Amateur astronomy is a hobby where participants enjoy observing or imaging celestial objects in the sky using the unaided eye, binoculars, or telescopes. Even though scientific research may not be their primary goal, some amateur astronomers make contributions in doing citizen science, such as by monitoring variable stars, double stars, sunspots, or occultations of stars by the Moon or asteroids, or by discovering transient astronomical events, such as comets, galactic novae or supernovae in other galaxies.
KStars is a free and open-source planetarium program built using the KDE Frameworks. It is available for Linux, BSD, macOS, and Microsoft Windows. A light version of KStars is available for Android devices. It provides an accurate graphical representation of the night sky, from any location on Earth, at any date and time. The display includes up to 100 million stars, 13,000 deep sky objects, constellations from different cultures, all 8 planets, the Sun and Moon, and thousands of comets, asteroids, satellites, and supernovae. It has features to appeal to users of all levels, from informative hypertext articles about astronomy, to robust control of telescopes and CCD cameras, and logging of observations of specific objects.
The Space Telescope Science Institute (STScI) is the science operations center for the Hubble Space Telescope (HST), science operations and mission operations center for the James Webb Space Telescope (JWST), and science operations center for the Nancy Grace Roman Space Telescope. STScI was established in 1981 as a community-based science center that is operated for NASA by the Association of Universities for Research in Astronomy (AURA). STScI's offices are located on the Johns Hopkins University Homewood Campus and in the Rotunda building in Baltimore, Maryland.
The Adler Planetarium is a public museum in Chicago, Illinois, dedicated to astronomy and astrophysics. It was founded in 1930 by local businessman Max Adler. Located on the northeastern tip of Northerly Island on Lake Michigan, the Adler Planetarium was the first planetarium in the United States. It is part of Chicago's Museum Campus, which includes the John G. Shedd Aquarium and The Field Museum. The Planetarium's mission is to inspire exploration and understanding of the universe.
Sky & Telescope (S&T) is a monthly magazine covering all aspects of amateur and professional astronomy, including what to see in the sky tonight and new findings in astronomy. Other topics we cover:
Stardome Observatory & Planetarium is a public astronomical observatory and planetarium situated in Maungakiekie/One Tree Hill Domain in Auckland, New Zealand.
Robert Burnham Jr. was an American astronomer, best known for writing the classic three-volume Burnham's Celestial Handbook. He discovered numerous asteroids, including the Mars crossing asteroid 3397 Leyla, and six comets.
A deep-sky object (DSO) is any astronomical object that is not an individual star or Solar System object. The classification is used for the most part by amateur astronomers to denote visually observed faint naked eye and telescopic objects such as star clusters, nebulae and galaxies. This distinction is practical and technical, implying a variety of instruments and techniques appropriate to observation, and does not distinguish the nature of the object itself.
A robotic telescope is an astronomical telescope and detector system that makes observations without the intervention of a human. In astronomical disciplines, a telescope qualifies as robotic if it makes those observations without being operated by a human, even if a human has to initiate the observations at the beginning of the night or end them in the morning. It may have software agents using artificial intelligence that assist in various ways such as automatic scheduling. A robotic telescope is distinct from a remote telescope, though an instrument can be both robotic and remote.
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.
Rainwater Observatory and Planetarium is an educational astronomical observatory and Planetarium run as an educational ministry of French Camp Academy. It is located near French Camp, Mississippi, United States. It is the largest observatory in Mississippi with 16+ telescopes, with the largest instruments including a 32-inch Dobsonian telescope and 14-inch Celestron catadioptric telescope. Rainwater is currently awaiting delivery of the Sollee Telescope, a 25-inch research-grade telescope. When installed in the two-story observatory building already constructed in the observatory complex, the Sollee Telescope will be suitable for serious astronomical studies, in the last remaining "dark spot" in Mississippi on the U.S. Dark Skies photograph.
Orion Telescopes & Binoculars was an American retail company that sold telescopes, binoculars and accessories online and in-store for astronomy and birdwatching. It was founded in 1975 and had corporate offices in Watsonville, California. A large proportion of its products were manufactured by the Chinese company Synta for the Orion brand name. Orion Telescopes & Binoculars shipped its products to the United States and over 20 other countries. Orion put out a semi-quarterly mail-order catalog as well as email catalogs. The company was a prominent advertiser in North American astronomy magazines, such as Sky & Telescope and Astronomy.
In amateur astronomy, "GoTo" refers to a type of telescope mount and related software that can automatically point a telescope at astronomical objects that the user selects. Both axes of a GoTo mount are driven by a motor and controlled by a computer. It may be either a microprocessor-based integrated controller or an external personal computer. This differs from the single-axis semi-automated tracking of a traditional clock-drive equatorial mount.
The Bortle dark-sky scale is a nine-level numeric scale that measures the night sky's brightness of a particular location. It quantifies the astronomical observability of celestial objects and the interference caused by light pollution. Amateur astronomer John E. Bortle created the scale and published it in the February 2001 edition of Sky & Telescope magazine to help skywatchers evaluate the darkness of an observing site, and secondarily, to compare the darkness of observing sites.
Celestial cartography, uranography, astrography or star cartography is the aspect of astronomy and branch of cartography concerned with mapping stars, galaxies, and other astronomical objects on the celestial sphere. Measuring the position and light of charted objects requires a variety of instruments and techniques. These techniques have developed from angle measurements with quadrants and the unaided eye, through sextants combined with lenses for light magnification, up to current methods which include computer-automated space telescopes. Uranographers have historically produced planetary position tables, star tables, and star maps for use by both amateur and professional astronomers. More recently, computerized star maps have been compiled, and automated positioning of telescopes uses databases of stars and of other astronomical objects.
David John Eicher is an American editor, writer, and popularizer of astronomy and space. He has been editor-in-chief of Astronomy magazine since 2002. He is author, coauthor, or editor of 23 books on science and American history and is known for having founded a magazine on astronomical observing, Deep Sky Monthly, when he was a 15-year-old high school student.
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.
