for the quality of its observational and scientific work. Membership is open to all persons interested in astronomy.
The Canadian Astronomical Society was founded in 1971 and incorporated in 1983 as a society of professional astronomers. The society is devoted to the promotion and advancement of knowledge of the universe through research and education. Membership is open to persons with a professional involvement with these goals in astronomy and the related sciences. The main activities of the Society are its annual scientific meetings, the planning and realization of scientific projects, the support of the scientific activities of its members, and the dissemination of related information among members and other interested persons. The Society supports committees on Optical and Infrared Astronomy, Radio Astronomy, Space Astronomy, Theoretical Astronomy, Education, Heritage, Canadian Grad Students, and Awards. Cassiopeia, the quarterly newsletter of the Society, is published at equinoxes and solstices.
"The purpose of the society is to contribute to and promote the advancement of astronomy, in its broadest sense, in Europe, by all suitable means and in particular: a) by providing an independent forum for the discussion of subjects of common interest; b) by providing means whereby action can be taken on those matters which appear desirable to be handled at the European level."
NRC-HIA is Canada's gateway to the stars. In addition to operating the government's observatories and a national astronomy data centre, we develop advanced scientific instruments for astronomical observatories and industrial partners — bringing out-of-this-world technology back down to Earth.
The International Astronomical Union (IAU) was founded in 1919. Its mission is to promote and safeguard the science of astronomy in all its aspects through international cooperation. Its individual members - structured in Divisions, Commissions, Working groups and Program Groups - are professional astronomers from all over the world, at the Ph.D. level and beyond, and active in professional research and education in astronomy.
The Lunar and Planetary Institute is a research institute that provides support services to NASA and the planetary science community, and conducts planetary science research under the leadership of staff scientists, visiting researchers, and postdoctoral fellows.
The Meteoritical Society is a non-profit scholarly organization founded in 1933 to promote the study of extraterrestrial materials, including meteorites and space mission returned samples, and their history.
The Planetary Society, founded in 1980 by Carl Sagan, Bruce Murray, and Louis Friedman, inspires and involves the world's public in space exploration through advocacy, projects, and education. Today, The Planetary Society is the largest and most influential public space organization group on Earth. Dedicated to exploring the solar system and seeking life beyond Earth, The Planetary Society is non-governmental and nonprofit and is funded by the support of its members.
