Mount Hopkins is a 8,553-foot (2,607 m) peak of the Santa Rita Mountains range, in Santa Cruz County, southern Arizona.
The peak was named after Gilbert Hopkins, who was killed nearby during the Battle of Fort Buchanan in 1865.
It is in the Coronado National Forest and is bounded on three sides by the Mount Wrightson Wilderness.
In 1979, Russell Merle Genet founded the Fairborn Observatory, which he moved from Fairborn, Ohio to Mount Hopkins, Arizona in 1985, and worked there until 1993. He was also its first director, until 1989. Genet and his colleagues developed robotic telescopes there. It became the first totally automatic robotic observatory in the world. 
The Fred Lawrence Whipple Observatory is located on the mountain. The prime mover for the mountain's observatory was Fred Whipple, a professor at Harvard University who was in charge of a small 25 inch mirror telescope in Cambridge, Massachusetts. In Cambridge the ambient light caused light pollution that limited the telescope's usefulness.
That led to engineer Tom Hoffman being appointed by Whipple to search for a site in the U.S. that would provide a clear view of the sky at a high elevation, with minimal surrounding light pollution. After searching many locations, southern Arizona with its dry air and high elevations, and the assistance of The University of Arizona, brought Hoffman to focus on Mt Hopkins. Whipple agreed, leaving the challenge of how to transport an 8 metres (26 ft) diameter glass mirror and build a telescope on an 8,583-foot (2,616 m) mountain that had no road.

The mountain range is part of the Transverse Ranges and lies between the Los Angeles Basin and the Mojave Desert, with Interstate 5 to the west and Interstate 15 to the east. The range lies in, and is surrounded by, the Angeles and San Bernardino National Forests, with the San Andreas Fault as its northern border.
Steward Observatory is the research arm of the Department of Astronomy at the University of Arizona (UArizona). Its offices are located on the UArizona campus in Tucson, Arizona (US). Established in 1916, the first telescope and building were formally dedicated on April 23, 1923. It now operates, or is a partner in telescopes at five mountain-top locations in Arizona, one in New Mexico, one in Hawaii, and one in Chile. It has provided instruments for three different space telescopes and numerous terrestrial ones. Steward also has one of the few facilities in the world that can cast and figure the very large primary mirrors used in telescopes built in the early 21st century.
Mount Graham is a mountain in Graham County, Arizona, United States, approximately 70 miles (110 km) northeast of Tucson. The mountain reaches 10,724 feet (3,269 m) in height. It is the highest elevation in Graham County, Coronado National Forest and the Pinaleño Mountains. It is also the southernmost peak and land area in the continental United States above 10,000 feet (3,048 m). As the name "Mount Graham" is often used by locals to refer to the entire mountain range, the peak itself is frequently referred to as "High Peak". It is twentieth of the 57 ultra prominent peaks of the lower 48 states, and the first of the five in Arizona.
The Anglo-Australian Telescope (AAT) is a 3.9-metre equatorially mounted telescope operated by the Australian Astronomical Observatory and situated at the Siding Spring Observatory, Australia at an altitude of a little over 1,100 m. In 2009, the telescope was ranked as the fifth highest-impact of the world's optical telescopes. In 2001–2003, it was considered the most scientifically productive 4-metre-class optical telescope in the world based on scientific publications using data from the telescope.
The Santa Rita Mountains, located about 65 km (40 mi) southeast of Tucson, Arizona, extend 42 km (26 mi) from north to south, then trending southeast. They merge again southeastwards into the Patagonia Mountains, trending northwest by southeast. The highest point in the range, and the highest point in the Tucson area, is Mount Wrightson, with an elevation of 9,453 feet, The range contains Madera Canyon, one of the world's premier birding areas. The Smithsonian Institution's Fred Lawrence Whipple Observatory is located on Mount Hopkins. The range is one of the Madrean sky islands.
Mount Wilson is a peak in the San Gabriel Mountains, located within the San Gabriel Mountains National Monument and Angeles National Forest in Los Angeles County, California. With only minor topographical prominence the peak is not naturally noticeable from a distance, although it is easily identifiable due to the large number of antennas near its summit. It is a subsidiary peak of nearby San Gabriel Peak.
Mount Lemmon, with a summit elevation of 9,159 feet (2,792 m), is the highest point in the Santa Catalina Mountains. It is located in the Coronado National Forest north of Tucson, Arizona, United States. Mount Lemmon was named for botanist Sara Plummer Lemmon, who trekked to the top of the mountain with her husband and E. O. Stratton, a local rancher, by horse and foot in 1881. Mount Lemmon is also known as Babad Do'ag, or Frog Mountain to the Tohono O'odham. It is reported that Mount Lemmon Ski Valley, on the mountain's northeastern side, receives 200 inches (508 cm) of snow annually.
The Fred Lawrence Whipple Observatory is an American astronomical observatory owned and operated by the Smithsonian Astrophysical Observatory (SAO); it is their largest field installation outside of their main site in Cambridge, Massachusetts. It is located near Amado, Arizona on the summit, a ridge and at the foot of Mount Hopkins.
The MMT Observatory (MMTO) is an astronomical observatory on the site of Fred Lawrence Whipple Observatory. The Whipple observatory complex is located on Mount Hopkins, Arizona, US in the Santa Rita Mountains. The observatory is operated by the University of Arizona and the Smithsonian Institution, and has a visitor center in nearby Amado, Arizona. The MMTO is the home of the MMT, which has a primary mirror 6.5 m in diameter. The name comes from the six smaller mirrors originally used before the single primary mirror was installed in 1998. The primary mirror has a special lightweight honeycomb design made by the University of Arizona's Steward Observatory Mirror Laboratory. The MMT is housed in a building which allows the walls and roof around the telescope to be completely rolled back, allowing it to cool down very quickly in order to improve observation.
Mount Lemmon Observatory (MLO), also known as the Mount Lemmon Infrared Observatory, is an astronomical observatory located on Mount Lemmon in the Santa Catalina Mountains approximately 28 kilometers (17 mi) northeast of Tucson, Arizona (US). The site in the Coronado National Forest is used with special permission from the U.S. Forest Service by the University of Arizona's Steward Observatory, and contains a number of independently managed telescopes.

The Pinaleño Mountains, are a remote mountain range in southeastern Arizona, near Safford, Arizona. The mountains have over 7,000 feet (2,100 m) of vertical relief, more than any other range in the state. The mountains are surrounded by the Sonoran-Chihuahuan Desert. Subalpine forests cover the higher elevations. According to The Nature Conservancy, they traverse five ecological communities and contain "the highest diversity of habitats of any mountain range in North America." The highest point is Mount Graham at 10,720 feet (3,267 m). Locals often refer to the whole mountain range as "Mount Graham", in which case the peak is referred to as "High Peak". The mountains cover 300 square miles (780 km2) and are part of the Coronado National Forest, Safford ranger district.
Doctor Russell Merle Genet is an American astronomer, who specializes in photometric observations and probing of very short-period eclipsing binary stars.
HAT-P-3b is an extrasolar planet that orbits the star HAT-P-3 approximately 450 light-years away in the constellation of Ursa Major. It was discovered by the HATNet Project via the transit method and confirmed with Doppler spectroscopy, so both its mass and radius are known quite precisely. Based on these figures it is predicted that the planet has about 75 Earth masses' worth of heavy elements in its core, making it similar to the planet HD 149026 b.
Optics Valley is a region in southern Arizona, centered on Tucson, that is home to a high concentration of optics companies spawned by research at the University of Arizona. Based on the idea of a technology cluster such as Silicon Valley, Optics Valley is known not only for its optics industry and research but also for the astronomical observatories located in the mountains of southern Arizona where clear skies and isolated peaks make for superior observing conditions.
The MEarth Project is a United States NSF-funded, robotic observatory that is part of Fred Lawrence Whipple Observatory on Mt. Hopkins, Arizona, USA. The project monitors the brightness of thousands of red dwarf stars with the goal of finding transiting planets. As red dwarf stars are small, any transiting planet blocks a larger portion of starlight than transits around a Sun-like star would. This allows smaller planets to be detected through ground-based observations.
