Attilio Colacevich
Attilio Colacevich (; 25 July 1906 – 24 August 1953) was an Italian astronomer. Biography Colacevich was born in Fiume. He graduated in physics from the University of Florence in 1929, and in 1933 Giorgio Abetti hired him as assistant to the Arcetri Observatory. In 1934 he obtained a fellowship from the Rockefeller Foundation at the Lick Observatory carrying out research on spectroscopic binaries. In June 1948 he was appointed director of the Collurania astronomical observatory in Teramo and, a few months later, director of the Astronomical Observatory of Capodimonte in Naples. In 1949 he returned to America, first at the Warner and Swasey Observatory in Cleveland making observations with Jason Nassau with the Burrell-Schmidt telescope for studies on the spectroscopic classification of red stars, then he moved to Chicago at the Yerkes Observatory, and finally stayed for a month in Texas at the McDonald Observatory. Here he collaborated with Otto Struve who called him ''o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiume
Rijeka ( , , ; also known as Fiume hu, Fiume, it, Fiume ; local Chakavian: ''Reka''; german: Sankt Veit am Flaum; sl, Reka) is the principal seaport and the third-largest city in Croatia (after Zagreb and Split). It is located in Primorje-Gorski Kotar County on Kvarner Bay, an inlet of the Adriatic Sea and in 2021 had a population of 108,622 inhabitants. Historically, because of its strategic position and its excellent deep-water port, the city was fiercely contested, especially between the Holy Roman Empire, Italy and Croatia, changing rulers and demographics many times over centuries. According to the 2011 census data, the majority of its citizens are Croats, along with small numbers of Serbs, Bosniaks and Italians. Rijeka is the main city and county seat of the Primorje-Gorski Kotar County. The city's economy largely depends on shipbuilding (shipyards "3. Maj" and "Viktor Lenac Shipyard") and maritime transport. Rijeka hosts the Croatian National Theatre Ivan pl. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warner And Swasey Observatory
The Warner and Swasey Observatory is the astronomical observatory of Case Western Reserve University. Named after Worcester R. Warner and Ambrose Swasey, who built it at the beginning of the 20th century, it was initially located on Taylor Road in East Cleveland, Ohio, USA. The observatory, which at that time housed a refractor, was donated in 1919 to the Case School of Applied Science. The newer Burrell Schmidt telescope was built in 1939. Due to rising light pollution in Cleveland, a new station in Geauga County's Montville Township was established in 1950s. Named after Jason John Nassau, the station initially housed the Burrell telescope, which was later moved to Kitt Peak National Observatory. Instead of Burrell the station was equipped with the 36-inch robotic telescope. In 2008 Nassau Station was sold to the Geauga Park District and subsequently incorporated into its Observatory Park. The observatory currently operates the old 9.5-inch refractor (now known as the roof ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

President Of Italy
The president of Italy, officially denoted as president of the Italian Republic ( it, Presidente della Repubblica Italiana) is the head of state of Italy. In that role, the president represents national unity, and guarantees that Italian politics comply with the Constitution. The president is the commander-in-chief of the Italian Armed Forces and chairs the High Council of the Judiciary. A president's term of office lasts for seven years. The incumbent president is former constitutional judge Sergio Mattarella, who was elected on 31 January 2015, and re-elected on 29 January 2022. Qualifications for office The framers of the Constitution of Italy intended for the president to be an elder statesman of some stature. Article 84 states that any Italian citizen who is fifty or older on election day and enjoys civil and political rights can be elected president. The article also states that the presidency is incompatible with any other office; therefore, the president-elect mu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Astronomical Union
The International Astronomical Union (IAU; french: link=yes, Union astronomique internationale, UAI) is a nongovernmental organisation with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation. It was founded in 1919 and is based in Paris, France. The IAU is composed of individual members, who include both professional astronomers and junior scientists, and national members, such as professional associations, national societies, or academic institutions. Individual members are organised into divisions, committees, and working groups centered on particular subdisciplines, subjects, or initiatives. As of 2018, the Union had over 13,700 individual members, spanning 90 countries, and 82 national members. Among the key activities of the IAU is serving as a forum for scientific conferences. It sponsors nine annual symposia and holds a triannual General Assembly that sets policy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Accademia Dei Lincei
The Accademia dei Lincei (; literally the "Academy of the Lynx-Eyed", but anglicised as the Lincean Academy) is one of the oldest and most prestigious European scientific institutions, located at the Palazzo Corsini on the Via della Lungara in Rome, Italy. Founded in the Papal States in 1603 by Federico Cesi, the academy was named after the lynx, an animal whose sharp vision symbolizes the observational prowess that science requires. Galileo Galilei was the intellectual centre of the academy and adopted "Galileo Galilei Linceo" as his signature. "The Lincei did not long survive the death in 1630 of Cesi, its founder and patron", and "disappeared in 1651". During the nineteenth century, it was revived, first in the Vatican and later in the nation of Italy. Thus the Pontifical Academy of Science, founded in 1847, claims this heritage as the ''Accademia Pontificia dei Nuovi Lincei ("Pontifical Academy of the New Lynxes")'', descending from the first two incarnations of the Academy. ...

Solar Eclipse
A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby obscuring the view of the Sun from a small part of the Earth, totally or partially. Such an alignment occurs during an eclipse season, approximately every six months, during the new moon phase, when the Moon's orbital plane is closest to the plane of the Earth's orbit. In a total eclipse, the disk of the Sun is fully obscured by the Moon. In partial and annular eclipses, only part of the Sun is obscured. Unlike a lunar eclipse, which may be viewed from anywhere on the night side of Earth, a solar eclipse can only be viewed from a relatively small area of the world. As such, although total solar eclipses occur somewhere on Earth every 18 months on average, they recur at any given place only once every 360 to 410 years. If the Moon were in a perfectly circular orbit and in the same orbital plane as Earth, there would be total solar eclipses once a month, at every new moon. Instead, because the Moon ...

32 Cygni
32 Cygni (32 Cyg, Omicron2 Cyg, ο2 Cyg) is the Flamsteed designation for a binary star system in the Cygnus constellation. It is a 4th magnitude star, which can be seen with the naked eye under suitably dark skies. Parallax measurements give an estimated distance of 1,100 light-years (320 parsecs) from the Earth. However, Schröder et al. (2007) suggest the actual value, after correcting for Malmquist bias, may be closer to 1,174 light-years (360 parsecs). Although it is a spectrsocopic binary with components that cannot be separated visually, it has two entries in the Henry Draper Catalogue, with identical magnitudes and positions, but showing the spectral types of the two components. The Bayer letter ο has been variously applied to two or three of the stars 30, 31, and 32 Cygni. 32 Cygni has been designated as either ο2 or ο3 Cygni. For clarity, it is preferred to use the Flamsteed designation 32 Cygni rather than one of the Bayer designati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gerard Kuiper
Gerard Peter Kuiper (; ; born Gerrit Pieter Kuiper; 7 December 1905 – 23 December 1973) was a Dutch astronomer, planetary scientist, selenographer, author and professor. He is the eponymous namesake of the Kuiper belt. Kuiper is considered by many to be the father of modern planetary science. Early life and career Kuiper, the son of a tailor in the village of Tuitjenhorn in North Holland, had an early interest in astronomy. He had extraordinarily sharp eyesight, allowing him to see with the naked eye magnitude 7.5 stars, about four times fainter than those visible to normal eyes. He studied at Leiden University in 1924, where at the time a very large number of astronomers had congregated. He befriended fellow students Bart Bok and Pieter Oosterhoff, and was taught by Ejnar Hertzsprung, Antonie Pannekoek, Willem de Sitter, Jan Woltjer, Jan Oort, and the physicist Paul Ehrenfest. He received his candidate degree in Astronomy in 1927 and continued straight on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otto Struve
Otto Struve (August 12, 1897 – April 6, 1963) was a Russian-American astronomer of Baltic German origins. In Russian, his name is sometimes given as Otto Lyudvigovich Struve (Отто Людвигович Струве); however, he spent most of his life and his entire scientific career in the United States. Otto was the descendant of famous astronomers of the Struve family; he was the son of Ludwig Struve, grandson of Otto Wilhelm von Struve and great-grandson of Friedrich Georg Wilhelm von Struve. He was also the nephew of Karl Hermann Struve. With more than 900 journal articles and books, Struve was one of the most distinguished and prolific astronomers of the mid-20th century. He served as director of Yerkes, McDonald, Leuschner and National Radio Astronomy Observatories and is credited with raising worldwide prestige and building schools of talented scientists at Yerkes and McDonald observatories.
