Joseph Ritter von Fraunhofer was a German physicist and optical lens manufacturer. He made optical glass and achromatic telescope objective lenses, invented the spectroscope, and developed diffraction grating. In 1814, he discovered and studied the dark absorption lines in the spectrum of the sun now known as Fraunhofer lines.
A refracting telescope is a type of optical telescope that uses a lens as its objective to form an image. The refracting telescope design was originally used in spyglasses and astronomical telescopes but is also used for long-focus camera lenses. Although large refracting telescopes were very popular in the second half of the 19th century, for most research purposes, the refracting telescope has been superseded by the reflecting telescope, which allows larger apertures. A refractor's magnification is calculated by dividing the focal length of the objective lens by that of the eyepiece.
Wilhelm Heinrich Walter Baade was a German astronomer who worked in the United States from 1931 to 1959.
Karl Hermann von Struve was a Baltic German astronomer. In Russian, his name is sometimes given as German Ottovich Struve or German Ottonovich Struve.
Georg Heinrich Thiessen was a German astronomer.
Teide Observatory, IAU code 954, is an astronomical observatory on Mount Teide at 2,390 metres (7,840 ft), located on Tenerife, Spain. It has been operated by the Instituto de Astrofísica de Canarias since its inauguration in 1964. It became one of the first major international observatories, attracting telescopes from different countries around the world because of the good astronomical seeing conditions. Later the emphasis for optical telescopes shifted more towards Roque de los Muchachos Observatory on La Palma.
The Berlin Observatory is a German astronomical institution with a series of observatories and related organizations in and around the city of Berlin in Germany, starting from the 18th century. It has its origins in 1700 when Gottfried Leibniz initiated the "Brandenburg Society of Science″ which would later (1744) become the Prussian Academy of Sciences. The Society had no observatory but nevertheless an astronomer, Gottfried Kirch, who observed from a private observatory in Berlin. A first small observatory was furnished in 1711, financing itself by calendrical computations.
The Kodaikanal Solar Observatory is a solar observatory owned and operated by the Indian Institute of Astrophysics. It is on the southern tip of the Palani Hills 4 kilometres (2.5 mi) from Kodaikanal town.
The Einstein Tower is an astrophysical observatory in the Albert Einstein Science Park in Potsdam, Germany built by architect Erich Mendelsohn. It was built on the summit of the Potsdam Telegraphenberg to house a solar telescope designed by the astronomer Erwin Finlay-Freundlich. The telescope supports experiments and observations to validate Albert Einstein's relativity theory. The building was first conceived around 1917, built from 1919 to 1921 after a fund-raising drive, and became operational in 1924. Although Einstein never worked there, he supported the construction and operation of the telescope. It is still a working solar observatory today as part of the Leibniz Institute for Astrophysics Potsdam. Light from the telescope is directed down through the shaft to the basement where the instruments and laboratory are located. There were more than half a dozen telescopes in the laboratory.
Hugo von Seeliger, also known as Hugo Hans Ritter von Seeliger, was a German astronomer, often considered the most important astronomer of his day.
Gale Bruno van Albada was a Dutch astronomer, known for his orbital observations of binary stars and studies on the evolution of galaxy clusters.
Stéphane Udry is an astronomer at the Geneva Observatory in Switzerland, whose current work is primarily the search for extra-solar planets. He and his team, in 2007, discovered a possibly terrestrial planet in the habitable zone of the Gliese 581 planetary system, approximately 20 light years away in the constellation Libra. He also led the observational team that discovered HD 85512 b, another most promisingly habitable exoplanet.
The Vacuum Tower Telescope is an evacuated-optics solar telescope located at the Teide Observatory on Tenerife in the Canary Islands. It is operated by the Kiepenheuer-Institut für Sonnenphysik (KIS).
Leibniz Institute for Astrophysics Potsdam (AIP) is a German research institute. It is the successor of the Berlin Observatory founded in 1700 and of the Astrophysical Observatory Potsdam (AOP) founded in 1874. The latter was the world's first observatory to emphasize explicitly the research area of astrophysics. The AIP was founded in 1992, in a re-structuring following the German reunification.
Bosscha Observatory is the oldest modern observatory in Indonesia, and one of the oldest in Asia. The observatory is located in Lembang, West Java, approximately 15 kilometers (9.3 mi) north of Bandung. It is situated on a hilly six hectares of land and is 1,310 m (4,300 ft) above mean sea level plateau. The IAU observatory code for Bosscha is 299.
The Astronomische Gesellschaft is an astronomical society established in 1863 in Heidelberg, the second oldest astronomical society after the Royal Astronomical Society.
Karl-Otto Kiepenheuer was a German astronomer and astrophysicist. His research focused on the Sun, and for that purpose he initiated construction of several solar telescopes and founded the Kiepenheuer Institute for Solar Physics.
The Leibniz Institute for Solar Physics, formerly known as Kiepenheuer Institute for Solar Physics (KIS) is a research institute located in Freiburg, Germany. As a member of the Leibniz Association, the institute conducts basic research in astronomy and astrophysics with a particular focus on solar physics. The institute's structure and operation is based on three strategic pillars: 1) fundamental research, 2) operation of the German solar telescope infrastructure on Tenerife, and 3) applied research in data science and operation of the Science Data Center. Institute's Professors appointed and habilitated at the University of Freiburg offer lectures at various university degree levels and train young scientists.
Göttingen Observatory is a German astronomical observatory located in Göttingen, Lower Saxony, Germany.
Karel Albert Rudolf Bosscha, sometimes known as KAR Bosscha or Ru Bosscha was a planter, philanthropist and administrator of the Malabar Plantation in Bandung, Indonesia.
