Historically, astronomical observatories consisted generally in a building or group of buildings where observations of astronomical objects such as sunspots, planets, asteroids, comets, stars, nebulae, and galaxies in the visible wavelengths of the electromagnetic spectrum were conducted. At first, for millennia, astronomical observations have ...
This led to the emergence of the first astronomical observatories in the Muslim world by the early 9th century. [49] [50] Zij star catalogues were produced at these observatories. In the 9th century, Persian astrologer Albumasar was thought to be one of the greatest astrologer at that time.
Uraniborg was an astronomical observatory and alchemy laboratory established and operated by the Danish astronomer Tycho Brahe. It was the first custom-built observatory in modern Europe, and the last to be built without a telescope as its primary instrument.
Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based.Historically, ground-based observatories were as simple as containing an astronomical sextant (for measuring the distance between stars) or Stonehenge (which has some alignments on astronomical phenomena).
The first permanent mountaintop astronomical observatory was the Lick Observatory constructed from 1876 to 1887, at the modest elevation of 1,283 m (4,209 ft) atop Mount Hamilton in California. [2] The first high altitude observatory was constructed atop the 2,877 m (9,439 ft) Pic du Midi de Bigorre in the French Pyrenees starting in 1878, with ...
1970 — The first space observatory, Uhuru, is launched, being also the first gamma-ray telescope. 1975 — BTA-6 is the first major telescope to use an altazimuth mount, which is mechanically simpler but requires computer control for accurate pointing. The Oldest Observatory in the Americas is found in Bogotá, Colombia (1803).
The first astronomical texts that were translated into Arabic were of Indian [2] and Persian origin. [3] The most notable was Zij al-Sindhind, a zij produced by Muḥammad ibn Ibrāhīm al-Fazārī and Yaʿqūb ibn Ṭāriq, who translated an 8th-century Indian astronomical work after 770, with the assistance of Indian astronomers who were at the court of caliph Al-Mansur.
