The Adler Planetarium is a public museum dedicated to the study of astronomy and astrophysics. It was founded in 1930 by Chicago business leader Max Adler. It is located on the northeast tip of Northerly Island at the shore of Lake Michigan in Chicago, Illinois. The Adler was the first planetarium in the United States and is part of Chicago's Museum Campus, which includes the John G. Shedd Aquarium and The Field Museum. The Adler's mission is to inspire exploration and understanding of the universe.
John Lowry Dobson was an amateur astronomer and is best known for the Dobsonian telescope, a portable, low-cost Newtonian reflector telescope. He was also known for his efforts to promote awareness of astronomy through public lectures including his performances of "sidewalk astronomy." Dobson was also the co-founder of the amateur astronomical group, the San Francisco Sidewalk Astronomers.
A Dobsonian telescope is an altazimuth-mounted Newtonian telescope design popularized by John Dobson in 1965 and credited with vastly increasing the size of telescopes available to amateur astronomers. Dobson's telescopes featured a simplified mechanical design that was easy to manufacture from readily available components to create a large, portable, low-cost telescope. The design is optimized for observing faint, deep-sky objects such as nebulae and galaxies. This type of observation requires a large objective diameter of relatively short focal length and portability for travel to less light-polluted locations.
Robert Burnham Jr. was an American astronomer, best known for writing the classic three-volume Burnham's Celestial Handbook. He is the discoverer of numerous asteroids including the Mars crossing asteroid 3397 Leyla, as well as six comets.
The Astronomical Society of the Pacific (ASP) is an American scientific and educational organization, founded in San Francisco on February 7, 1889. Its name derives from its origins on the Pacific Coast, but today it has members all over the country and the world. It has the legal status of a nonprofit organization.
Terence Dickinson CM is a Canadian amateur astronomer and accomplished astrophotographer who lives near Yarker, Ontario, Canada. He is the author of 14 astronomy books for both adults and children. He is the editor of SkyNews magazine, which he founded in 1995. Dickinson has been an astronomy commentator for Discovery Channel Canada and taught at St. Lawrence College. He has made appearances at such places as the Ontario Science Centre. The asteroid 5272 Dickinson is named after him.
Leuschner Observatory, originally called the Students' Observatory, is an observatory jointly operated by the University of California, Berkeley and San Francisco State University. The observatory was built in 1886 on the Berkeley campus. For many years, it was directed by Armin Otto Leuschner, for whom the observatory was renamed in 1951. In 1965, it was relocated to its present home in Lafayette, California, approximately 10 miles (16 km) east of the Berkeley campus. In 2012, the physics and astronomy department of San Francisco State University became a partner.
Astronomy is a monthly American magazine about astronomy. Targeting amateur astronomers, it contains columns on sky viewing, reader-submitted astrophotographs, and articles on astronomy and astrophysics for general readers.
Sidewalk astronomy or street corner astronomy refers to the activity of setting up a telescope in an urban place on a for-profit or non-profit basis as entertainment and/or for public education.
Edwin Charles Krupp is an American astronomer, researcher, author, and popularizer of science. He is also known as Ed or E.C. He is an internationally recognized expert in the field of archaeoastronomy, the study of how ancient cultures viewed the sky and how those views affected their cultures. He has taught at the college level, as a planetarium lecturer, and in various documentary films. He has been the director of the Griffith Observatory in Los Angeles since first taking over the position in 1974 after the departure of the previous director, William J. Kaufmann III. His writings include science papers and journal articles, astronomy magazine articles, books on astronomy and archaeoastronomy for adults, and books explaining sky phenomena and astronomy to children.
Jay Myron Pasachoff is an American astronomer. Pasachoff is Field Memorial Professor of Astronomy at Williams College and the author of textbooks and tradebooks in astronomy, physics, mathematics, and other sciences.
The International Year of Astronomy (IYA2009) was a year-long celebration of astronomy that took place in 2009 to coincide with the 400th anniversary of the first recorded astronomical observations with a telescope by Galileo Galilei and the publication of Johannes Kepler's Astronomia nova in the 17th century. The Year was declared by the 62nd General Assembly of the United Nations. A global scheme, laid out by the International Astronomical Union (IAU), was also endorsed by UNESCO, the UN body responsible for educational, scientific, and cultural matters.
Colin Alistair Ronan FRAS was a British author and specialist in the history and philosophy of science.

WorldWide Telescope (WWT) is an open-source set of applications, data and cloud services, originally created by Microsoft Research but now an open source project hosted on GitHub. The .NET Foundation holds the copyright and the project is managed by the American Astronomical Society and has been supported by grants from the Moore Foundation and National Science Foundation. WWT displays astronomical, earth and planetary data allowing visual navigation through the 3-dimensional (3D) Universe. Users are able to navigate the sky by panning and zooming, or explore the 3D universe from the surface of Earth to past the Cosmic microwave background (CMB), viewing both visual imagery and scientific data about that area and the objects in it. Data is curated from hundreds of different data sources, but its open data nature allows users to explore any third party data that conforms to a WWT supported format. With the rich source of multi-spectral all-sky images it is possible to view the sky in many wavelengths of light. The software utilizes Microsoft's Visual Experience Engine technologies to function. WWT can also be used to visualize arbitrary or abstract data sets and time series data.
Chile can be considered astronomy's world capital. In 2011, Chile was home to 42% of the world's astronomical infrastructure consisting mostly of telescopes. In 2015 it expected to contain around 70% of the global infrastructure by 2020. In the Atacama desert region of northern Chile, the skies are exceptionally clear and dry for more than 300 days a year. These conditions have attracted the world's scientific community to develop in the Atacama desert the most ambitious astronomical projects in the history of mankind.
Robert Horace Baker was an astronomer.
