University Of Denver
The University of Denver (DU) is a private research university in Denver, Colorado, United States. Founded in 1864, it has an enrollment of approximately 5,700 undergraduate students and 7,200 graduate students. It is classified among "R1: Doctoral Universities – Very high research activity". The main campus is a designated arboretum and is located five miles (8 km) south of downtown Denver. History In March 1864, John Evans, former governor of the Colorado Territory, appointee of President Abraham Lincoln, founded the Colorado Seminary in the newly created (1858) city of Denver, which was then a mining camp. Evans, governor and superintendent of Indian affairs of the Colorado Territory, lost his government position as a result of the November 1864 Sand Creek massacre (which was carried out by Colonel John Chivington, later a member of the Colorado Seminary's Trustees). At its founding the seminary was non-sectarian and operated by the Methodist Episcopal Chur ...

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. It 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 hemisphere of the Moon that is facing away from Earth, the opposite hemisphere is the near side. It always has the same surface oriented away from Earth 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 maria ("seas"), giving it an appearance closer to other barren places in the Solar System such as Mercury and Callisto. It has one of the largest craters in the Solar System, the South Pole–Aitken basin. The hemisphere has sometimes been called the "Dark side of the Moon", where "dark" means "unknown" instead of "lacking sunlight" each location on the Moon experiences two weeks of sunlight while the opposite location experiences night. About 18 percent of the far side is occasionally visible from Earth due to oscillation and to libration. The remaining 82 percent remained unobserved until 1959, when ...

Cleveland
Cleveland is a city in the U.S. state of Ohio and the county seat of Cuyahoga County. Located along the southern shore of Lake Erie, it is situated across the Canada–U.S. maritime border and approximately west of the Ohio-Pennsylvania state border. Cleveland is the most populous city on Lake Erie, the second-most populous city in Ohio, and the 53rd-most populous city in the U.S. with a population of 372,624 in 2020.

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 ...

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, of ...

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 until 2018. Ownership was transferred to the non-profit Yerkes Future Foundation (YFF) in May 2020, which began millions of dollars of restoration and renovation of the historic building and grounds. Yerkes re-opened for public tours and programming in May 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 40-in aperture (102 cm) doublet len ...

6P/d'Arrest
6P/d'Arrest (also known as d'Arrest's Comet or Comet d'Arrest) is a List of periodic comets, periodic Jupiter-family comet, 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. It was first observed by Heinrich Ludwig d'Arrest, in Leipzig, Germany, on 28th and 30 June 1851. 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. The comet 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 (astronomy), elongation of less than 30 degrees from October 20 ...
