Astronomy

"...a non-profit worldwide scientific and educational organization of amateur and professional astronomers who are interested in stars that change in brightness—variable stars."

"The American Astronomical Society (AAS) is the major organization of professional astronomers in North America. The mission of the American Astronomical Society is to enhance and share humanity's scientific understanding of the Universe."

Based in Northeastern Ohio. "The Cuyahoga Astronomical association (CAA) is a nonprofit organization established in 1957. Its purpose is to organize local amateur astronomers and to promote the science of astronomy to its members and the general public."

"The European Space Agency (ESA) is Europe's gateway to space. It's mission is to shape the development of Europe's space capability and ensure that investment in space continues to deliver benefits to the citizens of Europe and the world"

"Working tool providing all the latest detections and data announced by professional astronomers, useful to facilitate progress in exoplanetology."

"The mission of the Harvard-Smithsonian Center for Astrophysics (CfA) is to advance our knowledge and understanding of the universe through research and education in astronomy and astrophysics. "

"The Infrared Processing and Analysis Center is NASA's multi-mission center of science, data and operations expertise for long-wavelength astrophysics. IPAC carries out challenging data processing tasks essential to the science return from large astronomy programs such as all-sky surveys or Great Observatories."

"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."

"Information You Can Trust"

"The Kavli Institute for Particle Astrophysics and Cosmology, or KIPAC, was inaugurated in 2003 as an independent laboratory of Stanford University to serve as a bridge between the disciplines of astrophysics, cosmology and particle physics. KIPAC's members work in the Physics and Applied Physics Departments on the Stanford campus and at the SLAC National Accelerator Laboratory. Its mission is to bring the resources of modern computational, experimental, observational and theoretical science to bear on our understanding of the universe at large."

"...established during the Apollo missions to foster international collaboration and to serve as a repository for information gathered during the early years of the space program. "

Main website for NASA.

"The NTRS is a valuable resource for researchers, students, educators, and the public to access NASA's current and historical technical literature and engineering results. Over 500,000 aerospace-related citations, over 200,000 full-text online documents, and over 500,000 images and videos are available. "

Founded by Carl Sagan. "...the Planetary Society sponsors projects that will seed innovative space technologies, nurtures creative young minds, and is a vital advocate for our future in space."

"The Portal To The Universe provides a global portal for online astronomy content, serving as an index and aggregator. The site itself features news, blogs, video podcasts, audio podcasts, images, videos and more. Web 2.0 collaborative tools, such as the ranking of different services according to popularity, help the user to sift constructively through the wealth of information available and will promote interactions within the astronomy multimedia community."

"The SETI Institute is a non-profit corporation that serves as an institutional home for research and educational projects relating to the study of life in the universe. The Institute conducts research in a number of fields including astronomy and planetary sciences, chemical evolution, the origin of life, biological evolution, and cultural evolution."

Provided by NASA. "SkyView is a Virtual Observatory on the Net generating images of any part of the sky at wavelengths in all regimes from Radio to Gamma-Ray."

"Sloan Digital Sky Survey is the most ambitious astronomical survey ever undertaken. The survey will map one-quarter of the entire sky in detail, determining the positions and absolute brightnesses of hundreds of millions of celestial objects. It will also measure the distances to more than a million galaxies and quasars. "

A free-standing science center, located on the campus of The Johns Hopkins University and operated by the Association of Universities for Research in Astronomy (AURA) for NASA. Operates the science program for the Hubble Space Telescope and will conduct the science and mission operations for the James Webb Space Telescope and supports other astronomy programs and conducts world-class scientific research.

"StarDate is the public education and outreach arm of the University of Texas McDonald Observatory. "

"...processing and analyzing data from numerous missions to planetary bodies in our solar system, assisting in finding potential landing sites for exploration vehicles, mapping our neighboring planets and their moons, and conducting research to better understand the origins, evolutions, and geologic processes operating on these celestial bodies."

"The US Virtual Astronomical Observatory (VAO) is the VO effort based in the US, and it is one of many VO projects currently underway worldwide. The primary emphasis of the VAO is to provide new scientific research capabilities to the astronomy community."
