George Carruthers
George Robert Carruthers (October 1, 1939 – December 26, 2020) was an African American inventor, physicist, engineer and space scientist. Carruthers perfected a compact and very powerful ultraviolet camera/spectrograph for NASA to use when it launched Apollo 16 in 1972. He designed it so astronauts could use it on the lunar surface, making all adjustments inside their bulky space suits. Upon instructions from Carruthers, they used the camera to record the Earth's outermost atmosphere, noting its variations, and also mapped portions of the far-ultraviolet sky recording stars and galaxies, and the gaseous media between them. In 1970, sending his instruments aboard Aerobee sounding rockets, he had demonstrated that molecular hydrogen exists in the interstellar medium. Among numerous citations and awards, in 2003, Carruthers was inducted into the National Inventors Hall of Fame, and he received an honorary doctorate for Engineering from Michigan Technological University. He also w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Young (astronaut)
John Watts Young (September 24, 1930 – January 5, 2018) was an American astronaut, naval officer and aviator, test pilot, and aeronautical engineer. He became the ninth person to walk on the Moon as commander of the Apollo 16 mission in 1972. He is the only astronaut to fly on four different classes of spacecraft: Gemini, the Apollo command and service module, the Apollo Lunar Module and the Space Shuttle. Before becoming an astronaut, Young received his Bachelor of Science degree in Aeronautical Engineering from the Georgia Institute of Technology and joined the U.S. Navy. After serving at sea during the Korean War he became a naval aviator and graduated from the U.S. Naval Test Pilot School. As a test pilot, he set several world time-to-climb records. Young retired from the Navy in 1976 with the rank of captain. In 1962, Young was selected as a member of NASA Astronaut Group 2. He flew on the first crewed Gemini mission (Gemini 3) in 1965, and then commanded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interstellar Medium
In astronomy, the interstellar medium is the matter and radiation that exist in the space between the star systems in a galaxy. This matter includes gas in ionic, atomic, and molecular form, as well as dust and cosmic rays. It fills interstellar space and blends smoothly into the surrounding intergalactic space. The energy that occupies the same volume, in the form of electromagnetic radiation, is the interstellar radiation field. The interstellar medium is composed of multiple phases distinguished by whether matter is ionic, atomic, or molecular, and the temperature and density of the matter. The interstellar medium is composed, primarily, of hydrogen, followed by helium with trace amounts of carbon, oxygen, and nitrogen. The thermal pressures of these phases are in rough equilibrium with one another. Magnetic fields and turbulent motions also provide pressure in the ISM, and are typically more important, dynamically, than the thermal pressure is. In the interstellar medium, ...

Adler Planetarium
The Adler Planetarium is a public museum in Chicago, Illinois, dedicated to astronomy and astrophysics. It was founded in 1930 by local businessman Max Adler. Located on the northeastern tip of Northerly Island on Lake Michigan in the city, the Adler Planetarium was the first planetarium in the United States. It is part of Chicago's Museum Campus, which includes the John G. Shedd Aquarium and The Field Museum. The Planetarium's mission is to inspire exploration and understanding of the universe. The Adler Planetarium opened to the public on May 12, 1930. Its architect, Ernest A. Grunsfeld Jr., was awarded the gold medal of the Chicago chapter of the American Institute of Architects in 1931 for its design. In 1987, it was declared a National Historic Landmark. and The Adler has three theaters, space science exhibitions, including the Gemini 12 space capsule, and a collection of antique scientific instruments and print materials. In addition, the Adler Planetarium hosts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

South Side, Chicago
The South Side is an area of Chicago, Illinois, U.S. It lies south of the city's Loop area in the downtown. Geographically, it is the largest of the three sides of the city that radiate from downtown, with the other two being the north and west sides. Much of the South Side came from the city's annexation of townships such as Hyde Park. The city's Sides have historically been divided by the Chicago River and its branches. The South Side of Chicago was originally defined as all of the city south of the main branch of the Chicago River, but it now excludes the Loop. The South Side has a varied ethnic composition and a great variety of income levels and other demographic measures. It has a reputation for crime, although most crime is contained within certain neighborhoods, not throughout the South Side itself, and residents range from affluent to middle class to poor. South Side neighborhoods such as Armour Square, Back of the Yards, Bridgeport, and Pullman host more blue colla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astronomy
Astronomy () is a natural science that studies astronomical object, celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and chronology of the Universe, evolution. Objects of interest include planets, natural satellite, moons, stars, nebulae, galaxy, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond atmosphere of Earth, Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Babylonian astronomy, Babylonians, Greek astronomy, Greeks, Indian astronomy, Indians, Egyptian astronomy, Egyptians, Chinese astronomy, Chinese, Maya civilization, Maya, and many anc ...

The area within Milford, Old Milford, and O'Bannon Township were all built on a survey by John Nancarrow, a Revolutionary War veteran from Virginia. O'Bannon, now Miami, Township was named for Clermont's first surveyor.
