San Cristóbal De Las Casas
San Cristóbal de las Casas (), also known by its native Tzotzil name, Jovel (), is a town and municipality located in the Central Highlands region of the Mexican state of Chiapas. It was the capital of the state until 1892, and is still considered the cultural capital of Chiapas. The municipality is mostly made up of mountainous terrain, but the city sits in a small valley surrounded by hills. The city’s center maintains its Spanish colonial layout and much of its architecture, with red tile roofs, cobblestone streets and wrought iron balconies often with flowers. Most of the city’s economy is based on commerce, services and tourism. Tourism is based on the city’s history, culture and indigenous population, although the tourism itself has affected the city, giving it foreign elements. Major landmarks of the city include the Cathedral, the Santo Domingo church with its large open air crafts market and the Casa Na Bolom museum. The municipality has suffered severe def ...

Nebulae
A nebula ('cloud' or 'fog' in Latin; pl. nebulae, nebulæ or nebulas) is a distinct luminescent part of interstellar medium, which can consist of ionized, neutral or molecular hydrogen and also cosmic dust. Nebulae are often star-forming regions, such as in the " Pillars of Creation" in the Eagle Nebula. In these regions, the formations of gas, dust, and other materials "clump" together to form denser regions, which attract further matter, and eventually will become dense enough to form stars. The remaining material is then thought to form planets and other planetary system objects. Most nebulae are of vast size; some are hundreds of light-years in diameter. A nebula that is visible to the human eye from Earth would appear larger, but no brighter, from close by. The Orion Nebula, the brightest nebula in the sky and occupying an area twice the angular diameter of the full Moon, can be viewed with the naked eye but was missed by early astronomers. Although denser than the space s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mount Wilson Observatory
The Mount Wilson Observatory (MWO) is an astronomical observatory in Los Angeles County, California, United States. The MWO is located on Mount Wilson, a peak in the San Gabriel Mountains near Pasadena, northeast of Los Angeles. The observatory contains two historically important telescopes: the Hooker telescope, which was the largest aperture telescope in the world from its completion in 1917 to 1949, and the 60-inch telescope which was the largest operational telescope in the world when it was completed in 1908. It also contains the Snow solar telescope completed in 1905, the 60 foot (18 m) solar tower completed in 1908, the 150 foot (46 m) solar tower completed in 1912, and the CHARA array, built by Georgia State University, which became fully operational in 2004 and was the largest optical interferometer in the world at its completion. Due to the inversion layer that traps warm air and smog over Los Angeles, Mount Wilson has steadier air than any other location in Nor ...

William Wilson Morgan
William Wilson Morgan (January 3, 1906 – June 21, 1994) was an American astronomer and astrophysicist. The principal theme in Morgan's work was stellar and galaxy classification. He is also known for helping prove the existence of spiral arms in our galaxy. In addition to his scientific achievements he served as a professor and as astronomy director for University of Chicago, and was the managing editor for George Hale's Astrophysical Journal. Scientific achievements Along with Philip Keenan he developed the MK system for the classification of stars through their spectra. He also developed several galaxy morphological classification systems, including the first systems to use the physical, quantifiable properties of galaxies, as opposed to simple, qualitative, eyeball estimates favoured by Edwin Hubble. He invented the now widely used classification cD for massive galaxies in the centres of galaxy clusters. In 1970, along with astronomer Laura P. Bautz, they created the stil ...

Gerhard Herzberg
Gerhard Heinrich Friedrich Otto Julius Herzberg, (; December 25, 1904 – March 3, 1999) was a German-Canadian pioneering physicist and physical chemist, who won the Nobel Prize for Chemistry in 1971, "for his contributions to the knowledge of electronic structure and geometry of molecules, particularly free radicals". Herzberg's main work concerned atomic and molecular spectroscopy. He is well known for using these techniques that determine the structures of diatomic and polyatomic molecules, including free radicals which are difficult to investigate in any other way, and for the chemical analysis of astronomical objects. Herzberg served as Chancellor of Carleton University in Ottawa, Ontario, Canada from 1973 to 1980. Early life and family Herzberg was born in Hamburg, Germany on December 25, 1904 to Albin H. Herzberg and Ella Biber. He had an older brother, Walter, who was born in January 1904. Herzberg started Vorschule (pre-school) late, after contracting measles. Ger ...
