Penteli Observatory
The Penteli Observatory (Greek language, Greek: Αστεροσκοπείο Πεντέλης), also known as the Penteli Astronomical Stationis (Αστρονομικός Σταθμός Πεντέλης), is an astronomical observatory in Penteli, Greece, Penteli, Greece, operated by the National Observatory of Athens. It is best known for housing the historic Newall Refractor, which was the largest refracting telescope in the world when it was built in 1869. From 1959 to 1980 it was a major site for scientific research, though since then it has been facing severe light pollution problems resulting in its gradual conversion into a public observatory, especially after the establishment of the Visitor Center there in 1995. Nowadays, the most notable research conducted in the location is the one carried out by the Athens Digisonde, an ionosonde used for ionospheric sounding. History Background and early years During the decade of 1930, Stavros Plakidis, then director of the Nati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Observatory Of Athens
The National Observatory of Athens (NOA; ) is a research institute in Athens, Greece. Founded in 1842, it is the oldest List of research institutes in Greece, research foundation in Greece. The Observatory was the first scientific research institute built after Greece became independent in 1829, and one of the oldest research institutes in Southern Europe. It was built around the same period as the United States Naval Observatory. The world-renowned Greek-Austrian astronomer Georgios Konstantinos Vouris lobbied to create the National Observatory of Athens in the newly founded state. He persuaded wealthy Greek-Austrian banker Georgios Sinas to pay for the new massive observatory. The Austrian-born Otto of Greece, Greek King found out the news and awarded Georgios Sinas's son the Order of the Redeemer. The King also selected the architects for the building under Georgios Konstantinos Vouris's supervision, which were Eduard Schaubert and Theophil Hansen. The Athens observatory sinc ...

Mount Pentelicus
Mount Pentelicus or Pentelikon (, or ) is a mountain in Attica, Greece, situated northeast of Athens and southwest of Marathon. Its highest point is the peak ''Pyrgari'', with an elevation of 1,109 m. The mountain is covered in large part with forest (about 60 or 70%), and can be seen from southern Athens (Attica), the Pedia plain, Parnitha, and the southern part of the northern suburbs of Athens. Houses surround the mountain, especially in Vrilissia, Penteli, Ekali, Dionysos, and north of Gerakas. Marble from Mount Pentelicus is of exceptionally high quality and was used to construct much of the Athenian Acropolis. Later, Pentelic marble was exported to Rome, where it was used in construction and in sculptures. In ancient times it was also called Brilessos or Brilettos (, ) which is the origin of the name of the nearby suburb of Vrilissia. Pentelic marble Mount Pentelicus has been famous for its marble since antiquity. Pentelic marble was used for the construction ...

Science Communication
Science communication encompasses a wide range of activities that connect science and society. Common goals of science communication include informing non-experts about scientific findings, raising the Public awareness of science, public awareness of and interest in science, influencing people's attitudes and behaviors, informing public policy, and Public engagement, engaging with diverse communities to address societal problems. The term "science communication" generally refers to settings in which audiences are not experts on the scientific topic being discussed (Science outreach, outreach), though some authors categorize expert-to-expert communication ("inreach" such as publication in scientific journals) as a type of science communication. Examples of outreach include science journalism and health communication. Since science has political, moral, and legal implications, science communication can help bridge gaps between different stakeholders in public policy, industry, an ...

Kryoneri Observatory
The Kryoneri Observatory (Greek: Αστεροσκοπείο Κρυονερίου), also known as the Kryoneri Astronomical Station (Αστρονομικός Σταθμός Κρυονερίου), is an astronomical observatory in Corinthia, Greece, operated by the IAASARS research institute of the National Observatory of Athens. It is home of one of the largest telescopes in Greece, a Cassegrain reflector, which was used for the NELIOTA project of ESA and NOA. The observatory is also housing smaller instruments that are conducting research for IAASARS and are participating in international programmes. History The Kryoneri Observatory was established in 1972 and in 1975 its first telescope was installed, a Cassegrain reflector manufactured by Grubb Parsons, a British company based in Newcastle. The telescope was financed by the bequest of Marinos Korgialenios, a businessman and national benefactor of Greece who had bequested 200,000 drachmes to the National Observatory of ...

Arthur Eddington
Sir Arthur Stanley Eddington, (28 December 1882 – 22 November 1944) was an English astronomer, physicist, and mathematician. He was also a philosopher of science and a populariser of science. The Eddington limit, the natural limit to the luminosity of stars, or the radiation generated by accretion onto a compact object, is named in his honour. Around 1920, he foreshadowed the discovery and mechanism of nuclear fusion processes in stars, in his paper "The Internal Constitution of the Stars".The Internal Constitution of the Stars A. S. Eddington The Scientific Monthly Vol. 11, No. 4 (Oct., 1920), pp. 297–303 At that time, the source of stellar energy was a complete mystery; Eddington was the first to correctly speculate that the source was fusion of hydrogen into helium. Eddington wrote a number of articles that announced and explained Einstein's theory of general relativity to the English-speaking world. World War I had severed many lines of scientific communication, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cambridge Observatory
Cambridge Observatory is an astronomical observatory at the University of Cambridge in the East of England. It was established in 1823 and is now part of the site of the Institute of Astronomy. The old Observatory building houses the Institute of Astronomy Library which has a collection of modern and historical astronomical books. There are a set of optical telescopes at the site on the Madingley Road in the west of Cambridge. By modern standards these are small, as well as being affected by light pollution. The 36-inch telescope was used for studies of stellar radial velocities until 2019, and the historic Northumberland and Thorrowgood telescopes are used as part of the public outreach activities of the Institute. From 1990 to 1998, the Royal Greenwich Observatory was based in Cambridge in Greenwich House, just to the north of the Observatory.

Newall Telescope
The Newall Telescope is a refractor in the Penteli Observatory in Penteli, Greece. It was built in 1869 by Thomas Cooke for Robert Stirling Newall and when completed it was the largest refracting telescope in the world. It was located at Newall's private observatory until 1891, when it was moved to the Cambridge Observatory where it stayed until its donation to the National Observatory of Athens and its move to the Penteli Observatory in 1959. The telescope is still operational, though it is only used for educational purposes. History Construction In 1862, Scottish engineer and amateur astronomer Robert Stirling Newall found out about two large crystals made of crown and flint glass that were produced by Chance of Birmingham. He bought them for 500 pounds each and entrusted Thomas Cooke for the construction of the world's largest telescope using these crystals. Newall knew about Cooke thanks to his friend and fellow amateur astronomer Hugh Lee Pattinson, who had boug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
