Astronomer
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, natural satellite, moons, comets and galaxy, galaxies – in either observational astronomy, observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, Sun, solar astronomy, the Star formation, origin or stellar evolution, evolution of stars, or the galaxy formation and evolution, formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole. Types Astronomers usually fall under either of two main types: observational astronomy, observational and theoretical astronomy, theoretical. Observational astronomers make direct observations of Astronomical object, celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate C ...

Robert Grant Aitken
Robert Grant Aitken (December 31, 1864 – October 29, 1951) was an American astronomer. Early life and education Robert Grant Aitken was born in Jackson, California, to Scottish immigrant Robert Aitken and Wilhelmina Depinau. Aitken attended Williams College in Massachusetts and graduated with an undergraduate degree in 1887. Career From 1887–1891, he worked as a mathematics instructor at Livermore, California, then received his M.A. from Williams College in 1892. He became a professor of mathematics at the College of the Pacific, another liberal arts school. He was offered an assistant astronomer position at Lick Observatory in California in 1895. He began a systematically study of double stars, measuring their positions and calculating their orbits around one another. From 1899, in collaboration with W. J. Hussey, he methodically created a very large catalog of such stars. This ongoing work was published in Lick Observatory bulletins. In 1905, Hussey left and Aitk ...

George Biddell Airy
Sir George Biddell Airy (; 27 July 18012 January 1892) was an English mathematician and astronomer, and the seventh Astronomer Royal from 1835 to 1881. His many achievements include work on planetary orbits, measuring the mean density of the Earth, a method of solution of two-dimensional problems in solid mechanics and, in his role as Astronomer Royal, establishing Greenwich as the location of the prime meridian. Biography Airy was born at Alnwick, one of a long line of Airys who traced their descent back to a family of the same name residing at Kentmere, in Westmorland, in the 14th century. The branch to which he belonged, having suffered in the English Civil War, moved to Lincolnshire and became farmers. Airy was educated first at elementary schools in Hereford, and afterwards at Colchester Royal Grammar School. An introverted child, Airy gained popularity with his schoolmates through his great skill in the construction of peashooters. From the age of 13, Airy stayed frequ ...

Eva Ahnert-Rohlfs
Eva Ahnert-Rohlfs (11 August 1912 – 9 March 1954) was a German astronomer. She made key observations of variable stars. Eva Ahner-Rohlfs was born in Coburg (Duchy Saxe-Coburg-Gotha). She studied in Würzburg, Munich and Kiel from 1931 to 1933. After nine years of withdrawal into family life, she studied from 1942 until the end of the Second World War at the University of Göttingen. From 1945, she worked closely with professor Cuno Hoffmeister as an assistant astronomer at the Sonneberg Observatory. In 1951, she received a doctorate in astrophysics from the University of Jena. At Sonneberg Observatory Eva Rohlfs met the astronomer Paul Oswald Ahnert and they were married in 1952. From the Sonneberg observatory he made important observations of the variable stars that he detailed in the article "Zur Struktur und Entstehung des Perseidenstroms" ("On the structure and origin of the Perseid current") included in the Observatory Publications Sonneberg Astronomical.

Paul Oswald Ahnert
Paul Oswald Ahnert (22 November 1897 – 27 February 1989) was a German astronomer. He first became famous in Germany for publishing the ''"Kalender für Sternfreunde"'' from 1948 until 1988, an annual calendar of astronomical events. The minor planet 3181 Ahnert is named in his honor. Ahnert was born in Chemnitz, Kingdom of Saxony. During the First World War he served as an ordinary German field-soldier. After the war he became a member of the Social Democratic Party of Germany (SPD) and was a committed opponent of the rise of militarism and right wing revanchism in Germany. Between 1919 and 1933 he worked as an elementary school teacher. In addition to this he was an ambitious amateur astronomer and in 1923 his first article was published in the scientific journal Astronomische Nachrichten (AN 219 (1923), 165–170). He reported about long period variables he had observed from his private observatory. When Adolf Hitler became Chancellor in 1933 the Nazi regime removed P ...

Moon
The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density. The Moon orbits Earth at an average distance of , or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each synodic period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleiades
The Pleiades (), also known as The Seven Sisters, Messier 45 and other names by different cultures, is an asterism and an open star cluster containing middle-aged, hot B-type stars in the north-west of the constellation Taurus. At a distance of about 444 light years, it is among the nearest star clusters to Earth. It is the nearest Messier object to Earth, and is the most obvious cluster to the naked eye in the night sky. It is also observed to house the reflection nebula NGC 1432, an HII Ionized region. The cluster is dominated by hot blue luminous stars that have formed within the last 100 million years. Reflection nebulae around the brightest stars were once thought to be left over material from their formation, but are now considered likely to be an unrelated dust cloud in the interstellar medium through which the stars are currently passing. This dust cloud is estimated to be moving at a speed of approximately 18 km/s relative to the stars in the cluster. Computer sim ...

Agrippa (astronomer)
Agrippa ( el, Ἀγρίππας; ) was a Greek astronomer. The only thing that is known about him regards an astronomical observation that he made in 92 AD. Ptolemy writes that in the twelfth year of the reign of Domitian, on the seventh day of the Bithynian month ''Metrous'', Agrippa observed the occultation of a part of the Pleiades by the southernmost part of the Moon. The purpose of Agrippa's observation was probably to check the precession of the equinoxes, which was discovered by Hipparchus.
