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.
Palomar Observatory is an astronomical research observatory in San Diego County, California, United States, in the Palomar Mountain Range. It is owned and operated by the California Institute of Technology (Caltech). Research time at the observatory is granted to Caltech and its research partners, which include the Jet Propulsion Laboratory (JPL), Yale University, and the National Astronomical Observatories of China.
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.
Jill Cornell Tarter is an American astronomer best known for her work on the search for extraterrestrial intelligence (SETI). Tarter is the former director of the Center for SETI Research, holding the Bernard M. Oliver Chair for SETI at the SETI Institute. In 2002, Discover magazine recognized her as one of the 50 most important women in science.
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.
Anton M.J. "Tom" Gehrels was a Dutch–American astronomer, Professor of Planetary Sciences, and Astronomer at the University of Arizona, Tucson.
Alan Hale is an American professional astronomer, who co-discovered Comet Hale–Bopp along with amateur astronomer Thomas Bopp.
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.
Donald Edward Machholz was an American amateur astronomer who was credited with the discovery of 12 comets that bear his name.
Perkins Observatory is an astronomical observatory in Delaware, Ohio. It is owned and operated by Ohio Wesleyan University.
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.
The Panoramic Survey Telescope and Rapid Response System located at Haleakala Observatory, Hawaii, US, consists of astronomical cameras, telescopes and a computing facility that is surveying the sky for moving or variable objects on a continual basis, and also producing accurate astrometry and photometry of already-detected objects. In January 2019 the second Pan-STARRS data release was announced. At 1.6 petabytes, it is the largest volume of astronomical data ever released.
William Ashley Bradfield was a New Zealand-born Australian amateur astronomer, notable as a prolific amateur discoverer of comets. He discovered 18 comets, all of which bear his name as the sole discoverer.
The Astronomical Society of New South Wales (ASNSW) is an amateur astronomy club in the state of New South Wales, Australia, founded in 1954.
The Jodcast is a bimonthly podcast created by astronomers at Jodrell Bank Centre for Astrophysics (JBCA), University of Manchester in Manchester, England. It debuted in January 2006, aiming to inspire and inform the public about astronomy and related sciences, to excite young people with the latest astronomy research results, to motivate students to pursue careers in science, and to dispel stereotypes of scientists as incomprehensible and unapproachable.
Astronomy Photographer of the Year is an annual astronomy photography competition and exhibition that is organised by the Royal Observatory, Greenwich.
The Zwicky Transient Facility is a wide-field sky astronomical survey using a new camera attached to the Samuel Oschin Telescope at the Palomar Observatory in California, United States. Commissioned in 2018, it supersedes the (Intermediate) Palomar Transient Factory (2009–2017) that used the same observatory code. It is named after the astronomer Fritz Zwicky.
The Northolt Branch Observatories is an astronomical observatory located in London, England. NBO collects follow-up astrometry of near-Earth asteroids and other small Solar System objects. It focuses on public outreach, sharing images, videos and information about asteroids on social media.
Daniel Wayne Hooper is an American cosmologist and particle physicist specializing in the areas of dark matter, cosmic rays, and neutrino astrophysics. He is a senior scientist at Fermi National Accelerator Laboratory and a professor of astronomy and astrophysics at the University of Chicago.
Tenagra Observatory and Tenagra Observatory II are astronomical observatories in Cottage Grove, Oregon and Arizona. The observatories house heavily automated robotic telescopes.
