Mount Stromlo Observatory located in the west of Canberra, Australia, is part of the Research School of Astronomy and Astrophysics at the Australian National University (ANU). Australia's oldest telescope and several others at the observatory were destroyed by bushfire in 2003.
The observatory was established in 1924 as The Commonwealth Solar Observatory. The Mount Stromlo site had already been used for observations in the previous decade, a small observatory being established there by Pietro Baracchi using the Oddie telescope located there in 1911. [1] The dome built to house the Oddie telescope was the first Commonwealth building constructed in the newly established Australian Capital Territory. In 1911 a delegation for an Australian Solar Observatory went to London seeking Commonwealth assistance. The League of the Empire sought subscriptions to assist raising funds. [2] Survey work to determine the site's suitability had begun as soon as the idea of a new Capital was established. By 1909 the Australian Association for the Advancement of Science was assisted in this effort by Hugh Mahon (Minister for Home Affairs). [3] Until World War II, the observatory specialised in solar and atmospheric observations. During the war the workshops contributed to the war effort by producing gun sights, and other optical equipment. After the war, the observatory shifted direction to stellar and galactic astronomy and was renamed The Commonwealth Observatory. Dr R. Wooley Director of the Observatory, worked to gain support for a larger reflector, arguing that the southern hemisphere should attempt to compete with the effectiveness of American telescopes. [4] The ANU was established in 1946 in nearby Canberra and joint staff appointments and graduate studies were almost immediately undertaken. A formal amalgamation took place in 1957, with Mount Stromlo Observatory becoming part of the Department of Astronomy [5] in the Research School of Physical Sciences at ANU, leading eventually to the formation of the Research School of Astronomy and Astrophysics in 1986. [6]
On 18 January 2003, the devastating Canberra firestorm hit Mount Stromlo (which was surrounded by a plantation pine forest), destroying five telescopes, workshops, seven homes, and the heritage-listed administration building. [7] The only telescope to escape the fires was the 1886 15-centimetre Farnham telescope. Relics from the fire are preserved in the collection of the National Museum of Australia. They include a melted telescope mirror and a piece of melted optical glass (flint). The latter has pieces of charcoal and wire fused into it from the fierce heat of the fire. [8]
Redevelopment is completed and the Observatory is now a major partner in the construction of the Giant Magellan Telescope. [9] The current observatory director is Stuart Wyithe [10]
The director's residence, destroyed in the 2003 fire, was rebuilt and opened to the public as a memorial in 2015. [11]
In 2023, the Quantum Optical Ground Station was launched. It allows for terabit-per-second communication using adaptive optics and lasers. [12]
The MACHO project detected the first instance of the gravitational lensing of one star by another, known as gravitational microlensing, in 1993 (Alcock et al. 1993; Paczynski 1996). [13] This discovery was made by repeated imaging of the Magellanic Clouds with the refurbished 50-inch Great Melbourne Telescope which was equipped with a mosaic of eight 2048 by 2048 pixel CCDs. [14] The camera was constructed by the Centre for Particle Astrophysics in California (CFPA), and at the time was the largest digital camera ever built (Frame & Faulkner 2003). Observations began in July 1992 and the project concluded in December 1999. In total, the MACHO project made over 200 billion stellar measurements, with the data processed both at the observatory and at the Lawrence Livermore National Laboratory.
Brian Schmidt organised an international collaboration, known as the High-z Supernova Search Team, to study the rate of change of the Cosmic Expansion using type Ia supernovae. In 1998, the team reach the conclusion that the cosmic expansion was accelerating, contrary to expectations. This universal acceleration implies the existence of dark energy and was named the top science breakthrough of 1998 by Science magazine. [15] In 2011, Brian P. Schmidt shared the Nobel Prize in Physics with Saul Perlmutter and Adam Riess for such observations which provided evidence for the accelerating Universe. [16]
The 2dF Galaxy Redshift Survey, co-led by Matthew Colless, undertook the largest galaxy redshift survey of its time, and was conducted at the Anglo-Australian Observatory (AAO) with the 3.9m Anglo-Australian Telescope between 1997 and 11 April 2002. [17] In total, the survey measured more than 245,000 galaxies, providing, along with the Sloan Digital Sky Survey, the definitive measurements of large scale structure in the low-redshift Universe.
The instrumentation group at Mount Stromlo Observatory has built two instruments for the Gemini Telescope. [18] This includes the near infrared integral field spectrometer, NIFS, deployed on Gemini-North, and the adaptive optics imager for Gemini-South, GSAOI. NIFS, when nearly completed, was destroyed in the bushfires of 18 January 2003, and rebuilt.
A new rapid survey telescope, SkyMapper, was completed in 2014. [19] SkyMapper resides at the ANU's other observatory (Siding Spring) and can be operated remotely from Mount Stromlo. [20]
Mount Stromlo hosts a DORIS (geodesy) earth station installed by France's CNES. [21]
Mount Stromlo Observatory is located at an altitude of 770 metres above sea level on Mount Stromlo. Situated west of the centre of Canberra, near the district of Weston Creek. Canberra's main water supply treatment plant is located nearby. [22]
The observatory received an Engineering Heritage International Marker from Engineers Australia as part of its Engineering Heritage Recognition Program. [23]
The observatory received an IEEE Special Citation from IEEE as part of its IEEE Milestone Program. [24]
The Australian Astronomical Observatory (AAO), formerly the Anglo-Australian Observatory, was an optical and near-infrared astronomy observatory with its headquarters in North Ryde in suburban Sydney, Australia. Originally funded jointly by the United Kingdom and Australian governments, it was managed wholly by Australia's Department of Industry, Innovation, Science, Research and Tertiary Education. The AAO operated the 3.9-metre Anglo-Australian Telescope (AAT) and 1.2-metre UK Schmidt Telescope (UKST) at Siding Spring Observatory, located near the town of Coonabarabran, Australia.
Siding Spring Observatory near Coonabarabran, New South Wales, Australia, part of the Research School of Astronomy & Astrophysics (RSAA) at the Australian National University (ANU), incorporates the Anglo-Australian Telescope along with a collection of other telescopes owned by the Australian National University, the University of New South Wales, and other institutions. The observatory is situated 1,165 metres (3,822 ft) above sea level in the Warrumbungle National Park on Mount Woorat, also known as Siding Spring Mountain. Siding Spring Observatory is owned by the Australian National University (ANU) and is part of the Mount Stromlo and Siding Spring Observatories research school.
The 2003 Canberra bushfires caused severe damage to the suburbs and outer areas of Canberra, the capital city of Australia, during 18–22 January 2003. Almost 70% of the Australian Capital Territory's (ACT) pastures, pine plantations, and nature parks were severely damaged, and most of the Mount Stromlo Observatory was destroyed. After burning for a week around the edges of the ACT, the fires entered the suburbs of Canberra on 18 January 2003. Over the next ten hours, four people died, over 490 were injured, and 470 homes were destroyed or severely damaged, requiring a significant relief and reconstruction effort.
The UK Schmidt Telescope (UKST) is a 1.24 metre Schmidt telescope operated by the Australian Astronomical Observatory ; it is located adjacent to the 3.9 metre Anglo-Australian Telescope at Siding Spring Observatory, Australia. It is very similar to the Samuel Oschin telescope in California. The telescope can detect objects down to magnitude 21 after an hour of exposure on photographic plates.
The 2.3 metre telescope at Siding Spring Observatory is operated by the Australian National University. The Advanced Technology Telescope was constructed during the early 1980s and featured, at the time, bold features and design: an unusually thin mirror, an alt-az mount and co-rotating dome. The optical telescope has Altazimuth mount and a primary mirror with a focal length of f/2.05. It is housed in a box-shaped building which rotates as the telescope tracks objects.
The Automated Patrol Telescope (APT) was a wide-field CCD imaging telescope, operated by the University of New South Wales at Siding Spring Observatory, Australia.
Mount Stromlo is a mountain with an elevation of 770 metres (2,530 ft) AHD that is situated in the Australian Capital Territory, Australia. The mountain is most notable as the location of the Mount Stromlo Observatory. The mountain forms part of the catchment area of the Cotter River which in turn is the primary water supply for part of ACT.
SkyMapper is a fully automated 1.35 m (4.4 ft) wide-angle optical telescope at Siding Spring Observatory in northern New South Wales, Australia. It is one of the telescopes of the Research School of Astronomy and Astrophysics of the Australian National University (ANU). The telescope has a compact modified Cassegrain design with a large 0.69 m secondary mirror, which gives it a very wide field of view: its single, dedicated instrument, a 268-million pixel imaging camera, can photograph 5.7 square degrees of sky. The camera has six light filters which span from ultraviolet to near infrared wavelengths.
Melbourne Observatory is an observatory located on a hill adjacent to the Royal Botanic Gardens Victoria. The observatory commenced operations in 1863 and was decommissioned from official Government work in 1945. The observatory has since continued as an astronomical observatory and remains open to the public. Melbourne Observatory is also permanently on the Australian National Heritage List under 'Melbourne's Domain Parkland and Memorial Precinct' since early 2018.
The Uppsala Schmidt Telescope is a Schmidt telescope located in Australia. It was moved to Siding Spring Observatory from Mount Stromlo Observatory in 1982. The instrument has been used to study galaxies, asteroids and comets. It was last dedicated to the Siding Spring Survey. The telescope had a field of view of just over 6° through the use of a correcting plate, making its field three times as large as that of the Anglo-Australian Telescope. It used a spherical rather than a parabolic mirror with 0.6 m correcting plate to achieve this. Photographic plates and film were used as detectors.
Harvey Raymond Butcher III is an astronomer who has made significant contributions in observational astronomy and instrumentation which have advanced understanding of the formation of stars and of the universe. He received a B.Sc. in Astrophysics from the California Institute of Technology in 1969, where he contributed to the development of advanced infrared spectrometry applied in the first survey of the sky at infrared wavelengths.

The National Computational Infrastructure is a high-performance computing and data services facility, located at the Australian National University (ANU) in Canberra, Australian Capital Territory. The NCI is supported by the Australian Government's National Collaborative Research Infrastructure Strategy (NCRIS), with operational funding provided through a formal collaboration incorporating CSIRO, the Bureau of Meteorology, the Australian National University, Geoscience Australia, the Australian Research Council, and a number of research-intensive universities and medical research institutes.
The Great Melbourne Telescope was built by the Grubb Telescope Company in Dublin, Ireland in 1868, and installed at the Melbourne Observatory in Melbourne, Australia in 1869. In 1945 that Observatory closed and the telescope was sold and moved to the Mount Stromlo Observatory near Canberra. It was rebuilt in the late 1950s. In 2003 the telescope, still in use as an observatory, was severely damaged in a bushfire. About 70% of the components were salvageable; a project to restore the telescope to working condition started in 2013.
Sidney Charles Bartholemew "Ben" Gascoigne was a New Zealand-born optical astronomer and expert in photometry who played a leading role in the design and commissioning of Australia's largest optical telescope, the Anglo-Australian Telescope, which for a time was one of the world's most important astronomical facilities. Born in Napier, New Zealand, Gascoigne trained in Auckland and at the University of Bristol, before moving to Australia during World War II to work at the Commonwealth Solar Observatory at Mount Stromlo in Canberra. He became skillful in the design and manufacture of optical devices such as telescope elements.
In astronomy, the MACHO Project was an observational search during 1992-1999 for dark matter around our Milky Way galaxy in the form of hypothetical Massive Compact Halo Objects (MACHOs), using the method of gravitational microlensing. It was one of three first-generation microlensing searches started in the early 1990s, the others being the independent EROS and OGLE projects. The MACHO project was carried out by a team of US and Australian astronomers; observations used the 1.27-metre (50-inch) telescope at the Mount Stromlo Observatory near Canberra, which was dedicated to the project full-time from 1992 until 1999. The project did not solve the dark matter problem, but placed important upper limits on the fraction of dark matter in MACHOs across a wide range of masses, and achieved several notable discoveries in the field of microlensing, and new results on several classes of variable stars.
The Astronomical Society of Victoria (ASV) is an amateur astronomy club in the state of Victoria, Australia. It was founded in 1922, making it one of the oldest such clubs in the country, and with some 1500 members it claims to be one of the largest amateur astronomy organisations in the southern hemisphere. Membership is open to all with an interest in astronomy, and the society caters for people with a wide range of ages, backgrounds, abilities and interests.
