Albert William Recht
Albert William Recht (1898–1962) was an American mathematician and astronomer. Initially he applied to work as a Spanish instructor at University of Denver. Instead he was hired by the Mathematics Department. He became chair of the mathematics department in 1943–44 and 1947–49. While at the university he pursued his interest in astronomy, working at the Chamberlin Observatory under the instruction of Herbert Howe. In 1926 Recht became director of the observatory, and full director in 1928. Over the following eleven years he studied during the summer months to earn his Ph.D. from the University of Chicago in 1939, working at Yerkes Observatory. He did his thesis work on the 6P/d'Arrest comet. Following his graduation, he was most noted for his work on the popularization of astronomy. During the 1950s he began a popular program of public viewing nights at the observatory. However his efforts to preserve the observatory at the time were unsuccessful. The crater ...

Chamberlin Observatory
Chamberlin Observatory is an astronomical observatory owned and operated by the University of Denver. It is located in Denver, Colorado (US) in Observatory Park. It is named for Humphrey B. Chamberlin, a Denver real estate magnate who pledged $50,000 in 1888 to build and equip the facility. The observatory building was designed by Robert S. Roeschlaub, with the astronomical aspects and functions designed by Professor Herbert Alonzo Howe after he visited many observatories in the east. It was modeled after the Goodsell Observatory at Carleton College in Northfield, Minnesota, and constructed from rusticated red sandstone blocks. The Romanesque structure includes a central rotunda and domed roof. Construction began in 1890. The 20-inch objective lens for the observatory's main refracting telescope was made by Alvan Clark & Sons, and the mount was built by George Nicholas Saegmuller. The mount rests on a cast iron pillar which is in turn supported by a massive stone pier. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herbert Alonzo Howe
Herbert Alonzo Howe (November 22, 1858 – November 2, 1926) was an American astronomer and educator. Biography Born in Brockport, New York, he was the son of Alonzo J. Howe, a professor at the old University of Chicago, and Julia M. Osgood. During his youth he developed an interest in the stars, witnessing the spectacular Leonid meteor shower of November, 1866. He matriculated to the old University of Chicago, where he graduated with an A.B. in 1875 at the age of sixteen. Joining the staff of the Cincinnati Observatory as an assistant, he worked primarily on computing orbital elements and observing double stars. In 1877, he was awarded his A.M. degree from the University of Cincinnati under Professor Ormond Stone. Long hours of work had left him with health issues, and in 1880 he had two severe pulmonary hemorrhages. As a consequence, he began to consider moving to a different climate. Fortunately, the chancellor of the recently formed University of Denver in Denver, Colorado offe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yerkes Observatory
Yerkes Observatory ( ) is an astronomical observatory located in Williams Bay, Wisconsin, United States. The observatory was operated by the University of Chicago Department of Astronomy and Astrophysics from its founding in 1897 to 2018. Ownership was transferred to the non-profit Yerkes Future Foundation (YFF) in May 2020, which began restoration and renovation of the historic building and grounds. Re-opening for public tours and programming began May 27, 2022. The observatory, often called "the birthplace of modern astrophysics," was founded in 1892 by astronomer George Ellery Hale and financed by businessman Charles T. Yerkes. It represented a shift in the thinking about observatories, from their being mere housing for telescopes and observers, to the early-20th-century concept of observation equipment integrated with laboratory space for physics and chemistry analysis. The observatory's main dome houses a doublet lens refracting telescope, the largest refractor ever ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
6P/d'Arrest
6P/d'Arrest (also known as d'Arrest's Comet or Comet d'Arrest) is a periodic Jupiter-family comet in the Solar System, orbiting between Mars and Jupiter. It passed from the Earth on August 12, 1976. The most recent perihelion passage took place on September 17, 2021, when the comet had a solar elongation of 95 degrees at approximately apparent magnitude of 10. The comet last came to perihelion (closest approach to the Sun) on March 2, 2015, but it was in an unfavorable apparition as it had a solar elongation of less than 30 degrees from October 2014 until May 2015. In 1991, Andrea Carusi and Giovanni B. Valsecchi ( Istituto Astrofisica Spaziale, Rome), and Ľubor Kresák and Margita Kresáková ( Slovak Astronomical Institute, Bratislava) independently suggested this comet was the same as a comet observed by Philippe de La Hire in 1678. It was first observed by Heinrich Ludwig d'Arrest, in Leipzig, Germany, on 28th and 30 June 1851. The comet nucleus is estimated at a ...

Recht (crater)
Recht is a small impact crater on the far side of the Moon. It was named after the American mathematician and astronomer Albert William Recht. Is lies across the eastern rim of the much larger crater Ostwald. To the northeast of Recht is Meshcherskiy. This is a bowl-shaped formation with an interior floor that is less than half the diameter of the crater. The inner walls have a higher albedo than the surrounding terrain, while the interior floor is about the same shade of grey.

Far Side Of The Moon
The far side of the Moon is the lunar hemisphere that always faces away from Earth, opposite to the Near side of the Moon, near side, because of synchronous rotation in the Moon's orbit. Compared to the near side, the far side's terrain is rugged, with a multitude of impact craters and relatively few flat and dark lunar mare, lunar maria ("seas"), giving it an appearance closer to other barren places in the Solar System such as Mercury (planet), Mercury and Callisto (moon), Callisto. It has one of the largest craters in the Solar System, the South Pole–Aitken basin. The hemisphere is sometimes called the "dark side of the Moon", where "dark" means "unknown" instead of "lacking sunlight" each side of the Moon experiences two weeks of sunlight while the opposite side experiences two weeks of night. About 18 percent of the far side is occasionally visible from Earth due to libration. The remaining 82 percent remained unobserved until 1959, when it was photographed by the Sovie ...
