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.
Clyde William Tombaugh was an American astronomer. He discovered the ninth planet Pluto in 1930, the first object to be discovered in what would later be identified as the Kuiper belt. At the time of discovery, Pluto was considered a planet, but was reclassified as a dwarf planet in 2006. Tombaugh also discovered many asteroids, and called for the serious scientific research of unidentified flying objects.
Lowell Observatory is an astronomical observatory in Flagstaff, Arizona, United States. Lowell Observatory was established in 1894, placing it among the oldest observatories in the United States, and was designated a National Historic Landmark in 1965. In 2011, the Observatory was named one of "The World's 100 Most Important Places" by Time Magazine. It was at the Lowell Observatory that the dwarf planet Pluto was discovered in 1930 by Clyde Tombaugh.
John Lowry Dobson was an American 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.
David Howard Levy is a Canadian amateur astronomer, science writer and discoverer of comets and minor planets, who co-discovered Comet Shoemaker–Levy 9 in 1993, which collided with the planet Jupiter in 1994.
The Astronomical Society of the Pacific (ASP) is an American scientific and educational organization, founded in San Francisco on February 7, 1889, immediately following the solar eclipse of January 1, 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.
The Stellafane Observatory is an astronomical observatory in Springfield, Vermont, founded in 1920 by Russell W. Porter. The Pink Clubhouse was built in 1923 at the site by the Springfield Telescope Makers Club. The name Stellafane, suggested by Porter at the club's December 1923 meeting, is derived from the Latin words stella and fanum meaning "Shrine to the Stars", and originally referred specifically to the clubhouse, but has since come to refer to all of the club's land and buildings on the summit of Breezy Hill, west of downtown Springfield.
The Oregon Star Party (OSP) was founded in 1987 and is considered one of the best annual events in the United States for observational astronomy. The Oregon Star Party takes place in the Ochoco National Forest, near the geographical center of the state of Oregon. It is far enough from population centers to provide some of the darkest skies in North America. The area's 5,000-foot (1,500 m) altitude contributes to steady seeing, which frequently provides near ideal observational conditions. The OSP site also has a treeless field of view providing an unobstructed 360 degree horizon.
An astrograph is a telescope designed for the sole purpose of astrophotography. Astrographs are mostly used in wide-field astronomical surveys of the sky and for detection of objects such as asteroids, meteors, and comets.
The Royal Astronomical Society of Canada (RASC) is a national, non-profit, charitable organization devoted to the advancement of astronomy and related sciences. At present, there are 30 local branches of the Society, called Centres, in towns and cities across the country from St. John's, Newfoundland, to Victoria, British Columbia, and as far north as Whitehorse, Yukon. There are about 5100 members from coast to coast to coast, and internationally. The membership is composed primarily of amateur astronomers and also includes numerous professional astronomers and astronomy educators. The RASC is the Canadian equivalent of the British Astronomical Association.
The Clifford W. Holmes Award is presented annually near Big Bear City, California at the RTMC Astronomy Expo to an individual for a significant contribution to popularizing astronomy.
Stephen J. Edberg is a scientist at the Jet Propulsion Laboratory. He is perhaps best known for creating collaborative efforts between amateur and professional astronomers. A professional astronomer since 1970, Edberg still considers himself to be an active amateur astronomer as well and is an active astronomical observer, photographer, and telescope maker. He presently serves as staff astronomer for the Solar System Exploration website posted by NASA Headquarters and staff scientist for Earth science communication and for Exoplanet Exploration communication.
