Shamakhy Astrophysical Observatory, named after Nasir al-Din al-Tusi of the Azerbaijan National Academy of Sciences, was established in 1959 by the decision (17 November) of the Council of Ministers of the Azerbaijan Soviet Socialist Republic. However, the history of scientific research in the field of astrophysics goes back to previous years. In 1927, a permanently operating astronomical expedition was created to study Astro-climate in some regions of Azerbaijan. The expedition had to choose the best geographical location for the observatory in Kalbajar, Lachin, Shamakhy, Khizi and other regions of the republic. As a result of the investigations it was found out that the Pirgulu region of Shamakhy was the most suitable place for the creation of a scientific centre in this direction and in 1953, it was decided to build an observation base and later an observatory. The Center is part of the Astrophysics Department (1954), then the Astrophysics Sector of the Academy of Sciences of Azerbaijan (ASA) (1956), within the ASA Institute of Physics and Mathematics. In addition to astronomical observations in 1953-59, the future design of the observatory, the training of specialists in the field of astronomy, telescope and equipment supply, and the structure of the observatory was undertaken. In 1957 the first telescope was installed at the Pirgulu Astronomical Station (Chromosphere-Photosphere Solar Telescope). In 1959 the issue of studying the Astro-cyclicity of the area was solved by launching a 200-mm photoelectric telescope. Construction of the observatory began in 1958 in then Azerbaijan SSR and officially opened on January 13, 1960 . The observatory was created on the initiative of prominent Azerbaijani scientists Hasan Aliyev and Yusif Mammadaliyev. Yusif Mammadaliyev, the prominent Azerbaijani scientist, played a great role in the foundation of the observatory. In 1991, the observatory was given the name of Nasiraddin Tusi, a mathematician, physicist and astronomer of the Middle Ages. A settlement for the habitation of employees was established under the observatory and was named after Yusif Mammadaliyev (Pirgulu). In September 2008, the observatory went through capital repair, the exhibition hall, museum, conference and lecture halls, six buildings for telescopes, including the building housing the main two-metre telescope and main administrative building were overhauled, and a canteen and cottages built. The first director of Shamakhy Astrophysics Observatory was academician Hajibey Sultanov (1960–1981). The academy has great merits in the establishment and development of the observatory.
Shamakhy Astrophysical Observatory named after N. Tusi in modern times
Astrophysical observations were organized intensively, at the Shamakhy Observatory in 1960–1980. In those years, in the country, great attention was paid to the preparation of cadres in the field of astrophysics. To this end, in 1976 by the special order of national leader Heydar Aliyev, at the Azerbaijan State University was founded the Department of Astrophysics. To date, this department plays an important role, in the preparation of qualified cadres. In 1981, by the decision of the Cabinet of Ministers, Shamakhi Astrophysical Observatory was named after Nasreddin Tusi, the great astronomer of Azerbaijan. The Batabat Section of the SARS (1973) (Nakhchivan Autonomous Republic) and the Aghdara Astronomical Station (1997), were established under the Observatory. The Baku Branch of the Shamakhy Astrophysical Observatory plays an important role in the coordination of the observatory's activities and the establishment of mutual relations with other structures of ANAS. The Astronomy Museum also serves in the Observatory. The museum plays an important role in promoting the observatory and its astronomy as a whole.
The museum plays an important role in promoting of the observatory and its astronomy as a whole. The crater was named “Nadir Ibrahimov” on Mars, in honour of the deceased employee of the “SHAO” and a crater on the moon was named Nasreddin Tusi. At present, 13 of the names given to small celestial bodies, as well as to the crater of planets, are related to Azerbaijan. All this, undoubtedly, is an indication of the success of astronomy in Azerbaijan. On the basis of relevant orders of the President of the Republic of Azerbaijan Mr Ilham Aliyev, reconstruction works were carried out in Shamakhy Astrophysical Observatory named after N. Tusi in 2009–2013. As a result of the attention and care shown by Mr President to the Azerbaijani science, guest houses of the observatory was completely renovated, its main corpus was renovated (a new astronomy museum, a large conference hall,) a new laboratory building was built and telescopes were renovated, auxiliary facilities (dining-room, boiler-room, substation), were commissioned and large-scale landscaping works were implemented. New communication lines (gas, water, electricity, telephone,) that correspond to modern standards have been created, the double-telescope has been fully automated and modernized. For aluminizing of astronomical mirrors surface, vacuum unit B-240 was restored in 2007. A special building was built and put into service. For the first time in the history of the SHAO in 2013, the process of aluminizing the mirrors was carried out by local experts. The existence of this unique device allows the Shamakhy Astrophysics Observatory not only to open its mirrors but also to regularly cover the aluminium layer in the mirrors of the regional observatories.
Scientific research at the Observatory is based on two aspects Dynamics and Physics of Stellar Medium: "Comprehensive Study of Physical Variations in Stars and Nebulae", (the study of non-stationary processes occurring in celestial bodies and their nature) and "Physics of Solar system", "Physics and dynamics of bodies", "Dynamics and Physics of Active Structures in Solar Atmosphere", "Solar-Earth Relations", "Exploration of Planet Atmospheres and Their Satellites", Comet, Asteroid, Solar System Physics, Their Structure, Physics and Evolution. More than 100 monographs, textbooks, catalogues, and scientific-mass books were published by astronomers during the activity of the Observatory. The journal "Shao's circular" has a history of 40 years. Since 2006, the "Azerbaijan Astronomy Journal" has been published. Along with this, the observatory also closely participates in the publication of the international journal "Sun and Geosphere" in English. During the existence, its staff published over 2,500 papers in foreign and local journals.
"The Shamakhy Astrophysical Observatory has a very long history. Worldwide, it has a great influence on the world of science. I am very glad to see the reconstruction of this observatory and the wonderful conditions here. ... I am sure that this observatory will serve the people of Azerbaijan and Azerbaijani science for decades, decades later"
President of the Republic of Azerbaijan: scientists and specialists labouring at the Shamakhy Astrophysical Observatory, successfully continue their activities in many scientific institutions of the world, including the United States, Israel, Ukraine, Russia, and Turkey. A number of international and republican symposiums and conferences were held in Shamakhy Astrophysical Observatory. Among them are congresses of the International Astronautics Federation (1972), conferences dedicated to research of magnetic stars (1973, 1976), Plenum of the USSR SA Astronomical Council (1984), “Tusi-800” Conferences (8 conferences in 1998–2002) “Periodic and Cosmic Problems” (2003), "International Conference dedicated to the 60th Anniversary of the Foundation of the SHAO "(2013) and others. During the activity of the SHAO, the observatory staff carried out joint work with the foreign astronomers on a number of actual topics. Close cooperation with solar physics and solar-earth problems are carried out by separate astronomical organizations from Russia, Germany, Israel, Bulgaria, Georgia, and other countries. Studies are carried out jointly with the staff of several Russian observatories on the direction of astrophysics Russian AS XAR, State Astronomical Institute named after Sternberg of Moscow State University, St. Petersburg SU and others.

International collaboration and achievements
The Shamakhy observatory has made a significant contribution to extensive Soviet and post-Soviet scientific programmes in astrophysics and fundamental astronomy. The observatory works on three main scientific trends: the physics of stars, investigation of solar system bodies and solar physics and solar-terrestrial relations. Current investigations also include the effects of space weather, the history of astronomy, theoretical astrophysics, cosmology, helioseismology, radio-astronomy, practical astronomy, celestial mechanics, galaxies and the dynamics of artificial satellites. In recent years, a new area of work has been the development and construction of astronomical devices such as Echelle spectrographs, used for investigations of celestial bodies.
The observatory is best known to the Azerbaijani public for its specifications of the exact time of holidays, such as the traditional new year, Novruz. The observatory tells the media the moment of the vernal equinox, the time when the Sun will cross the equator, which marks the start of the new year.
