Helen Chambliss Williams Lines (July 13, 1918 – January 29, 2001) was an American amateur astronomer. In her beginnings she was a deep-sky observer and astrophotographer. Astronomy In 1969, Lines was one of early members of the Phoenix Astronomical Society. Lines was a member of the American Association of Variable Star Observers. She and her husband, civil engineer Richard D. Lines, built a small observatory in Mayer, Arizona, and wrote about its construction for ''Sky & Telescope''. In 1992 they won the Amateur Achievement Award of the Astronomical Society of the Pacific for their work in the field of photoelectric photometry of variable stars.

Amateur Astronomy
Amateur astronomy is a hobby where participants enjoy observing or imaging celestial objects in the sky using the unaided eye, binoculars, or telescopes. Even though scientific research may not be their primary goal, some amateur astronomers make contributions in doing citizen science, such as by monitoring variable stars, double stars, sunspots, or occultations of stars by the Moon or asteroids, or by discovering transient astronomical events, such as comets, galactic novae or supernovae in other galaxies. Amateur astronomers do not use the field of astronomy as their primary source of income or support, and usually have no professional degree in astrophysics or advanced academic training in the subject. Most amateurs are hobbyists, while others have a high degree of experience in astronomy and may often assist and work alongside professional astronomers. Many astronomers have studied the sky throughout history in an amateur framework; however, since the beginning of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

People From Forrest City, Arkansas
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Otto Kippes
Otto Kippes (23 July 1905 – 2 February 1994) was a German Catholic priest and amateur astronomer, born in Bamberg, Bavaria. He was acknowledged especially for his work in asteroid orbit calculations, which brought him the Amateur Achievement Award of the Astronomical Society of the Pacific in 1991. In 1959, the Berlin Academy of Sciences awarded him the Leibniz Medal for his contributions in the identification of minor planets.http://www.nd-archiv.de/ausgabe/1959-07-03 Online. The main belt asteroid 1780 Kippes was named in his honour. Kippes in turn had successfully proposed to name several asteroids after fellow amateur astronomers.

Forrest City, Arkansas
Forrest City is a city in St. Francis County, Arkansas, United States, and the county seat. It was named for General Nathan Bedford Forrest, who used the location as a campsite for a construction crew completing a railroad between Memphis and Little Rock, shortly after the Civil War. The population was 15,371 at the 2010 census, an increase from 14,774 in 2000. The city refers to itself as the "Jewel of the Delta". History On October 13, 1827, St. Francis County, located in the east central part of Arkansas, was officially organized by the Arkansas Territorial Legislature in Little Rock.

The route traversed the challenging ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Variable Star
A variable star is a star whose brightness as seen from Earth (its apparent magnitude) changes with time. This variation may be caused by a change in emitted light or by something partly blocking the light, so variable stars are classified as either: * Intrinsic variables, whose luminosity actually changes; for example, because the star periodically swells and shrinks. * Extrinsic variables, whose apparent changes in brightness are due to changes in the amount of their light that can reach Earth; for example, because the star has an orbiting companion that sometimes eclipses it. Many, possibly most, stars have at least some variation in luminosity: the energy output of the Sun, for example, varies by about 0.1% over an 11-year solar cycle. Discovery An ancient Egyptian calendar of lucky and unlucky days composed some 3,200 years ago may be the oldest preserved historical document of the discovery of a variable star, the eclipsing binary Algol. Of the modern astronomers, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
