Orbiting Geophysical Observatory
Orbiting Geophysical Observatory (OGO) Program of NASA refers to the six satellites launched by the United States that were in use from September 1964 to 1972, designed to study the Earth's magnetosphere. The satellites successfully studied the interactions between the Earth and the Sun, despite a number of technical problems. Each satellite had 20 to 25 instruments. OGO 1, OGO 3, and OGO 5 were in equatorial orbits; OGO 2, OGO 4, and OGO 6 were in lower polar orbits.

Near-Earth Object
A near-Earth object (NEO) is any small Solar System body whose orbit brings it into proximity with Earth. By convention, a Solar System body is a NEO if its closest approach to the Sun (perihelion) is less than 1.3 astronomical units (AU). If a NEO's orbit crosses the Earth's orbit, and the object is larger than across, it is considered a potentially hazardous object (PHO). Most known PHOs and NEOs are asteroids, but a small fraction are comets. There are over 30,503 known near-Earth asteroids (NEAs) and over a hundred known short-period near-Earth comets (NECs). A number of solar-orbiting meteoroids were large enough to be tracked in space before striking the Earth. It is now widely accepted that collisions in the past have had a significant role in shaping the geological and biological history of the Earth. Asteroids as small as in diameter can cause significant damage to the local environment and human populations. Larger asteroids penetrate the atmosphere to the surf ...

Spartanburg Herald-Journal
The ''Spartanburg Herald-Journal'' is a daily newspaper, the primary newspaper for Spartanburg, South Carolina, United States. History The origins of the paper lie with ''The Spartan'', a weekly paper reportedly first printed in about 1842–43. In 1844, this was renamed ''The Carolina Spartan''. In about 1900, the paper was reportedly bought by The Journal Publishing Company, which renamed it ''The Spartanburg Journal''. In 1872 (or perhaps 1875), ''The Spartanburg Herald'' began publishing. It began daily publication in 1890; the ''Journal'' followed suit in 1903. The ''Herald'' purchased the ''Journal'' in 1914. The ''Herald'' was a morning paper, while the ''Journal'' covered evenings, with joint editions published on the weekend. Though under common ownership, the ''Herald'' and ''Journal'' did not completely merge into one paper until October 1982. In 1929, owner The Herald-Journal Publishing Company sold the papers to its paper distributor, the International Paper an ...

The Modesto Bee
''The Modesto Bee'' is a California newspaper, founded in 1884 as the ''Daily Evening News'' and published continuously as a daily under a variety of names. Before its purchase by Charles K. McClatchy and McClatchy Newspapers in 1924, it merged in the same year with the ''Modesto News-Herald'', adopting that name as part of a consolidation. In 1933 it changed its name to the ''Modesto Bee and News-Herald'', and in 1975 abbreviated the name on its masthead to ''The Modesto Bee''. Its current owner is the descendant firm, McClatchy Company, an American newspaper corporation.

Hopkinsville, KY
Hopkinsville is a home rule-class city in and the county seat of Christian County, Kentucky, United States. The population at the 2010 census was 31,577. History Early years The area of present-day Hopkinsville was initially claimed in 1796 by Bartholomew Wood as part of a grant for his service in the American Revolution. He and his wife Martha Ann moved from Jonesborough, Tennessee, first to a cabin near present-day W. Seventh and Bethel streets; then to a second cabin near present-day 9th and Virginia streets; and finally to a third home near 14th and Campbell. Following the creation of Christian County the same year, the Woods donated of land and a half interest in their Old Rock Spring to form its seat of government in 1797. By 1798, a log courthouse, jail, and "stray pen" had been built; the next year, John Campbell and Samuel Means laid out the streets for "Christian Court House". The community tried to rename itself "Elizabeth" after the Woods' eldest daughter, but a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Comet Bennett
Comet Bennett, formally known as C/1969 Y1 (old style 1970 II and 1969i), was one of the two bright comets observed in the 1970s, along with Comet West. The name is also borne by an altogether different comet, C/1974 V2. Discovered by John Caister Bennett on December 28, 1969 while still almost two AUs from the Sun, it reached perihelion on March 20, passing closest to Earth on March 26, 1970 as it receded, peaking at magnitude 0. It was last observed on February 27, 1971. Observational history The comet was discovered by John Caister Bennett on 28 December 1969 from Pretoria, South Africa, during his comet seeking routine. The comet was located in the costellation Tucana, in 65° south declination, and had an estimated magnitude of 8.5. At that time the comet was about 1.7 AU both from the Sun and the Earth. The orbit was computed by M. P. Candy of the Perth Observatory and it became apparent that the comet could became a bright object by the end of March, during its periheli ...

Akihiko Tago
is a Japanese amateur astronomer. He co-discovered several comets, including C/1968 H1 (Tago-Honda-Yamamoto), C/1969 T1 (Tago-Sato-Kosaka), C/1987 B1 (Nishikawa-Takamizawa-Tago). At the Satsuki Observatory established in 1996, Tago has supported and encouraged amateur astronomers in Yanahara, Okayama. Asteroid 7830 Akihikotago was named to honor his dedication. He also discovered several novas, includinV1493 Aql (Nova Aquilae 1999)V2275 Cyg (Nova Cygni 2001 no. 2)V574 Pup (Nova Puppis 2004)V2467 Cyg (Nova Cygni 2007) anV459 Vul (Nova Vulpeculae 2007 no.2). In 2006 he was the first astronomer to discover a micro-lensing system outside the Magellanic Clouds and the bulge of our Milky Way. The star GSC 3656-1328 suddenly brightened by four magnitudes in two weeks time and returned to its normal brightness two weeks later. A red or a brown dwarf star passed exactly in front of GSC 3656-1328 and the gravity of the dwarf star directed more light to the observers on Earth. He lives ...

Comet Encke
Comet Encke , or Encke's Comet (official designation: 2P/Encke), is a periodic comet that completes an orbit of the Sun once every 3.3 years. (This is the shortest period of a reasonably bright comet; the faint main-belt comet 311P/PanSTARRS has a period of 3.2 years.) Encke was first recorded by Pierre Méchain on 17 January 1786, but it was not recognized as a periodic comet until 1819 when its orbit was computed by Johann Franz Encke. Like Halley's Comet, it is unusual in its being named after the calculator of its orbit rather than its discoverer. Like most comets, it has a very low albedo, reflecting only 4.6% of the light its comet nucleus, nucleus receives, although comets generate a large coma (cometary), coma and tail that can make them much more visible during their perihelion (closest approach to the Sun). The diameter of the nucleus of Encke's Comet is 4.8 km. Discovery As its official designation implies, Encke's Comet was the first periodic comet discovered af ...
